Recently, a farmer encountered a very headache: because his family's farmland is relatively low-lying, he will grow a large number of reeds in his field, which seriously affects the growth of crops in the field. But these reeds in the field are very stubborn like "undead little strong", they grow and reproduce fast and do not kill, do not remove the roots, often a long is a large pile, a long is a large piece. According to this peasant friend: cutting with a sickle, burning with fire, and beating herbicides do not work, can not remove the roots, for these reeds, he is trying to "control every year, every year, every year because of his headache"!
Today, the agricultural technology basket will tell you how to completely and effectively control the reeds growing in the field!
First, reeds are stubborn, difficult to remove and exploit malignant weeds
(1) Reed is a vicious weed with great reproductive and diffusion ability.
Reeds have a particularly wide range of growth and distribution, very strong environmental adaptability, particularly strong growth ability, particularly strong root reproductive ability, and particularly fast propagation and diffusion of weeds of perennial grasses, which are very difficult to control, and the weeds are rooted and grown in a certain place (especially in the rainy season and low-lying wet land), If the control and cleaning is not timely, it will breed wildly, grow densely upright, and the rhizomes will be staggered into pieces. Note that reeds spread mainly by propagating at close ranges at the rhizome site, but can also spread over long distances by seeds drifting with the wind.
(2) Reed is a vicious weed that prefers high temperature and high humidity.
It is not only hardy and drought-resistant to high temperatures, but also especially likes to take root and grow in places close to water sources and moist soil, paddy fields, dry land can grow, corn fields, rice fields, wheat fields, orchards, vegetable fields, cotton fields, etc., will often see the figure of reeds growing thick and straight. Especially in the summer and autumn high temperature and rainy and wet season, in the low-lying terrain is easy to accumulate water, close to the water source of lakes and rivers, close to ponds and ditches, etc., it is very conducive to the vigorous growth and rapid reproduction of reeds.
(3) Reed is a vicious weed that is difficult to kill/control/difficult to remove.
First, reeds are plants that can grow and survive for many years. After the leaves of the aboveground stalks wither in winter, the underground roots will grow from budding again in the spring of the following year;
Second, the reeds have strong vitality, growth rate, and reproductive ability. Drought and flood environment does not affect its survival, high temperature and low temperature conditions will not completely die, its rhizome is very developed, rhizome reproduction is particularly fast, and each rhizome can grow into a separate reed, in a high temperature and humid environment, a rhizome can reproduce a lot of new rhizomes, so reeds are easy to quickly connect with groups of trees, groups of pieces;
Third, reeds are highly self-protective and resistant. The stem and leaf surface of the reed have a thick and hard waxy layer, and the leaves are narrow and long, and it is difficult to attach the liquid, so it is difficult to achieve obvious killing effect when spraying, on the one hand, the resistance and drainage of the reed are very strong, and the ordinary herbicide is basically ineffective after spraying; On the other hand, the smooth and thick stalk leaves of reeds are difficult to adhere, difficult to penetrate, and difficult to absorb the medicinal liquid, and this non-sticking, impermeable plant characteristics make it difficult to kill it by conventional herbicides; On the other hand, it has the characteristics of suspended dead plants, when the stem and leaves are physically damaged or damaged by drugs, they will quickly turn yellow and fall off for "suspended animation" self-protection (the plant secretes excision acid substances to shed the leaves, so that the liquid cannot penetrate and conduct to the fiber tubes of the stem and the underground rhizome site and completely kill it), but the underground root system is still good to continue to re-sprout long leaves from the rhizome site or the axillary bud site;
Fourth, the root system of reeds has developed and strong reproductive ability. The root system of reeds is difficult to be completely killed, the root is difficult to remove the root, that is, its root system is very developed, the root system reproductive ability is too strong, the root system of the reed can grow horizontally or vertically underground (growing in four directions up and down, left and right), its root system is crisscrossed and densely networked underground, and each root stem node can grow into a tree alone (it is very difficult to pull the root of the reed), even if we kill all its aboveground stems and leaves by artificial cutting, chemical spraying and other methods. This does not affect its continued large-scale rapid reproduction and growth at all, so if the reed is not completely killed by its rhizome, it cannot be completely and completely killed, and there is a poem that describes the growth ability of the reed very appropriately - "the wildfire burns endlessly, and the spring wind blows again."
(4) Reed is a plant with great use value and wide range.
The agricultural technology basket summarized the four major disadvantages and harms of reeds for everyone above, but the advantages and values of reeds cannot be denied.
