近几年,随着食用菌的发展,棉壳货源紧缺,价格暴涨,严重影响了菇农的经济效益。采用作物秸杆做培养料在技术上虽有突破,但秸杆保温保水性差,生物效率一般为70%,经济效益较低。为降低成本,提高产量,我们自1992年起推广了复合料栽培平菇技术,并取得了显著效果,生物效率达到了200%,而生产成本降低50%,具体方法如下:一、最佳栽倍季节:复合料所含的养分多为大分子营养物质,需要在最适温度下才能被菌丝分解吸收利用,温度过低菌丝生长缓慢,吸收积累不到充足的养分,易出现前期生长良好,后期逐渐黄
In recent years, with the development of edible fungi, the shortage of cotton hulls and the soaring prices have seriously affected the economic benefits of mushroom farmers. Although the use of crop straw as a cultivation material in the technical breakthrough, but the straw insulation water retention is poor, the biological efficiency is generally 70%, lower economic efficiency. In order to reduce costs and increase production, we promoted the composite mushroom cultivation technology since 1992, and achieved remarkable results with a biological efficiency of 200% and a production cost reduction of 50%. The specific methods are as follows: Times the season: the compound contains nutrients are mostly macromolecular nutrients need to be under the optimum temperature to be mycelium decomposition absorption, hypothermia mycelium growth is slow, not absorb the accumulation of adequate nutrients, prone to pre-growth Good, later gradually yellow
