中文摘要:
      对使用大载荷油动植保无人机对棕榈树进行喷施作业的效果进行了评价, 探讨了植保无人机喷洒参数对棕榈树上雾滴沉积的影响。以大载荷油动植保无人机为研究对象, 进行了正交试验, 考察了3个因素:飞行高度、飞行速度和喷头流量。经过试验比较, 当喷头流量为3.4 L/min、作业高度为3 m、作业速度为3 m/s时, 雾滴沉积密度和均匀性最佳。其中, 喷头流量对雾滴沉积密度的影响最大, 其次是作业高度和作业速度; 在穿透性方面, 喷头流量为3.4 L/min、作业高度为4 m、作业速度为4 m/s和喷头流量为4.2 L/min、作业高度为4 m、作业速度为3 m/s, 其雾滴的穿透性较强, 分别为15.83%和30.01%。影响雾滴沉积穿透性的因素依次为喷头流量、作业高度和作业速度。本试验对大载荷油动植保无人机在棕榈树合理喷施和提高喷施效果方面具有参考价值。
英文摘要:
      This study aimed to investigate the effectiveness of spraying operations on palm trees using a large-load oil-operated plant protection unmanned aircraft vehicle (UAV), with a particular focus on exploring the effect of plant protection UAV spraying parameters on droplet deposition on palm trees. Using a large-load oil-operated plant protection UAV as the research object, orthogonal tests were conducted to examine three factors, including flight height, flight speed and nozzle flow rate. After experimental comparison, the best droplet deposition density and uniformity was achieved when the nozzle flow rate was 3.4 L/min, the working height was 3 m and the working speed was 3 m/s. The nozzle flow rate had the highest effect on droplet deposition density, followed by working height and working speed. In terms of penetration, the nozzle flow rate of 3.4 L/min, working height of 4 m and working speed of 4 m/s and the nozzle flow rate of 4.2 L/min, working height of 4 m and working speed of 3 m/s had a higher droplet penetration rate of 15.83% and 30.01%, respectively. The factors influencing the penetration of droplet deposition were, in order, the nozzle flow rate, working height, working speed. The above results are of reference value for the rational spraying and improvement of the spraying effect of large-load oil-operated UAV on palm trees.
