First, to improve the ecological environment Cultivation of sheds to be selected in the vicinity of the river, air smooth, wide around, away from the livestock farms, brewing plants, living areas, hospitals at least 3,000 meters away; venues to take over soil, drying, irrigation and other measures to replace Disinfection of pesticides; Clean water source without pollution, Spent sewage mushroom, soaked in water. Second, promote the biological control culture material configuration can be used plant anti-mold agents and plant pesticides, such as Chinese herbal medicine perilla, woody oil plant rapeseed cake, etc. can be made of plant pesticides, insecticide, lice. You can also use the strong mushroom inhibitory insects, from strain selection, culture material ratio, batch fermentation, inoculation, mushroom management all aspects of strict management, reduce pests and diseases, enhance mushroom body, enhance their resistance to disease ability. In addition, specific mushroom rotations and intercropping can also be adopted. For example, bamboo crickets have a strong fragrance. Mosquitoes are daunting. Rotating with mushrooms and alfalfa alternately is also beneficial to pest control. Third, the implementation of physical control inoculation room, bacteria room, clean bench, etc., using a 30-watt ultraviolet light irradiation sterilization; can also be used electronic ozone sterilizer sterilization. The cultivation room uses black light to lure insects such as mosquitoes, flies and leafhoppers. Mushroom (shed) doors and windows installed insect nets, screens and so on. Fourth, rigorous use of scientific drugs should be the mainstay of prevention. When it is determined that chemical pesticides are needed, they must use high-efficiency, low-toxic, low-residue pharmaceuticals. Such as trichlorfon, phoxim, konjac, fipronil, thiophanate-methyl, metalaxyl and others. Medication should be carried out without mushrooming or after harvesting each batch of mushrooms, and attention should be paid to small amount and local application to prevent the increase of pollution. It is forbidden to spray pesticides during the long mushroom period, and it is forbidden to use methamidophos, methyl 1605, 1059, monocrotophos, isocarbophos, insecticidal locust, omethoate, phenolic meth Pesticides and other highly toxic, high residue pesticides. V. Conformity of product processing standards Edible fungus products often cause sulphur content exceeding the standard due to the processing process. Therefore, it is necessary to fully promote the dehydration and drying of precision machinery. Mushroom packaging must meet the national health standards: GB7096-86 health standards for edible fungi, GB7097-86 health standards for edible fungi and GB9691-88 food packaging hygiene standards.
