前言凤尾菇在世界上许多地区已有普遍栽培。用稻草栽培凤尾菇,在理想的条件下,稻草基质转化为子实体的生物量约为11.2％,剩下15.3％的下脚稻草不能利用,其余73.5％的物质被分解为水和二氧化碳而损失。凤尾菇在稻草上的生长过程中,会使稻草中的成分,如碳水化合物、木质素、氨基酸、灰分等物质发生很大变化,这对以后作为一种饲料来说是重要的因素,经降解的纯稻草,是一种较好 Introduction Pleurotus ostreatus has been widely cultivated in many parts of the world. Under the ideal conditions, the biomass of rice straw substrates transformed into fruiting bodies is about 11.2%, while the remaining 15.3% of the bottom straw can not be utilized, while the remaining 73.5% of the materials are decomposed into water and carbon dioxide and the loss . The growth of Pleurotus ostreatus on the straw causes significant changes in the contents of the straw, such as carbohydrates, lignin, amino acids, ash, etc., which is an important factor for the future as a feed, Degraded pure straw, is a better
