Scope

Scope: This standard specifies the terms and definitions, production environment, cultivation techniques, selenium-enrichment technologies, timely harvesting, and file management for the selenium-enriched cultivation of melons. This standard applies to the selenium-enriched cultivation of melons. Main technical content: 4. Production environment: The base should be selected in areas with selenium-rich soil, and the production environment should comply with the provisions of NY/T 391. 5. Cultivation techniques: 5.1 Variety selection: Select varieties with high quality, high yield, and strong resistance, and the seed quality should comply with the provisions of GB 16715.1. 5.2 Field management: Techniques such as seedling cultivation, land preparation and fertilization, timely transplanting, reasonable planting density, fertilizer and water management, and pest and weed control can be implemented in accordance with local field management techniques. 5.3 Fertilizer application: Fertilizer application should comply with the provisions of NY/T 394. 5.4 Chemical control of pests and weeds: Chemical control should comply with the provisions of NY/T 393. 6. Selenium-enrichment technologies: 6.1 Selenium supplementation principle: When the selenium content in melon fruits produced naturally does not meet the requirements of GH/T 1135, selenium can be supplemented through artificial techniques. 6.2 Selenium supplementation fertilizers should be selected from nationally registered selenium fertilizers or selenium soil conditioners. 6.3 Selenium supplementation methods: Leaf surface supplementation and rhizosphere supplementation. One or both methods can be selected according to actual production needs. 6.3.1 Leaf surface supplementation: Prepare a selenium solution with a concentration of 70mg/kg to 120mg/kg. Supplement selenium once each at the budding stage, flowering stage, and early fruit stage, and once every two harvests. Spray 450kg to 750kg of
