Abstract:

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.
