1. The cultivation of Flammulina velutipes begins with the development of mycelium. Before planting, the culture materials should be prepared first. The culture material takes cottonseed hull as the main raw material, adding appropriate amount of wheat bran, gypsum, sawdust, corncob and other materials, adding clear water, and continuously stirring for three days to ensure that the culture material is fresh, clean and mildew-free. Put the selected bacteria into a special bag, sterilize it under high pressure and spray a small amount of potassium permanganate solution.

2. Put the inoculated culture material into the inoculation room to wait for inoculation, spread the nutrients evenly on the inoculation bed for 5-8 cm, cool after spreading, and keep the temperature at about 25℃. Uniformly putting the strains into the culture medium for culture, and covering with a transparent film. Pay attention to the whole disinfection work. After inoculation, the temperature, humidity, light and ventilation should be well managed, and the strains in food should be removed during spawning.

Third, mushroom management In the process of mushroom cultivation, the indoor temperature should be reduced and controlled between 10 ~ 15℃. When the stem is 2 cm long, the humidity should be kept at about 90%, and when it is 10 cm long, the water spraying should be controlled in time to keep the air humidity at about 80%-85%. 2-3 weeks before fruiting, keep indoor air circulation.

Fourth, timely harvesting Flammulina velutipes should be harvested in time when it is mature. In general, it can be harvested when it grows to 12- 15 cm.
