In the cultivation of mushrooms, no matter it is cultivated with raw material or clinker, no matter it is in bed or in bags, it will occur to a certain degree, such as green mold, penicillium, Aspergillus, Rhizopus, and white mold. The high temperature season is particularly serious, and many producers are seriously troubled. Once bacterial contamination of mushrooms occurs, it is difficult to remove the bacteria by simply relying on the use of bactericidal drugs, and increasing the cost may even lead to the occurrence of phytotoxicity. According to the characteristics of various bacteria aerobic, high temperature and high humidity, the author adopted methods such as covering sediment or wet soil to isolate the oxygen supply of the bacteria, so that they gradually disappeared in the absence of oxygen, and mushroom mycelium could grow rapidly. The swallowing of bacteria, control effect is very significant. The introduction is as follows, readers may wish to try. Mushroom cultivation when the sudden high temperature (natural temperature or temperature rise), it is easy to cause contamination of bacteria. In the case of sporadic germs on the surface of the material, it can be effectively controlled by smearing with concentrated lime slurry or covering the affected area. If bacteria are generated in large areas, the most effective method is to excavate river sediment or yellow silt below 30 cm from the surface. Sand and soil is free of pests and diseases. After breaking, add 2% lime powder and mix evenly. Remove the thin film and cover 2-3 cm thick sediment on the surface of the material surface. Coverage area is slightly larger than the pollution area. tight. If the material surface is heavily contaminated, the entire bed surface should be covered. After the end, wash the film and cover it again to resume normal management. After a few days, the mycelia can resume growth, and the mycelia in the sediment will soon be covered with it, which will not only have no effect on the yield of the oyster mushroom, but also have a certain effect on yield increase. When germs appear in bagged mushrooms, they should be picked out by a contaminated bag of bacteria and a high-pitched pit should be excavated to a depth of about 60 cm (the size of the pit depends on the number of contaminating bags, and attention should be paid to the inside of the pit. Can not have stagnant water), the bacteria bag contaminated site down into the pit and placed (do not take off the bag), 5 cm spacing to isolate the soil, and cover the bag 25-30 cm thick wet fine soil or wet sand, After 15-20 days of cultivation, all the contaminated bacteria bags will return to normal, and all the hyphae will grow well. They will be moved to the mushroom farm to open bags and produce mushrooms, and the rate of mushroom production will not be affected. If the groundwater level is too high to dig deep pits, only about 20 centimeters of shallow pits may be excavated. After the fungus bag is placed on the surface, 20-25 centimeters thick wet soil or silt is covered, and the effect is the same. Regardless of the method used, rain should cover the film and open a drainage ditch around it to ensure that no water can accumulate in the pit. China Agricultural Network Editor
