近年来,我市平菇生产发展迅速,但多数产量不高,品质欠佳。究其主要原因是所用的菌种多数从外地引进,菌种代数不清,加上引种后盲目转管扩大,致使菌种退化严重,纯度降低,适应性变差。为此,我们从1993年起,着手对平菇引进品种进行提纯与复壮试验,取得了明显的效果。 In recent years, the rapid development of mushroom production in our city, but most of the yield is not high, poor quality. The main reason is that most of the strains used were introduced from the field, the strain algebraic unclear, coupled with the blind after the introduction of tube expansion, resulting in severe degeneration of bacteria, reduced purity, poor adaptability. To this end, we started from 1993 onwards, the introduction of species of Pleurotus purification and rejuvenation test, and achieved significant results.
