无人机作业参数对苹果树雾滴沉积分布的影响
Effects of Operating Parameters on the Droplets Distribution By Unmanned Aerial Vehicle in Apple Trees
摘要
Abstract
In order to study the distribution of droplets of plant protection drones in apple fruit trees,the JF01-20 elec-tric octa-rotor four-axis plant protection drone was selected as the test platform to explore the effects of flight speed and spray adjuvant on the distribution of droplets in apple fruit trees.The experiment set up six groups of experimental treat-ments,using water-sensitive paper(WSP)as a test tool for distributing droplets.The WSPs were respectively arranged on the upper,middle,and lower canopy layers of apple trees.The distribution data of droplets in the canopy layer of ap-ple trees were counted.The research results show that the distribution of droplets on the same canopy level of fruit trees is quite different,and the variation coefficient of droplet distribution varies from 49.1%to 227.6%;the numerical re-sults of the distribution of droplets gradually decrease from top to bottom in the canopy of fruit trees.The numerical re-sults of droplet distribution decrease with the increase in flight speed,and the changing trend of each droplet test index is the same.After adding the adjuvant,the results of the droplet distribution between each experimental treatment and cano-py were significantly improved.The research provides data support for the spraying application of plant protection drones on apple orchards.关键词
