Prevention and control of dead mushroom
Cause of 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. The oxygen in the mushroom room is insufficient, the concentration of carbon dioxide is too high, and the heat generated in the metabolic process can not be released quickly, which will cause the young mushrooms to die in batches due to insufficient oxygen supply or high temperature.
(5) Drug damage. If the number of spraying is too much and the dosage is too large, the young mushrooms will die due to drug damage.
(6) Mechanical injury. Mushroom harvesting or other management operations are careless, resulting in injury and death of young mushrooms.
Prevention and cure method
(1) arrange the inoculation time to avoid mushroom in high temperature season.
(2) in the stage of soil covering and water transfer, the mycelium should be prevented from growing out of the soil surface and the mushroom position should be depressed so as to avoid overdense mushroom production.
(3) pay attention to the cooling of mushroom room and improve the ventilation condition.
(4) the door and window of mushroom house should be opened by spraying water during high temperature, and bamboo stick should be used to seep through the hole when the material surface is stagnant.
(5) do not overdose when controlling diseases, pests and miscellaneous bacteria, and avoid using drugs during mushroom production.

Mushroom soil fertilization can increase yield.
In order to increase the yield of mushrooms, fertilizer must be applied properly. According to the practice of mushroom farmers in many places over the past few years, it has been proved that the following nine soil methods of fertilization will have a good effect on increasing production. Mushroom soup. Wash the mushroom feet and chopped mushrooms in harvesting and processing, cut into thin slices, add 1.5 kg of water per kilogram of material, boil for 15 minutes, dilute the filtrate and water to 10 Mel 15 kg, spray the mushroom bed 30 Mel 40 square meters. Use during peak mushroom production

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
