毛竹叶螨防治技术的研究

在室内试验的基础上，用多种药剂在林间开展竹腔注射和根施竹螨灵药肥防治毛竹叶螨，结果表明，两种防治方法对毛竹叶螨均有显著防治效果。竹腔注射５０％甲胺磷、４０％氧化乐果见效最快，３ｄ后害螨减退率达１００％。竹腔注射２０％杀灭菊酯、２０％快灵、５％抑太保和２０％灭扫利，１０ｄ后害螨减退率达８６．０％～９８．９％；３０ｄ后除灭扫利外，各处理害螨减退率达１００％。根施药肥１０ｄ后害螨减退率达９６．３％以上。从防治后受害毛竹林叶片长势、返青及新竹产量、质量上看，防治方法优先选择依次为综合治理、根施竹螨灵＋有机肥药肥、根施竹螨灵＋复合肥药肥、竹腔注射甲胺磷＋营养剂、根施竹螨灵＋尿素药肥、竹腔注射甲胺磷。
