1. Do a good job of pretreatment. Spread it on the cement floor or plastic film for a week in advance to dry, and turn it over from time to time to evaporate the pungent smell while sterilizing. After removing impurities, stir in lime powder at about 4% of the dry grain weight to reduce acidity.
2. The formula of the culture material has a low lignin content. Sawdust should be added in the ingredients to meet the needs of lignin and aeration for mycelial growth. The formula requirements are as follows: â‘ Sorghum or rice, wheat gluten 77%, rice bran or bran 5%, sawdust 15%; â‘¡barley, broken rice beer is 77%, and wood chips 20%; â‘¢sorghum, husk white is 77%, rice bran or bran 15% , Sawdust 5%. Add 1% of superphosphate, gypsum powder, and lime powder to each formula. The moisture content of the material is controlled at 60% to 65%.
3. Pack the culture material in a polyethylene bag of 17cm×33cm specification for bagging and sterilization, and shake it while packing to make it loose. Gently press the material 6-8cm away from the bag mouth, do not press it tightly, and then tie the rope into a slip knot. Because it contains thermophilic acid-resistant bacillus and other miscellaneous bacteria, the sterilization must be thorough. This is the key to the successful use of the bacteria. Sterilization adopts normal pressure twice intermittent method, that is, keep for 4h after shanghai, extinguish the flame and reduce to 30℃ for heat preservation, after 1~2d, reheat to 100℃ for 4h.
4. After the temperature of the inoculum drops to 30℃, rush to inoculate it in the inoculation box, and then move it to room temperature to develop bacteria. During this period, in addition to keeping the temperature and humidity appropriate, pay attention to turning the pile and checking for impurities. There are bacteria spots on the bacteria bag. , Should be removed in time, and then immediately inject 0.2% carbendazim solution.
5. Fruiting management During the fruiting period, the material surface is easy to be infected with various bacteria. Once found, it should be dug up together with the culture material, or smeared with thick lime water, ventilated 2 to 3 times a day, sprayed water 2 to 3 times, and keep the indoor relative Humidity is 85%～90%. If it can be managed according to the above requirements, generally 100-120kg of fresh fungus can be harvested per 100kg of dry grains. This is a good project for farmers to get rid of poverty and become rich, and it is worth promoting.
