Establish the concept of “big prevention and control†for comprehensive prevention and control. The occurrence or even the outbreak or the outbreak of edible fungus disease has its own development law. The law is science and it cannot tolerate sloppy. On the surface, the disease only occurs in a certain production process, but the occurrence of the disease requires a considerable number of conditions. If a certain condition cannot be met, the occurrence of the disease may be reduced, reduced or even impossible, or even if it occurs. Can not form a hazard. Therefore, we should not only prevent or treat diseases in the event of disease, but should start from the source, until the end of production, the intermediate link can not be a little relaxed to completely eliminate the occurrence of disease. The selection of excellent detoxification strains is an effective measure to ensure that strains do not contain any virus pathogens, ensure hyphae robustness, and increase mycelial resistance. The virus-free strains adopt advanced cutting-edge separation and culture technology and undergo the four-cycle detoxification operation of the mycelia to the exploration base or fruit body to cultivate the strains. In addition to maintaining the biological characteristics of the original strains, the virus-free strains do not carry any virus pathogens themselves, which is one of their advantages; due to artificial regulation of the matrix and temperature in the process of detoxification, it also greatly improves the adaptability to external conditions. And stress resistance, which is the second advantage of the detoxification strains; the detoxification process is also a domestication process under harsh conditions, so that the strains grow in the relative environment from the very beginning, in the process of gradual growth and development. In nature, it enhances resistance and improves disease resistance, which is the third advantage of the detoxification strains. Comprehensive results show that the overall incidence of the use of detoxified strains decreased by more than 60%, thus laying a good foundation for cultivation. The strict sterilization of mushroom sheds and cultivated environments is the main means to eliminate residual virus pathogens. Cultivation mushroom sheds, especially old mushroom sheds, can easily form hazards when they are cultivated again due to the proneness of long-term cultivation and the remaining mycelium and spores of diseases during cultivation. This is why cultivation of old mushroom sheds has low yield and disease. The main reason is serious. First of all, clean the surrounding environment of mushroom sheds, such as dung, haystacks, garbage, etc., should be cleaned up, weeds should be removed, and sterilizing drugs of 500-times carbendazim should be sprayed several times to thoroughly clean the environment. Secondly, the old mushroom shed should be scraped to remove the wall covering. When conditions permit, the surface can be eradicated by about 1 cm. After the foundation, 50 times the mushroom worm disease solution can be countered. The carpet can be sprayed on the shed, even if the wall or the corner , Columns, ventilation holes, etc. should also be sprayed with drugs, leaving no dead ends, to remove the cover film on the film, so that exposure, about 5 to 7 days to start. This measure can completely kill the shed virus and pathogenic bacteria. The basic principle is: mushroom scorpion disease king is a compound drug of bactericidal and bacteriostatic agent, and it has strong killing power to virus germs. Can also be used 10 times stronger glutaraldehyde solution, 200 times Venus disinfectant, production in spite of the irritation of formaldehyde is relatively large, but the preparation of multi-solution spray sterilization effect is also very good, generally according to carbendazim: formaldehyde: The ratio of water is 1:2:100. If the disease is severe during the last season, the concentration of the drug can be increased. Finally, for the mushroom shed with severe primary disease, the upper struts, plastic membranes, etc. can be dismantled. Straw weeds are piled in the shed, ignited and burned, the straw ash is turned into the soil layer, and the rods are covered and membranes are applied again. Spraying is very effective. The method uses physico-chemical combination to sterilize, which is relatively thorough. However, in the specific operation, windless weather should be selected, and appropriate fire-fighting measures should be provided. The centralized area of ​​the mushroom shed should be operated in a unified manner. In addition, the mushroom shed near the village or building should not use this method to avoid fire hazards. Effective treatment of earth-covered materials is an important part of preventing disease from entering the shed. For the sterilizing treatment of earth-covered materials, we tend to insolation, drugs, and stuffy stuffing methods. After we choose the earth-covered material, we expose the surface to hardened ground. With turning, the particles are kept below 0.5 cm in size, mostly in powder form. One hundred times of the mushroom scorpion sinus disease solution was sprayed and mixed, and repeated twice. After the shed was built, the film was piled up and boring. The effect was excellent. The handling of the base material must be strict. This is the key to ensuring that “without sickness into the shedâ€. This stage includes the drying treatment of dry materials, the uniformity of the leavening treatment, the standardization of the bagging and sowing, the inoculation of the clinker, and the clean and sterilizing of the culture environment. After the fungus is completed, 200 times of the mushroom scorpion sickness king solution should be prepared before the bacterium bag enters the shed. The saccharomyces should be filled in large pots and other containers. The bacterium bags should be washed once and then put into the shed. Mushroom shed is often sprayed with bactericidal antibacterial drugs, is the main prevention measures in the process of mushroom management. After the bacteria bags enter the shed or the base material is sown into the shed, the drugs should be sprayed regularly to prevent disease. As the shed is relatively closed, ventilation is relatively poor, coupled with high humidity and relatively constant temperature, it can induce disease. The disease is destroyed in the bud. At the time of its initial development, it was the main measure to prevent the disease from multiplying and forming harm. For the first-time disease, it should be treated thoroughly and the three-dimensional cultivation of the bag should be carried out. When the number is large, it can be used for heaping boredom after spraying, or it can be stuffed and stuffed with lime powder. The method is: After the pile is built, the soil is piled with a thin mud to allow the natural fermentation, heat production, and killing. Dead bacteria. For the soil-covered cultivation, the scope of the ward should be expanded together with the base material in the end to clear the shed. Effectively preventing and killing pests is also one of the important measures for disease prevention and control. Most pests often carry a large number of pathogens. Once they enter the shed, they can form "sources of disease", spread them everywhere, and form sprawl. Therefore, in the prevention and treatment of diseases, the control and killing of insect pests must not be ignored. The main measures include: cleaning up the external environment, spraying highly effective and low-toxic drugs to control the pests, and spraying the limestone aisle at the entrance of the mushroom shed more than 2 meters to prevent reptiles from entering; vents and gates to prevent pests from entering. After the detection of insect pests, bait trapping was adopted and the effect was good. For mushrooms, mosquitoes and flies can be killed by spraying and killing spirits during the interval of fruiting; also can be used to seduce and kill sweet and sour liquids, according to the height of white wine: sugar: vinegar: the ratio of water is 1:2:3:4. After it is good, add 3 to 4 drops of DDV solution to the production method and collect it in the container.
