赣南茶区植保无人机飞防药液雾滴沉积分布与地面流失率影响因素研究
Study on the Influencing Factors of Droplet Deposition Distribution and Ground Runoff Rate of Aerial Spray Liquid by Plant Protection Drones in Southern Jiangxi Tea Region
摘要
Abstract
To promote the application of plant protection unmanned aerial vehicles(UAVs)for tea plants in the Gan-nan region and improve flight control efficacy,an orthogonal field experiment was conducted using a quad-rotor plant protection UAV with flight height,flight speed,and droplet size as operational factors.Based on indicators in-cluding droplet distribution characteristics,deposition amount,and ground loss rate,the influence patterns of flight factors on control efficacy were revealed,and optimal operational parameters were obtaineed.The results show that UAV flight height,flight speed,and droplet size significantly affected the deposition amount on both the surface and interior of the tea canopy(P<0.05),with flight height being the primary influencing factor.The optimal flight parameters for tea plants in the Gannan region were a flight height of 2 m,a flight speed of 2.5 m/s,and a droplet size of 200 μm.Regarding ground loss rate,all three flight factors exhibited highly significant effects(P<0.001).Under the condition of controlling ground loss rate,flight height and flight speed should be appropriately increased while reducing droplet size to ensure a balanced trade-off between droplet deposition effectiveness and pesticide uti-lization efficiency.This study provided theoretical support for improving the quality and efficiency of UAV spray-ing operations in Gannan tea gardens.关键词
