Scientific selection of bacterial bags 1. Specifications of bacterial bags: In actual production, the bacterial bags of corresponding specifications should be selected according to different cultivation time. In the late summer and early autumn, choose a 20×40 cm or 22×45 cm fungus bag, in autumn, choose a 24×45 cm or 25×50 cm fungus bag, and in the late autumn and early winter, choose a 25×50 cm or 26×52 cm fungus bag. In winter, choose 25×50 cm or 28×55 cm fungus bags.
2. Quality of bacteria bags: Do not use plastic bags with high transparency, but high-density low-pressure polyethylene plastic bags with a slightly darker color.
3. Bacteria bag preparation: When the farm is idle, first tie one end of the bag, the tether is about 20 cm long, and the head is 1.5 cm when it is tied. 3 to 4 rows of holes can be punched in the bacteria bag in advance, which can save labor and time.
Selection and preparation of strains 1. Selection of strains: selection of strains with different characteristics according to different cultivation times to prevent cultivation of low-temperature strains in high-temperature seasons and cultivation of high-temperature strains in low-temperature seasons. It is necessary to select several varieties, feed them in batches, and supply different types of oyster mushrooms according to the season. Rotation cultivation of strains of the same strain is required.
2. Preparation of strains: the best homemade strains with conditions to reduce costs. The original seeds can be prepared with wheat kernels, corn kernels, and sorghum kernels, and the cultivated seeds are prepared with pure cotton seed husks as much as possible, and some corn cobs can also be appropriately mixed.
When building a mushroom house or mushroom shed, the old house can be slightly modified, the roof is transformed into a film roof, limestone is painted on the wall, and insecticides such as phoxim and dichlorvos are sprayed, and then smoked with sulfur; After flattening, lay a layer of new soil 10 to 15 cm thick, and then lay a layer of mulch when germs grow. It is also possible to build a mushroom shed in the open space behind the front house of the village or by the pit according to the amount of feed. If conditions permit, it is best to build a standardized mushroom house or mushroom shed, batch feeding, and large-scale production.
Culture material formula and treatment 1. Formula â‘ 100% cotton seed husk, 0.8% nitrate phosphorus and potassium fertilizer, 802 or Nongfeng Hercules 10 ml.
â‘¡Cotton husk 50%, corn cob 48%, nitrate phosphorous potassium fertilizer 1%, potassium dihydrogen phosphate 0.2%, edible fungus nutrients 0.8%.
â‘¢ Corncob 100%, compound fertilizer 2%, edible fungus nutrient 0.5%, salt 1.5%.
The above formula is added 0.15% ~ 0.2% carbendazim and 2% ~ 3% lime powder.
2. Mixing â‘ Artificial mixing: the water consumption of the cement floor is reduced to 130%; the brick surface is watered in advance to reduce the loss of nutrient water. When mixing materials manually, the mixing should be quick in the first few times to ensure even mixing.
â‘¡Mechanical mixing: Mechanical mixing is mostly used for large-scale cultivation, and it is necessary to grasp the moisture of the material.
3. The time of adding lime powder and spraying insecticide should be staggered. The adding of lime powder and spraying fungicide should be staggered for 1 to 2 days, and for raw material cultivation, it should be staggered for 2 to 4 hours. Regardless of whether it is admixture or turning, after adjusting the pile, it should be sealed with insecticide to prevent insects.
4. Check the raw material cultivation in the low-temperature season before bagging, the material temperature should not be too low, when the temperature rises to 20 ℃, then bag. The prepared material should not have odor. If there is odor, spray 2% alum water or 5% superphosphate clear liquid. The pH value of the material should be kept at 8-9. After the material is stable, bag it together.
Bacterial bag management The quality of the bacterial bag determines the output of Pleurotus ostreatus. After bagging, the mushroom room or mushroom shed must always maintain a suitable temperature. The mushroom farmer should make a check card clearly stating the appropriate temperature required for the growth of the mycelium. Check it every 2 to 3 hours, and record the detailed temperature, humidity and ventilation. 7 days after bagging, the material temperature can be basically stable. A few more thermometers should be placed in the stacks of bacteria bags up and down, not only depending on the temperature in the room or shed, but also on the temperature between the stacks of bacteria bags. Try to get germs at moderate temperature and keep the temperature at 18℃～22℃. When the temperature is high, the number of layers of the bacteria bag should be inverted, and when the temperature is low, the film should be covered to increase the temperature.

A medium-sized ear of corn provides more than 10% of our daily dietary fiber requirements. Rich dietary fiber can help the body to carry out a rapid metabolism function, but also can make a strong sense of satiety.
The same amount of corn is lower in calories than rice, contains natural rather than added sugar, and is high in fiber, which can help gastrointestinal digestion, and has more vitamins, so it is a good food worth eating more. However, there is a limit to what you eat, and the food that will not gain weight will make you fat if you eat too much, at least, it will not make you thin. It can only be said that relatively speaking, eating corn is much healthier than eating those high-calorie snacks, and it is not easy to gain weight.
Moreover, the large amount of natural vitamin E contained in fresh corn has the functions of promoting cell division, delaying cell aging, lowering serum cholesterol, preventing skin lesions, and reducing the symptoms of arteriosclerosis and brain function decline.