From top to bottom: First, the spikes of reed flowers on top of the reeds can be used to tie brooms and fill pillows; Second, the stem in the middle of the reed can be used to weave grass mats and make reed flutes, and the stems with high fiber content can also be used to produce paper and artificial fibers; Third, the rhizome in the lower part of the reed can be medicated, and after decoction, it can play a certain role in clearing heat, diuresis and hemostasis.
Second, the harm of reeds and prevention and control skills
The harm of reeds is mainly reflected in the following two points: (1) The underground rhizomes of reeds are staggered and developed, which will not only compete with crops for water and fertilizer resources, but also lead to poor crop growth and development, and will also seize a large number of underground soil resources for crop growth. (2) The stems and leaves on the reed ground grow vigorously and densely, and the stems are upright and robust, which will not only increase the incidence of field diseases and insect pests, but also cause poor ventilation and lighting environment of field crops. (3) The reproduction and diffusion ability of reeds is too strong, and once invaded into the farmland, it is easy to breed into groups.
The following focuses on the comprehensive cure method of reeds:
(1) The method of making a contribution is not pleasing - the knife cutting method and the root digging method
(1) Knife cutting root method: that is, in the "three volt days" with the highest temperature and the highest humidity in the year (between the summer festivals everywhere), use a sickle to cut from the roots of the reeds (cut 2-3 times in succession according to time), the purpose of this is to make the roots of the reeds rot in the wet and hot environment, but this method is more suitable for use in paddy fields (broken roots are more likely to rot in water). This method is not easy to remove the root, and it is easy to rebound in the second year, so it is a thankless practice and is not recommended for everyone.
(2) Deep digging root method: that is, when the land is intermittently prepared, the reeds are dug out of the soil by manual or mechanical digging out, for example, a few trees can be combined with the deep ploughing of the land to manually dig the roots of the reeds one by one, for example, when the reed area is relatively large, it can be combined with the use of large machinery such as bulldozers to pick the roots in a large area when the land is deeply turned. Although this method is easy to root, it is labor-intensive and time-consuming and troublesome, so it is generally not recommended for everyone to use.
(2) Time-consuming and labor-intensive manual eradication method - injection method and touch coating method
Both the injection method and the touch method need to be achieved by using a herbicide, although these two methods require a lot of labor and time (more suitable for the use of small reed growth or small growth area), but these two methods can play a good role in completely killing the reed root system and eradicating the reed.
(1) Liquid injection reed core method: After the reed spring from April to June into the vigorous growth period, when the height of the reed stem grows to about 30-50 cm high and there is no large number of roots, first cut off the upper part of the reed, and then use a graduated needle to glyphosate liquid (10% glyphosate when the use of medicine and water ratio of 1:1, 30% glyphosate use when the medicine 200 ml + water 300 ml, Can be used 500 ml of mineral water bottle with pharmaceutical liquid) injected into the reed stem core (in accordance with the dosage method of 1 reed core injection of 5 ml liquid), the general reed core will be yellowed after 1-2 days after the injection of the liquid, 3-5 days after the whole tree will be killed, if there are still remnants of the reeds after 7-10 days have not died, you can use the same method to inject the liquid again, generally continuous injection of the liquid 2-3 times can completely kill the reeds in the ground.
(2) Liquid application method: Also in the reed 4-6 months of vigorous growth period and the plant height of about 30-50 cm, first according to the amount of glyphosate liquid used in article (1) to prepare the liquid, and then first bring a waterproof and anti-medicated rubber gloves on the hand, the rubber gloves are covered with a pair of absorbent cotton gloves (or prepare a cotton cloth), and then use the chemical solution to dip the wet cotton gloves (or cotton cloth), and then use the cotton gloves (or cotton) with glyphosate liquid to repeatedly touch and wipe the tip of the reeds. This can also have the effect of completely killing the entire reed with roots and stems and leaves. If you think it is inconvenient to use cotton gloves or cotton cloth, you can also use cotton swabs and other cotton swabs to dip the liquid such as applying reed tips.
In addition to the liquid to apply the young reed tip (the tip of the reed absorbs the liquid is good), you can also use the liquid directly to apply the upper part of the reed stalk and leaves (the liquid can also penetrate into the reed through the stem and leaves, and conduct to the root of the reed), in addition to the use of glyphosate (see green on the killing type of non-selective, extinct herbicide), you can also use high-efficiency fluoropyridoxine (this medicine is registered as a drug to control reeds, belongs to the selective herbicide that is not prone to drug harm) or refined pyridoxine fluoroherace, Phosphonium glufolin, cyanofloxate, quinoquinol and other herbicides that can effectively kill reeds.
