What kind of sunshine, temperature and humidity does Pleurotus ostreatus need?

The growth environment of Pleurotus ostreatus to sunlight, temperature and humidity is as follows:

1. Temperature. The mycelium growth temperature range and suitable temperature of different species are not completely the same. Most species and varieties can grow at 5 ~ 35℃, and 2 ~ 3℃ is the same suitable temperature range for their growth. The optimum growth temperature of low-temperature and medium-low temperature varieties is 24 ~ 26℃, and that of medium-high temperature and wide temperature varieties is about 28℃.

2. Humidity. The optimum water content of substrate for mycelium growth is 6% ~ 65%. When the water content of substrate is insufficient, the growth of mycelium is slow, and the fruiting is delayed after the growth. Raw material cultivation, when the water content of the substrate is too high, has poor air permeability, slow mycelium growth, and is easy to breed anaerobic bacteria or molds. The optimum fruiting period is 7% ~ 75%. When the atmospheric relative humidity is 85% ~ 95%, the fruiting body grows rapidly and vigorously. When it is lower than 8%, the mushroom cap is easy to dry or crack, and when it is longer than 95%, it is easy to appear rotten mushrooms. In the cultivation of raw materials, the method of partial drying and supplementing water during the fruiting period is often adopted to ensure that the fungus is not infected by mold during the fruiting period and that there is enough water for the mushroom during the fruiting period.

3. light. The growth of Pleurotus ostreatus mycelium does not need light, but light inhibits the growth of mycelium. Therefore, dark or weak light environment should be given during fungus growth. However, the occurrence or growth of fruiting body needs light, especially the formation of fruiting body primordium. In addition, the light intensity also affects the color of the fruiting body and the length of the stalk. In contrast, under strong light conditions, the fruiting body is darker in color, shorter in stalk, thicker in meat and better in quality; When the light is insufficient, the fruiting body has light color, long stalk, thin meat and poor quality.
