树木注射施药机械与使用技术进展

Advances in the Technique of Tree Injecting With Chemicals

树木注射施药／施肥技术，经过国内外７０多年的不断研究正在取得突破性进展：施药器械已完成了由无压或低压、低浓度、大容量、低工效机型向高压、高浓度、低容量、高工效机型的转换；注射物扩大到了杀虫剂、杀菌剂、微肥、植物生长调节剂各个方面，并且取得了比喷雾、土施等常规技术好的使用效果；与环境的关系方面，证明是化学防治与天敌利用、生态保护相互和谐的现实的有效途径。不足之处是机械自动化程度低，劳动强度偏大，杀菌剂的应用试验有待深入。

Abstract The advances in the techniques of tree injecting with various kinds of chemicals at home and abroad were introduced in detail. The authors hold that injecting chemicals is an effective method to control diseases and pest insects. This technique is ecology friendly and in harmony with the use of natural enemy.
