无人机喷雾器具有工作效率高的优点,操作简单,安全系数高,无人机喷雾器广泛应用于农业领域,无人机喷雾技术在农业中的应用为农民提供了便利和增加了利润,也成为农业领域的研究热点。近年来,尽管已经对无人机喷雾器喷洒冠状植物的可行性和应用效果进行了研究,在园林植物领域还没有实验或研究。本实验进行了无人机喷雾器喷洒园林植物的液滴沉积实验,探索无人机喷雾器在园林植物领域的液滴沉积效果,并进行了喷雾量和喷嘴类型对液滴沉积影响的实验。实验结果表明,在飞行高度为1.5m时,中小型园林植物的冠层性能较好,喷雾量为180L/hm2,飞行速度为2m/s。降低飞行高度,增加喷雾量,降低飞行速度可以改善雨滴在雨篷中的分布。本试验为无人机喷雾机在园林植物病虫害防治中的应用奠定了基础,以及增长调节剂的应用,为园林植物应用技术领域的进一步创新研究提供了依据。
The Unmanned Aerial Vehicle (UAV) sprayer has the advantages of high work efficiency, simple operation, and high safety factor, and has broad application prospects UAV sprayer are widely used in the agricultural field, and the application of UAV sprayer spraying technology in agriculture has provided convenience and increased profits for farmers, and has also become a research hotspot in the field of agriculture. In recent years, although research has been conducted on the feasibility and application effects of UAV sprayer spraying crown shaped plants, there have been no experiments or studies in the field of garden plants. This experiment conducted a droplet deposition experiment of UAV sprayer spraying garden plants, exploring the droplet deposition effect of UAV sprayer in the field of garden plants, and conducting experiments on the influence of spray volume and nozzle type on droplet deposition. The experimental results showed that the canopy performance of small and medium-sized garden plants was better at a flight altitude of 1.5m, a spray volume of 180L/hm2, and a flight speed of 2m/s. Reducing flight altitude, increasing spray volume, and reducing flight speed can improve the distribution of droplets in the canopy. This experiment lays the foundation for the application of UAV sprayer for the prevention and control of pests and diseases in garden plants, as well as for the application of growth regulators, and provides a basis for further innovative research in the field of garden plant application technology.
