摘要
目的研究不同微生物菌剂对有机废弃物堆肥发酵的影响，为筛选堆肥效果更好的优势菌种提供依据．方法通过选取3种代表性微生物菌剂进行有机废弃物堆肥试验，并对堆肥温度、含水率、pH值、C／N、养分组成、种子发芽指数及粪大肠菌群数等指标进行分析，最后综合评判供试菌剂的性价比．结果试验结果表明，在初始堆肥条件相同的情况下菌剂3应用于有机废弃物堆肥发酵起温快，持续温度高，脱水快且稳定，最终含水率较低，DH值保持在适宜微生物生长的范围，一次发酵后期C／N更接近（20～35）：1的理想范围，磷钾没有流失和富集，氮损失较大，种子发芽指数高，单位粪大肠菌群数小，综合判定菌剂3的堆肥效果相对较好．结论菌剂3对有机废弃物堆肥的发酵效果优于其它菌剂．
The effect of three typical microorganisms was researched on how they may change the biological and chemical parameters of the compost. Significant correlations were proved among temperature, water content rate, pH, C/N, GI, Nutrient components and the number of coliform bacteria. The results showed that Inocula 3 could obviously increase fermentation temperature during early period of composting, reduce the effects of compost materials on seed germination index, and accelerate dehydration of compost materials and the maturity of composting. Among the microorganism agents studied, microorganism agents of Inocula 3 was better.
