What is the cause of 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.
