平菇生产是我县近年来发展较快的一项农村副业,一般用棉籽壳生料栽培,而我县糠醛生产对棉籽壳需求量很大(占总产的80～85%),为了解决两者争夺原料之矛盾,笔者从87年元月开始用县化工厂生产糠醛的下脚料糠醛渣进行代料栽培平菇试验,取得了良好效果,现将试验情况简报如下:(一)培养料配方在栽培前首先要对糠醛渣进行处理。选新鲜的糠(?)渣(由于内含低浓度硫酸久存易碳化),置水中浸泡8～12小时,捞出后放入尼龙纱(孔径0.2cm)反复冲淋至pH 为5.5～7.0。
Pleurotus ostreatus production is a rapid development in our county in recent years, a rural sideline, generally cottonseed shell raw material cultivation, and my county furfural production of cottonseed shells in great demand (accounting for 80 to 85% of total production), in order to solve The two compete for the contradiction between raw materials, the author started from January 1987 with the county chemical plant furfural waste furfural generation substituting mushroom cultivation test, and achieved good results, the test is now briefed as follows: (a) culture materials The formula must be treated furfural residue before planting. Picked fresh bran (?) Residue (due to the low concentration of sulfuric acid containing a long easy to carbonization), soaked in water 8 to 12 hours, remove the nylon yarn into the (aperture 0.2cm) repeated shower until the pH of 5.5 to 7.0 .
