我国果园施药技术与配套地面装备研究进展OA

Orchard pesticide application equipment is an important branch of plant protection machinery.Its performance and operation quality directly affect the efficacy of orchard pest and diseases control,and determine the quality and yield of fruit.Firstly,this paper comprehensively analyzed the research progress of pesticide application technology in China,including airflow-assisted spray technology,electrostatic spray technology,cyclic spray technology and precise variable pesticide application technology.The working principle and existing problems were elaborated,respectively.Then,situation of the orchard sprayers was described taking the air-assisted sprayer as an example which was the most widely used for pesticide application in orchard.Specifically,the development of pesticide application equipment and key components of sprayers in China orchards were analyzed.This paper points out the existing problems in areas such as pesticide application techniques in orchards,the degree of integration between machinery and agriculture,the promotion and research efforts,and adaptability in our country.The orchard should be mechanically reformed,the research and development ideas of intelligent equipment should be developed,so as to provide reference for the development of intelligent,refined,efficient and green pesticide application equipment in orchards in China.
