一、杂菌与防治1,常见杂菌:①长毛菌:接种后料面长出疏松的灰白色毛霉和根霉,统称“长毛菌”。毛霉菌丝初为白色,衰老后变为淡黄色,菌丛可高达3——12厘米,能在基质上广泛蔓延,污染菌种和培养料。根霉菌初期也为白色,老熟后呈灰黑色或黑褐色。“长毛菌”一般在培养初期出现,生长极为迅速。并与黑木耳争夺养料和水份,分泌有机酸和毒素,影响木耳菌丝生长。易在高温、高湿,通风不良的情况下发生和发展。②绿霉菌:有很多种,如绿色木霉、康宁木霉和多孢木霉等,生产上统称绿霉
First, the bacteria and control 1, common bacteria: ① hairy bacteria: after inoculation material surface grow loose gray Mucor and Rhizopus, collectively referred to as “hairy bacteria.” Mucor mycelia early white, pale yellow after aging, flora can be as high as 3 - 12 cm, can be widely spread on the substrate, the pollution of bacteria and culture materials. Rhizopus initial white, mature gray or dark brown. “Hairy bacteria” generally appear early in the culture, growth is extremely rapid. And fight against black fungus nourishment and moisture, secretion of organic acids and toxins, mycelium growth. Easy in high temperature, high humidity, poor ventilation occurs and development. ② green mold: There are many species, such as Trichoderma viride, Trichoderma koningii and Trichoderma miltiorrhizae, the production are collectively referred to as green mold
