2. When the temperature is lower than 2℃, it will grow slowly; when it is higher than 3℃, it will age and turn yellow; when it is higher than 37℃, it will stop growing.
3. The temperature requirement of fruiting body is not high, and it can normally produce mushrooms at 1-32℃.
4. The water content of mycelium growth is required to be 65%, while the primordium is formed until the fruiting body is mature, and the relative humidity of air at this time is 85-9%.
2. Air illumination 1. Good ventilation conditions are needed in the mycelium stage and fruiting body stage. If the concentration of carbon dioxide in the air is too high, it is easy to form small mushroom caps and deformed mushrooms.
2. No light is needed in the mycelium stage, and 2-2, lux light is appropriate in the fruiting body stage. Too dark and too strong light are not good.
3. PH value and nutrition 1. It is advisable to adjust the PH value of the culture medium with 3-5% quicklime water, and the PH value is 7.2-7.5.
2. Its growth and development need carbon, nitrogen and various mineral nutrients, and it can only live on existing organic substances.
3. During its growth and development, carbon, nitrogen, minerals and auxin can be obtained from the cultivation materials.
