平菇抗杂菌能力强,生产率高,可以开放栽培,是我国发展最快,产量最高的菇类。但是,从生产角度来看,平菇的高产特性尚未得到充分发挥。主要表现:①发菌过程中霉菌污染,特别是连年栽培的场所更严重;②管理不当,部分栽培块前期不出菇,总的生产率降低;③出菇后 Mushroom anti-bacterial ability, high productivity, open cultivation, is China’s fastest growing, highest yield mushrooms.

The main manifestations are as follows: ① mildew in germination process is more serious, especially in successive years; ② improper management, some mushrooms do not produce mushrooms in the early stage and the total productivity is reduced; ③ after fruiting
