摘　　要：为明确低温条件下,采用无人机喷施2%吡草醚微乳剂对棉花脱叶效果、吐絮率,以及对棉花产量和品质性状等的影响,开展了田间药效试验。结果表明:2%吡草醚微乳剂不同处理均具有良好的脱叶效果和促进吐絮效果。施药后15 d,脱叶率在83.8%以上,吐絮率在80%以上,与对照药剂540 g/L噻苯·敌草隆悬浮剂相比,差异显著。2%吡草醚微乳剂对产量及棉花衣分、纤维长度等品质影响较小,可在低温条件下推广应用。In order to determine the defoliation effects,yield and quality characteristics of pyraflufen-ethyl 2%ME sprayed by UAV on cotton at low temperature,field experiments were conducted.The results showed that the different treatments of pyraflufen-ethyl 2%ME had good defoliation effects and promoting flocculation effects on cotton.At the 15th day after spraying,the defoliation rate was over 83.8%,and the flocculation rate was over 80%,which had significantly different with thidiazuron·diuron 540 g/L SC.Pyraflufen-ethyl 2%ME had little effects on the yield,cotton fraction,fiber length and other qualities of cotton,and could be popularized under low temperature conditions.
