In the production of Agaricus bisporus, due to the environmental conditions of the mushroom house and the uncomfortableness of the culture materials and improper management measures, the normal growth and development of mycelia and fruit bodies will be affected, which will affect the yield and quality. After the sowing, the hyphae did not germinate and the hyphae grew poorly after sowing. The strains did not germinate or eat, but only grew on the material surface and appeared atrophy. This is due to temperature, ventilation and improper humidity in the mushroom house. If the surface of the culture material is dry, it may be sprayed with calcium phosphate or potassium dihydrogen phosphate solution; if the material is too wet, the ventilation of the mushroom house shall be strengthened; when the temperature in the mushroom house is high, cooling measures shall be taken to make it reach a suitable temperature. Scope: When there is ammonia odor in the mushroom house, it is necessary to increase the amount of ventilation in time, poke holes in the material surface, and eliminate ammonia gas. After covering the soil, the mycelium grows too vegetatively after being sowed, and the villous mycelium grows densely, often emerging from the soil, forming a dense layer of impervious and airtight “bacterial quiltâ€. Mainly due to high temperature, high humidity caused mycelium leggy. To prevent mycelium "closure" is the measure when the mycelium grows out of the cover layer, to enhance the ventilation within the mushroom house, reduce the mushroom house temperature, humidity, and timely spray "snagged water" to facilitate the formation of the primordium. Do not spray water too quickly. Spray water when it cools sooner or later. Once the hyphae are found to be long, they must use a knife or bamboo to remove the bacteria. The hyphae of the overlying layer of mycelium are not soiled after 3-5 days of degraded soiling. The hyphae are gray and white, and the hyphae are not seen on the material surface. Even the material surface is black, which is caused by the shrinkage of the hyphae. The reason is that too much water is sprayed too quickly after covering the soil, resulting in lack of oxygen and making the hyphae suffocate. The water spray should be stopped immediately and the ventilation should be strengthened to facilitate the recovery of creeping mycelium. During the growth process of Botrytis edulis fruit body, due to the high temperature, the growth of fruiting bodies is fast, and the mushroom density is too large, the nutrient supply is not on, and thin-shelled mushrooms are prone to occur, and the yield is low and the quality is poor. In order to avoid this phenomenon, it is necessary to intensify ventilation during water spraying, increase the thickness of culture materials and soil layers, and strengthen the management of moisture and temperature during fruiting.
