食用菌杂菌已达100余种,最常见且危害较严重的杂菌主要有木霉、链孢霉、毛霉、曲霉、青霉、细菌等20多种。1、木霉木霉俗称绿霉,几乎能为害所有的食用菌,其对食用菌的为害表现为:污染培养料,与食用菌争夺营养和空间;分泌霉素杀伤、杀死寄主;木霉菌丝接触到寄主菌丝时将寄主菌丝缠绕切断。采用的防治方法:培养室、栽培场所应保持低温,空气相对湿度控制在85%左右,并保持清洁卫生,通风良好。一旦发生木霉为害,要立即通风降
Edible fungi has reached more than 100 kinds of bacteria, the most common and more harmful bacteria are Trichoderma, Neurospora, Mucor, Aspergillus, Penicillium, bacteria and more than 20 kinds. 1 Trichoderma viride commonly known as mold, almost all harmful to the edible fungi, its harmful effects on edible fungi: pollution of culture materials, and edible fungi for nutrition and space; kill the killer, kill the host; Trichoderma The host filament is wound and cut off when the filament contacts the host mycelium. Control methods used: training room, cultivation sites should be kept at a low temperature, air relative humidity control at about 85%, and maintain clean, well-ventilated. In the event of Trichoderma damage, ventilation should be immediately reduced
