摘 要相比于传统的喷雾法等外部树木施药技术，树干注药法是一种全新的注药方式，具有高效、药物吸收好、操作方便并且消除了杀害有益虫类等诸多优点。国内对树干注药器的研究起步较晚，落后于国外技术，目前尚处于研究与实践阶段。本文在深入分析树干注药器的工作原理的基础上，尝试在理论上研发了一种新型的便携式园林树木注射器，主要研究工作如下：

(1) 对国内外注药装置的发展现状进行研究，分析了树干注药的机理，运用工程设计学方法深入分析了树干注药器的结构特点，制定了树干注药器系统结构设计方案。

(2) 总结并研究了前人设计研发的吸剂树干注射机与电动树干注射机，扬长补短，找到各自的优缺点并改进。50736

(3) 尝试自主设计一种高效的便携式园林树木注射器，并对其零件部分进行分析得到大概的数据，在前人的基础上适当的改进创新。

Abstract Compared with the traditional external application technology, trunk injection method is drug injection  in a new way, with a painless, good medicine absorption, convenient operation, eliminating the cross infection etc.. The domestic study on tree injector started late, lagging behind the foreign technology, is still in the development stage. Based on the working principle of in-depth analysis on the trunk injection device, try in theory research and development of a new portable garden trees syringe, the main research work is as follows:

   (1) Study on current situation and development of the injection device, mechanism of trunk injection was analyzed, using the in-depth analysis of the structure characteristics of trunk injection method for engineering design, formulated the trunk injection system structure design.

   (2) Summary and study of previous designed adsorbent trunk injection machine and electric trunk injection machine，we will find their strengths and weaknesses.Then we make it better based on these.

   (3) Try to own an efficient design of portable garden trees syringe, and the parts were analyzed by general data, appropriate improvement and innovation on the basis of the previous.

 Keywords: tree injector, innovative design, portable，efficient
