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。
Tree injection application / fertilization technology, after more than 70 years of continuous research at home and abroad are making breakthrough progress: application equipment has been completed by no pressure or low pressure, low concentration, high-capacity, low ergonomic models to high pressure, high concentration, Low capacity, high efficiency model conversion; injection to expand to insecticides, fungicides, fertilizer, plant growth regulator in all aspects, and made than the spray, soil and other conventional techniques good effect; and the environment In the aspect of relations, it is proved that this is an effective and effective way for chemical prevention and control and use of natural enemies and ecological protection in harmony with each other. The downside is the low degree of mechanical automation, labor intensity is too large, the application of fungicide test to be further.
