摘　　要：为研究不同堆肥条件对园林有机碳物质的影响,以复合菌剂的添加量、草木体积比(C/N)和翻堆次数为因素进行L9(34)正交实验设计,分析了堆肥过程中温度、总有机碳、木质素、纤维素、半纤维素、腐殖质及其组成的动态变化。结果表明:调节C/N比、翻推次数、添加复合菌剂可以加速木质素、纤维素等有机碳物质的降解,有利于在堆肥后期形成腐殖质类物质,提高腐熟程度,其中复合菌剂的添加量是影响总有机碳降解与腐殖质生成最重要的因素。在4%投菌量、2∶1草木体积比、1d翻1次堆的堆肥条件下,园林废弃物堆肥效果较好。In order to investigate the effects of different composting conditions on the degradation rate of organic garden carbon substances, the amount of bacteria, vegetation volume ratio（C/N） and turning frequency as the experimental factors, a compost test with an orthogonal experimental design L9（3^4） was conducted. The variation trends in temperature,total organic carbon concentrations, lignin, cellulose and hemi-cellulose contents, humus and compositing of compound fertilizer during composting were analysis. The results showed that adjustment of C/N ratio, turning frequency and the bacterial reagent benefited the degradation of organic garden carbon substances and the acceleration of maturity, and improved the compost quality. The addition of bacterial reagent was confirmed the most important factor affecting the degradation of organic garden carbon substances and the acceleration of maturity. The conditions of 4; addition of bacterial reagent,2 ： 1 vegetation volume ratio （C/N=30） and one day turns mow once was the best for the composting.
