无人机喷施封闭除草剂对大豆玉米间作田杂草的防除效果
Effects of closed herbicide spraying by unmanned aerial vehicle on weed control in soybean and maize intercropping fields
摘要
Abstract
To effectively control weeds in soybean-maize strip intercropping field,closed herbicide application of 960 g/L S-metolachlor emulsifiable concentrate(EC)was conducted using a plant protection unmanned aerial vehicle(UAV).The experiment included five treatments:three UAV application rates(1 800,2 250,and 2 700 g/hm2),one knapsack sprayer application treatment at 2 250 g/hm2,and a water spray as the control.The results showed that at the formulation dosage of 2 700 g/hm2,the application of 960 g/L S-metolachlor EC via UAV achieved the optimal weed control efficacy,with plant density reduction and fresh weight reduction rates of 85.32%and 88.45%,respectively.This treatment effectively controlled both monocotyledonous and dicotyledonous weeds in the soybean-maize strip intercropping field.Compared to the control group,the herbicide treatment significantly increased crop yields:soybean yield increased by 10.09%-17.18%,and maize yield increased by 13.90%-18.12%.In conclusion,the UAV-based application of 960 g/L S-metolachlor EC can be recommended for widespread adoption in soybean-maize strip intercropping fields.关键词
