Six key points for high yield and stable production of bagged mushroom
First, the scientific selection of bacteria bags (a) bacteria bag specifications. In the actual production, according to different cultivation time, select the corresponding specifications of the bag. Use a 20 cm 40 cm or 22 cm 45 cm bag in the late summer and early fall, 24 cm 45 cm or 25 cm 50 cm bag in the fall, and a 25 cm 50 cm or 26 cm 52 cm bag in the late fall and winter months. Choose 25 cm 50 cm or 28 cm 55 cm bag in winter. (b) The quality of bacterial bags. Do not use high-transparency plastic bags for the bacterial bags, and use high-density, low-density polyethylene plastic bags that are slightly darker in color. (c) Preparation of bacterial bags. When the peasants are busy, they must fasten one end of the bacterium bag. The tether is about 20 centimeters long, and the head is 1.5 centimeters. 3~4 rows of holes can be drilled on the bacteria bag in advance, which saves labor and time.
Second, the selection and preparation of strains (a) selection of strains. According to the different cultivation time, the strains with different characteristics should be selected, and the cultivation of low temperature strains in the high temperature season and the cultivation of high temperature strains in the low temperature season should be firmly stopped. To select more varieties, feed batches, and supply different types of oyster mushrooms with the season. The strains of the same strain should undergo rotation cultivation. (b) Preparation of strains. Conditional best homemade strains to reduce costs. The original species can be prepared with wheat kernels, corn kernels, and sorghum kernels, and the cultivated species can be prepared with pure cotton seeds as much as possible, and some corn kernels can also be appropriately blended.
Third, building a mushroom house or mushroom shed can slightly transform the old house, the roof is transformed into a film roof, the wall is brushed with lime, and spray insecticides such as phoxim, dichlorvos, etc., and then smoked with sulphur; After the ground is leveled, a layer of 10-15 cm thick new soil is laid and a layer of plastic film is laid on the bacteria. It is also possible to construct a mushroom shed in the open space behind the village front house or pit ponds depending on the amount of feed. If the mushroom farmer's own conditions permit, it is better to build a standardized mushroom house or mushroom shed, batch feed, and carry out large-scale production.
Fourth, training materials formula and treatment (a) formula. 1. 100% cotton seed husk, 0.8% phosphorus nitrate potassium fertilizer, 802 or Nongfeng Hercules 10ml; 2. 50% cotton seed shell, 48% corn heart, 1% potassium phosphate fertilizer, 0.2% potassium phosphate, edible Bacteria nutrients 0.8%; 3. Corn heart 100%, compound fertilizer 2%, edible fungi nutrients 0.5%, salt 1.5%. The above formula is added 0.15% to 0.2% carbendazim and 2% to 3% lime powder. (b) Mixing. 1. Artificial ingredients. The amount of water used in the cement floor should be reduced to 130%; the brick surface should be thoroughly drained in advance to reduce the loss of nutritious water. When mixing artificially, it is faster to turn and mix in the first few times, and it is necessary to ensure that the mixture is even. 2. Mechanical mix. Large-scale cultivation of more use of mechanical mixing materials, mechanical mixing material to master the material moisture. (3) The time for adding lime powder and spraying insecticide should be staggered. First seasoning, after spraying. Fermentation material cultivation plus lime powder and spray fungicide should be staggered for 1 to 2 days. Raw material cultivation should be staggered for 2 to 4 hours. Whether it is blending or turning over materials, pest control is applied after adjusting the heap. (d) Inspection before bagging. When the raw material is cultivated in the low temperature season, the temperature of the material should not be too low. When the temperature rises to 20°C, it is bagged again. The adjusted material should not have any odor. If there is odor, 2% of alum or 5% of superphosphate solution can be sprayed. The pH of the material should be maintained at 8-9. After the material is stable, concentrate bags.
5. Clear division of labor when bagging (1) Feeders. Feeders should turn off seasonings, add ingredients, and seasonings. (b) For bacteria and seedlings. The bacteria-producing and breeding workers must disinfect the bacteria, use large pots or barrels to hold the disinfectant (potassium permanganate), dip the strains in the disinfectant water, and strip the bags after disinfection. In the high temperature season, plastic special kegs are used to hold the strains and one bagging worker is used. In the low temperature season, the strains can be directly stripped and put on the pile. (c) Baggers. When bagging, please pay attention to the tightness of the bag and avoid removing the lump when picking the mushroom. Before placing the hole in the bag, put the strain in the hole; The hem is uniform, so that the mycelium grows up and down evenly. (d) Bagging and bagging. The pocket baggers should stack the 3 to 5 layers of the bacteria bags at the temperature of the bags, lay a layer of plastic film on the place where the bacteria bags are piled, and sprinkle lime powder.
Sixth, the quality of bag management bacteria bag determines the level of Pleurotus ostreatus production. After bagging, the mushroom house or mushroom shed must always maintain a suitable temperature, and the environment should be partial dry and partial alkali. Mushroom farmers to produce a check clear card, the above indicated the appropriate temperature for the mycelium growth period, check every 2 to 3 hours, respectively, record detailed temperature, humidity and ventilation. After 7 days of bagging, the feed temperature can be basically stable. A number of thermometers should be placed between the upper and the lower left and right sides of the bag, not only to see the temperature in the room or in the shed, but also to see the temperature between the bags. As far as possible in the temperature of the bacteria, the temperature is maintained at 18 °C ~ 22 °C. When the temperature is high, the number of bacteria bags should be reduced. When the temperature is low, the film should be warmed.
