First, the high yield scheme, the need for stronger hardware configuration, the basic configuration requirements of the outer pond equipment (mu output of 1500 ~ 2500 jin)
1. Aeration configuration: (The aeration plate mentioned below has 5 meters long nanotubes on each plate):
Principle: 1000 kg of shrimp production per 1 kW of power;
(1) For earthen ponds with a yield of 1500 jin or less per mu, the water distribution wheel is 1.5 kW/mu (the recommended jet aerator with a water depth of 1.5 meters is 1.5 kW/mu), and vortex water flow is formed as much as possible;
(2) Mu yield 2500 jin of earthen pond:
(1) Scheme 1: at least 24 nano aeration disks/mu (power configuration of 1.5 kW rotary blower) + 0.75 kW water wheels, a total of 3.0 kW / mu;
(2) Scheme 2: Or directly use two 1.5 kW jet aerators, that is, 3.0 kW/mu; this scheme is more convenient and simple to operate, equipment maintenance is also very simple, and the effect can be achieved;
<col>
This figure shows the configuration of the bottom aeration device
High-yield planning 1500-2500 jin / mu hardware configuration, must use bottom aeration equipment, or jet aerator underwater aeration equipment;
The picture shows 1.5 acres, 2 sets of 0.75 kW water wheels + plus a 1.5 kW jet aerator
Pond treatment methods for releasing seedlings (see Table 1)
1. After disinfection from the bottom bleaching powder, control the seedlings in about 7 to 10 days:
If the delay is too long, a large number of natural enemies will be generated: such as dragonfly larvae, water centipedes, large tadpoles, etc.; if the time is too short, there may be toxin residues, as well as insufficient algal phases and natural food, and the ecosystem is not rich;
Table 1: "Tutang Plan B": Water before putting shrimp fry in the outer pond: disinfection and salt adjustment PH-bacterium cultivation operation table
Purpose and principle of operation
Product operation methods and precautions (taking freshwater shrimp farming inland as an example)
1. Dry pond and clean pond base - silt disinfection - reserve total alkalinity and calcium and magnesium;
(1) Weed removal→ debris → trim the bottom (it is best to plough it, the small pond should be repaired to the bottom of the pot) → slope protection→ wash the black mud organic matter with a water gun, if there is enough time, you can dry the pond for a period of time (during the period of long grass, it should also be removed);
(2) Silt disinfection: after washing the black silt, take advantage of the wet soil state, timely and evenly sprinkle about 100 kg/mu of quicklime, disinfect the silt, or soak and disinfect the water for about 10 cm for 2 days;
(3) The total alkalinity and natural calcium and magnesium of the inland freshwater soil pond reserve: at the same time, within 3 meters around the pond, evenly sprinkle 1000 kg/mu of dolomite powder, it is best to go down artificially to deep plough and mix with the silt;
Notes:
(1) If the shrimp has hepatosporus, drain the water, repeatedly rinse with a water gun at least 2 times, then dry the pond disinfection, the quicklime increases to 400 kg /mu (or with the fire alkali caustic soda 50 kg/mu for assistance), and the silt is fully mixed and deeply cultivated, and then 10 to 20 cm of water is soaked and disinfected for more than 2 days, and then the extubation is discharged or drained (otherwise the alkalinity is too heavy, and it is difficult to reduce the PH value in the follow-up), and then rinse with water again;
2. Water inlet
(1) Inland freshwater area: advanced water 0.5 to 0.7 meters: this can save salt brine or sea salt and minerals;
(2) Coastal brackish water areas or saline areas: the water inlet reaches a depth of about 0.5 to 1.8 meters, and can be filled with water at one time;
(1) Pay attention to the water inlet pipe to prevent small trash fish from entering with 100 mesh fine nets;
3, with water disinfection - remove residual chlorine - adjust salinity - add mineral elements
(1) Disinfection: use bleach powder 25 ~ 50 kg / mu 1 meter water depth, smouldering for more than 12 hours;
(2) Remove residual chlorine: after 12 hours, the aerator or aeration can be opened to promote the volatilization of residual chlorine;
(3) Adjust salinity and add mineral elements: while driving water wheels or aeration to remove residual chlorine, sea salt (or salt halogen) + "complex calcium magnesium potassium bromobron mineral elements" can be added;
(4) Detoxification: After 3 days of opening the aerator, 2 kg/mu of large soda (sodium thiosulfate) can be used to remove possible residual chlorine residues;
(1) It is advisable to release shrimp fry within 7 to 10 days from the beginning of disinfection with bleaching powder;
(2) Pay attention to the order, first bleach powder disinfection, and then add sea salt (or salt brine) + mineral elements;
4. Freshwater shrimp farming area in the mainland: salinity regulation + mineral element blending (simulating seawater)
The adjustment of salinity is based on the salinity of shrimp fry after coarseness and dilution: suppose that the salinity is 2.5 ‰, and the water depth is 0.6 meters when the seedlings are released as an example (that is, an acre of 400 cubic meters of water body, and the subsequent water depth will be slowly deepened)
(1) Method 1: Sea salt + "complex calcium, magnesium, potassium, bromide boron mineral elements" (for inland freshwater soil ponds)
"Tutang Plan B" plans to add about 2000 jin / mu of added amount: per mu: sea salt 800 kg + "composite calcium magnesium potassium bromobron mineral elements" 400 kg, which can be adjusted to about 2.5 ‰ salinity;
The cost of adding 1200 yuan / mu, the cost per kilogram of shrimp is 0.6 yuan / catty;
If the water source is surface water, after the above adjustment, it can generally reach: calcium 90ppm, magnesium 130ppm;
If the water source is groundwater, calcium and magnesium will be much higher;
(2) Method 2: Salt halide + "complex calcium, magnesium, potassium, bromide boron mineral elements" (for inland freshwater soil ponds)
"Tutang Plan B" plans to add about 2000 jin / mu of the added amount: per mu to add: salt halogen 4000 kg + "complex calcium magnesium potassium bromobron mineral elements" 400 kg, which can be adjusted to more than 4.0 ‰ salinity;
Add the cost of 3000 yuan / mu, the cost per kilogram of shrimp 1.5 yuan / catty;
If the water source is surface water, after the above adjustment, it can generally reach: calcium 120ppm, magnesium 180ppm;
If it is groundwater, calcium and magnesium will be much higher;
(3) Method 3: Directly mix with seawater
Close to the sea, where there is a ship, you can directly use a tugboat to transport seawater in and into the pond for mixing;
(1) It is strongly recommended to use method 2 in freshwater soil ponds in the mainland, that is, the method of salt brine, and the success rate of shrimp farming is very high;
(2) Sea salt and salt brine sources are very important, it is best to find people who have used to recommend the source of goods, or personally to investigate the qualifications of the salt farm, this is very important, if you use inferior sea salt and salt brine, I am afraid that the whole army will be destroyed;
(3) The above earthen ponds with sea salt or salt brine, after raising a shrimp, try to retain the water body, and leave it to the next year to raise shrimp to save costs, that is, a pond of water breeding more shrimp to save costs;
(4) The formula of "complex calcium magnesium potassium bromobron mineral elements": magnesium chloride hexahydrate 50 kg, calcium chloride dihydrate 7 kg, potassium chloride 2.5 kg, potassium bromide 0.5 kg, boric acid 0.15 kg; a total of 60.15 kg; artificial stirring evenly, standby can be;
5. Adjust the total alkalinity of the water body
Freshwater shrimp farming in the interior does not need to adjust the total alkalinity before releasing seedlings, and there is no need to toss it again:
