摘要
该文分析了我国森林病虫害发生的特点 ,介绍了农药使用及植保机械发展现状 ,分析了精确对靶施药系统和树形识别系统的主要内容 ,重点对树形识别系统及其与精确对靶施药系统之间的关系进行了理论分析 ,提出了将树形识别系统应用于林业精确施药中 ,试验表明树形识别系统能根据不同的树形输出不同的农药喷洒控制量 ,从而为农药的精确使用和新型植保机械的设计奠定基础。
The paper analyzed the characteristics of forest insect pests, reviewed the pesticide applications and plant protection equipment. The main ideas of precision toward-target pesticide application and tree crown recognition were analyzed briefly. Theoretical relationship analyses between tree crowns and precision pesticide applications were conducted. It was presented that tree crown recognition could be applied in the forest precision pesticide application. The experimental results showed that tree crown recognition system could output different spray volumes based on different tree crowns, which laid a foundation for precision pesticide application and design of a new type of plant protection machine.
