< h1 class="pgc-h-arrow-right" data-track="35" > the choice of culture medium</h1>
There are many raw materials used to cultivate oyster mushrooms, such as cotton shells, sawdust, corn cobs, straw, wheat grass, straw, leaves, sweet potato vines, etc. can be used to cultivate oyster mushrooms. However, among them, the cottonseed shell is the best, and each kilogram of cottonseed shell can produce more than 3 kilograms of fresh mushrooms. The cottonseed hull used to cultivate oyster mushrooms must be fresh, dry and mildew-free, and the old cottonseed hulls of previous years are not recommended.
< h1 class="pgc-h-arrow-right" data-track="34" > venue selection</h1>
Oyster mushrooms can be grown in open air, orchards, woodlands, unused houses, plastic greenhouses, basements, etc. as long as they are well drained and ventilated, and there is no source of pollution.
The new site only needs to be cleaned up and wiped with lime water, and the site where edible mushrooms have been planted needs to be disinfected, fumigated with sulfur or diluted with 1000 times of potassium permanganate solution, sprayed on the room, and then sealed for about 12 hours.
<h1 class="pgc-h-arrow-right" data-track="37" > preparation of culture medium</h1>
Cottonseed husks are added as the main ingredient, wheat bran, calcium superphosphate, gypsum powder, and lime. The specific proportions are: 90% of cottonseed hull, 5% of wheat bran, 1% of calcium superphosphate, 3% of lime, 1% of gypsum. If it is a raw material cultivation, carbendazim should be added for sterilization, and clinker does not have to be added.
<h1 class="pgc-h-arrow-right" data-track="33" > raw material cultivation</h1>
The raw material cultivation operation is simple, saving labor and time and cost, and there is less nutrient loss in the culture material without high temperature cooking, and the planting yield is high, which is the more commonly used planting method at present.
The prepared main ingredients and ingredients are placed in a clean open space and stirred evenly, and then mixed with water according to the ratio of 1:1.2~1:1.3 of the material water, and adjusted to a moisture content of about 60% (it is appropriate to squeeze the mixed culture material by hand, and it is appropriate when there is water oozing between the fingers and not dripping down), the PH value is 7.5 ~ 8.
<h1 class="pgc-h-arrow-right" data-track="12" > fermentation</h1>
The cultivation of raw materials must be fermented. The evenly stirred culture medium is piled into a circular pile of 50 kg per square meter, if the amount of culture material is large, it can be stacked into a long shaped pile, stacked well compacted, and inserted a wooden stick into the bottom to open the air hole. The fermentation is then covered with a plastic film. After 1 day, check that when the material temperature rises to about 70 degrees, the pile should be turned over to avoid excessive temperature. Generally after about 5 days, it will ferment well.
<h1 class="pgc-h-arrow-right" data-track="27" > inoculation</h1>
Using the barrel bag planting method, the plastic cylinder bag specification is 22 to 25 cm wide and about 40 to 50 cm long. When loading, first tie one end of the plastic cylinder bag, pack a layer of bacteria and then pack a layer of material, press it tightly while loading, and then pack 3 layers of material in turn and seal the material with bacteria and tie the mouth of the bag. One bag of inoculation material is 3 layers of culture material, 4 layers of bacteria, the amount of two-headed bacteria is more, and the amount of intermediate bacteria is less.
<h1 class="pgc-h-arrow-right" data-track="28" > germ management</h1>
After inoculation, the bag is stacked indoors or in the greenhouse to germinate, if the temperature is lower than 10 ° C in winter and spring, you can stack 3 to 5 layers, if the temperature is high, the stack can be placed in 2 layers. No light is required during the entire germination period, so the germ chamber is shaded. Generally under the conditions of suitable temperature, humidity and good ventilation, the hyphae can be full of culture medium after 20 to 30 days.
<h1 class="pgc-h-arrow-right" data-track="29" > mushroom management</h1>
After the hyphae are full, when a grape-like fruiting body primordium appears on the surface of the culture material, it is necessary to carry out artificial mushrooms, at which time the light can be increased, ventilation and ventilation can be increased, the relative humidity of the air can be increased, the indoor temperature difference is increased by 10 ° C to 20 ° C, sprayed to the ground and wall, and the relative humidity of the air is increased to 90%.
<h1 class="pgc-h-arrow-right" data-track="30" > harvested</h1>
Timely harvesting is a good way to ensure the quality and yield of oyster mushrooms, which can be harvested when they begin to change from dark to shallow and the edges of the cap have not yet been fully unfolded. After harvesting, it is necessary to clean up the mushroom feet and dead mushrooms on the surface in time to prevent them from rotting, and then spray water to moisturize after 2 days of stopping the water to stimulate the budding out of the mushrooms. Generally, after 10 to 15 days, a second stubble mushroom can be produced, and 4 to 6 stubble mushrooms can be harvested.
