Abstract: 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.
