Green Mushroom should develop eight measures to prevent Diseases

Establish the concept of "large-scale prevention" of comprehensive prevention and control. The occurrence or even epidemic or outbreak of edible fungus diseases has its certain law of development, which is scientific and can not tolerate any carelessness. On the surface, the disease only appears in a certain production link, but the occurrence of the disease requires quite a lot of conditions. if a certain condition can not be met, the occurrence of the disease may be reduced, reduced, or even unable to occur. or even if it happens, it can't cause harm. Therefore, we can not only prevent or treat the disease, but should start from the source to the complete end of production, and the intermediate link can not be relaxed to completely eliminate the occurrence of the disease.

The selection of excellent virus-free bacteria is an effective measure to ensure that the bacteria do not carry any viruses and bacteria, ensure the health of the mycelium and improve the mycelium resistance. Virus-free strain is a strain cultivated by advanced cutting-edge separation and culture technology and through a four-cycle detoxification operation from hyphae to exploration base or fruiting body. In addition to maintaining the biological characteristics of the original strain, the virus-free strain does not carry any viruses and bacteria on its own, and it greatly improves its adaptability to external conditions and stress resistance due to the artificial regulation of matrix and temperature in the process of detoxification. This is the second advantage of virus-free bacteria. At the same time, the detoxification process is also a domestication process under adverse conditions, which makes the strain grow in the relative environment from the very beginning, and naturally enhance resistance and disease resistance in the process of gradual growth and development, which is the third advantage of virus-free bacteria. The comprehensive results showed that the comprehensive incidence rate of virus-free bacteria decreased by more than 60%, which laid a good foundation for cultivation and production.

Strict disinfection in mushroom shed and cultivation environment is the main means to eliminate residual virus bacteria. The cultivation of mushroom shed, especially the old mushroom shed, because of the disease-prone conditions formed in long-term cultivation and the remaining hyphae and spores of diseases in cultivation, it is very easy to form harm when it is recultivated, which is the main reason why the yield of old mushroom shed cultivation is low and the disease is serious. First of all, clean up the environment around the mushroom shed, such as dung piles, grass piles, garbage, etc., remove weeds, and spray about 500 times of carbendazim germicidal drugs many times to thoroughly clean the environment. Secondly, the old mushroom shed should be scraped off the wall skin, when there are conditions, the surface can be eradicated about 1 cm, after the exchange of 50 times mushroom disease king solution, carpet spraying on the shed, even if the wall, corners, columns, ventilation holes, etc., should also be sprayed, without leaving any dead corner, remove the cover on the greenhouse film, so that it can be used in about 5 to 7 days. This measure can thoroughly kill viruses and pathogens in the shed, and its basic principle is that the king of mushroom dispelling disease is a compound drug of bactericidal and bacteriostatic agents, which has a strong killing effect on viruses and bacteria. Can also use 10 times strong glutaraldehyde solution, 200 times Venus disinfectant, although the irritation of formaldehyde in production, but the preparation of multi-nail solution spraying germicidal effect is also very good, generally according to carbendazim: formaldehyde: water for the ratio of 1: 2 to 100, if the disease is more serious in the last season, the drug concentration can be increased appropriately. Finally, for the mushroom shed with serious primary disease, the upper shelf rod and plastic film can be removed, straw weeds are piled in the shed, burning is ignited, grass ash is turned into the soil layer, the pole is covered with film again, and the effect is very good. This method uses the combination of physical and chemical methods for sterilization, which is relatively thorough. However, the specific operation should choose windless weather, and be equipped with appropriate fire fighting means, mushroom sheds concentrated areas should be unified action, in addition, mushroom sheds near villages, buildings should not use this method, so as to avoid fire danger.

The effective treatment of soil covering material is an important link to prevent the disease from entering the shed. For the sterilization treatment of soil-covered materials, we tend to use the methods of exposure, medicine and stuffy heap. after selecting soil-covering materials, we will expose them on the hardened ground, and with the turning, the soil particles will be kept below 0.5 cm in size, mostly in the form of powder. prepare 100 times mushroom disease king solution while spraying and mixing, repeated 2 times, covered with film after the construction of the shed, the effect is excellent.

The handling of the base material should be strict, which is the key link to ensure that "enter the shed without disease". This stage includes exposure treatment of dry materials, uniformity of fermentation treatment, standardization of bagging and sowing, clinker inoculation, culture and sterilization of the environment. After the bacteria are sent, the mushroom dispelling king solution of 200 times should be prepared before entering the shed, put it in large pots and other containers, soak the bag one by one and then enter the shed.

Germicidal and bacteriostatic drugs are often sprayed in the mushroom shed, which is the main means of prevention in the process of mushroom production management. After the bacteria bag is put into the shed or the base material is sown in the shed, drugs should be sprayed frequently in order to prevent diseases. Because the greenhouse is relatively airtight, the ventilation is relatively poor, and the air humidity is high and the temperature is relatively constant, it can induce the occurrence of diseases.

Nip the disease in the bud. At the beginning, it is the main measure to prevent the disease from propagating in large numbers. For the initial disease, we should thoroughly deal with the three-dimensional cultivation of the bacterial bag, clean it out of the shed together with the diseased bacterial bag, and bury it deeply after soaking the medicine. When the quantity is large, the pile can be stuffed after spraying, or sprinkled with lime powder, the method is: after the pile is built, the material soil is sealed with thin mud to make it naturally ferment, produce heat, and kill germs. For soil-covered cultivation, the scope of the disease area should be expanded and the base materials should be controlled to the end and cleaned out of the shed.

Effective prevention and control of pests is also one of the important measures to control diseases. Most pests often carry a large number of germs, once in the shed, they can form a "source of disease", spread everywhere, form and spread, so in the prevention and control of diseases, the control and killing of insect pests must not be ignored. The main measures are as follows: clean up the external environment, spray high-efficiency and low-toxic drugs to control the source of insects; sprinkle more than 2 meters of lime aisle at the door of the mushroom shed to prevent reptiles from entering; vents and doorways are sealed with anti-insect nets to prevent flying insects from entering; after pests are found, poison bait is adopted, and the effect is better. For mushrooms, mosquitoes and flies can be killed by spraying and killing spirits during the intermittent period of mushroom production; it can also be entrapped with sweet and sour liquid, which can be killed according to the ratio of high liquor: sugar: vinegar: water is 1: 2: 3: 4, add 3-4 drops of ddv solution in the mode of production, put it in a container, and the adults can be killed.
