无人植保机雾化颗粒大小对喷洒效果的影响

Effect of Atomized Particle Size of Unmanned Plant Protection Machine on Spraying Effect

近年来,植保无人机技术快速发展,逐渐成为植保行业的重要力量,植保作业模式也从最开始的粗放式向精细化和精准化迈进。文章从无人机植保效果、效益出发,分析了无人机在植保作业过程中,药液雾化形成的雾滴直径大小对雾滴在标的作物表面沉降以及黏附效果产生的影响。要结合标的作物、农药、病虫害特性,通过对无人机植保过程中对喷洒流量和雾滴粒径的双精准控制,才能达到植保效果和效益的最优化。

In recent years,the rapid development of plant protection UAV technology has gradually become an important force in the plant protection industry,and the plant protection operation mode has also moved from the initial extensive mode to the refinement and precision.Based on the plant protection effect and benefit of UAV,this paper analyzes the influence of the droplet diameter formed by the atomization of the chemical solution on the surface settlement and adhesion effect of the droplet on the target crop dur‐ing the plant protection operation of UAV.In combination with the characteristics of target crops,pesticides,diseases and pests,the optimization of plant protection effect and benefit can be achieved through the double accurate control of spray flow and droplet size in the process of UAV plant protection.
