Cultivation materials and recipes Various crop straws (such as wheat straw, bean straw, corn stalks, etc.) and waste (such as cottonseed hulls, corn kernels, peanut husks, etc.) can be used to cultivate oyster mushrooms. The commonly used cultivation recipes are: (1) 55 kg of cottonseed husk, 35 kg of bean stalk, 5 kg of bran, 2 kg of bean cake, 1 kg of superphosphate, 1 kg of gypsum, 1 kg of lime, and 0.2 kg of urea. (2) 60 kg of corn, 35 kg of corn stalk, 2.5 kg of gypsum, 0.2 kg of urea, and 2.3 kg of superphosphate. (3) 78 kg of peanut shells, 20 kg of bran or rice bran, 1 kg of gypsum, and 1 kg of sucrose. (4) 80 kg of straw or straw, 5 kg of bran or rice bran, 10 kg of corn flour, 2 kg of superphosphate, 1 kg of gypsum, 1 kg of urea, and 1 kg of sucrose.

Culture material treatment and fermentation (1) treatment. The corn kernels are crushed into soybean-sized granules, the peanut shells are crushed, and the other stalks are cut into small pieces and crushed. Clean the premises before mixing and disinfect with 0.2% carbendazim or 3%-5% lime water. During the seasoning, gypsum, phosphate fertilizer, sucrose, urea and other water-soluble excipients are dissolved in clean water to make a mixture, and then the insoluble materials are mixed evenly from little to more, and finally the mixture is mixed. Excipients and main ingredients are evenly mixed, and water is added to make the water content in the feed approximately 60% (a watermark is firmly grasped between the fingers of the culture material but there is no water drop). (2) Fermentation. The prepared culture material is made into a trapezoidal pile with a width of 1.5 meters at the bottom, a width of 1 meter at the bottom, a height of 0.8 to 1.2 meters, and an unlimited length. A hole is inserted into the center of the material every 40 centimeters with a fine wooden rod. When the temperature in the material rises to 60°C, it is maintained for 24 hours and then it is turned over once. Wait until the temperature rises again to 60°C for another 24 hours, then turn over again.

Sowing (1) strain selection. Pleurotus ostreatus has four types of temperature: low temperature, low temperature, medium temperature and high temperature. According to the different climatic characteristics of the local area, the temperature type should be selected. The low temperature type and the low temperature type should be selected in early spring, late autumn and winter, and the medium temperature type in spring and autumn. , Choose high temperature type in late spring, early autumn and summer. (2) sowing. Fermentation cultivation is better for bagging, and 25x60 cm polyethylene or polypropylene plastic bags can be used.

The bacteria inoculated the inoculated good bacteria bags into the mushroom shed. When the temperature is low, they can be placed into four layers of helium. Thermometers are inserted between the bacterium bags and inspected several times a day. When the material temperature exceeds 30°C, it is turned over in time. After about 25 days, the mycelium can be full and transferred into the mushrooming stage.

Mushroom management solution to the rope on the good bacteria bags, will open the bag, keep the relative humidity within the mushroom shed at about 90%, increase ventilation and lighting, soon will form a large number of mushroom buds. Then increase the amount of water spray, so that the relative humidity of air in 95% -98%, increase ventilation, in order to facilitate the formation of fruiting bodies.

Harvest from the bud formation to fruit body maturation generally 5-7 days. The best time for the harvest of Pleurotus ostreatus is that the fruiting body matures on the 89th, ie, the edge of the cap has not been flattened, and there is no white fuzz at the junction of the cap and stipe. The first tidal mushroom timely replenish moisture after harvest to facilitate the growth of the lower tidal mushroom.
