Outdoor bag planting black fungus fast yield high yield technology
First, the optimal temperature for selecting the fruiting body in the season is 22~26°C. Spring cultivation should be selected before mid-May to mid-May, inoculation should be in 2 to 3 months; autumn can be produced in mid-July to mid-August, and the ear is best from September to October. Second, the choice of raw materials, cottonseed husk, miscellaneous wood chips, soybean stalks, straw, bagasse, reed crumbs, corn cobs, weeds, etc. can be used for cultivation materials; bacteria bags should use polyethylene plastic bags, length 55 cm, width 15 cm or 12 cm. Third, the medium preparation 1 dry bagasse or cotton seed hull 100 copies, 20 copies of rice bran or bran, calcium carbonate or gypsum 2 copies, 0.3 copies of magnesium sulfate, 1 serving of sugar, 115 to 120 servings of clear water; 2 dried bagasse or cottonseed 100 shells, 15 portions of bran, 0.3 parts of urea, 0.2 parts of potassium dihydrogen phosphate, 2 parts of calcium carbonate or gypsum, 1 part of sugar, 0.3 parts of magnesium sulfate, 115 to 120 parts of clear water, 3 parts of 100 pieces of miscellaneous wood, bran 20 parts, 1 part sugar, 1 part plaster, 0.2 part urea, 0.3 parts magnesium sulfate, 110 parts water 120 parts; 4 Stir the raw materials first, and fashion bags, elastic and uniform, without any gaps, play 3~4 Hole, sealed with tape or tape. Fourth, sterilized bagging immediately into the pressure cooker sterilization, the temperature rose to 100 °C to maintain 10 to 12 hours, the temperature can not be ignored when the temperature is high and low, but also be careful not to boil the water in the pot. V. Inoculation bacteria sterilization after the bag control at about 28 °C, inoculated into the inoculation room. Generally use 750 grams of bottled strains, each bottle can receive 20 to 25 bags. Pay attention to aseptic operations. Cultivated species should be disinfected before inoculation. Bacteria bags and inoculation kits should be cleaned in advance with benzalkonium chloride (0.1 kg) and water (5 kg). The strains also need to be cleaned with a benzil rinsing bag or bottle, and then placed in the inoculation box or inoculated. room. The bacteria bag and inoculation kit were mixed and fumigated with formalin and potassium permanganate for 3 to 4 hours before inoculation. When the inoculation was lifted, the tape was peeled off, and the broad bean size bacteria blocks were quickly inserted and immediately sealed with a tape, and the cultivation bag hyphal cell culture room was placed at a suitable temperature of 25 to 27° C., 8 to 10 layers were piled, and covered with clean sacks for insulation. It should be close to darkness. Temperature of mycelium development stage should be controlled within 30°C. After 3 to 5 days after inoculation, the white fluffy hyphae can grow, and no hyphae need to be reseeded after 7 days. Ventilation twice a day after inoculation, 15 to 20 days if the mycelium has not filled the bag, should open the corner of the tape ventilation. 30~35 days when the primordium begins to form, it can be moved to the field trampoline. After 2~3 days, 16~20 knives are cut alternately on the fungus bag with a small blade to facilitate venting of the ear and cover the membrane. Six, field trampoline ear management 1 ear shed to convection ventilation, field ear shed "four positive and six negative" humidity 90 to 95%; 2 ventilation 2 to 3 times a day, remove film ventilation 1 to 2 hours, the temperature is higher than Strengthen ventilation and trampoline water spray at 32°C; 3 spray water to reduce temperature at long-term ear temperature over 32°C; 4 ear pick-up standard is 3 to 5 cm, use gently and gently, then reduce or stop water spray. After the completion of the operation, the ventilation should be increased, the bad ear should be removed, and the white mycelium should be grown at the cutting mouth to increase the light, reduce the ventilation, and adopt space spray, water spray in the trampoline or irrigation in the ditch. Normal management. Inoculation can generally receive 4 or more. VII. Harvesting and Processing 1 Picking should be carried out under the ear base. The ear base of long ear buds can be left behind; 2 the ear under the harvest can be dried in the sun in time, and can be dried by rain dryer. The finished product is packed in double plastic bags.
