中文摘要	为探寻促进干旱区城市防护绿地凋落物分解的途径,2007年10月下旬,分别采用青贮复合菌剂,秸秆腐熟剂和速腐增效剂3种微生物菌剂,对克拉玛依市区北郊防护绿地内的凋落物进行为期198 d的堆腐试验.结果表明:堆腐前期(0~30 d),微生物菌剂处理能够加快堆腐凋落物的分解,其中速腐增效剂处理与对照差异显著;随堆腐时间的延长,堆腐凋落物中N,P和Ca浓度均持续上升;试验结束时,各营养元素浓度均比初始值高14.2%~252.9%;在整个堆腐过程中,堆腐凋落物有机碳分解率持续升高,C/N值逐渐下降.添加微生物菌剂加快了堆腐凋落物的腐熟速度,提高了堆腐凋落物养分浓度,其中以秸秆腐熟剂处理效果最佳
英文摘要	In order to explore the ways for promoting litter decomposition in urban protective greenbelts of arid zone, litter falls were collected from the protective greenbelts in north suburb of Karamay, Xinjiang, and a composting experiment with the inoculation of three kinds of microbial agents,i.e., Qingzhu, Jiegan, and Sufu, was carried out for 198 days in late October 2007.At the early stage(0-30 d) of composing, inoculating microbial agents promoted the decomposition of the litter falls, and the effect of Sufu agent was significant, compared with CK.The N, P, and Ca concentrations in the composing litter falls increased persistently with time. By the end of the experiment, the nutrient concentrations in the composed litter falls were 14.2%-252.9% higher than their initial values. During the whole composing process, the decomposition rate of the litter falls organic C increased continuously, and the C/N ratio decreased gradually. It was suggested that inoculating microbial agents could accelerate the composting process, and increase the nutrient concentrations in composted litter falls. Among the three test microbial agents, Jiegan agent was the best one