(1) After the reserve of 1000 kg/mu of dolomite powder in the silt in the front, and the sea salt (salt halogen) and the "complex calcium, magnesium, potassium and bromobomer mineral elements" are dissolved later, the total alkalinity of the water body at this time is generally more than 120ppm, and there is no need to toss it anymore;
(1) Before releasing seedlings, do not directly sprinkle calcium carbonate, shell powder, dolomite powder and other powder raw materials into the water body to adjust the total alkali test, because the shrimp fry intestine is too small, and after swallowing these powders by mistake, it will affect the intestine and cause gills problems;
(2) In fact, it is difficult to adjust the total alkalinity in the freshwater areas of the interior, which can be slowly increased after 30 days of shrimp fry, and only after 30 days of seedlings can be directly splashed with water with powder products such as dolomite powder, to raise prawns and high yields, there is no total alkalinity support is also not feasible;
6. Control phH
(1) The PH of seedlings is best controlled within 7.8~8.5 in the afternoon;
(2) If the PH is high, citric acid can be used 5 to 25 kg/mu per water, and it can be adjusted, and it will not work again once;
(1) At any cost, the PH before the seedlings should be reduced to less than 8.5 (citric acid monohydrate), otherwise the salt halogen and "complex calcium, magnesium, potassium, bromoboron mineral elements" added at a large cost in front of the large cost, etc., the effect will be greatly reduced, because the PH is too high, the magnesium ions are insoluble, and they cannot be detected with conventional detection;
(2) Some farmers buy sodium citrate, which in turn causes PH to rise (weak acid), do not buy wrong;
7. Culture of bacteria
After the 3rd day of disinfection of bleach powder, the cultivation of high lactic acid bacteria phase can begin (with detoxification effect)
(1) Culture: do high lactic acid bacteria phase, use "strong micro-seedling emergency lactic acid bacteria phase" 500 g / mu + brown sugar 3 ~ 5 kg / mu + water about 50 kg, soaking and activating for 5 hours, if you can inflate and activate 5 hours The effect is better;
(1) "Seedling emergency lactic acid bacteria phase" can also be replaced by "lactic acid bacteria expansion liquid" 50 kg/mu, sprinkled on the water wheel, the cost is lower; the production method of "lactic acid bacteria expansion liquid" is at the end of this article;
(2) Cultivate the bacteria first, and then cultivate the algae (see the next column for cultivating algae)
8. Cultivate algae fertilizer and hydroponic insects
The day after the cultivation of bacteria: start cultivating rich natural bait and algae, let the shrimp fry win at the starting line, use "fermented nitrogen fertilizer", there are the following options, of which "fermented fish sauce" is better:
(1) "Strong micro-cultured algal enzyme" 1 ~ 3 kg / mu, according to the situation again;
(2) "Fermented fish sauce" 10 kg/mu, and use it again 1 to 3 times according to the situation;
(3) "Liquid fermented nitrogen fertilizer" "15 kg / mu, according to the situation to use 1 to 3 times;
(4) "Solid fermented nitrogen fertilizer" 10 kg/mu, and use 1 to 3 times as appropriate;
(5) "Fermented wheat bran or rice bran liquid fertilizer" 10 kg / mu, continuous use for several days;
(6) "Fermented egg duck or layer chicken or suckling pig feed liquid" 10 kg /mu, instead of shrimp milk powder, continuous use for several days, the method is shown in the table note;
(1) Cultivated to the naked eye observation: water color yellow-green, emerald green, tea brown, tea green, shiny and sparkling, fat and tender, feel happy until;
(2) First cultivate bacteria (the previous column), then cultivate algae, do not engage in reverse; "fermented nitrogen fertilizer" also has a detoxification effect;
9. Complex heavy metals before seedling release;
Sprinkle disodium EDTA or tetrasodium complex heavy metals before seedling release:
(1) The dosage of disodium EDTA is 2~3 kg/mu;
Precautions: Especially with underground water sources, we must pay attention to the treatment of heavy metals;
10. After the 7th day, the seedlings can be put into the outer pond;
There are several sources of shrimp fry:
(1) Purchase of professional fry farms that have been diluted to 0.5 to 3.5 ‰ shrimp fry for direct placement;
(2) Purchase P5 aviation shrimp fry, there are indoor standard coarse dilution conditions, can be diluted indoors or add the standard thickness for 10 to 25 days, and then directly put the seedlings in the outer pond, there is time and conditions, it is best to mark larger, such as 3 cm or more, and then directly put the seedlings to the outer pond;
Note to this table:
(1): There are standard rough and diluted conditions, it is highly recommended to purchase high salinity P5 air shrimp fry, to dilute and appropriately mark the thickness, the reasons: one is the high survival rate after the pond, how many shrimp in the pond, the heart is numbered; the second is insurance, if you use the source of the first shrimp fry above, you may have only found out after 1 month that there is no shrimp in the pond, but time and energy have been wasted;
(2) "Liquid fermented nitrogen fertilizer" and "solid fermented nitrogen fertilizer" production: 1 pack of "strong micro aquatic carbon fertilizer nitrogen fertilizer starter" + 1 pack of "strong micro water fine cui" + 200 kg of protein raw materials (soybean meal powder, cotton or rapeseed cake peanut cake powder, fish meal, small miscellaneous fish syrup, high-quality animal scraps) + corn flour or dried potato powder or starch 50 ~ 150 kg + brown sugar 10 kg, add water to adjust the water content of about 50%, the more animal raw materials, the more starch raw materials added, the water content is determined to be liquid or solid, Adding water is mostly liquid is liquid fermentation, adding water is less solid is solid fermentation; some odors are normal;
The fermentation of "liquid fermented nitrogen fertilizer" is more thorough, and in the summer it is recommended to use a liquid fermentation method (more water);
(3) The production of "fermented fish sauce": 1 pack of "strong micro aquatic carbon fertilizer nitrogen fertilizer fermentation agent" + 1 pack of "strong micro water fine green" + 100 ~ 200 kg of pulp made of small miscellaneous fish + corn flour 100 kg + brown sugar 10 kg, and then stir evenly, and then add water to immerse the material while stirring, you can seal the fermentation (do not spin to death with a screw cap, so as not to explode), can be successfully fermented in just about 20 days (referring to summer); and there is no odor;
(4) The production of "fermented wheat bran or rice bran liquid fertilizer": 1 pack of "strong micro aquatic carbon fertilizer nitrogen fertilizer fermentation agent" + 1 pack of "strong micro water fine green" + 100 kg of wheat bran (or polished rice bran) + 500 kg of water + brown sugar (or glucose or white sugar) 10 kg, fermentation in the summer for 2 to 5 days, fermentation to ABOUT PH4, sealed in a cool place can be stored for one month; the taste is extremely sour and has a wine taste, and some odors after a long storage time are normal;
(5) "Fermented egg duck or suckling pig feed" production: 1 pack of "strong micro aquatic carbon fertilizer nitrogen fertilizer fermentation agent" + 1 pack of "strong micro ammonia beautiful water lactic acid bacteria phase" + 40 kg of egg and duck feed + 150 kg of water + 7.5 kg of brown sugar, sealed fermentation for 4 to 5 days, shrimp fry will be fed on the second day, every 100,000 shrimp fry poured 1 to 2 kg / day, even water belt duck feed 1 ~ 2 kg / day;
Instead of shrimp milk powder after the seedlings are released, it can be fed directly; depending on the water color, it is fed 1 to 2 kg/mu/day per day, with the effect of cultivating algae fertilizer water and insects, increasing the natural bait of the pond, the shrimp intestine and liver and pancreas are clear and thick;
Arable land and implantation of dolomite powder in silt (this may be the only mineral containing both calcium and magnesium)
2. Freshwater shrimp farming in the inland: a pond of water breeds more shrimp
