摘要
利用定制的环保型胶带开展胶带性能林间验证的结果表明,胶带阻隔持效期2.5～4.5 a,阻虫谱广,有益于天敌的生息繁殖.不同胶带宽度、捆绑部位和方式等对防治效果影响的试验表明,胶带产品最佳宽度10 cm,缠绕宽度以15～18 cm最佳,部位以胸径高度为宜,缠绕方式“上紧下松小裙环式”优于“两头紧直筒式”.中试后大面积应用证明,胶带阻隔法能有效降低6种主要食叶害虫的虫口密度和有虫株率.
The performance of the custom environment-friendly adhesive tape was verified in the forest. The result showed the obstruction effect of the tape lasted 2.5 -4.5 years; the spectrum of the insects obstructed was wide, which was benefit for the natural enemies. The experiment of the influence of tapes with different width as well as the best binding position and method on the control effect indicated the best width of tape was 10 cm and the best binding width 15-18 cm;the best binding position was at the height of the breast diameter; the binding method of ＂tight upper part and loose lower part （ skirt- shape） ring＂ was better. The result of large scale application after the pilot showed the method of ob- structing with adhesive tape could effectively decrease the population density and attacking rate of 6 species of main defoliators.
