空气、沙土、尘埃、各种生物及物体表面或孔隙内均存在大量细菌、真菌孢子,同时栽培食用菌的原料、水分、空间等也同样存在着大量的微生物,其中大部分对食用菌生产是有害的,可导致菌种、栽培材料和培养环境的污染。一旦染上杂菌,杂菌即与食用菌争夺营养、空间、水分和氧气,侵害健康的子实体,使其发生畸形,降低商品的价值。因此防 A large number of bacteria and fungal spores are present in the surface of air, sand, dust, various organisms and objects or spores, and a large number of microorganisms are also present in raw materials, water and space for edible mushroom cultivation, most of which are for edible mushroom production Harmful, can lead to bacteria, cultivation materials and culture environment pollution. Once contaminated with bacteria, bacteria and edible mushrooms compete for nutrition, space, moisture and oxygen, violations of healthy fruiting bodies, make it deformed, reducing the value of the commodity. So anti