Shrimp farming is good, or just a little problem, in this case, you can not use the dry pond to dredge, and then raise a shrimp can be;
Especially for the freshwater shrimp farming areas in the interior, this is very important, after all, when raising shrimp, sea salt (or salt brine) with a value ranging from 2000 to 3000 yuan / mu is added + "complex calcium, magnesium, potassium bromobomer mineral elements", etc., to preserve these waters, which can save a lot of costs;
Especially has been the use of strong fine-tuning water concept, the bottom of the silt is relatively clean, so directly follow the old pond water can be, in the Fujian Zhangzhou area, water shortage area with strong micro products, a pond of water the highest record raised 6 shrimp;
After the shrimp are raised, do the following:
Table 2: The water used to make shrimp is used to raise the next shrimp, and the water quality treatment before the seedlings are released
1. Disinfection
(1) The shrimp were raised very smoothly, and there was no Vibrio and shrimp disease: on the first day, for the bottom silt, 20% potassium persulfate composite salt granules were used first 1000 g/mu, and the sludge was oxidized and disinfected once; the next day, about 15% chlorine dioxide effervescent tablets could be used for treatment of 500 g/mu;
(2) There is still a little problem in making shrimp: after the shrimp, disinfect immediately: use 50 kg of bleaching powder / mu, disinfect with water, after one day, use granular sulfur preparations or chlorine dioxide tablets, carry out bottom oxidation and bottom disinfection 1 to 3 times, etc.;
2. Replenish salinity - mineral elements
(1) First test the salinity, not enough 4.0 ‰ ("Tutang Plan B" is highly demanding), you can decide to add sea salt or salt brine through calculation;
(2) Re-test the calcium and magnesium content, not enough calcium 100ppm, magnesium 150ppm ("Tutang Plan B" is highly required), and then use "complex calcium magnesium potassium bromobron mineral elements" to make up for it;
(1) Add 1 kg of sea salt or 2.5 kg of salt brine per cubic meter of water, which can increase the salinity by 1‰;
(2) Add 100 grams of "complex calcium magnesium potassium bromoborm mineral elements" per cubic meter of water, which can increase calcium by 3ppm and magnesium by 10ppm;
3. Adjust the total alkalinity
Because the water has been filled with ponds, it is impossible to implant dolomite powder in the silt at this time, so it is impossible to adjust the total alkalinity;
And it is also not possible to directly sprinkle dolomite powder or calcium carbonate powder or shell powder, because shrimp fry will be released soon, and these powder products may block the parotid glands and intestines of shrimp fry;
The adjustment of the total alkalinity can be ignored for the time being; it is too low, and it can be temporarily adjusted with baking soda 15 kg/mu;
4. Adjust the PH value
(1) Ph.D. needs to be controlled between 7.8 and 8.5;
(2) If the PH is high, it can be directly adjusted with citric acid 5 to 25 kg/mu a water;
(3) If the PH is low, it can be directly adjusted with 5 kg/mu/time of quicklime, a small number of times;
5. Culture of bacteria + culture of algae: first cultivate bacteria and then cultivate algae
After cultivating the bacteria and cultivating the algae, the seedlings are released
(2) Algae cultivation: use "fermented nitrogen fertilizer" 5 to 15 kg / mu, or "strong micro-culture algae enzyme" 1 ~ 3 kg / mu, according to the situation, cultivate algae 1 to 3 times, observe the fertilizer is tender and refreshing, the water color is good;
(2) Production of "fermented nitrogen fertilizer": see Note 7 above;
6. Detoxification + seedling release
(1) Where the water quality is not good, especially if a large amount of well water is replenished, it is recommended to treat the seedlings with EDTA disodium 2 kg/mu the day before the seedlings are released;
(2) Then put the P10 shrimp fry directly according to the specification, or put the shrimp fry after diluting the coarseness;
Test seedling barrel, put 10 shrimp fry, can be observed for 10-20 days, to judge the vitality of shrimp fry in the pond, test seedling barrel without feeding
In the freshwater areas of the interior, the method of direct release of seedlings is a last resort, and it is only used when there is no dilution of the standard thickness, and the desalinated shrimp fry of the shrimp nursery of about P10 can be put;
Third, after the release of seedlings: mixing in the feed for health care - method of conditioning the intestine;
1. Introduction and Suggestions:
It is recommended to purchase a mixer for the use of mixing materials plus medicine and water fermentation, etc., and the labor intensity of the mixing materials is small;
(1) Microbial intestinal products: It is recommended to add Clostridium butyrate and lactic acid bacteria to the shrimp feed for a long time, which has great benefits for reducing the ratio of material to meat, increasing the intestinal thickness, improving digestion, enhancing immunity, and reducing white stool enteritis:
(2) Nutritional and functional additives: It is also recommended to use aquatic multivitamin products (long-term use) + bile acids (used in the hepatic period), + conditional can add marine red yeast or rain red chlorella products or other products rich in astaxanthin to improve body color, improve immune resistance, improve anti-stress ability, etc.;
(3) When strong stress, shrimp need to consume a lot of energy, at this time can consider the water body can be sprinkled with a large amount of vitamin C and conventional sprinkling of trace elements, sugars, baking soda 3 kg / mu, sea salt 5 kg / mu (inland freshwater shrimp farming) and other anti-stress products;
(4) Freshwater shrimp farming in the mainland, most of which may appear that shrimp are not fat, there is no meat feeling, and the current shrimp commodity feed nutrition on the market is not comprehensive, and even the phenomenon of insufficient nutrition is more common, so it is necessary to often use some nutrient fortification mixtures in the middle and late stages, such as "fermented fish sauce" or "fermented worm pulp protein" or other nutrients;
2. There are two options for adding routine health care as follows:
(1) The first meal is used at 7:00 a.m.: add "Changding-5" with 2 grams + "strong micro-aquatic glycosides" 0.5 to 1 grams per kilogram of feed; first use 20 to 30% of the feed amount of water-soluble products, and then sprinkle into the feed, after a few minutes, let it penetrate into the feed, and then feed; or let it stand for fermentation within 3 to 12 hours, pay attention not to exceed the time, so as not to over-ferment;
(2) The second meal is used at 11:00 noon: bile acid + aquatic professional vitamin + marine red yeast 10 ml / kg feed mixture; bile acid is used in the early stage of breeding, which can be used in the middle and late stages, and vitamin products are used throughout the whole process; astaxanthin products ("strong micro high-energy fermentation red carbon source", etc.) can be selectively used (factory recommended for full-term use)
(3) The third meal is used at 15:00: the same as the first meal;
(4) The fourth meal is used at 19:00: the same as the second meal;
3. Or add a meal of fermented feed feeding method
This method replaces the meal in the above protocol where "Changdine-5" and "strong micro-aquatic glycosides" are added;
This method has a better effect, greatly increases the amount of food collected, has strong disease resistance, and helps the shrimp to molt, especially to help the rapid recovery of hard shells after shelling, which can reduce the chance of shelled shrimp being attacked by pathogens and similar attacks;
Fermentation method: 1 package of "strong micro aquatic feed starter", 100 kg of shrimp feed, add 30 kg of water, strictly seal the fermentation for 6 to 12 hours, and feed within 24 hours; if the fermentation time exceeds 1 day, it is recommended to account for only less than 50% of the feeding amount.