(3) Saving time and saving time and killing methods for killing drugs - chemical herbicide control methods
Many farmers say: I have used the method of spraying medicine to control reeds, and playing herbicides on the reeds cannot kill the reeds, and cannot eradicate the reeds!
In fact, the reed belongs to the vitality is very tenacious and resistant to self-protection of the vicious weed, everyone in the use of herbicides to control reeds, if you do not choose the right herbicide or did not seize the best time to spray or did not use systemic conductive drugs when spraying, there is no field silicone / orange peel essential oils of the synergist, then you can not kill after spraying, can not get rid of the reed root is very normal, and even improper use of drugs when spraying will also cause crop herbicide damage (such as the use of nicosulfuron is easy to cause corn drug damage, The use of glyphosate is easy to cause drug damage to various crops, etc.).
Therefore, to control reeds, on the one hand, we must choose the fierce medicine on the road, on the other hand, we must master the method of scientific use, otherwise it will not only kill the reeds, but also easily cause crop damage, these two points are very important to everyone, we must keep in mind!
From the perspective of prevention and control effect, herbicides that can completely kill reeds and completely remove roots mainly include high-efficiency flupiroxamyl (registered and registered as a herbicide specifically used to control reeds), glyphosate (see green herbicide, herbicide also kill crops, use cautiously), nitramine and wesherding (compounded by nitrosulfonone + nicosulfuron + indigodine, improper use is easy to cause corn medicinal harm) and refined pyridoxine, ammonium glufolin, cyanofluroxate, fine quinopyridine, chlorfluoropyridyl ester and other fierce drugs.
From the perspective of drug selection and use, if it is an ordinary farmland or a plot of planting seedlings with short and large leaves (such as soybeans, cotton, melons, fruits and vegetables, etc.), the agricultural technology small back basket recommends that you directly use 60-80 ml of 10.8% high-efficiency flupiramide or 50-60 ml of 35% fine pyriforohelin at the reed 4-6 leaf stage or plant height of 30-50 cm (the best drug killing period) to spray the upper stems and leaves of the reed for complete extermination; If it is a wasteland where a large number of reeds are grown, outside the field or on the side of the road or next to the ditch where the reeds grow, perennial reeds are difficult to control, tall crops, and plots with large gaps in the field ridge, you can use 50 ml of 10.8% high-efficiency flupiramide + 250 ml of 30% glyphosate (200 ml of 41% glyphosate) + 30 kg (a barrel) of water per mu for spraying, and the effect of this formula will be more complete and significant, However, it is important to note that glyphosate spraying on crops can cause crop damage or directly kill crop seedlings.
In addition, we can also use refined quinoquinol + acetoxaline + dimerpentyl, high-efficiency fluoropyridoxine + glyphosate isopropylamine salt or drip glyphosate, high-efficiency fluoropyridoline + oxysalone, cyanofluorolin + dichloroquinoline acid, glyphosate + acetochloramine + silicone, nilfonylone + nicosulfuron + weedazin (corn seedlings can not be used until the 3-5 leaf stage, and glutinous corn sweet corn can not use this formula) and other formulas, these formulas even with roots to completely kill reeds The effect is also very significant, Basically, it can achieve the effect of medicine to the death of reeds.
Note:
(1) The prevention and control of reeds must use strong drugs, but when using strong drugs (especially when using glyphosate, etc., it is easy to kill crops or cause crop drugs to harm strong drugs), we must be cautious, if you feel that you do not have the confidence to use safe drugs, you can use the use of high-efficiency fluoropyridoxine, fine pyridoxine, etc. These are both effective and relatively safe herbicides to prevent the improper use of drugs to kill the crops and reeds in the field together.
(2) When the drug is used to prevent and treat reeds, it is necessary to use sufficient water and hit all through, if you want to improve the effect of the drug to kill the reeds, you can add a small amount of silicone, orange peel essential oil and other drug synergists according to the need to dispense the drug (can improve the adhesion, ductility and permeability of the liquid).
(3) When the drug is used to control reeds, if the reeds are completely dead after the first few days, there is no need to hit the second time, if the leaves are yellow and do not die after the first beat, then it may as well spray it again to completely kill the reeds.
(4) When drug control reeds, if you accidentally cause crop damage, then you can immediately use gibberellin, amine fresh ester compound amino acids, glucose, urea water, etc. foliar spraying, in order to reduce the efficacy of the drug to alleviate the drug damage, stimulate crop growth and reduce the drug damage.
Finally, I would like to add a sentence to you: the right medicine is selected for the prevention and control of reeds, and the use of strong medicine, but the prevention and control of reeds must be used scientifically and rationally, because any improper use of herbicides is easy to cause crop medicine to harm yellow leaves or cause crops to be killed by drugs.
