What causes deformed oyster mushrooms?

The occurrence of deformed oyster mushrooms should be largely related to the large temperature difference between day and night. Since the arrival of winter, temperatures have remained low. In order to make oyster mushrooms grow quickly, many mushroom growers deliberately raise the greenhouse temperature during the day. Generally, after about three o'clock in the afternoon, because ventilation continues, the temperature inside the greenhouse begins to drop rapidly. Since most of the mushroom greenhouses currently used are relatively simple and have poor insulation, at night the temperature can drop to 4-5°C or even lower. Because the temperature is low and the substrate temperature is low, the mycelium's ability to transport nutrients is very poor. When the daytime temperature is briefly higher, the fruiting bodies grow faster, but they cannot get enough nutrient supply, so the fruiting bodies grow very differently from those in seasons with normal temperatures: the caps are small, the weight is light, the stems are slender and long, and the caps are small. The solution is: under the premise of ensuring suitable ventilation, maintain a suitable temperature as much as possible. At night, the greenhouse temperature should be kept above 8°C. During the day, in the current season, try not to exceed 15°C to prevent too large a temperature difference. Of course, mushroom greenhouses with heating facilities are an exception.
