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 onset of winter, temperatures have remained low. To make oyster mushrooms grow quickly, many mushroom growers deliberately raise the shed temperature during the day. Generally, after about three in the afternoon, because ventilation continues, the temperature inside the shed begins to drop rapidly. Since most of the mushroom sheds currently in use are rather simple and poor at retaining heat, at night the temperature can fall to 4-5°C or even lower. Because the temperature is low, the substrate temperature is low.
Therefore, the ability of the mycelium to transport nutrients is very poor. When the daytime temperature is briefly higher, the fruiting bodies grow faster, but they cannot get an adequate 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 thin and long, and the caps are small. The solution is: while ensuring suitable ventilation, maintain a suitable temperature as much as possible. At night, the shed temperature should be kept above 8°C, and during the day, in this current season, try not to exceed 15°C, so as to prevent too large a temperature difference. Of course, mushroom sheds with heating facilities are an exception.
