Master the key technology of Pleurotus ostreatus and let it produce more mushrooms in spring.
The technical measures to promote the mushroom production of the bacterial bag as soon as possible, the mycelial bag will be arranged in the mushroom field according to the planned mode of mushroom production, and it is best to open it by means of drilling, that is, in the middle and upper part of the mouth of the bag at both ends of the bag. Symmetrically insert two round holes with a depth of 2 cm and a diameter of 0.5 cm. Spraying auxin: 50-60 mg / L 30-alkanol was sprayed twice in 4-5 days after opening or release of the bag. The temperature was controlled at 15 ℃ ~ 18 ℃ in daytime and 2 ℃ ~ 7 ℃ at night, and the temperature difference was 10 ~ 15 days. Cover the watery plastic film on the mushroom bag. The ambient humidity increased to about 85%, and the scattered light reached 500 million 800 lux, increasing the number and time of ventilation in the mushroom shed, 2 / 3 times a day, 0.5 × 1 hour each time. In the cultivation method of high-quality Pleurotus ostreatus, the excess small mushroom buds are removed with a knife or bamboo stick, only a complete mushroom-shaped mushroom bud is left at the exit of each bag, and the temperature is controlled at 6 ℃ ~ 15 ℃ as far as possible. Spray water once or twice a day at a temperature of 6 ℃ ~ 15 ℃. Do not spray water directly on the mushroom body, spray water on the ground and air, and the environmental humidity is maintained at about 80%. Ventilated for 1-3 hours a day during the day, direct sunlight does not affect the growth and quality of Pleurotus ostreatus, and the color will not change. When the temperature is higher than 20 ℃, the sun should not shine directly on the mushroom body, because the strong light will make the mushroom body yellow. The fruiting body of Pleurotus ostreatus was harvested in medium well, when the appearance of the mushroom was white, the mushroom was dense and elastic, the edge of the cap was rolled in, and the folds were arranged neatly.

Off-season cultivation of volvariella volvacea in winter
The whole process of volvariella volvacea production is in the environment of high temperature and high humidity, and there are many insect pests and miscellaneous bacteria. Miscellaneous bacteria are mainly umbrellas, Trichoderma, Penicillium and so on. The main reasons for the occurrence of ghost umbrellas are high nitrogen content of raw materials, low pH value, incomplete fermentation and disinfection and so on. Trichoderma and Penicillium are mainly due to insufficient fermentation and partial temperature in the mushroom room.

Pleurotus ostreatus, also known as Pleurotus ostreatus, is a kind of large fleshy flat fungus with excellent quality, which is primitive and wild in arid grassland. after artificial cultivation, it is rich in protein, amino acid, glutamic acid and arginine. In addition, it is also rich in vitamin D and various mineral elements.
