按照植保无人机全程解决水稻病虫草害方案进行施药，能有效提升秧苗素质和分蘖数，其中株高比常规用药和空白对照高13.0%和0.4%，根长长6.4%和22.2%，白根数多41.6%和18.0%，地上部鲜质量增加14.3%和20.0%，茎基宽增加2.3%，平均分蘖数多12.2%和29.2%；对稗草、千金子为主的禾本科杂草和丁香蓼、耳叶水苋等为主的阔叶杂草防效在98%以上；对稻蓟马的防效比常规用药处理约高25个百分点，对二代二化螟和四（2）代白背飞虱防效在90%以上，对五（3）代稻纵卷叶螟的防效和保叶效果在98%以上，对褐飞虱防效在84%以上，对水稻恶苗病防效达100%，对稻曲病防效在70%以上；实测产量799.09 kg/667 m2，分别比常规用药处理和空白对照增产3.67%和 27.44%。最终实现总效益比常规用药处理增收2.67%，农药减量42.80%。

The whole process solution plan of rice diseases, insect pests and weeds by plant protection UAV （T1） could effectively improve the seedling quality and tiller number. Compared with conventional medicine treatment （T2） and CK, the plant height increased by 13.0% and 0.4% the root length increased by 6.4% and 22.2%, the white root number increased by 41.6% and 18.0%, the fresh weight of upper part increased by 14.3% and 20.0%, the base stem width increased by 2.3% and 2.3%, and the average tiller number increased by 12.2% and 29.2%. The control effect of grassy weed, such as barnyard grass and chinese sprangletop, and broad-leaved weeds, such as Ludwigiaprostrata and Ammannia arenaria, was over 98%. The control effect on rice thrips was 25 percentage points higher than T2 treatment; the control effect on second generation of Chilo suppressalis and fourth generation of white backed planthopper was more than 90%; the control effect on fifth（third） generation of rice leaf roller was more than 98%; the control effect on brown planthopper was more than 84%; the control effect on rice bakanae disease was 100%; the control effect on rice false smut was more than 70%. The yield was 799.09 kg/667m2, the total benefit increased by 2.67% and pesticide dosage decreased by 42.8% compared with T2 treatment.
