1. Base material formula: 300 kg of biogas residue, 200 kg of corncob, 10 kg of superphosphate, 1.5 kg of urea, 20 kg of lime powder, 5 kg of gypsum powder, 5 bags of mushroom disease, 240 g of edible mushroom three-dimensional nutrient.
2. Base material fermentation: In addition to three-dimensional sperm, the corn cob is directly mixed with fresh biogas residue and auxiliary materials, and the pile is fermented. When the temperature is above 20 °C, it is turned over once every day. When the third time is turned over, it is evenly sprayed 800 times. The phoxim solution is used to prevent insects and can be fermented for 7 days. The sign of the completion of fermentation: the base material is brown, there are a large number of actinomycetes, with special grassy smell, odorless, not sour, if there is sour smell, pungent rot, etc., it needs to spread the pile to emit moisture and smell. Reprocess. When the last turn, the three-dimensional sperm is sprayed evenly.
3. Seeding and germination: After the fermentation is completed, spread the pile, adjust the pH to about 8, and cool down to below 30 °C, you can bag and sow, routine operation can be. After sowing, immediately punch the micropores and move into the mushroom shed in the early sterilization process. During the period, every 3 days or so, spray the disease to the traceless solution, and check and mix it, and find that the pollution is treated in time to prevent spread and spread. . Under the condition of 25 °C, the bacteria can be completed in about 20 days, and then the post-ripening culture is carried out for about 10 days.
4. Covering soil: After completing the mature cultured bag, the soil is covered after the bag is removed. The thickness of the covering soil is generally 2 to 3 cm. If the material is made of grass or self-made humus, it can be covered to a thickness of 5 cm. The surface of the bed is leveled, and then the water is drenched to cover the soil. Pay attention to two points: one is to fill the soil between the columns; the other is to fill the water with light water to prevent the column from floating. Then cover the woven bag or newspaper class. After about 20 days, the hyphae appear on the surface of the bed, and the cover can be removed in time to enter the mushroom management stage.
