平菇是我国栽培范围广、面积大的主要食用菌,味道鲜美,营养丰富。近几年来,常常因菌种质量低劣和退化,造成产量低且极不稳定,甚至失收。为解决这个带有普遍性的问题,笔者采用平菇褶片贴附分离和孢子快速分离两种方法提纯菌种,均获得较高的栽培产量。这两种方法简便易行,污染率低, Pleurotus ostreatus is a major edible fungus with a wide range of cultivation and large area in China, with delicious taste and rich nutrition. In recent years, often due to poor quality and degradation of species, resulting in low yield and very unstable, or even lost. In order to solve this problem with universality, the author adopted Pleurotus ostreatus patch separation and rapid separation of spores two ways to purify the strains, all obtained higher cultivation yield. These two methods are simple and easy to use, the pollution rate is low,