Precautions: If the method of fermentation is used, pay attention not to over-fermentation, and feed it according to the time specified above;
If you are too busy and forget the fermentation time, the feed that has been fermented over-fermented can only be mixed and fed, mixed with 10 to 50% to feed; otherwise, the long-term use of fermentation material that exceeds the specified time to feed, but it will cause the shrimp intestinal flora to be single, resulting in thinning or disjointed intestines, but of course, once this occurs, immediately resume the prescribed operation, and in a few days it can return to normal, that is, this phenomenon is reversible;
4. Reference table for determining the daily feeding amount: Refer to the following table 2 for the specific conventional feeding amount:

Note: (1) The above is the reference feeding amount, the specific feeding amount must be judged according to the observation of the feeding table, the amount of residual bait at the bottom, etc.;
(2) The specific feeding amount is also closely related to the quality of shrimp fry, water quality and management, feed quality, dissolved oxygen, etc.;
(3) Generally four meals a day, 7:00 a.m., 11:00 noon, 15:00 p.m., 19:00 p.m.; nodes with high temperature are more invested, nodes with low temperature are less cast, No. 1 material is controlled for 1.5 hours, No. 2 material is controlled for 1 hour, and No. 3 material is controlled within 40 minutes of eating;
(4) According to their own experience, to determine the time for all the finished feeding at each stage, for example, in order to manage the water quality, so as not to exceed the sub-salt explosion table, the more to the late stage of breeding, the less time to eat the food;
Fourth, after the release of seedlings: 1-60 days or 120 days, the "Tutang B Plan" water transfer mushroom program during the grow-out period
"Silt-water body-intestine-fungal algae balance" Trinity is a strong and micro concept of using bacteria, that is, these 3 parts (silt-water body-intestine) must do a good job of ecological treatment, indispensable, and the outer pond must also achieve "bacteria and algae balance";
1. It is recommended to fully cultivate algae and insects before releasing seedlings
The use of "fermented nitrogen fertilizer" not only provides abundant natural food, but also cultivates stable and high-quality beneficial algal phases to enrich pond ecosystems;
2. Control algal phase and "fungal algae balance"
In the middle and late stages of breeding, especially in the high summer temperature period in the interior, it is necessary to control the "balance of bacteria and algae";
When the algae is thick, it is more difficult to control, in addition to using shading products such as sodium humate or professional dyeing products to deepen the water color to control the algal phase, it is necessary to adhere to the biological bottom and oxidation to change the bottom, while regularly sprinkling "lactic acid bacteria expansion solution" + "fermentation carbon source" combination to improve the lactic acid bacteria phase, is an effective way to control the algal phase, and achieve "algal balance";
When the water body is thin, the "fermented nitrogen fertilizer" is used for fertilizer hydroponic algae treatment;
3. Preventive control of ammonia nitrogen salts is critical
Prevention should be the mainstay from the beginning: the ultimate solution is to use "sub-dredging and bottom granules" (or "strong micro-water fine green" or "whole pool ecological conditioning bacteria") + "arc-clearing mud pellets" every day, mixing materials or soaking materials can be sprinkled, from beginning to end to prevent, and regularly use "strong micronitrate ammonia double compound bacteria" prevention;
4. Muddy water and control algal phase in the later stage
In the middle and late stages of high-density aquaculture, it is actually hoped that the water will become turbid, especially in the high temperature period of the inland summer, the turbid water can block the strong sunlight, so that the green algae is not thick, so that the PH can also be stabilized, and the turbid water becomes the attachment point of the high bacteriophasis, and the high bacterial phase is used to control the stability of the water quality in the middle and late stages;
Due to the activity of high-density prawns in the bottom mud in the late stage, generally after about 40 days, especially when feeding, there will be obvious muddy water, yellow-green turbid water is very good, it is normal, and it also shows that the shrimp stock in your pond is very large;
In the middle and late stages of high-temperature algae concentration, you can also use shading products such as sodium humic acid or professional dyeing products to deepen the water color, high-yield pond is worried about the late stage of thick green algae; and algae concentration is more difficult to control; super large amount of sprinkling "fermented corn or starch liquid" + "ammonia-lowering water lactic acid bacteria phase" (or "lactic acid bacteria amplification liquid") combination to improve the lactic acid bacteria phase, is one of the efficient ways to control the algal phase, so as to achieve "algal balance";
5. Other precautions
(1) It is best to control the pH below 8.6 in the afternoon throughout the whole process, so as to obtain stable water quality and high yield
(2) For freshwater shrimp farming in the mainland, the total alkalinity (water quality is more stable) should be slowly increased during the breeding process and mineral elements should be replenished regularly;
It does not matter if the total alkalinity of the seedling stage is lower, it is necessary to slowly increase the total alkalinity in the breeding process (regularly use shell powder, calcium carbonate, and dolomite powder to slowly increase);

Operating table of "Silt-Body-Body-Gut-Algae Balance"
"Tutang Plan B" shrimp farming operation for 1 to 60 or 120 days: the specific breeding cycle time, mainly depends on the temperature and varies
Use of products and purposes
The dosage and method of use of the product
1. Regular oxidation and bottom modification
(1) Use once a week on Monday: each time with chlorine dioxide tablets, or potassium bisulfate compound salt granules, or bromochlorohein tablets, or potassium perferrate, and other oxidation bottoming products that can sink to the bottom, according to their instructions with shrimp dosage to use;
Note: (1) Oxidation should be used separately from the strong microbactericide for 12 hours, and the interaction has little effect;
2. Carried out every day: ecological conditioning of the whole pond (focusing on sediment): prevention of harmful substances in sediment (salt - ammonia nitrogen and hydrogen sulfide)
(1) There are two methods of ecological conditioning of water bodies and sediment in the whole pond every day:
Method 1: use every day: "sub-dredging and bottom pellets" 25 to 50 g / mu + "arc cleaning mud pellets" 10 to 20 g / mu, after calculating the amount of use every day, and the feed mixture of a meal on the day is sprinkled into the pond, the operation is simple and convenient; the dosage range is less in the early stage and more in the later period;
