摘　　要：为了解调节C/N比和添加复合菌剂对园林废弃物堆肥过程中有机物降解的动态变化和理化指标的影响,进行了不同处理措施的堆肥试验.结果表明,调节C/N比和添加复合菌剂有利于堆温的升高和有机质的分解,促进堆肥养分含量的增加,有利于全氮、有效氮及全钾的累积,但对全磷含量没有明显影响.表明调节C/N比和添加复合菌剂的处理措施比只调节C/N比更有利于堆肥的快速腐熟以及堆肥产品质量的提高.To disclose the effects of regulation of C/N ratio and adding the composite microbes on the dynamic changes of organic matter degradation and physicochemical indicators during green waste composting,different composting measures were investigated in the present paper.The results showed that proper adjustment of C/N ratio and addition of composite microbes were conducive to the temperature rising of compost and speeding up the organic matter decomposing and increased the nutrient contents and were in favor of the accumulation of total N、effective N and total K in compost with no significant effects on the the content of total P.These indicated that the adjustment of C/N ratio combining with adding the composite microbes was more helpful to speed up composting and improve compost quality than just only adjusting the C/N ratio.
