Summer cultivating oyster mushrooms, sometimes there will be a large number of small mushroom deaths after mushrooming. The main reasons are as follows: Preventive measures should be taken as soon as possible.
Temperature is too high
After the primordium of Pleurotus ostreatus is formed, if the temperature is high (above 30 °C), the cap will gradually wither, causing a large number of deaths of the mushroom. During the mushrooming period, the temperature is too high, and the mushroom room can be sprayed with well water to cool down. Outdoor mushrooming, mushroom sheds should be covered with thick straw or straw to enhance the ventilation.
Lack of water
After the young buds of Pleurotus ostreatus are formed, if the relative humidity of the air in the mushroom chamber or shed is less than 80%, the small mushroom body will wither and die due to lack of water. After the bud, spray water 4 to 5 times a day. When spraying, make it less, even and fine, so that the relative humidity is kept at about 90%.
Excessive water spray
During the expansion of Pleurotus ostreatus, if it is too much water, it is easy to edema, yellowing and ulceration, and it is easy to be infected with bacteria and die. Therefore, when spraying water on the mushroom house (shed), spray the water on the ground and surrounding walls, and do not spray directly onto the fruiting bodies of the young mushrooms. At the same time, it is necessary to correctly grasp the amount of water sprayed, and do not spray too much.
Poor ventilation
When the concentration of carbon dioxide in the mushroom chamber or shed exceeds 0.5%, it is easy to form a bigfoot mushroom that is as big as a fist or a small handle. In general, it is necessary to strengthen the ventilation and ventilation to ensure that the air in the mushroom room (shed) is fresh. This should be paid special attention at high temperatures.