Method 2: use every day: "whole pond ecological conditioning bacteria" (or "strong micro water fine cui") 25 ~ 50 g / mu + "arc cleaning mud pellets" 10 ~ 20 g / mu, after calculating the amount of use every day, and the feed of a certain meal on the day is mixed together, directly sprinkled, or soaked in water and sprinkled into the pond (and feed soaked together); the dosage range is less in the early stage and more in the late period;
Precautions: This step needs to be adhered to throughout the process (to maximize the control of ammonia nitrogen salts and nitrates)
(1) Choose one of the above two methods, which does not refer to simultaneous use; this operation is mainly aimed at sediment;
(2) In a two-way way, if it can be used interchangeably, the effect is better; the day of oxidation can not be used;
(3) The "sub-dredging and bottom-changing particles" in Method 1 can remove harmful substances from the silt (salt hydrogen sulfide ammonia nitrogen, etc.), and can slightly pick up the sediment and carry out regular substance exchange with the water body;
(4) The "whole pond ecological conditioning bacteria" or "strong micro water fine green" in Method 2 have the effect of slightly copying the sediment, so that the sediment and the water body can be exchanged regularly, and the water quality of the water body can be adjusted;
(5) The two methods of this operation can slightly pick up the sediment, thereby removing harmful substances from the sediment, but in high temperature weather, please do not use it excessively, so as not to copy the mud too large and cause side effects; low temperature weather can be doubled as appropriate;
(6) "Clearing the arc to change the mud pellet" can control the harmful bacteria and spoilage bacteria in the silt;
3. Replenish the carbon source of the water body every day, continuously maintain the mycosyst, and promote the circulation basis of the pond micro-ecological substance;
(1) Supplement the carbon source every day, and there are two ways to supplement it:
Method 1: use soluble corn starch or low gluten flour 200 ~ 1200 g / mu, take a small value in the early stage of breeding, slowly take a large value in the middle and late stage of breeding, and directly mix with a meal of feed on the day and then sprinkle, the operation is simple and convenient;
Method 2: use "fermented corn or starch liquid" 2 to 8 kg / mu (qiangwei will soon produce a professional "fermented carbon source"), take a small value in the early stage of breeding, slowly take a large value in the middle and late stages of breeding, and directly sprinkle it behind the water wheel;
(1) Choose one of the above two methods, which does not refer to simultaneous use; the use of carbon sources every day can ensure the stability of the pond microecology;
(2) "Fermented corn or starch liquid" must be used in the evening and filtered with a 100 mesh net, and the filter residue can be used to mix and feed shrimp, the effect is very good; if it is fermented with starch, it does not need to be filtered.
4. Supplement the lactic acid bacteria phase on Wednesday: it can inhibit Vibrio aqueous body and alleviate and control algal phase over-concentration;
Maintain with "ammonia-lowering water lactic acid bacteria phase" or "lactic acid bacteria spreading liquid";
(1) Method 1: Use once a week on Wednesday: "Ammonia beautiful water lactic acid bacteria phase" 500 g / mu, directly soaked in water and sprinkled, or with 2 kg of brown sugar / mu, add 20 kg of water to activate 1 to 12 hours (inflatable activation is better for 12 hours), and then directly sprinkle behind the water wheel;
(2) Method 2: Use once a week on Wednesday: "Lactic acid bacteria amplification solution" 25 ~ 50 kg / mu, directly sprinkled on the back of the water wheel, the dosage range to observe the water quality status, can refresh the water quality;
(1) Choose one of the above two methods and do not refer to simultaneous use;
5. After 20 days of seedling release, freshwater shrimp farming in the inland:
Every Friday: Supplement with mineral calcium and magnesium and adjust salinity
It belongs to the sampling project, and the problem is only handled when it is found
(1) Freshwater shrimp farming: according to the results of calcium and magnesium testing, supplement "complex calcium magnesium potassium bromobron mineral elements" about 50~100 kg/mu;
(2) Saltwater shrimp farming: according to the results of calcium and magnesium testing, supplement "complex calcium magnesium potassium bromobron mineral elements" about 25 ~ 50 kg / mu;
(1) Every Thursday test, subject to the test results, decide whether to supplement on Friday, "Tutang Plan B" needs to ensure that the calcium content in the water is more than 80ppm and the magnesium content is more than 120ppm;
(2) The formula of "complex calcium magnesium potassium bromobron mineral elements": magnesium chloride hexahydrate 50 kg, calcium chloride dihydrate 7 kg, potassium chloride 2.5 kg, potassium bromide 0.5 kg, boric acid 0.15 kg; a total of 60.15 kg, manual stirring evenly, standby;
For each supplement of 50 kg/mu 1 meter deep, magnesium can be increased by 7.5ppm and calcium by 2.5ppm;
(3) It is best to control the PH within 8.5 in the breeding process to ensure the solubility of magnesium in water;
6. Through the detection of water quality data, timely targeted removal of harmful substances:
Remove nitro nitrogen (referring to nitrites and nitrates) and ammonia nitrogen with "nitrate double decomplex bacteria";
Continuous sampling of ponds, the discovery of ammonia nitrogen - sub-salt, timely treatment, while regular detection of nitrate, to prevent the nitrite crisis that may erupt at any time, after the discovery of the treatment method:
(1) With "nitrate double-decombine bacteria": 500 g / mu + 3 ~ 5 kg of brown sugar / mu + 30 ~ 50 kg of water, after 18 hours of inflating activation at night, the next day during the day to sprinkle behind the water wheel;
(1) Pay attention to the use of large-scale aeration equipment cooperation;
(2) When there is no ammonia nitrogen salt-nitrate, this operation can be avoided;
(3) Farmers are best able to detect nitrate, although it is low toxicity, but after accumulating too much, there is also toxicity, and at the same time may be converted into sub-salt at any time, which is a time bomb, harmful to aquaculture; it is recommended to detect nitrate at least once a week, and when nitrate is detected, it can also be treated with this method;
(4) If the content of ammonia nitrogen salt is higher, the more brown sugar is used, and vice versa, the amount of brown sugar can be reduced;
7. When the water is black and smelly, and the material is slow for unknown reasons in the later stage
(1) In severe cases, use "hydrogen desulfide composite bacteria" 200 g / mu + brown sugar 2 ~ 3 kg / mu + water about 30 kg, soak and activate for 1 to 6 hours, evenly sprinkled, can be alleviated;
(2) When preventing hydrogen sulfide in the middle and late stages, it is also possible to supplement the "strong micro-desulfuride composite bacteria" once every Tuesday and Saturday for 100 g/mu, and directly sprinkle it after soaking in water;
