中文摘要:
      采用3WQF120-12型油动单旋翼植保人机进行喷雾试验,探索植保人机在棉花上喷洒的雾滴沉积分布规律。以吡虫啉(imidacloprid)和丁硫克百威( carbosulfan)为试验药剂,在2种施药量(常规剂量和减量20%)、2种喷雾量(12、15 L/hm2)条件下喷雾,以诱惑红水溶液为药剂沉积指示剂,采用雾滴测试卡检测雾滴沉积分布情况,并利用图像分析软件DepositScan分析雾滴沉积分布状况。试验结果显示:喷液量对吡虫啉在棉花冠层的雾滴沉积分布影响较大,90 g/hm2吡虫啉施药时,采用12、15 L/hm2的喷液量进行人机喷雾,在棉花冠层的沉积量分别为99.64、128.04 μg/cm2;按照72 g/hm2剂量喷雾时,2种喷液量处理在棉花上的沉积量分别为75.09、101.32 μg/cm2。施药量影响丁硫克百威在棉花上的沉积,喷液量为12 L/hm2时,施药量为480、600g/hm2的喷雾处理在棉花上的沉积量分别为613.92、801.59 μg/cm2;喷液量为15 L/hm2时,2种施药量处理在棉花上的沉积量分别为620.17、870.64 μg/cm2。雾滴沉积分布结果显示,15 L/hm2的喷雾处理在棉花叶片背面的雾滴沉积密度较大,为0.8~238.9个/cm2;12 L/hm2的处理在叶片正面和背面的雾滴密度较小,分别为1.4~65.9、1.1~110.7个/cm2;上述2种喷雾处理在棉花叶片正面的雾滴粒径较大,分别为83~441、113~418 μm,而在棉花叶片背面的雾滴粒径较小,仅为72~242、102~252 μm。
英文摘要:
      Spray tests were conducted with a 3WQF120-12 fuel powered single rotor UVA to study the distribution regularity of droplets deposition during aerial spraying with plant protection unmanned aerial vehicle (UAV) in cotton field.Imidacloprid and carbosulfan were separately sprayed with UAV under two spray dosages including conventional dose and 20% dose reduction,and two spray volumes including 12 L/hm2 and 15 L/hm2.Allura red was used as tracer to measure the pesticide spray distribution.The parameters of droplets were tested with droplets test card and analyzed with image processing software DepositScan.The results showed that spray volume had a great influence on the droplets deposition of imidacloprid on cotton.The droplet depositions of imidacloprid on cotton were 99.64 μg/cm2 and 128.04 μg/cm2 under the spray volumes of 12 L/hm2 and 15 L/hm2 with the spray dosage of 90 g/hm2.The droplet depositions of these two volume groups on cotton were 75.09 μg/cm2 and 101.32 μg/cm2 when the spray dosage was 72 g/hm2.Spray dosage had a great influence on the droplets deposition of carbosulfan on cotton.The droplet depositions were 613.92 μg/cm2 and 801.59 μg/cm2 under the spray volume of 12 L/hm2 when the spray dosages were 480 g/hm2 and 600 g/hm2.The droplet depositions of these two dosage groups on cotton were 620.17 μg/cm2 and 870.64 μg/cm2 under the spray volume of 15 L/hm2.The results of analyzing droplets distribution showed that droplets density on the underside of cotton leaves ranging from 0.8 cm-2 to 238.9 cm-2 were higher than that of upperside when the spray volume was 15 L/hm2.The droplets density of the spray volume of 12 L/hm2 were lower than that on the upperside and underside of cotton leaves ranging from 1.4 cm-2 to 65.9 cm-2 and from 1.1 cm-2 to 110.7cm-2,respectively.The droplets size of the two spray volumes on the upperside of cotton leaves were larger and ranged from 83 μm to 441 μm and from 113 μm to 418 μm.The droplets size on the underside of cotton leaves were smaller and ranged from 72 μm to 242 μm and from 102 μm to 252 μm.It will provide references for applying and extending UAV to prevent and control pest in the cotton field.
