Mushroom dead mushroom is a mushroom mushroom bed shrinking, yellowing, death phenomenon, into pieces or batches of mushrooms withered, will seriously affect the yield.
One, dead mushroom reason
1. The temperature in late autumn is too high (more than 23°C), and the temperature rises during the mushrooming period in spring (the temperature is 21°C for several consecutive days), causing the mushroom seedlings to die due to lack of nutrition and atrophy.
2, mushroom house poor ventilation, lack of oxygen, carbon dioxide concentration is too high, the heat generated in the metabolic process can not be distributed quickly, will make small mushroom seedlings due to lack of oxygen supply or high temperature death batch.
3, after the casing soil before the mushroom grows too fast mycelium, mushrooming parts are too high, the formation of mushroom seedlings too dense, lack of nutrient supply, and some of the mushrooms died.
4. The temperature is above 22°C and the relative humidity is above 95%. After spraying the water, the doors and windows are closed, the surface of the mycelia is stained with water, and the small mushroom suffocates.
5, mushroom and other management operations are careless, resulting in mechanical damage caused by dead mushrooms.
6, spraying a large number of large quantities, mushroom seedlings died of phytotoxicity.
Second, prevention methods
1. According to the local climatic conditions, arrange the inoculation time and avoid the mushrooming in the hot season.
2, pay attention to mushroom house cooling, to prevent high temperature attacks.
3, in the cover soil transfer stage to prevent the mycelium grow out of the soil surface, reduce the mushroom position, to avoid excessive density.
4, the high temperature time to spray the water to open the doors and windows, the material layer of water with bamboo stick holes, improve ventilation.
5, when preventing and curing diseases and insects, do not use excessive amounts of drugs and avoid using drugs during fruiting.
