This document is applicable to herbicide spraying with drones in spring wheat fields in the Yinchuan irrigation area of Ningxia Hui Autonomous Region. Main technical content: 3. Terms and definitions: There are no terms or definitions requiring definition in this document. 4. Basic requirements: Drones shall comply with the provisions of NY/T 3213. Operators include flight controllers, auxiliary operators, and safety managers. Flight controllers and safety managers shall be trained to understand the occurrence patterns of weeds in spring wheat fields and master safe pesticide application skills. Flight controllers must obtain training certificates from relevant institutions. 5. Herbicide selection: Herbicide selection shall comply with the provisions of NY/T 1276. Herbicide application shall comply with the provisions of GB/T 8321.1~8321.10. For controlling grass weeds such as barnyardgrass and dogtail grass, select herbicides such as sethoxydim or clethodim for stem and leaf spraying; for controlling broadleaf weeds such as purslane and impatiens, select herbicides such as 2,4-D butylate emulsion or sulfentrazone for stem and leaf spraying. 6. Field operations: Weeding before the spring wheat heading stage is more effective after irrigation. The pesticide solution shall be diluted twice and appropriate flight protection agents shall be added. The pesticide dosage is 1500 ml/667 m2~2500 ml/667 m2. The flight speed is 3 m/s~5 m/s, with a constant speed flight, and the flight height is maintained at 2 m~3 m. 7. Meteorological conditions: Before operations, the temperature, humidity, wind direction, and wind speed in the operation area shall be checked. Op
