First, hollow white root mushroom. Mushroom stalks become loose and white, and when they are severe, they shrink to form hollows. The causes are: In the fruit body growth stage, due to air drying and high temperature. When the relative humidity of the air is less than 85%, the water content of the cover soil is relatively low. When the air temperature in the mushroom room is above 18° C., the mushroom grows fast and the water evaporates quickly, causing the water absorbed by the mushroom body to be less than the transpiration water. Control methods: Spray water in time during the day so that the relative humidity of the air is kept at 90%. After the water is sprayed in the morning and in the evening, timely ventilation is needed to reduce the temperature of the mushroom shed and keep it at 14-18°C.
Second, hard open the umbrella: the separation of the veil and screen handle, open the umbrella too early, resulting in poor commercial. Reasons for the occurrence: At the beginning of the mushrooming, sudden encounter of low temperature, sudden drop of high temperature, large temperature difference, and low temperature of mushroom house. Control methods: to strengthen the mushroom shed insulation measures, pay attention to weather changes, narrow the temperature difference, and maintain the relative humidity of the air in the mushroom room within the appropriate range.
Third, dead mushrooms. Mushroom young mushroom wilting yellow, stop the growth of the final death, ranging from a total of death, while the weight of death. Causes: (1) The temperature is too high. At the beginning of autumn and early spring, the temperature is high, which causes the nutrition of the mushroom body to flow backwards and lack of nutrition. (2) The mycelium grows too fast after the soil is covered, the mushroom is denser, and the nutrient supply is not enough, causing the malnutrition of the mushroom and death; (3) The ventilation of the mushroom house is not In time, there is insufficient oxygen and high carbon dioxide concentration; (4) The mushroom shed has high temperature (more than 20°C), high humidity (over 95%), and the ventilation is not timely after spraying, and the surface area of ​​the mushroom is water, causing the mushroom to die of hypoxia and suffocation. Control methods: master the sowing time, prevent the mushrooming in the hot season; the sowing amount should not be too large to prevent the mycelium growing too prosperous, the fruiting too dense, resulting in lack of nutrients; the water content of the earth layer should not be too high, suppress the mushrooming part, and avoid Mushroom too dense, while spraying water cooling to timely ventilation to prevent mushroom surface water.
Fourth, thin skin open Umbrella mushroom: slender mushroom handle, thin cover, early open umbrella. Cause: The mushrooming period, mushroom room temperature above 20 °C, the air relative humidity is too large, poor ventilation, coupled with the bed mushroom out of the dense, out fast, competing for oxygen and nutrients caused. Control methods: Cultivation materials should be thoroughly fermented, timely ventilation after spraying, to prevent the mushroom surface area of ​​water, keep mushroom shed temperature suitable.
