沼渣栽培鸡腿菇初探

Cultivation of Coprinus comatus Using Biogas Production Residue

以沼气发酵的废弃物沼渣为试材,部分代替鸡腿菇栽培常用栽培料中的玉米芯进行栽培试验,分别考察菌丝生长速度、生长周期、产量以及生物转化率。结果表明:以配方3(60%沼渣,20%玉米芯,13%麸皮,5%玉米粉,2%石膏,含水量63%~65%)栽培鸡腿菇,菌丝生长速度较快,生产周期短,产量和生物转化率最高,并且子实体中镉、汞、铅、砷的含量远低于国家对食用菌中重金属含量的要求,效果理想,可以在规模沼气发酵的地区推广、示范。

In order to analysis the effect of partly replacement corncob by biogas residue on Coprinuscomatus cultivation,Coprinus comatus cultivation experiment was performed to detect mycelium growth rate,growth cycle,yield and biotransformation rate.The results indicated that cultivation material formula 3（60% biogas residue,20%corncob,13% bran,5%corn power,2% gypsum and water 63%-65%）was optimum cultivation material for higher mycelium growth rate,shorter growth cycle,the highest production and highest biotransformation rate.In addition,content of heavy metals such as Cd,Hg,Pb,in fruiting body cultured on this medium was much lower than the national detection limit for heavy metals in edible fungi,so it was suitable for popularization and demonstration in the scale of biogas fermentation.
