摘要
[目的]明确植保无人机在水稻田防除杂草的应用前景和在除草剂用药量、喷液量都减少的情况下对杂草的防治效果。[方法]以3%氯氟吡啶酯乳油为药剂,利用P202018款植保无人机对野慈姑进行防治试验和对水稻安全性的影响进行研究。[结果]在3%氯氟吡啶酯乳油减量50%,喷液量减少86.7%的情况下,药后15 d对野慈姑的株防效在96.7%以上,药后30 d对野慈姑的株防效在95.6%以上,鲜重防效在99.3%以上。[结论]植保无人机防除水稻田杂草高效、经济,对水稻的株高、有效穗数和产量无影响,对水稻安全。
[Objective]To test the application prospect of plant protection UAV for weed control in paddy field,and control effect of weeds under the condition of reducing spraying dosage and volume.[Method]3%florpyrauxifen EC and plant protection UAV(P202018)were used to control Sagittaria trifolia L..[Result]The control efficiency was over 96.7%for weed plant number after 15 days,and over 95.6%and 99.3%for weed plant number and fresh weight after 30 days respectively when dosage was reduced 50%,spraying volume was reduced 86.7%.[Conclusion]It was efficiency and economy for plant protection UAV to spray herbicide in paddy field,and without any adverse effect on rice plant height,effective panicle number and yield.
