摘要 以雪茄烟叶施药为例,通过测定2款无人机在相同条件下的雾滴覆盖密度、雾滴分布均匀度、雾滴粒径、雾滴谱宽度、喷雾沉积量、沉积量分布均匀度、有效喷幅宽度等技术指标,评估了2款无人机在雪茄烟叶施药中的作业质量。结果表明,2款无人机的作业质量技术指标符合作业要求,对雪茄烟植株均具有较好的穿透性,但在植株反面的沉积效果较差。不同型号的无人机具有不同的沉积效果及有效喷幅宽度。该试验结果为筛选适用于雪茄烟精准施药的无人机型号提供了参考,同时也为无人机作业性能优化、作业效率提升提供了技術依据。

Abstract Taking the medication for cigar tobacco leaves as an example, the droplet’s coverage density, droplet’s  distribution uniformity, droplet’s particle size,droplet spectrum width, spray deposition amount, distribution uniformity of deposition amount, effective spray width and other technical indices of two types of unmanned aerial vehicle(UAV) under the same conditions were determined to evaluate the operational quality of the two types of UAVs in the medication of cigar tobacco leaves. The results showed that the operational qualityand technical indices of the two types of UAVs met the operational requirements.They both had good penetrability on cigar tobacco plants, but the deposition effect on the opposite side of tobacco plants was poor. Different types of UAVs had different deposition effects and effective spray width. The test results provided references for the selection of UAV models for the precise medication of cigar cigarettes, and provided the technical basis for the optimization of the operational performance and the improvement of operational efficiency of UAVs .

植保无人机是近年来快速发展的一类空中施药器械,与地面施药器械相比,具有机动灵活、施药效率高、作业质量好、施药量和用水量少、不损伤农作物等优点。截至2019年底,我国共有农用植保无人机型号170多个,保有量5.5万余架,2019年作业面积超过0.567亿hm2,防治作物包括水稻、小麦、玉米、棉花等[1],为我国农业现代化和规模化发展发挥了重要作用。……
