Causes and control of mycelial atrophy of volvariella volvacea
1. The use of inferior bacteria: the age is too long or too short, the strain degenerates, the mycelium is weak, the stress resistance is poor, or the strain is stored in an environment where the temperature is too low or too high for a long time, there will be the phenomenon of non-germination and mycelium shrinkage after sowing. Prevention and treatment: select the right age, high-quality bacteria, and ensure that the temperature in the culture process is not too low. two。 Improper control of culture material temperature: when the air temperature is high, the culture material is thick, and the heat preservation performance of the mushroom room is good, the temperature in the culture material exceeds 42 ℃ for a long time after sowing, which will lead to mycelium shrinkage, death and burning bacteria.

Prevention and Control techniques of Mushroom death Disease
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. three

Prevention and control of dead mushroom
The reason for the death of mushroom (1) the growth of young mushroom is weak. After the mushroom bed is covered with soil, the mycelium grows too fast, the mushroom position is too high, and the young mushroom is too dense, which leads to the death of some young mushrooms with insufficient nutrition supply. (2) too high temperature. When the temperature is above 21 ℃ for several days during mushroom emergence, the young mushrooms will shrink and die due to heat injury. (3) excessive humidity. The relative humidity of the mushroom room is more than 95% at high temperature. if the doors and windows are closed after spraying water at this time, and the surface of the mushroom bed is waterlogged, the young mushrooms will suffocate to death. (4) poor ventilation. Oxygen in mushroom room
