摘　　要：为了减少大量园林废弃物经过燃烧、填埋等对环境产生的危害,利用好氧堆肥技术,加快堆腐速度,变废为宝,实现资源有效化、无害化、循环化利用,适宜的堆肥菌剂的筛选尤其重要.在园林废弃物数量调查和不同材料C/N比测定的基础上,将9种园林绿化废弃物混合为主要材料,分别添加5种不同的微生物复合菌剂进行好氧堆肥试验,分析了堆肥过程中堆体温度、氮含量的变化,以筛选出园林废弃物堆肥的适宜菌剂.结果表明:不同绿篱植物平均年修剪量达3.10 kg/m2;添加微生物复合菌剂,可以缩短堆肥时间,减少园林废弃物中氮的损失量;不同菌剂对园林废弃物堆肥进程以及堆肥初产品N含量的影响各有不同.在低温季节,快速堆肥可采选用T2、T4,而在高温季节,为获得较高N含量堆肥初产品,T2、T5将是好的选择.T2则兼有腐熟快、N含量高的优点.In this study,the composting experiment was carried out by outdoor high-temperature aerobic compost technical using landscaping wastes as composting material,which five kinds of microbe fungus were added as five different treatments in order to screen the most effective microbe fungus which can be used in the composting treatment of landscaping wastes. The quantity of annals trimming of nine kinds of landscaping plants,C /N,changes of temperature during composting,the N content by the end of composting were analyzed,compared with blank CK which did not add any microbe fungus. The results showed that the annual amount of trimming waste is up to 3. 10 kg/m2 on the average. First of all,adding microbe fungus would promote the process of composting of landscaping waste. Microbe fungus of T2 and T4 are beneficial to raise the initial temperature,which can advance and prolong the period of high temperature,shorten the composting period,and microbe fungus of T2 and T5 are beneficial to accumulate the total N.
