Cultivation techniques of Flammulina velutipes: what are the environmental requirements of Flammulina velutipes?

What are the environmental requirements of Flammulina velutipes? There are no netizens who understand it to help introduce the environmental requirements for the growth of Flammulina velutipes in the farming network, which are listed below for netizens' reference. Temperature requirements for Flammulina velutipes growth: Flammulina velutipes in different growth stages, the temperature range of mycelium growth is 3: 34 ℃, the optimum temperature is about 23 ℃, the temperature required for fruiting body differentiation is 10: 15 ℃, the optimum temperature is 12: 13 ℃, the primordium can grow in the range of 10-20 ℃, more than 23 ℃, the formed primordium atrophied and disappeared. The temperature needed for the normal growth of fruiting body is 5: 20 ℃, and the optimum temperature is 8: 12 ℃. The short-term inhibition treatment of cold air at 4 ℃ after fruiting body can make Flammulina velutipes neat and round. Humidity requirements for the growth of Flammulina velutipes: during the mycelium growth stage, the water content of the culture material is required to be 60%-68%. Practice has proved that according to the different texture of the culture material, properly increasing the water content of the culture material can play a certain role in increasing production. If the moisture content of the culture material is less than 50%, the mycelium growth is sparse and the structure is not good; if the moisture content is higher than 75%, the ventilation is poor, and the mycelium growth is slow or stops growing. The optimum water content of the culture material for fruiting body formation is 65%, and less than 50% fruiting body will not be formed. During primordium differentiation, the air relative humidity is maintained at 80%-85%; at the fruiting body development stage, higher air relative humidity is required. In addition to relying on its own moisture to meet the growth and development of the mushroom body, the air relative humidity should be increased to 85%-95%. The air requirement for the growth of Flammulina velutipes: Flammulina velutipes is an aerobic fungus, and it must have sufficient oxygen supply to grow normally, so the mycelium growth stage and fruiting body development stage need enough oxygen, otherwise, the growth of mushroom is slow, the stalk is slender, and does not form a cap. The fruiting body of Flammulina velutipes is very sensitive to the concentration of carbon dioxide in the air. When the content of carbon dioxide exceeds 1%, it inhibits the development of the cap, and when it exceeds 5%, it cannot form a fruiting body. Light requirements for the growth of Flammulina velutipes: Flammulina velutipes is a light-weary fungus, the mycelium can grow normally in the dark, and the primordium can be formed in the complete dark. In the growth stage of fruiting body, a certain amount of scattered light can promote the formation of fruiting body. Requirements of acidity and basicity (PH value) for the growth of Flammulina velutipes: Flammulina velutipes needs weakly acidic medium, which can grow normally in the range of pH3~8.4. In the mycelium growth stage, the optimum pH of the culture material is 4: 7. In a certain range of pH, the alkali of the culture material will delay the occurrence of the fruiting body, and the slightly acidic culture material will exuberant mycelium growth. The fruiting body produced the most and fastest during pH5~6. When the pH in the culture medium was lower than 3 or higher than 8, the mycelium stopped growing or no fruiting body occurred.
