The thin skin of mushroom opens the umbrella early.
Symptoms: thin cover of fruiting body stalk and opening of umbrella early.
Causes: the mushroom density is too high, the temperature of the mushroom room is too high, the air relative humidity is not enough, the soil layer on the bed is dry, the fruiting body grows fast, and so on, will form a thin skin and open the umbrella early.
Preventive measures: properly control the mushroom position, the ventilation time of the mushroom room should be selected in the morning and evening, reduce the temperature of the mushroom room, and appropriately increase the moisture of the soil layer on the bed and the relative humidity of the air.

8 steps of mushroom fertilization
In the process of mushroom production, generally after three harvests, the nutrients of the culture material decreased, the acidity increased, the mycelium vitality weakened, and the yield and quality decreased. In order to achieve high quality and high yield of mushrooms, supplementary fertilizer must be applied. The specific methods are as follows: 1. Boil the rotten pig and cow urine for 20 minutes, spray 10 ~ 20 times of water after filtration, and then spray with water for 1 time. 2.

Control of mushroom pathogen
Mushrooms begin to emerge one after another in late September, which is also the time when mushroom pathogens begin to multiply. Mushroom walnut fleshy fungus is a serious pathogen in mushroom production. This bacteria is also known as "pseudotruffle", and its pathogen is Microsporum. The ascomycetes are in the shape of walnut meat or cauliflower when piled, light yellow to creamy and light brown when ripe. The surface is covered with dandruff, the fungus is dense and soft, and has a fishy smell after being crushed, up to more than 10 centimeters. Once the mushroom bed is infected by walnut fleshy bacteria, the bed should stop spraying immediately.
