Prepare nutrients before planting Flammulina velutipes, inoculate after mixing, and do a good job of sterilization, control the temperature and humidity, and promote mushroom production. 1, nutritional preparation. Because Flammulina velutipes is developed from a mycelium, we need to prepare nutrients for cultivating this mycelium before planting. Usually, we mainly use cottonseed hull, and then add some materials such as wheat bran, gypsum, sawdust and corncob, and then pile these materials on the sterilized ground, add some water and stir them evenly, at least three times a day, and then charge them three days later. 2. Inoculation management. First of all, we need to sterilize the packaged nutrients at high temperature or high pressure, then put the nutrients into the inoculation room, spread the nutrients evenly on the inoculation bed, usually according to the thickness of five to eight centimeters, then cool the nutrients, preferably at about 25 degrees, and finally inoculate the strains evenly into the culture medium for culture. In the process of inoculation, special attention should be paid to the disinfection of inoculation personnel and all instruments, so as not to affect the success rate of Flammulina velutipes inoculation. 3. Disinfection management. The most important thing in sterilization management is the management of temperature, humidity, air permeability and other fungi in sterilization room. First of all, we need to control the indoor temperature at about 20 to 25 degrees, and then with the growth of mycelium, the indoor temperature will become higher and the temperature will drop by two or three degrees. Generally, it takes about a month for bacteria to grow completely, so at this stage, we need to clean up other strains in food so as not to affect the growth of lily hyphae. 4. Mushroom management. Mushroom management is actually that the mycelium has basically developed, and then the entity of the mycelium can be seen, so it is necessary to scrape off the older strains on the surface, so as to promote the growth of the strains. Secondly, to reduce the indoor temperature here, the humidity in the air should reach at least 9 12%. At the same time, we must keep indoor air circulation, so that the Flammulina velutipes will be tender and taste better. 5, timely harvesting of Flammulina velutipes is easy to get old, so it is necessary to harvest mature Flammulina velutipes in time, usually when Flammulina velutipes grow to 12 to 15 cm. When harvesting, gently hold the handle of Flammulina velutipes, then slowly shake it and pull it out from the left, and then carry out mushroom management and mushroom management in the same way, so as to quickly enter the second batch of harvesting.
