The high yield of straw mushroom two-stage cultivation
The average bio-efficiency of the two-stage cultivation technology of straw mushroom is 58%, and 50 kg of fresh mushrooms can be produced for every 40 kg of raw material for 40 days. The output value is 300-400 yuan. First, the preferred strains of the selected species are straw mushroom V238 (large grain type), V20, V35 (medium grain type) as well. The culture age of the cultivated species used should be 15 to 20 days, and it is difficult for the old strains to seize high yields. Second, the raw materials are treated with golden yellow, dry, mildew-free rice and wheat straw, exposed for 2 to 3 days, and mechanically rolled into a soft, cottony grass. Formula: straw or wheat straw 100 kilograms, dry cow dung powder 10 kilograms, plant ash 5 kilograms, wheat bran or rice bran 3 kilograms, compound fertilizer 1 kilogram, gypsum powder 2 kilograms, after mixing various accessories, use 1:500 times more The fungicide solution is pre-wetted and mixed with the forage material. The 5% lime water (dry material ratio) is used to re-wet the forage material, so that the water content reaches 70% and the pH value is 12. Then build a heap fermentation, film insulation moisturizing. After the material temperature rises above 60°C, it is kept for 24 hours, and it is turned over 1 time; the temperature of the material is raised again to 60°C and maintained for 24 hours. When the material is tan and there are a large number of white actinomycetes, the temperature is lowered and the temperature is uniform. Sprayed 0.1% carbendazim solution in the material, fully mixed evenly, the fermentation period of 7 to 8 days. Third, the bagging fermentation culture bag should use 50 cm 24 cm 0.03 cm (length, width and thickness) of low-pressure polyethylene bags, first with a rope tied knot end of the bag mouth, in the bag bottom broadcast a strain of bacteria, loading a layer of material, Then broadcast a layer of bacteria, a layer of material, material surface with bacteria cover, a total of 2 layers of material, sowing 3 layers, and finally tied with a rope bag, each bag about 800 grams of dry material, the total seeding capacity 15%. After inoculation, the bag is placed in a clean and ventilated room for fermentation, stacking 1-2 layers, each bag spacing 20 cm, room temperature controlled at about 32°C, and air relative humidity 70%. After the strains survived and colonized, they loosened and loosened their mouth ropes to increase oxygen in the bags and promote mycelial growth. Under proper temperature conditions, the hyphae can be full of bags in about 10 days, and the pink chlamydospores are generated on the material surface, and then enter the fruiting period. Fourth, the site-building site can be used after the house before the house, the end of the field, all kinds of trees or melon bean shed, and other places to build field mushrooms. It requires a flat terrain, near water source, cleanliness, convenient drainage and irrigation. After selection, the soil is turned 5 to 10 centimeters deep, made into a 1 meter wide, 20 centimeters high, and an unlimited length of trampoline. It is wetted with 5% lime water and sprayed with 1:800 dichlorvos. 24 hours. 5. Take out the bag and take the mushroom. Put the mycelium that has been filled with mycelium into the boring machine after being unpacked. Each cylinder is 5 centimeters apart. The space is filled with fertile soil (Fat soil formula: 92.5% of garden soil, plus grass ash 5 %, compound fertilizer 03%, lime powder 2%), fertilizer soil pre-wet with 1% lime water to the hand into a group, touch the ground that is scattered, covering the fertilizer surface in the material 1 ~ 1.5 cm thick. The film is covered with a bamboo shed, covered with a pressure film and a straw curtain. The temperature inside the film is kept at 30 to 34°C and the humidity is 90% to 95%. After the tube is covered with soil, the mycelium can grow into the soil layer in 2 days. 5 to 7 Day soil surface can appear small buds. Sixth, management and collection of soil after the fungus tube should be sprayed 1 to 2 times a day, and appropriate ventilation. After a large number of mushroom buds are sprayed 2 or 3 times a day, the young mushrooms can be harvested for 3 to 5 days. After harvesting 1 tidal mushroom, 0.1% compound fertilizer should be sprayed on the surface of the mushroom. Wait 3 days later. Mushrooms can bud, generally can receive 4 ~ 5 tide mushroom.
