摘要
为探究不同助剂对无人机喷雾雾滴沉降和飘移的影响,评价其作为喷雾助剂的可行性,破解无人机喷雾的关键技术,该研究以无添加助剂为对照,在喷雾药液中分别添加不同用量的5种助剂,开展雾滴检测和野外防治试验,分析不同助剂及其不同用量对雾滴的沉降分布、飘移及防效的影响。结果表明:与对照相比,添加U伴、加加乐等5种助剂均能显著降低雾滴的飘失,最适用量均为90 mL/hm^(2),助剂可大幅提高雾滴在靶标区域的沉积量,提升防治效果。
In order to investigate the effects of different adjuvants on the deposition and drift of UAV spray droplets,evaluate the feasibility of UAV spray adjuvants and reveal the key technologies of UAV spray,this study adds 5 kinds of adjuvants at different dosages into the spray solution and takes no adjuvants as control,to carry out the testing of droplet and pest control in field,and analyze the effects of different adjuvants and different dosage on droplet deposition distribution,drift and control effect.The results show that,compared with the control,the droplet loss is significantly reduced by adding 5 adjuvants,including U-partner and Galle,and the most suitable dosage is 90 mL/ha.Adjuvants can significantly increase the droplet deposition in the target region and enhance the control effect.
