近年来,平菇生产发展很快,但不少平菇生产单位和专业大户,在袋栽平菇中都不同程度地出现了菌种质量问题。菌种已做常规出菇试验,二、三级菌种袋出菇正常,可是三级菌种接到栽培袋料中,在正常的栽培条件下却不发菌,或开始发菌正常,10天后菌丝逐渐消失,而造成大面积减产或绝收。

Strains have done routine fruiting test, two or three strains of bacteria fruiting bag normal, but the three strains of cultivated bags received in the normal cultivation conditions but not germs, or germs began normal, 10 Days after mycelium gradually disappear, resulting in large-scale production or income.
