摘要
为探究植保无人机施药参数对稻纵卷叶螟防治效果的影响,本研究采用大疆T40植保无人机开展田间试验,设置不同施药液量(A1,30.0 L/hm^(2);A2,45.0 L/hm^(2);A3,67.5 L/hm^(2))与施药高度(B1,3 m;B2,4 m)双因素组合处理,系统评估药后7和15 d的保叶效果及虫量防效差异。结果表明,A3-B1处理在药后7和15 d的保叶效果(93.77%、92.58%)与虫口防效(94.76%、94.10%)在各处理中表现较优。方差分析结果显示,施药液量对稻纵卷叶螟的防治效果存在明显效应(P<0.01),而施药高度及其与施药液量的交互作用对防治效果的影响无统计学意义(P>0.05)。综合防效与作业效率,推荐采用施药液量45.0 L/hm^(2)×施药高度3 m(作业效率最优)和施药液量67.5 L/hm^(2)×施药高度3 m(防效最优)两种参数组合。研究结果为植保无人机精准防控稻纵卷叶螟提供参考。
To investigate the influence of pesticide application parameters of plant protection drones on the control efficacy against Cnaphalocrocis medinalis,field experiments were conducted using the DJI T40 protection drone.Different spraying volumes(A1,30.0 L/hm^(2);A2,45.0 L/hm^(2);A3,67.5 L/hm^(2))and spraying heights(B1,3 m;B2,4 m)were set as dual-factor combination treatments.The leaf protection efficacy and pest population control efficacy were systematically evaluated at 7 and 15 days after application.The results showed that the A3-B1 treatment exhibited the best performance among all treatments,with leaf protection efficacies of 93.77%and 92.58%,and pest population control efficacies of 94.76%and 94.10%at 7 and 15 days after application,respectively.The analysis of variance indicated that the spraying volume had a significant effect on the control efficacy against Cnaphalocrocis medinalis(P<0.01),while the spraying height and its interaction with the spraying volume showed no statistically significant impact(P>0.05).Considering both control efficacy and operational efficiacy,two parameter combinations were recommended:a spraying volume of 45.0 L/hm^(2)×spraying height of 3 m(optimal operational efficiency)and a spraying volume of 67.5 L/hm^(2)×spraying height of 3 m(optimal control efficacy).The research results provide a reference for precise prevention and control of Cnaphalocrocis medinalis by crop protection drones.
