摘要
本研究根据园林植物立地环境和污染程度,将园林生态系区分为3个子系统,分别对其主要食叶害虫进行综合治理。结果表明,实施综合治理后,农药使用次数和投放总量分别减少86.6％和89.7％,8种主要食叶害虫均得到有效控制。
Based on the micro - environment of the site of ornamental plants and its pollution ,the city forestry ecology system is divided into three subsystems and integrated pest management (IPM) was practiced on the leafeating insects in each subsystem. As a result , the number of insecticide application was reduced by 86. 6% and the input for insecticides by 89. 7%. Eight species of major leafeating pests were brought under effective control.
