中文摘要:为选择用于植保无人机作业的喷雾助剂，利用全自动张力仪和接触角测量仪测定添加4种不同喷雾助剂后0.5%氯虫苯甲酰胺药液的表面张力及在玉米叶片上的接触角，应用大疆T20型植保无人机进行田间喷雾，分析添加4种喷雾助剂对玉米冠层不同位置雾滴密度、雾滴覆盖率和雾滴沉积量的影响。结果显示，添加迈飞和Agrospred 910喷雾助剂后，药液的表面张力分别较未添加助剂时显著降低19.6%和30.1%；不同喷雾助剂对药液在玉米叶片上接触角的影响各不相同，添加Agrospred 910助剂后液滴接触叶片60 s后接触角降至11.92°；添加4种喷雾助剂能够有效提高玉米冠层的雾滴密度、雾滴覆盖率和雾滴沉积量，其中添加Agrospred 910助剂后雾滴密度、雾滴覆盖率及雾滴沉积量分别较对照增加了36.93%、35.92%和61.90%。表明在玉米田间使用植保无人机喷雾施药时，可以优选使用Agrospred 910喷雾助剂。

Abstract:In order to select spray adjuvants for plant protection using unmanned aerial vehicle (UAV), the automatic surface tension meter and contact angle measurement were used to analyze the surface tension and the contact angle of 0.5% chlorantraniliprole solutions mixed with four different spray adjuvants on maize leaves, respectively. Meanwhile, DJI T20 UAV for plant protection was used to conduct filed spray to explore the influences of adding four spray adjuvants on the droplet density，droplet coverage and droplet deposition at different positions in the maize canopy. The results showed that the addition of Maifei and Agrospred 910 spray adjuvant could significantly reduce the surface tension of the solution by 19.6% and 30.1%, respectively. The spray liquid mixed with four adjuvants had different effects on the contact angle on the maize leaves. The contact angle of Agrospred 910 spray adjuvant decreased to 11.92° after the drops fall on the leaves for 60 s. The addition of four spray adjuvants could effectively improve the droplet density and droplet deposition volume in the maize canopy. The droplet density, droplet coverage and droplet deposition increased by 36.93%, 35.92% and 61.90% respectively after the addition of Agrospred 910 spray adjuvant compared with control. Therefore, when UAV for plant protection is used to spray in the cornfields, it can be preferable to apply Agrospred 910 spray adjuvant.
