摘要
为了保证良好的景观效果,根据叶螨发生程度和叶片受害程度,确定古松、柏上叶螨类防治指标为20头/20cm枝段。并选取常用的六种杀虫杀螨剂对古松和古柏上的叶螨进行化学防治,其中以灭虫灵、立打螨等效果最为显著。
To maintain good scenic effects,the scenic thresholds to mite were determined as 20 head/20 cm branch on antique pine and cypress according to the population density of mite and damaged extent to the tree. In the field trial, six insecticides were used for the control of mites.The results showed that and had better effects.
