近几年来,平菇栽培面积不断扩大,特别是棉籽壳的生料栽培。随着生产的发展,杂菌为害日趋严重。我们从1981年开始在防空洞栽培平菇,第一年两季生长均良好,第二年两季均严重污染,污染率达80％,不能正常出菇。主要杂菌是根霉(Rhizopus sp.).青霉(Penicillium sp.)和木霉(Trichoderma sp.)。同时播种的稻草、麦秸、花生壳栽培块均未受污染,150平方尺的香菇也生长良好。为了查明原因,为生产提供予防杂菌为害的栽培措施,我们对防空洞棉籽壳栽培块上出现的3种主要杂菌进行了不同培养料浸提液洋菜培养
In recent years, mushroom cultivation area continues to expand, especially cottonseed shell raw material cultivation. With the development of production, the damage of miscellaneous bacteria is more and more serious. Since 1981, we cultivated Pleurotus ostreatus in air-raid shelters and grew well in both the first year and the second year with serious pollution in both seasons, with a pollution rate of 80%. The main bacteria are Rhizopus sp., Penicillium sp. And Trichoderma sp. At the same time, straw, wheat straw and peanut shell cultivated blocks were not polluted, and the 150-square-foot mushroom also grew well. In order to find out the reasons for the production of anti-bacterial culture to provide cultivation measures, we bomb shelled cottonseed shelled blocks appear three kinds of major bacteria were cultured culture extract liquid culture
