摘要
根据柿树生理特点及柿蒂虫(Kakivoria flavofasciata)的发生规律,提出以垦复树盘、保墒施肥、合理修剪等营林措施为基础,实施“刮、诱、摘、喷”四项综合管理措施。通过三年推广应用3000ha,使虫果率由23.8%下降到1.1%,单株均产由51.05kg 提高到102.2kg,取得显著的经济效益。
According to the physiological characteristics of Kaki persi- mmon and the occurring regulations of Kakivoria flavofasciata,four measu- res of integrated pest management were proposed,which were based on the silviculture methods of digging and then putting soil around the Kaki pers- immon,applying fertilizer to preserve soil moisture and pruning the tree properly.The four measures were:scraping the old barks of the tree;capt- uring the pest with a straw put on the crotch and then burning it;taking away the damaged fruit and spraying the tree with insectiside.Throttgh three years' application to 3000ha,the rate of damaged fruit dropped from 23.8% to 1.1% with remarkable economic benefits.
