High-yield cultivation techniques of Pleurotus ostreatus

Pleurotus nebrodensis is sensitive to temperature. Its hypha can adapt to a wide range of temperature, and can survive at 4~37℃. The optimum temperature range for fruiting is 0~24℃. The optimum temperature for budding stage is 8~13℃ in early growth stage, and 15℃ for young mushroom in late growth stage. The hyphal growth of Pleurotus nebrodensis needed a long period of post-maturity to reach physiological maturity. That is to say, after the mushroom bag is full of hyphae, it must go through a post-hypha ripening period before it can produce mushrooms. According to the characteristics of strains, this stage usually takes about 30~60 days, and some strains even take up to 80 days. The ripening period can be shortened greatly by artificial control measures. The basic method is to adjust the temperature to about 30℃ to make the mycelium fully develop, then reduce the temperature (move the bacteria bag into the low temperature refrigerator), maintain it in the environment of 0~10℃ for about 15 days, so that the mycelium can form self-protection under relatively uncomfortable conditions, thus accelerating its growth process. When the color of the bacteria bag is whiter than that of the earlier stage, the hardness of the hand feeling is higher and the elasticity is stronger, the bacteria bag can be removed from the cold storage and placed into the plastic greenhouse. To try to increase the temperature of the shed, increase humidity, give appropriate amount of strong light stimulation and greater ventilation. About a week or so, the inoculation block appeared slightly yellow bacteria solution. After that, the temperature should be lowered as much as possible until it is budding. Generally, this period is around mid-November, and the greenhouse temperature should be kept below 15℃. To cover the grass, strengthen the morning and evening and night ventilation, while strengthening the ground watering and space spraying. It only takes 1~2 days for the mushroom bud to form quickly under 10℃. Generally, each mushroom surface has only 1 - 3 mushroom buds. Before differentiation, only one bud was reserved, and a large, uniform, regular and white mushroom could be grown under normal conditions. This can effectively improve its commodity rate, generally each weight is about 200 grams, commodity rate nearly 100%.
