Beware of physiological diseases of edible fungi
Wild mushroom: caused by high nitrogen, high moisture and high temperature of culture material. The prevention and cure method: reduce the nitrogen content of the culture material, and increase the pH value of the culture material to 8 Mel 9.
Green mold: due to low pH value, poor ventilation of material bag, high bag temperature leads to stuffy stack. Prevention and treatment methods: increase the pH value to 8mur9, strengthen micropores to increase oxygen to promote bacteria, and prevent high humidity from stacking.
Dead mushroom: shortly after budding, sometimes a large number of small mushroom buds atrophy, turn yellow and even die. This is mainly due to the high temperature of the palletizer bag, the heat in the process of mycelium metabolism can not be released quickly, resulting in "burning bacteria" dead mushrooms, or because the humidity is too low, the young mushrooms are dehydrated and withered, or they are drowned due to too much water spray. Prevention and control methods: sowing at the right time, adjusting the stacking temperature, increasing air humidity during mushroom emergence, paying attention to ventilation and ventilation during mushroom bud period, and mastering the amount of spraying water.
Rotten mushrooms: too much humidity in the mushroom shed, poor ventilation, too much yellow water in the material surface, which will cause Pleurotus ostreatus to rot. Prevention and control methods: strengthen the management, the temperature is controlled at 8mur20 ℃ and the humidity is controlled at 80mur95%. Once rotten mushrooms occur, 3% Lysol solution can be used to clean the rotten place or spray 1500 times agricultural lianmycin solution.

Technology of producing Edible Fungi from Distiller's grains
1. Fresh brewer's grains adjust ph 8-9 with lime, add 3% corn powder and appropriate amount of sawdust according to wet weight, and adjust about 65% of the culture material. 2. After weighing the dry white distiller's grains, add 15% corn powder, 4% lime powder and 130% water to build a pile for fermentation. 3. The effect of high yield can be obtained by inoculating bacteria with bag aerated material, two-stage full transformation cultivation by border soil cover film mushroom production method or conventional mushroom production management. In order to make it easy for mushroom farmers to master, this paper focuses on the high-yield methods of cultivating Pleurotus ostreatus with fresh distiller's grains:

Introduction of several improved varieties of edible fungi
Summer mushroom 93 mushroom high temperature type, mushroom temperature 2534 ℃. The mushroom is round, white, short stalk, thick and dense meat, not easy to browning and long shelf life, so it is an excellent strain suitable for cultivation in summer. Nangxiu No.1 mushroom is medium-low temperature type, the temperature of mushroom production is 5-25 ℃. The mushroom cover is brown, the mushroom meat and handle are white, the taste is delicious and the shelf life is long. Wide temperature, strong fruiting ability at low temperature, high yield and stress resistance. L-Dongxiang 03 medium temperature type of Lentinus edodes, the temperature of mushroom production is 825 ℃. Large fruiting body, thick mushroom cover, beautiful mushroom shape, quality
