What is the reason for the deformity of Pleurotus ostreatus
The occurrence of Pleurotus ostreatus deformity should have a lot to do with the great temperature difference between day and night. Since the beginning of winter, the temperature has been on the low side. In order to allow Pleurotus ostreatus to grow rapidly, many mushroom farmers deliberately raise the temperature of the greenhouse during the day. Generally speaking, after about three o'clock in the afternoon, the temperature in the shed begins to drop rapidly because of continued ventilation. As most of the currently used mushroom sheds are relatively simple and have poor heat preservation performance, at night, the temperature can drop to 4-5 ℃ or even lower, because the temperature is low and the material temperature is low. Therefore, the ability of mycelium to transport nutrients is very poor. Under the condition of high temperature for a short time during the day, the fruiting body grows faster, but does not get enough nutrition supply, so the fruiting body grows very different from the normal temperature season. Small blossoms, light weight, slender legs and small mushroom slices. The solution is: under the premise of ensuring proper ventilation, try to ensure a suitable temperature, the greenhouse temperature should be kept above 8 ℃ at night, and during the day, in this season, try not to exceed 15 ℃, so as not to cause excessive temperature difference, except for mushroom sheds with heating facilities.

What if Pleurotus ostreatus appears "disruption" and "sterilization"?
After inoculation, the normally growing hyphae were dense, thick and white, developed forward in a fan shape, and the cotton shell material decomposed by the hyphae turned yellowish brown. If a certain section of mycelium breaks and does not connect, it is called "broken bacteria". This situation is caused by excessive water content of culture material and high temperature during the culture period. Choosing the appropriate humidity and temperature can prevent the phenomenon of "breaking bacteria". The phenomenon of degeneration and shrinkage of the hyphae that has grown on the culture material is called "de-sterilization". The culture material is too dry and loose, the mycelium is weak, the temperature is too high, the ventilation is poor, or it is infected by insect pests.

Occurrence and Prevention of Common Diseases of Pleurotus ostreatus
In recent years, with the expansion of Pleurotus ostreatus cultivation area and the increase of cultivation years, the damage of pests is becoming more and more common, and the trend of occurrence is early and fast, and there is no harvest in serious cases. Because Pleurotus ostreatus is sensitive to pesticides and easy to produce drug damage, it is difficult to achieve the effect of killing insects and protecting mushrooms when the pests occur. Therefore, identifying the damage characteristics of various pests and reducing the source of infection are effective measures to avoid and reduce the occurrence of insect pests. Species of pests 1. Eye bacteria mosquitoes are also known as sharp-eyed bacteria mosquitoes, commonly known as small black mosquitoes, small flies, white maggots (refers to larvae). Diptera, mosquitoes
