摘要
在2001～2003年进行挂药试验和不同树种混交试验。现有d^(**)树种与杨树混交防治效果显著。挂d药试验在1～3a生林中每株挂1药,在5～6a生林中每株需挂3药,在5％的显著水平下防效显著。
Based on biodiversity, many tests such as pesticide hanging and mixed test among different tree species were done from 2000 to 2003. It showed that control by mixing with current tree species resulted in notable effect under the level of 5%. One package of d pesticide was necessary for every tree younger than 3 years, but three packages werc required for every tree under 5～6 years.
