Last Updated: 2024/11/22, The cultivation of Pleurotus eryngii with biogas residue has the advantages of developing new resources and saving costs, and generally reduces the production cost by about 30%. The operation techniques before the cultivation of Pleurotus eryngii with biogas dregs are introduced as follows: 1. Biogas residue treatment: spread the biogas dregs extracted by farmers' biogas digester on the flat ground, let them aerate and dry to moisture content.

The cultivation of Pleurotus eryngii with biogas residue has the advantages of developing new resources and saving costs, and generally reduces the production cost by about 30%. The operation techniques before the cultivation of Pleurotus eryngii with biogas residue are introduced as follows: 1. Biogas residue treatment: spread the biogas dregs extracted by farmers' biogas digester on the flat ground, allow them to aerate, dry to less than 15% moisture content, and store them. 2. Base material formula: 300 kg of biogas residue (calculated by air-dried material), 300 kg of corncob, 30 kg of wheat bran, 10 kg of calcium superphosphate, 2 kg of urea, 30 kg of lime powder, 5 kg of gypsum powder, 6 bags of mushroom disease elimination, 240 grams of three-dimensional nutritional essence of edible fungi. 3. Sterilization: crush the corncob to the size of peanuts. All raw and auxiliary materials are mixed with water to make the moisture content reach 60%-63%. When sterilizing under atmospheric pressure, the polyethylene mushroom bag with a width of 17 cm to 22 cm should be loaded, and when high pressure sterilization is adopted, it should be replaced by polypropylene mushroom bag. Sterilization should be carried out as soon as possible after bagging: normal pressure sterilization should be maintained for 8 hours when 100 ℃ in the bag, 3 hours for high pressure sterilization, and 6 hours for high pressure steam sterilization. Non-flow operation, after the completion of sterilization, another night of boredom, the effect is better. 4. Sowing and spreading bacteria: when sterilization is completed and cooled to less than 28 ℃ or at room temperature, inoculation can be carried out, and routine operation can be done. During the infection period after inoculation, the traceless solution was sprayed every 3 days or so, and the inspection was carried out to deal with the pollution in time to prevent spread and spread. Under the condition of 25 ℃, the bacteria can be completed in about 25 days, and then maintained for about 15 days for post-ripening culture to facilitate the explosive emergence of Pleurotus ostreatus. The management of mushroom production period is the same as the routine.
