1. Processing of Volvariella volvacea raw materials: selecting new wheat straw, corn and cottonseed hull as raw materials. Taking wheat straw as an example, it was soaked in 3%-5% lime water for 24 hours, then drained, and then mixed with gypsum, livestock manure, phosphate fertilizer, plant ash, etc. When straw is fermented, as usual, the pile width is 1.2 m, the pile height is 1 m, and the length is greater than 1 m, and air holes should be properly drilled in the pile. After folding, cover with film to moisturize. Compost should be soft, with a water content of 70% and a pH value of about 9.

2. Ridge cultivation is a new method for high yield of Volvariella volvacea, which adopts three-layer ridge cultivation. First, spread the culture material at high altitude, with a width of 30-40 cm and a thickness of 10 cm, and sow a layer of strains along the periphery. Wet the wheat bran with 3% lime water and put it in the mushroom house to stop the secondary fermentation. Spread a layer of wheat bran belt with a width of 10 cm in the middle of the seeds, and spread a second layer of culture material, such as planting wheat bran as above, spreading a layer of culture material on it, sowing a layer of strains on the surface of the material, and covering the film.

3. After planting Volvariella volvacea, keep the temperature of the culture medium at about 36℃ and uncover the film for 2-4 days. Then cover the bed with a thin layer (65,438+0 cm) of fertile sandy loam, spray more than 65,438+0% lime water on the soil layer to keep the soil layer moist, and then cover it with plastic film. After covering the soil, the room temperature is controlled at about 30℃, and the material temperature is controlled at about 35℃. Properly ventilate under the condition of ensuring the proper material temperature. Spray mushroom water 1 time on the 4th to 5th day, and properly ventilate after spraying, so as to prevent the vent from being closed immediately after spraying, otherwise the mycelium will grow white. In general, young mushrooms begin to form 6-7 days after planting. At this time, attention should be paid to heat preservation and moisture preservation and proper ventilation. Keep the temperature of the culture medium at 33-35℃, and the relative humidity of the air in the shed at about 90%, and insist on a certain amount of scattered light. If the temperature is not suitable, spray the young mushrooms indirectly with water. If the humidity is not high enough, spray them with water around 30℃. Mushrooms can be harvested in about 10 days after planting.
