The cause of mushroom death: the temperature of ① at the end of autumn was too high (more than 23 ℃), and the temperature rose too high and too fast during the spring emergence period (21 ℃ for several days in a row), resulting in the shrinkage and death of young mushroom seedlings due to lack of nutrition. ② mushroom room is poorly ventilated, O2 is insufficient, the concentration of co2 is too high, and the heat generated by metabolism can not be released quickly, which will make the young mushroom seedlings die in batches due to insufficient oxygen supply or high temperature. three

Dead mushroom refers to the phenomenon that the small mushroom on the mushroom bed shrinks, yellowes and dies. Mushroom wilt appears in pieces or in batches, which will seriously affect the yield.

1. The cause of mushroom death: the temperature of ① at the end of autumn was too high (more than 23 ℃), and the temperature rose too high and too fast during the spring emergence period (21 ℃ for several days in a row), resulting in the shrinkage and death of young mushroom seedlings due to lack of nutrition. ② mushroom room is poorly ventilated, O2 is insufficient, the concentration of co2 is too high, and the heat generated by metabolism can not be released quickly, which will make the young mushroom seedlings die in batches due to insufficient oxygen supply or high temperature. After ③ mulching, the mycelium grew too fast before mushroom emergence, so that the mushroom seedlings were too dense, the nutrition supply was insufficient, and some of the mushroom seedlings died. The ④ temperature is above 22 ℃, the relative humidity is above 95%, or the doors and windows are closed after spraying water, the mycelium surface is waterlogged, and the young mushroom seedlings suffocate to death. ⑤ management operation is careless, resulting in mechanical damage resulting in dead mushrooms. There were many times and large amount of ⑥ spraying, and the mushroom seedlings died due to drug damage.

2. Control methods: ① arranges the inoculation time according to the local climatic conditions to avoid mushroom production in the high temperature season. ② pays attention to the cooling of the mushroom room to prevent the attack of high temperature. In the stage of soil mulching and water transfer, ③ should prevent the mycelium from growing out of the soil surface, lower the mushroom position, and avoid overdense mushroom production. In the period of ④ high temperature, the doors and windows should be opened, and the stagnant water in the material layer should be pierced with bamboo sticks to improve the ventilation condition. When using ⑤ to control diseases, insects and miscellaneous bacteria, do not use too much medicine, and avoid using drugs during mushroom production.
