摘　　要：为了研究植保无人机在小麦田草害防治中的施药效果以及安全性,以炔草酯防除小麦田硬草[Sclerochloadura(L.)Beauv.]为例,通过极飞P20植保无人机喷雾和易田3WYTZ1000-21自走式喷杆植保机喷雾2种不同施药方式开展药效试验。结果表明,极飞P20植保无人机喷施8%炔草酯EW1200mL/hm^2对小麦安全,且防治效果与易田自走式喷杆植保机无显著差异,药后30d校正株防效和鲜质量株防效分别达89.96%和98.89%。The purpose of this study was to evaluate the outcome of applying plant protection UAV to control stiffgrass [Sclerochloa dura (L.) Beauv.] with clodinafop-propargyl with respect to its effectiveness and safety for wheat in a wheat field.Clodinafop-propargyl was applied to the field using two different methods: spray with a plant protection drone;spray with a large mechanical sprayer.The results showed that using XAIRCRAFT plant protection UAV to spray 8% clodinafop-propargyl EW 1 200 mL/hm^2 was safe for wheat,whose control efficacy was not significantly different from that of Yitian automatic-moving sprayer.Applied with XAIRCRAFT plant protection UAV,clodinafop-propargyl attained the corrected control efficacy of 89.96% and the efficacy based on the fresh weight of grasses of 98.89% at 30 days after treatment.
