Flammulina velutipes: the new cultivation method has high benefit.

Homemade culture material. 84% cottonseed hull, 14% wheat bran, 1% gypsum, 0.2% potassium dihydrogen phosphate, 0.25% magnesium sulfate and 0.55% carbendazim were mixed evenly and mixed well with water according to the feed-water ratio of 1 ∶ 1.3 to form the culture material. Stuffing and disinfection. When the culture material is put into the wide-mouth bottle bag, the packing must be loose and tight in order to effectively avoid the phenomenon of mushrooms all over the bottle bag in the later stage. After filling, seal the mouth of the bottle bag tightly, put it into a normal temperature pot and disinfect it, and cook at 100 ℃ for 8 hours for 10 hours. Suitable temperature cultivation. After cooling thoroughly, under the alcohol lamp flame in the inoculation room or inoculation box, the inoculation shovel was used to dig out the strain block from the strain bottle and move it into the cultivation bottle bag, and then put it into the culture room for mycelium culture. The temperature of the culture room must be controlled at 22 ℃ ~ 26 ℃. It is strictly forbidden to prolong the culture period at low temperature in order to avoid mushroom emergence before the mycelium is full and affect the yield and quality. Carefully managed. After the mycelium grows full, it should be moved into the mushroom farm in time, open the bottle bag to scratch the bacteria and stimulate the mushroom production. When the buds are formed, it is necessary to do a good job in regeneration management to increase the density of mushroom buds, and then cover the bag or cover the newspaper to form a high concentration of carbon dioxide microclimate in the bottle bag, which is conducive to the growth of Flammulina velutipes. When the mushroom grows to 4cm high, special attention should be paid to water management, the humidity of the cultivation site should be kept at 80%-90%, the temperature should be kept at 8 ℃-14 ℃, and the cultivation site should be covered with straw curtain or black plastic (11255,-30.00,-0.27%). The light intensity should be blurred with normal vision. Mushrooms can be harvested when they grow to 15cm or 20cm high.
