Raw material formula (1) 60% wheat straw, 25% dry cow dung, 12% wheat bran, 3% corn flour. (2) Corncob 40%, bean straw 45%, wheat bran 12%, and cornmeal 3%. (3) Pleurotus ostreatus waste 40%, bean straw 45%, wheat bran 12%, and cornmeal 2%. For each of the above three formulas, 0.5 kg of special fertilizer for Coprinus comatus, 25 kg of quicklime, 2 kg of carbendazim 0.1 kg, 0.02 kg of magnesium sulfate, 0.005 kg of zinc sulfate, and 60 kg to 80 kg of water are added for every 50 kg of culture material. Raw material processing The corn stover, bean stalk, straw and other straws are fully dried and crushed, so that the corn kernel granules have the same size as the corn kernels. Wheat stalks, rice straw, and soybean stalks are equivalent to crumb crumbs, so that the air permeability is good, the water holding capacity is strong, and the suitable bacteria are Silk growth. The mixing method adopts "pile-through oxygen fermentation method" to mix ingredients. (1) Spread the dry material on the worm-killed ground, add dry fertilizer according to the amount of special fertilizer, water and quicklime needed in the formula, mix it and pile it into earth samples, and put even more pores on the heap. The insecticide was sprayed on the surface of the pile, covered with plastic film, and surrounded by oxygen. Wait until the temperature rises to 62°C and turn for 48 hours. (2) Adding various auxiliary materials while turning the stack, mixing and then stacking, pricking holes to fight drugs, covering the membrane, waiting for the material temperature to rise again to 62°C, and maintaining 36 hours for turning. (3) Spray carbendazim while turning over the heap, adjust the moisture content to 65%, adjust the pH to 8 with quicklime, mix thoroughly, and wait until the feed temperature drops below 25°C. Bagging and bacteria generation adopts the technique of “pore and oxygen bagging at both endsâ€, using a low-voltage polyethylene plastic bag with a diameter of 26 cm and a length of 45 cm, with three layers of material, sowing four layers of seeds, with a seed volume of about 18%, and two bags. End with a diameter of 10 mm to 12 mm thick sticks, each tie 4 to 5 vents, the depth of the bag length 1/2, 15 days to 20 days mycelium filled with bacteria bags, covering the soil. Cultivated soil management Cultivated Coprinus comatus mainly uses a 70 cm-long isolation strip of the cucumber shed. The length of the shed is digging a ditch with a depth of 40 cm and a width of 65 cm. The cover is covered with 10 cm of fermented straw and wheat straw. Bacteria bag membranes are placed in three rows within the bowl. The spaces are filled with soil and the bags are covered with soil 3 cm to 3.5 cm thick. After covering the soil, use high-performance cypermethrin and clotrimyl, and pour through the water 2 days to 3 days later. After 15 days to 20 days, coprinus comatus was abundant. In the fruiting body when the fruit cap is removed from the stipe, to ensure the quality of the product, after the completion of a tidal mushroom, fill the nutrient water (100 kg of water plus 0.2 kg of potassium dihydrogen phosphate), spray once again, high efficiency cypermethrin, mushroom 4 Tide to 6 tides.
