Scope

Main technical content: This standard specifies the variety selection and breeding, planting techniques, finished product quality, labeling, packaging, transportation, storage, and quality traceability requirements for Yellow River Delta rice. It applies to the entire process of variety selection and planting of Yellow River Delta rice. Variety selection covers breeding objectives, systematic breeding, and hybrid breeding methods, and specifies seed quality, approval, and management standards. Planting techniques include site environment (limited to specific areas of the Yellow River estuary, with clear requirements for soil and water), seed treatment, sowing management, field water and fertilizer control, green pest and disease prevention, and harvesting and processing. The finished product quality sets sensory and physicochemical indicators such as broken rice rate and chalkiness, and specifies hygiene requirements and net content standards. Labeling, packaging, transportation, and storage must comply with multiple national standards. It requires the establishment of a full-process quality traceability system, with records kept for at least 3 years.
