The new cultivation method of Flammulina velutipes has high benefit.

At present, the conventional cultivation method of Flammulina velutipes, which is widely used in various places, although it can harvest 3 crops a year, the highest bioconversion rate of culture material can only reach 100%, each growth period is as long as 95 days, and there are only 3 cultivation cycles a year, and the third stubble mushroom stalk is short and thick, easy to open the canopy, and the commodity quality is poor.

The new cultivation technology of disposable culture material prepared according to the growth characteristics of Flammulina velutipes here, not only the biological conversion rate is as high as 193%, the cultivation period is shortened by 40 days, but also the number of Flammulina velutipes increases, the stalk increases, and the economic benefit is increased by about 80%. The comparative advantage is very obvious. The main technical points are as follows:

1. Self-made 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 then mixed well with water according to the feed-water ratio of 1 ∶ 1.3 to form the culture material.

2. Filler disinfection. When the culture material is put into a wide-mouth bottle (bag), the packing must be loose and tight in order to effectively avoid the phenomenon of mushroom emergence in the later stage of the bottle (bag). After filling, fasten the mouth of the bottle (bag) firmly, put it into a normal temperature pot and cook at 100℃ for 8-10 hours. It can also be sterilized with a pressure cooker for 90 minutes under 1.5kg / square centimeter pressure.

3. Suitable temperature cultivation. After the high temperature (high pressure) disinfection and thorough cooling, 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 in the range of 22-26 ℃, and it is strictly forbidden to prolong the culture period at low temperature, so as not to affect the yield and quality of mushrooms before the mycelium is full.

4. Careful management. 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. When the buds are formed, it is necessary to do a good job in regeneration management to promote the increase of mushroom bud density, and then bag or cover the newspaper to form a high concentration of carbon dioxide microclimate in the bottle (bag), which is very beneficial to the growth of Flammulina velutipes.

When growing to 4-5 cm 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 ℃, and the cultivation site should be covered with straw curtain or black plastic sheet. the light intensity should be blurred by normal vision. Mushrooms can be harvested when they grow to 15-20 cm high.
