平菇是秋冬季栽培的主要菇类,采用一般栽培方法生物效率仅65～80％,如采用高产技术栽培生物效率可达150～200％。现将主要技术要诀介绍如下: (一)科学配料以棉壳为例,较理想的配方是:棉壳92％,铡碎稻草(或谷壳、甘蔗渣、茶籽壳)4％,过磷 Pleurotus ostreatus is the main mushroom cultivated in autumn and winter. The biological efficiency is only 65-80% using the general cultivation method, and the biological efficiency can be as high as 150-200%. The main technical tips are as follows: (A) of scientific ingredients Cottonseed, for example, the more ideal formula is: cotton shell 92%, broken straw (or chaff, bagasse, tea seed shell) 4%
