不同植保无人机喷头雾滴特征及对玉米田杂草的防控效果研究
摘要
Abstract
In order to clarify the droplet characteristics of different types of plant protection UAV nozzles sprayed with 40% nitrate·nicosol·herbicide OD and their prevention and control effect on post-seedling weeds in corn fields,this study used droplet size,droplet density,coverage and control efficiency as indicators,selected 6 plant protection UAVnozzle types,and designed 7 treatments with backpack sprayer spraying clear water as control.The research results showed that the droplets sprayed with 40% nitramine·nicosol·herbicide OD by TEEJET SJ3,TEEJET SJ7A and LRCHLER FS nozzles had large particle size,low density,and poor uniformity,but had small drift distance,which had good control effect on post-seedling weeds in corn fields.TEEJET AI 110 and LRCHLER IDK 90 nozzles spray 40% nitramine·nicosol·herbicide OD with small droplet size and uniform spray,but the anti-drift effect is poor.The drift area can be controlled to 10～12m,and the prevention and control effect on post-seedling weeds in corn fields is average.The LRCHLER ST 110 nozzle sprayed with 40% nitramine·nicosol·herbicide OD has the smallest droplet size and the smallest density,but the drift distance is the longest,and has poor control effect on post-seedling weeds in corn fields.关键词
