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 and weak, the temperature is too high, the ventilation is poor, or the infection of insect pests will cause the phenomenon of "sterilization". Improving the above conditions can prevent the occurrence of "sterilization".

New technology of producing mushroom in Pleurotus ostreatus bed
The indoor frame cultivation of Pleurotus ostreatus usually produces mushrooms only on the front of the bed, and its production capacity has not been brought into full play. If the positive and negative sides of the mushroom bed are produced at the same time, the average yield of mushrooms per square meter can be 15.5 kg per square meter without increasing the formula of culture material per unit area and the seeding amount, of which the negative side produces 7.6 kg mushrooms, which is nearly twice as much as that only in the positive side, and the mushrooms can be produced about 7 days earlier. The following introduces the main technical points of mushroom production on both sides of the Pleurotus ostreatus bed: the setting of the frame structure of the mushroom bed

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, and the temperature is higher in a short time during the day.
