Scope

Scope: This document specifies the terms and definitions, operational requirements, workflow, pesticide selection and dosage, post-sealing water management, and post-operational maintenance for the closed weed control operation of drones in direct-sown rice production in the Yonghe Irrigation District of Ningxia. This standard applies to direct-sown rice production in the Yonghe Irrigation District of Ningxia. Main technical content: 3. Terms and definitions: The terms and definitions defined in DB64/T 1146-2015 and the following terms and definitions apply to this document. Direct-sown rice: A rice production method in which rice seeds are directly sown into the field without nursery and transplantation. Soil closed weed control: A weed prevention measure that inhibits the germination of weeds in rice fields by applying chemical pesticides before rice seedling emergence. 4. Operational requirements: - Operators of drone sprayers must comply with the requirements of DB64/T 1851-2022. - Select a flat and open area as the takeoff and landing site for drone operations, and set up safety warning signs around the site. - Add a special additive to the pesticide solution, with a spray volume of 1000 ml/667–1200 ml/667. - Maintain a constant flight speed of 3–5 m/s and a flight height of 3–4 m during operations. 5. Workflow: - Conduct a field survey of previous crops, planting methods, and weed types before operations, taking into account weather conditions and field water levels. - Determine the herbicide type, application rate, and flight parameters based on these factors. - Record the operation data according to Appendix A and Appendix B, and archive the records for future reference. 6. Pesticide selection and dosage: - For dry direct-sown rice fields, apply 48% Zhongdingling emulsion at 100–120 ml/667 m2 within 3–7 days after irrigation. - For shallow-covered direct-sown rice fields, apply 30% Progris at 100–120 ml/667 m2 (with a safener) a
