High-yield cultivation of Pleurotus ostreatus with high nutrition formula
The high nutrition and high yield cultivation technique of Pleurotus ostreatus is to use wheat straw and straw as raw materials, adopt high nutrition formula, bacteria rod de-filming, nutrient soil covering and other measures, so as to make the input-output ratio more than 1∶10, and the economic benefit is very remarkable.
1. Changbai No. 1 isomethymic variety was selected for strain selection. The suitable cultivation time is from September to April.
2. There were 4 kinds of formula: ① soybean stalk (crushed) 50%, corn cob or wheat straw 40%, corn flour or wheat bran 8%, lime 2%. (2) wheat straw 70%, wheat bran 27%, compound fertilizer 1%, lime 2%. (3) straw 90%, cotton oil residue 10%.④ Cottonseed hull 50%, peanut hull 47%, phosphate fertilizer 1%, lime 2%. take one of that formula, crushing the raw material evenly, adjusting the water content to 55 - 60 percent, stacking, cover with plastic film, fermenting and sterilizing for 4 - 6 days.
3. Bagged sterilization Inoculation 1 kg ~1.25 kg per bag, sterilization at atmospheric pressure, inoculation after routine disinfection in inoculation room.
4. After inoculation, the bacteria bag is placed in the culture room. Generally, the stack height is 6 ~8 layers, the temperature is controlled at 23℃~26℃, ventilation is paid attention to, and the stack is turned once every 7 ~10 days. The bacteria can be developed in about 30 days.
5. The nutrient soil is prepared by mixing 40% of fresh cow dung or chicken manure, 40% of miscellaneous sawdust, 10% of quicklime, 8% of plant ash and 2% of calcium phosphate evenly, adding about 60% of water, stacking and fermenting, turning the pile when the temperature rises to 60 DEG C for 2 to 3 times, and then adding appropriate amount of fertile soil to obtain the nutrient soil.
6. Dig a pit with a depth of 25 cm to 30 cm in the greenhouse for covering the bacteria stick with soil, irrigate 2 days to 3 days in advance when the moisture content is insufficient, vertically place the bacteria bag in the pit after removing the film, fill the interval with nutrient soil, slightly expose the bacteria stick on the surface, irrigate the nutrient soil with 0.3% urea water, and then buckle the shed and shade the sun.
7. Management and harvest after about 15 days of soil budding, spraying water should be less, should be frequent, keep the relative humidity of the air at about 85%. After 3 ~5 days of bud emergence, when the bud will expand leaves, increase the number of spraying water into the air to maintain the relative humidity of the air at 85%~90%. After another 6 to 8 days, water can be sprayed on the ground to increase the number of sprays and increase the relative humidity of the air to more than 90%. Harvesting begins when the pileus edges unfold. After picking mushrooms each time, sprinkle a layer of plant ash, cover soil 2 cm ~3 cm after watering, remove soil after 10 days, manage according to the previous method, and harvest 4 ~5 tide mushrooms in total.

Double-sided mushroom production method in Pleurotus ostreatus bed
The double-sided mushroom production method is adopted in the Pleurotus ostreatus bed, which can not only make effective use of the room space, but also increase the yield per unit area of the mushroom bed. The main technical points are as follows: first, mushroom bed equipment. Bamboo or standing wood is used to build a frame in the mushroom room, which is generally 2 meters high and can be set up with three layers of mushroom beds, with an interval of 60ft 65 cm. The length depends on the actual situation of the mushroom house. There are two widths: 55 cm managed unilaterally and 110 cm bilaterally. The floor of each mushroom bed is nailed with thin wooden planks, with each branch 1.5 cm apart (gap). II. Inoculation of stall materials

Rapid cultivation of Pleurotus ostreatus in high temperature season
High temperature is extremely disadvantageous to the normal growth and high yield of Pleurotus ostreatus. If conventional cultivation methods are still used, not only the cost is high, but also the yield is low. However, if the rapid high-yield cultivation technique is adopted, high yield and high efficiency can be obtained. Summing up our experience for many years, the main points of rapid and high yield cultivation of Pleurotus ostreatus in high temperature season are as follows: there are many varieties suitable for Pleurotus ostreatus, and the quality of pure high temperature type is poor, so it is suitable to choose wide temperature but high temperature tolerant varieties. Such as Su Ping, Ai Kang 558, West Germany 33, Yaguang 1 and Gaoping 1, three Gorges 13.
