人工林虫害精确防治试验与分析

Study on the Accurate Control Techniques of Pest in Plantation Forest

分析了我国人工林虫害严重的原因,提出了人工林虫害“精确防治”的概念,着重探讨这一技术体系中对环境影响最小的精确打击方法———选择性施药技术,集中杀灭害虫,实现最佳防治效果。同时结合徐州地区多年进行的虫害防治试验和推广实践,阐述树木注射施药技术的原理、特点及其防治技术。

The causes leading to the occurrence of plantation insect pest were analyzed,and the concept of accurate control of plantation insect pest was put forward,especially the selective pesticide application technology which affected least to the environment in this technique system was discussed. It killed the insect pest strongly and achieved the best control result. Based on the control experiments and popularized practice in Xuzhou area,the machanism, property and method of trunk-injection pesticide application technique were expounded in detail.
