How to prevent dead mushrooms in summer?

How to control dead mushrooms in summer when planting Pleurotus ostreatus? Please introduce the method of bag cultivation of Pleurotus ostreatus in summer, sometimes a large number of small mushrooms die after mushroom emergence, the main reasons are the following four points, preventive measures should be taken as soon as possible. After the primordium of Pleurotus ostreatus is formed at high temperature, if the temperature is higher than 30 ℃, the cap will gradually wither and a large number of small mushrooms will die. If the temperature is too high during mushroom production, well water can be used to spray the mushroom room to cool down. When growing mushrooms outdoors, the mushroom shed should be covered with thick straw curtains or straw to cover the sun, and strengthen ventilation. After the young buds of Pleurotus ostreatus with lack of water are formed, if the relative humidity of the air in the mushroom or shed is less than 80%, the mushroom will wither and die due to lack of water. After budding, water should be sprayed 4 or 5 times a day, with less, uniform and fine water spray, so that the relative humidity can be kept at about 90%. Excessive water spraying during the expansion of Pleurotus ostreatus fruiting body, such as spraying too much water, it is easy to edema, yellowing and ulceration, and it is also easy to be infected with bacteria and die. Therefore, when spraying water to the mushroom house (shed), the water should be sprayed on the ground and surrounding walls, not directly on the fruiting body of young mushrooms. At the same time, we should correctly grasp the amount of spray water, do not spray too much. When the concentration of carbon dioxide in the poorly ventilated mushroom or shed exceeds 0.5%, it is easy to form big-foot mushrooms as big as fists or thick covers with handles. At ordinary times, it is necessary to strengthen ventilation and ventilation to ensure that the air in the mushroom (shed) is fresh, which should be paid special attention to at high temperatures.