8. Methods for maintaining the balance of bacteria and algae:
Water thin on the cultivation of algae operation;
If the water is thick, use carbon source + fungal agent lean water;
The water is too concentrated and accompanied by a super high PH, a large amount of carbon source + decomposition agent + sodium humate is used;
(1) If the water body is thin, it is better to splash "strong micro-cultivated algae enzyme" 1 to 3 kg/mu or "fermented nitrogen fertilizer" 5 kg/mu, and cultivate algae fertilizer water, and it is better to have high-quality algae seeds to use;
(2) If the algae phase is particularly thick, and even cyanobacteria and high PH appear, then sprinkle "fermented corn or starch liquid" 25 to 50 kg / mu (pH and carbon source) + sodium humic acid 1 ~ 3 kg / mu (shade) + "thick green and blue naked algae" 1 pack of 2 acres, and drive a water wheel to maintain the flow of water, and it is appropriate to sprinkle in the evening;
Where the high-quality water source is sufficient, 10 cm of water on the surface can be pumped out and the water treatment can be appropriately replaced;
(3) Eutrophication, dirty foam, etc., with "strong micro-stain turbidity cooling" 250 g / mu treatment several times;
(4) If the water becomes too thin again: return to step (1) of this column, and repeat the cycle;
(1) Among them, "fermented corn or starch liquid" must be filtered with a 100 mesh net and used in the evening; while the filter residue can be used to mix and feed shrimp; if it is fermented starch liquid, it is not necessary to filter; if it is starch fermentation, it is not necessary to filter treatment; if it is starch fermentation, it is not necessary to filter treatment;
9, PH is king
Try to control the PH afternoon is also within 8.5, the success rate is high, stable production and stable water; when the PH is too high, the treatment:
(1) Simple and rude, directly use citric acid 5 kg / mu / time, once in the morning, once in the afternoon, not again in the evening; it should be said that this method is more straightforward and the cost is lower;
10. Pay attention to the total alkalinity
Freshwater shrimp farming "Tutang Plan B" has a total alkalinity of 80, preferably 100 ppm, and when the total alkalinity is detected below 80, it can:
(1) The following powder raw materials can be used only after 20 days of seedling release: 25 kg of dolomite powder or shell powder or light calcium carbonate can be sprinkled continuously for replenishment;
Notes:
(1) Within 0 to 20 days after the seedlings are released, the above powder products should not be used, otherwise it may cause gill glands and intestinal blockages in the shrimp; the above powder products can only be used after 20 days;
11. Cutting type sewage suction pump sucks sewage
Regular sewage suction operations begin after 30 days of seedling release:
Put a cut-type sewage suction pump in the lowest depression of the pond, once a day in the morning and once in the evening, turn on the suction pump, pump out the sewage, smell the sewage pumped out, there is a smell (hydrogen sulfide smell) and manure dirt, in any case, it is a huge help to you;
It is best to make a pond pot-shaped bottom, and then dig a pit in the middle, fix a basin, put the sewage suction pump in it, and the cutting type suction pump can break the shrimp shell and suck it out;
12. Handling of rainy weather:
(1) Conventional short-term light rain, pay attention to more oxygenation, can maintain the normal amount of feeding;
(2) Long-term light rain, often open an aerator, if the PH is much lower, you can use a baking soda powder 3 ~ 5 kg / mu (or quicklime 5 ~ 10 kg / mu) to adjust the pH value, and appropriately add some sea salt to supplement salinity;
When encountering sunlight, immediately sprinkle "strong micro-culture algae enzyme" 1 to 3 kg /mu + appropriate amount of algae seeds to cultivate algae in time;
(3) If it is after heavy rainstorms: 5 kg of baking soda per mu (or 10 kg/ mu of quicklime) + 10 to 25 kg of sea salt, improve the PH value of the pool water and salinity and total alkalinity, and also carry out the operation of cultivating algae and cultivating bacteria according to the above when there is sunlight;
Use a primary oxidation modification (persulfur particles, etc.) as appropriate to increase the bottom redox potential;
(4) In the event of Vibrio and shrimp intestinal problems, emergency treatment can be made with "strong micro-seedling rescue lactic acid bacteria phase" 500 g /mu + brown sugar 3 kg/mu; the mixture is doubled to 5~10 g/kg feed with "strong micro-lactic acid butyric acid mixing treasure", and at the same time sprinkled with "clear arc mud pellets" 100 g/mu;
On the left side of the picture above is the extubation discharge outlet (covered with a 30 mesh screen when raising shrimp), and on the right is the basin-shaped pit with a cutting suction pump
Fifth, encounter the treatment method of ammonia nitrogen and nitrite
Table 5: Principles and methods of stubborn ammonia nitrogen and nitrite exceeding the standard of shrimp culture in strong microtreatment
The main cause of ammonia nitrogen and nitrite exceeding the standard
Operation processing method
1. Management problems: (1) excessive feeding; (2) insufficient dissolved oxygen; (3) unsmooth sewage discharge;
(1) Reduce the amount of feeding, and in the summer, there is no leftover after eating in 1 hour;
(2) Check whether the aerator configuration is sufficient, insufficient reinforcement, or after a few days of sodium carbonate;
(3) Strengthen the operation of sewage suction and sewage discharge with sewage discharge conditions, and check the sewage collection capacity of ponds (sometimes the sewage collection function is insufficient, resulting in empty discharge of sewage);
(4) Without sewage discharge conditions, enhance oxygenation, and cast potassium bisulfate and other oxidation bottoming products;
2. The method of exhausting stubborn ammonia nitrogen and nitrite in one net:
The use of "nitroammonium biscombular bacteria" contains a complete "short-range nitrification and denitrification system" strain;
(1) A net to exhaust the stubborn ammonia nitrogen and nitrite method: 500 grams of "nitrate double decombine bacteria" per mu + brown sugar or white sugar 3 to 5 kg (or molasses 5 to 10 kg) + water 30 to 50 kg, put a gas stone for inflatable activation for more than 18 hours to activate the nitrogen removal function; and then evenly sprinkle into 1 mu of pond (regardless of water depth), generally 1 time can solve the problem, if not, it will be treated again in a few days;
(1) The more sugar is used, the better the effect, in addition, if you have sodium trihydrate as a raw material, you can use 2 to 5 kg / mu, while the amount of the above activated sugar and water can be reduced by half, but sodium acetate is directly spilled into the pond alone, do not use to activate the bacteria;
