Pollution-free production measures of Edible Fungi

First, improve the ecological environment. The cultivation shed should be located near the river, with smooth air and wide surroundings, at least 3000 meters away from livestock farms, breweries, living areas and hospitals; the site should take measures such as turning soil, tanning and irrigation to replace pesticide disinfection; the water quality of the source is clean and pollution-free, and mushroom spraying and flooding with sewage is strictly prohibited.

Second, advocate biological control. Plant fungicides and plant pesticides can be used in culture materials, such as perilla, woody oil plant rapeseed cake, etc. can be made into plant pesticides to kill insects and control mites. We can also use strong mushroom to inhibit insects, from strain selection, culture material ratio, stack fermentation, inoculation and mushroom management to strictly control all links, reduce diseases and insect pests, cultivate strong mushroom body, and enhance their own ability of disease resistance and resistance. In addition, we can also take specific mushroom rotation, intercropping, such as bamboo shoot has a strong fragrance, mosquitoes are afraid of smell, the use of mushroom, alternate rotation is also conducive to insect control.

Third, carry out physical prevention and control. Inoculation room, sterilization room, ultra-clean worktable, etc., using 30 watt ultraviolet lamp irradiation disinfection; can also use electronic ozone sterilizer disinfection and sterilization. The cultivation room uses black light to trap and kill insects such as mushroom mosquitoes, flies, leafhoppers and so on. The doors and windows of mushroom house (shed) are equipped with insect-proof net, screen window and so on.

Fourth, strict scientific use of drugs. Adhere to prevention-oriented, when determining the need for the use of chemical pesticides, we must choose high-efficiency, low-toxicity, low-residue agents. Such as trichlorfon, phoxim, propargite, Regent, methyl thiophanate, metalaxyl and so on. Medication should be carried out without mushroom production or after each batch of mushroom harvest, and pay attention to a small amount, local application, to prevent the expansion of pollution. It is strictly forbidden to spray pesticides in the long mushroom period, and it is forbidden to use all mercury pesticides such as methamidophos, methyl 1605, 1059, monocrotophos, isocarbophos, chlordimeform, omethoate, toxicol and other pesticides with high toxicity and high residues in the mushroom production process.
