【摘要】 针对中国园林废弃物的堆肥现状，根据影响堆肥的诸多因素，探究不同处理下的最适堆肥方案。施加不同氮源和控制发酵剂含量，研究在堆肥过程中的pH、EC、全碳、全氮、全钾和全磷的动态变化。结果表明，在堆肥过程中各个处理均有利于促进堆肥进程。其中，pH和EC为先上升、再下降、后趋于平稳的趋势，T1处理pH和EC变化最为明显；全碳为持续下降趋势，T7处理的变化最为明显；全氮、全磷和全钾均为持续增长趋势，T1处理的变化最为明显。说明氮源对堆肥进程的影响大于发酵剂含量。更多还原

【Abstract】 In view of the composting status of landscape waste in China,the optimal composting scheme under different treatment was explored according to the factors affecting composting. Different nitrogen sources and starter contents were designed and applied to study the dynamic change characteristics of pH,EC,total carbon,total nitrogen,total potassium and total phosphorus in the process of composting. The results showed that each treatment was beneficial to the composting process. Among them,pH and EC increased first,then decreased,and then approached a stable trend. The changes of pH and EC were the most obvious in T1 treatment. Total carbon value decreased continuously,and the change of T7 treatment was the most obvious. The total nitrogen value,total phosphorus value and total potassium value all showed a continuously increasing trend,and the change of T1 treatment was the most obvious. It showed that the effect of nitrogen source on the composting process was greater than that of starter content.更多还原