(2) Refractory sub-salt refers to: after the conventional "anaerobic denitrification bacteria" + "desulfurized hydrogen compound bacteria" treatment, when the phenomenon of nitrite rises first and then falls, that is, a lot of nitrate accumulated in the sediment needs to be converted into sub-salt first, which is called refractory sub-salt exceeding the standard;
3. Treatment method mainly for stubborn ammonia nitrogen
There are two treatment methods for ammonia nitrogen:
(1) Method 1: per acre: "strong micro-ammonia reduction beautiful water lactic acid bacteria phase" 500 grams + brown sugar 3 ~ 5 kg + water 30 ~ 50 kg, water temperature at least 20 ° C or more, inflatable activation for more than 18 hours, the whole pool spilled;
(2) Method 2: Per mu: "strong micro-factory special nitrogen removal bacteria" 500 grams + brown sugar 3 ~ 5 kg + water 30 ~ 50 kg, water temperature of at least 20 °C or more, inflatable activation for more than 18 hours, the whole pool spilled;
(1) Brown sugar can also be replaced with double the amount of molasses, or replaced with "fermented corn or starch liquid" 15 to 25 kg/mu; within the range of dosage, the more serious the dosage, the greater the amount, or even more;
(2) Carbon source: conditionally, it can also be combined with a small amount of sodium acetate instead of a small amount of brown sugar;
(3) Cooperate with the large-scale opening of the aeration equipment;
4. Treatment method mainly for stubborn nitrite
There are two treatment methods for nitrite-based treatment:
(1) Method 1: per mu: "strong micro aerobic denitrification denitros bacteria" 500 grams + brown sugar 3 ~ 5 kg + water 30 ~ 50 kg, water temperature at least 20 ° C or more, inflatable activation for more than 18 hours, the whole pool spilled;
(2) Method 2: per mu: "strong micro denitrifying bacteria" 30 g + "desulfurized hydrogen composite bacteria" 100 ~ 200 g + brown sugar 3 ~ 5 kg; used to treat conventional nitrite exceeding the standard, use again every few days;
Sixth, the treatment method when encountering enteritis of the white stool
Table 6: Principle and method of strong micro-treatment of white stool enteritis of tutang shrimp
The main cause of shrimp white stool enteritis stealing death
Processing methods
(3) Strengthen the operation of sewage suction and sewage discharge with sewage discharge conditions, check the sewage collection capacity of ponds (sometimes the sewage collection function is insufficient, resulting in sewage empty discharge); if there is no sewage discharge condition, increase the oxygenation capacity, or invest oxygenation particles for a few days or oxidation to change the bottom;
2. Dirty and smelly silt (Vibrio exceeds the standard - the accumulation of putrefactive substances reaches qualitative change)
This is the focus.
(1) Every 3 to 5 days, sprinkle 100 g/mu of "arc cleaning and mud-changing pellets", a total of about 3 times; inhibit Vibrio and harmful bacteria in the silt;
(2) If vibrio silt exceeds the standard and is too dirty and smelly, it is directly treated with a potassium persulfate compound salt, or bromochrhydanine tablets, or chlorine dioxide effervescent tablets for 1-3 times, that is, first clear the field, and then replenish the bacteria; after a day with these two disinfectants, you can sprinkle "arc cleaning and mud pellets" for replenishment;
3. Intestinal flora disorders, vibrio intestinal exceeding the standard, intestinal mucosa detachment;
Lactic acid bacteria inhibit Vibrio, Clostridium butyrates repair the intestinal mucosa;
(1) Meal mix: add per kilogram of shrimp feed: "lactic acid butyric acid mixture treasure" 5 to 10 grams + strong micro aquatic glycosides 1 gram + water 200 grams, evenly stirred into the feed feeding, or fermentation for a few hours and then feeding the effect is better; continuous feeding for 5 days;
Precautions: After 5 days of continuous use of large doses, it can basically be relieved; then reduce the dosage to "lactic acid butyric acid mixing treasure" 2 grams + "strong micro aquatic glycosides" 0.5 grams; for prevention;
4. If the pond appears: high temperature - thick green algae - cyanobacteria - naked algae - ultra-high PH;
Use: deepening water color to reduce photosynthesis + improve water carbon-nitrogen ratio + decomposition of concentrated algae; three-in-one treatment;
(1) PH reduction: during the day with sodium humic acid 1 to 3 kg (shading to reduce photosynthetic intensity) + citric acid 5 kg / mu / time, once not 1 to 2 times, the method of citric acid is simple and direct, it is also a high carbon source;
(2) With Bacillus: activate "thick green blue bare algae" 500 g /mu + brown sugar 2 to 4 kg / mu + water 50 kg during the day; after soaking and activating for 1 to 12 hours, leave it until the evening to sprinkle;
(3) Freshwater aquaculture conditionally sprinkled with sea salt 5~15 kg/mu and VC to alleviate stress.
5. Hydrogen sulfide - salt - ammonia nitrogen exceeded the standard
It is also one of the factors that induce white stool
(1) Conventional nitrite and hydrogen sulfide exceed the standard: once every 3 days, use "strong micro-denitrification bacteria" 30 g + "hydrogen desulfide composite bacteria" 100 to 200 g + "fermented corn liquid" 10 to 20 kg per mu;
(2) Stubborn nitrite exceeding the standard treatment: use "strong micronitrine double decombine bacteria" 500 g / mu + "fermented corn liquid" 15 kg / mu; 1 time is not OK, after 3 days to use 1 time;
(1) The above products and "fermented corn liquid" are recommended to be used better in the evening;
(2) There is no "fermented corn liquid", you can use brown sugar 3 to 5 kg per mu (or molasses 5 to 10 kg) instead, the more carbon sources the more significant the effect, if there is sodium acetate trihydrate, you can use sodium acetate instead of half of the brown sugar, which is a highly efficient carbon source of denitrification desalination, these two carbon sources are matched, the desalination effect is the best, but sodium acetate can not be used for strain activation, just directly spilled into the pond;
6. If Vibrio aqueous body exceeds the standard: inhibited with Enterococcus lactic acid feces;
It is also one of the factors that induce white stools
(1) Method 1: use 250 g/mu + 3 kg brown sugar + 60 kg of water with "seedling rescue lactic acid bacteria phase", and splash it within 6 hours of activation; or inflatable activation for 12 to 18 hours;
(2) Method 2: Sprinkle 50 kg/mu with "lactic acid bacteria spreading liquid" (low cost and good effect)
Note: The above two methods are two choices, not referring to simultaneous use;
vii. Preparation methods attached to various fermentation and propagation solutions;
(1) A set of tanks is used to make "fermented corn liquid"
(In 2021, you can also directly purchase the "fermented carbon source" of Qiangwei, which is more professional and has better results):
The purpose is to provide the bacteriomatic nutrition required by the high lactic acid bacteriophasis in the water body, which is a must for shrimp culture in the high bacteriosynology, if the "fermented carbon fertilizer" is not used, the effect of using the bacteriological agent will be greatly reduced, because it is the grain and grass of the bacteriophasis in the water.
