摘  要:利用KT-10-Ⅱ型四旋翼植保无人机开展玉米灌浆期三点斑叶蝉的防治试验,研究无人机飞行高度、飞行速度、施药液量以及喷雾助剂等因素对农药雾滴在玉米冠层的沉积分布影响及对三点斑叶蝉防效的影响。结果表明:在无人机飞行高度为距玉米株冠顶部1m、飞行速度6m/s、施药液量15L/hm2,并加入1.5%喷雾助剂"迈飞"的条件下,喷雾雾滴在玉米冠层上部、中部和下部的沉积密度分别达到41.9、27.3和14.9个/cm2,对三点斑叶蝉药后1d防效可达91.3%,药后14d防效96.8%以上,速效性和持效性均较理想。Field trials were conducted with the KT-10-Ⅱfour-rotor unmanned aerial vehicles(UAV)to control Zygina salina Mit during grain filling stage in maize.The influence of UAV's flight altitude,velocity,spray volume and special additives on the deposit distribution of pesticide droplet on maize canopy was investigated and the control effect on Z.salina was also studied.The results showed that under the conditions of 1 mflying altitude from the corn crown top,6 m/s flying speed,15 L/hm2 spray volume and 1.5% spray adjuvants"Maifei",the spray droplet deposit's density on the upper,middle and lower part of corn canopy were 41.9,27.3 and 14.9 particle/cm2,respectively.The control efficacy was 91.3% and 96.8% at the first and the 14 th day after spraying pesticides with KT-10-Ⅱ UAV,respectively.The results indicated that this optimized method was of quick and persistent action on the control of Z.salina Mit.
