当前栽培黑木耳,最突出的一个问题是,耳棒杂菌多,木耳害虫多,制菌和代料栽培污染多,往往给生产造成不应有的损失。造成耳棒杂菌多的原因,主要是耳场、耳棒和使用工具消毒不严,耳场通风不良,长时期的郁闷空气造成的。木耳的害虫,主要是冬季对虫卵消灭不彻底和春夏防治不及时。制菌和代料栽培的污染问题,主要是分离的标本带菌,培养基消毒不彻底,引种室的箱和所用工具消毒不良,或引种室、箱封闭不严。中途带进杂菌,使用了被污染的原种和母种,操作人员的手和工作服、帽消毒不好等,都 Currently cultivated black fungus, one of the most prominent problem is that more ears and miscellaneous bacteria, fungus pests and more bacteria and substituting the cultivation of pollution, often to the production of undue losses. Miscellaneous causes of earbuds and more, mainly the ear field, ear sticks and the use of tools lax disinfection, poor ventilation in the ear field, a long period of depressed air caused. Agaric pests, mainly in the winter to eliminate insects and insects is not complete prevention and treatment in time. Bacteria and substituting cultivation of pollution problems, mainly with the separation of specimens carrying bacteria, medium disinfection is not complete, the introduction of the chamber box and the tools used to disinfect poor, or the introduction of the room, the box closed lax. Halfway into the bacteria, the use of contaminated species and mother species, the operator’s hand and work clothes, cap disinfection is not good, etc.