(1) The production formula of "fermented corn liquid": 1 pack of "strong micro aquatic carbon fertilizer nitrogen fertilizer fermentation agent" + 1 pack of "strong micro whole pool ecological conditioning bacteria" + 100 kg of corn flour + 500 kg of water + brown sugar (or glucose white sugar) 5 kg, summer fermentation 2 to 5 days, fermentation to ABOUT PH4, can be used, sealed in a cool place can be stored for a month to use;
Among them, corn flour can also be replaced with cassava flour, sweet potato flour, barley flour, sorghum flour, flour, rice or crushed rice (rice grains do not need to be crushed); it can also be replaced with 3 times the amount of fresh sweet potato pulp or tapioca pulp or potato pulp (when fermented with potato pulp, the water consumption is reduced accordingly, as long as the total amount of material for fermentation is consistent with the above formula); these are raw materials with high carbon-nitrogen ratio; these are raw materials with high carbon-nitrogen ratio;
Finally, fermented fruit and vegetable pulp, also uniformly classified into the category of "fermented corn liquid", and is a carbon fertilizer with a better effect rich in vitamins and fruit acids, such as pineapple, citrus, apple, mountain residue, carrot, cabbage pulp, broccoli, banana, grape... Such residual fruits and vegetables can be fermented after beating, the method is: 1 pack of "strong micro aquatic carbon fertilizer nitrogen fertilizer fermentation agent" + 1 pack of "strong micro whole pool ecological conditioning bacteria" + 600 kg of residual fruits and vegetables made of pulp + brown sugar 10 kg + salt 3 kg, stir evenly, summer sealed fermentation for 3 to 5 days, or PH is about 4, can be used, sealed can be stored for two months to use;
(2) A set of cans is used to make "lactic acid bacteria spreading liquid":
The purpose is to regularly supplement the water body lactic acid bacteria phase, of course, if you are troublesome, you can also not make, and directly use the "ammonia lowering water lactic acid bacteria phase" soaked water splash to replace; but the "lactic acid bacteria spreading liquid" made by yourself The cost of use is significantly lower;
(1) The production formula of "lactic acid bacteria expansion liquid": take the "strong micro-lactic acid bacteria expansion liquid to make bacteria" product 250 grams + 20 kg brown sugar + "strong micro-aquatic glycosides" 250 grams (or "strong micro-culture algae enzyme" 2 kg) + 300 kg of water, sealed fermentation culture for 2 to 3 days, you can use, usually sealed and stored, but it is best to use up within 20 days, the longest shelf life is recommended to be 30 days.
(3) This fermentation workshop can also ferment many things
The following introduces some strong micro-user feedback experience, and farmers with hearts can choose to make it
(1) "Fermented fish sauce" is made
1 pack of "strong micro aquatic carbon fertilizer nitrogen fertilizer fermentation agent" + 1 pack of "strong micro ammonia beautiful water lactic acid bacteria phase" + small trash fish made of pulp 100 ~ 200 kg + corn flour 100 kg + brown sugar 15 kg, and then stir evenly, and then stir while adding water to immerse the material, you can seal the fermentation (with a screw cap do not spin to death, so as not to explode), can be successfully fermented in just 20 days (referring to summer); and soon there is no odor, this fermentation is very fast Among them, small miscellaneous fish syrup can also be directly replaced by about 100 kg of fishmeal;
This kind of fish sauce that adds a large amount of energy feed to ferment together can not only cultivate algae, but also cultivate bacteria, which is an aquatic water transfer product that both cultivates algae and culture bacteria, and can even be used appropriately in the middle and late stages of shrimp farming and fish farming;
Pay attention to exhaust deflation, with a screw cap can be left in a circle not to spin to death, or with plastic film cover with rubber rope tied firmly, then do not use exhaust deflation;
First of all, "fermented fish sauce" can be used for shrimp mixing, and adding "fermented fish sauce" to about 10 kg per 100 kg of feed can significantly improve palatability, increase feed intake, increase growth rate, and improve immune stress resistance and improve health;
Another use skill: before the early spring or autumn shrimp fry, use "fermented fish sauce" 15 to 25 kg / mu for algae cultivation insect treatment, and then put shrimp fry, can significantly improve the survival rate and growth rate of shrimp fry, after the seedlings, you can also continue to supplement "fermented fish sauce", or shrimp fry stage use a simple "fermented egg duck feed" instead of shrimp powder, the effect is better and healthier, the intestine is thick;
(2) "Fermented egg duck feed" replaces shrimp milk powder
With 1 pack of "strong micro aquatic carbon fertilizer nitrogen fertilizer starter" + 1 pack of "strong micro ammonia beautiful water lactic acid bacteria phase" + 40 kg of egg duck feed + 150 kg of water + 7.5 kg of brown sugar, sealed fermentation for 4 to 5 days, shrimp fry will be fed on the second day, every 100,000 shrimp fry poured 1 ~ 2 kg / day, even water belt duck feed 1 ~ 2 kg / day;
(3) Preparation method of "fermented wheat bran or rice bran liquid fertilizer":
1 pack of "strong micro aquatic carbon fertilizer nitrogen fertilizer starter" + 1 pack of "strong micro whole pond ecological conditioning bacteria" + 75 kg of polished rice bran (or wheat bran) + 500 kg of water + brown sugar (or glucose white sugar) 5 kg, fermentation in the summer for 2 to 5 days, fermentation to about PH4, can be used, sealed in a cool place can be stored for a month to use up; smell extremely sour and wine; some odor after a long storage time is normal;
This "fermented wheat bran or rice bran liquid fertilizer" can be used for early spring low temperature fertilizer water, as well as late autumn low temperature fertilizer hydroponic algae; for ponds that are difficult to fertilize, it can promote algae cultivation;
(4) "Liquid fermented nitrogen fertilizer" production:
1 pack of strong micro soybean meal starter + 1 pack of strong micro-beautiful water hormone + 100 kg of soybean flour (or rape meal or vegetable cake powder, or cotton meal cottonseed cake powder, or soybean meal flour, or peanut cake powder) + 500 kg of water + corn flour 25 kg + brown sugar or glucose or white sugar 10 kg, summer fermentation 3 to 5 days, can be used;
Note: These cake meal raw materials are best beaten into powder; the fermentation liquid can be stored in a cool place for one month; after a long period of storage, it can produce a sour odor, which is a normal phenomenon, as long as the PH is lower than 4.5, it does not affect the use;
It can be used for pond fertilizer water for difficult to cultivate algae, or for insect cultivation; the amount of one-time use is about 5-10 kg/mu;
(5) "Solid fermented nitrogen fertilizer" production:
1 packet of strong micro soybean meal starter + 1 pack of "strong micro-beautiful water" + peanut bran (or other cake meal such as rapeseed cotton meal) 200 kg + corn flour 200 kg + water 300 kg, stir well, seal fermentation for more than 15 days and can be used; if you can add animal protein such as miscellaneous fish syrup (or blood meal plasma, or meat bone meal, or chicken intestine or visceral pulp, etc.) to ferment together in the above recipe; the effect of cultivating algae is better, and it has a better effect of cultivating zooplankton (rotifers, twigs, around the foot); " The advantage of "solid fermented nitrogen fertilizer" is that the shelf life is long, and it will not deteriorate after several years of sealing;
It can be used for pond fertilizer water for difficult to cultivate algae, or for insect cultivation; the amount of one time is about 5 kg/mu;
It can also be used as a mixture; the dosage is about 10% of the feed amount;
