sowing. According to the morning and evening of the sowing season and the thickness of the material, the amount of sowing can be controlled flexibly, generally 1.5 to 2.5 bottles per square meter. Before sowing, all the tools must be thoroughly disinfected with potassium permanganate solution, while the culture material should be shaken and leveled, with a thickness of 20-25?, and sown in real time according to local climatic conditions. Heze, Jining, Liaocheng, etc. in Shandong Province The general planting time in the city in August, Shanxi Province, Taiyuan, Luliang and other places generally in late August early September. In the actual operation, the live broadcast method is generally adopted, that is, all the bacteria are sprinkled on the surface, this method is simple and quick, and the mycelium can seal the material surface in a few days, and the bacteria are not easy to invade. After sowing, lightly compacted with a poisoned wood board, and then covered with a film. If the material is slightly damp, it can also cover newspapers or other sterilized paper. Sealed doors and windows, enter the bacteria period.
Fungus. During germination, the water droplets adhering to the film are often shaken down to the ground. The mycelium germination can be peeled off after 7-10 days of germination. If the surface of the bacteria or the covering space is too high, the film can be uncovered. .
1. In the fungus period, we must constantly observe the growth of hyphae and the speed of the hyphae to eat, and find problems in a timely manner so as not to delay the best period of treatment, resulting in the spread of pests and bacteria, thereby reducing the yield. If the culture material is too dry or too wet, the hyphae will not be eaten or removed. Overdrying can spray water into the air to increase the humidity of the air. For example, if the culture material is too wet, it can be used to fight back the brazing or digging materials and increase ventilation.
2. Always observe the changes in the temperature of the material. If the material temperature is higher than 30°C, measures should be taken to make holes and compact the surface of the material. Ventilate at night. It is also necessary to prevent the ammonia in the material from being too heavy and to inhibit the normal growth of mycelium. If the ammonia content in the material is heavy, it is necessary to adopt brazing and top loosening measures for the cultivation of materials, as well as spray 2% formaldehyde solution on the ground wall aisles, etc. . If the ammonia content in the material is indeed too heavy and the shrinkage of the hyphae has been caused, it will not be saved. At this time, the material should be re-steamed again and replanted.
3. It is necessary to promptly deal with the problem of miscellaneous insects and insecticides. In case of harm, it must not be taken carelessly. It must be treated promptly and fumigated with drugs if necessary. This requires us to pay attention to the quality of the cultivation materials after the completion of the pre- and post-fermentation, identify problems and take timely measures to avoid the occurrence of such problems after sowing, and delay the best time for treatment.
4. Germ fungus 1-5 days, the main function of heat preservation and moisturizing, under the condition of normal germination mycelium is not ventilated or less ventilated, promote mycelium germination and colonization as soon as possible, block material surface. After 6-10 days of germination, the mycelium has basically covered. With the depth of the hyphae, the amount of ventilation is gradually increased. Germ fungus 11-18 days, when the hyphae to feed 1/2 of the material layer must be promptly played brazing ventilation, while increasing ventilation, increase the oxygen content of the material. When the mycelium eats more than two-thirds of the material layer, prepare to cover the soil (it is best to cover the entire material layer).
