Cultivation of Coprinus comatus with biogas residue

1. Base material formula: 300 kg of biogas dregs, 200 kg of corncob, 10 kg of calcium superphosphate, 1.5 kg of urea, 20 kg of lime powder, 5 kg of gypsum powder, 5 bags of mushroom disease, 240 grams of three-dimensional nutritional essence of edible fungi. 2. Base material stacking fermentation: in addition to three-dimensional essence, the corncob is directly mixed with fresh biogas residue and auxiliary materials, and fermented. Turn the pile once a day when the temperature is above 20 ℃. When turning the pile for the third time, evenly spray 800x phoxim solution to prevent insects and pile up fermentation for 7 days. The sign of the completion of fermentation: the base material is brown, there are a large number of actinomycetes, with special grass smell, odorless, non-acid, if there is sour smell, pungent rot smell, etc., it is necessary to spread out the material stack to distribute moisture and smell for re-treatment. When turning the pile for the last time, spray the three-dimensional essence evenly. 3. Sowing and sending bacteria: after the completion of fermentation, spread out the material pile, adjust the pH value to about 8, and lower the temperature to less than 30 ℃, you can bag and sow seeds, just do the routine operation. Immediately after sowing, micro-holes were made and moved into the mushroom shed which was sterilized in advance to enter the sterilization period; during this period, the traceless solution was sprayed every 3 days or so, and the contamination was checked and removed to deal with the pollution in time to prevent spread and spread. Under the condition of 25 ℃, the bacteria could be produced in about 20 days, and then maintained for about 10 days for post-ripening culture. 4. Cover soil bacteria: after the completion of the mature culture of the bacteria bag, take off the bag to cover the soil, the thickness of the soil is generally 2cm 3 cm, such as the use of peat soil material or self-made humus material, the thickness can be up to 5 cm, after covering the soil, the surface of the material bed will be leveled, and then irrigation will cover the soil thoroughly, pay attention to two points: first, the bacteria column should be filled with cover soil; second, slow water and light irrigation should be used during irrigation to prevent the bacteria column from floating. Then cover the woven bag or newspaper, after about 20 days, the mycelium appeared on the surface of the material bed, and the cover can be removed in time to enter the management stage of mushroom production.
