摘　　要：为探究外源木质纤维素分解菌微生物复合系对食用菌菌糠堆肥腐熟化的腐熟进程,开发食用菌菌糠的肥料化处理技术,将食用菌菌糠与猪粪混合堆制。以未添加木质纤维分解菌复合系的堆肥为对照,探讨木质纤维分解菌复合系对食用菌菌糠堆肥化发酵特性与腐熟进程的影响。结果表明:添加木质纤维素分解菌复合系的堆体比不添加对照处理的堆体提前3d达到50℃;堆制结束时,添加木质纤维素分解菌复合系堆体中的纤维素、半纤维素和木质素的分解率分别为17.33%、7.26%和12.02%,为对照堆体的1.08、1.56和1.44倍;从C/N、pH、EC、萝卜种子发芽指数等综合评价,添加木质纤维分解菌复合系的堆肥时间为56d,而对照为66d,添加木质纤维素分解菌复合系缩短食用菌菌糠的腐熟进程达10d。In order to explore the decomposing process of exogenous lignocellulose degradation bacteria compound complex during edible fungus chaff composting,a fertilizer treatment technology of edible fungus chaff was developed.The edible fungus chaff and pig manure were mixed and composted.The compost without adding lignocellulosic bacteria compound complex was used as a control to explore the effect of lignocellulosic bacteria on the composting and fermentation characteristics and maturity of edible fungus chaff.The results showed:The stack with lignocellulose degradation bacteria compound system reached 50℃ 3 days earlier than the control treatment;At the end of composting,the decomposition rates of cellulose,hemicellulose,and lignin in the plant were respectively 17.33%,7.26% and 12.02%,which were 1.08,1.56 and 1.44 times of the control pile;From the comprehensive evaluation of C/N,pH,EC,and radish seed germination index,the composting time of the composite system of lignocellulosic bacteria was 56 dand that of control was 66 d.The composite system of lignocellulosic bacteria shortened the maturation process of edible fungi by 10 d.
