摘　　要：将具有高效纤维素降解能力和氨化作用的复合菌剂接种到以白酒丢糟为主要原料的堆肥中,通过测定堆积发酵过程各种发酵参数和成分变化,以研究复合菌剂对白酒丢糟高温好氧堆肥的影响。结果表明,在堆肥过程中,接菌堆体比对照(CK)提前2 d进入高温期,且高温期持续时间较对照长。堆肥结束,接菌堆体NH4+-N含量和总氮损失率分别比CK低28.3%、4.1%,而NO3--N含量、有机氮和总氮含量分别比CK高出22.2%、6.6%和7.9%。接菌处理的纤维素降解率、腐殖化指数(HI)和发芽指数(GI)分别比CK高18.7%、113.5%和8.6%。复合菌剂的添加促进了白酒丢糟堆肥化的进行,有效地提高了有机肥的品质。In the experiments, complex microbial inoculants made up of ammonifying bacteria and cellulose degradation fungi were applied in compost （mainly composed of waste spent grains）. The effects of complex microbial inoculants on high-temperature aerobic composting of waste spent grains were investigated by the measurement of the fermenting parameter of the composts. The results showed that, in the process of composting, a faster increase of temperature in the compost with inoculants （53.5 ℃in 5 days） than in CK pile without inoculants （50 ℃in 7 days） was observed;at the end of composting, the content of NH4＋-N and nitrogen loss in inoculants group was 28.3%and 4.1%lower than that in CK group, but the content of NO3-N, Org-N and TN in inoculants group were 22.2%, 6.6%, and 7.9%higher than that in CK group;cellulose degradation rate in inoculants group increased by 18.7%compared with that in CK group, in addition, humification index and germination index in inoculants group were 113.5%and 8.6%higher than that in CK group. In conclusion, the addition of complex microbial inoculants could accelerate the composting of waste spent grains and improve the quality of organic fertilizer.
