福建省是我国毛竹主要产区 ,全省竹林面积 82 4万hm2 ,居全国第一。竹业是福建主要产业 ,是农村经济的重要组成 ,竹业发展的好坏关系到农村脱贫致富奔小康。福建省高度重视竹业发展 ,2 0 0 1年重点投资竹业开发二期示范工程 ,建设丰产示范基地。但近年来福建省毛竹林受到南京裂爪螨(Schizotetranychusnanjingensis)、竹缺爪螨 (Aponychuscorpuzae)严重危害 ,造成早期落叶 ,叶片焦黄似火烧状 ,竹笋产量大大降低 (张艳璇等 ,1 997a ;1 997b ;刘巧云等 ,2 0 0 0 ) ,制约了毛竹速生丰产示范基地建设。据调查 ,福建省毛竹害螨发生面积达 6 8万h…

STUDY ON PREVENTION OF SCHIZOTETRANYCHUS NANJINGENSIS

control methods were used for preventing and curing %Schizotetranychus nanjingensis%, they were bamboo cavity injection, bamboo cavity_injection+organic manure, pesticide+fertilizer, and organic manure. The results showed that the control method of bamboo cavity_injection was best, it was economical and effective, easy to operate and popularize. However its effective on turning?green of bamboo forest was not evident. The method of adding organic manure after bamboo cavity_injection promoted bamboo forest turning?green, but its cost was too high to be suitable to extension. The control method of pesticide and fertilizer had obvious effects on bamboo forest increasing production, continuous control, and turning?green of bamboo forest, it was suitable to extension in the distracts where the economic conditions were?good because of its higher cost. The method of adding organic manure clone was not?good for prevention since the control effect was worse.
