无人机喷雾施药对松丽毒蛾幼虫的药效评价

Evaluation on the Efficacy of Spraying Insecticide by UAV on the Larva of Dasychira axutha

摘要: 于2021年,在福建省沙县的马尾松林建立试验区,选用6种生物农药,运用人工喷雾与无人机喷雾2种施药方式,开展防治松丽毒蛾幼虫对比试验。结果表明:无人机喷雾施药的防治效果显著好于人工喷雾施药,无人机喷雾施药的作业工效为1.33 hm²·h^-1,是人工喷雾施药(0.15 hm²·h^-1)的8.87倍,人工喷雾作业的人工费用为无人机喷雾作业的5倍。无人机喷雾施药表现出强大的技术优越性,具有高工效、低费用、易操作等显著优点,是一种节时、省力、降费的施药方式。

Abstract: In 2021, a trial area was established in the Pinus massoniana forest in Sha County, Fujian Province, 6 kinds of biological pesticides were applied by artificial spraying and UAV spraying, and the control effect, work efficiency and cost were compared.The results showed that the control effect of spraying by UAV was significantly better than that by manual spraying.The work efficiency of spraying by UAV was 1.33 hm²·h^-1, which was 8.87 times higher than that by manual spraying 0.15 hm²·h^-1, the labor cost of manual spraying operation is 5 times of that of UAV spraying operation.UAV spray application shows strong technical advantages, with high efficiency, low cost, easy to operate and other significant advantages, for a time-saving, labor-saving, cost-reduction method of application.
