Basic Information
Scope
Scope: This standard specifies the terms and definitions, production environment, cultivation techniques, selenium-enrichment techniques, timely harvesting, and file management for the cultivation of selenium-enriched lentils. This standard applies to the cultivation of selenium-enriched lentils. 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. The seed quality should comply with the provisions of GB 4404.2. 5.2 Field management: Techniques such as cultivating strong seedlings, preparing the soil and applying fertilizer, timely transplanting, reasonable planting density, fertilizer and water management, and pest and disease control can be implemented according to local field management techniques. 5.3 Fertilizer application: Fertilizer application should comply with the provisions of NY/T 394. 5.4 Chemical pest and disease control: Chemical pest and disease control should comply with the provisions of NY/T 393. 6. Selenium-enrichment techniques: 6.1 Selenium supplementation principle: When the selenium content in the lentil fruits produced naturally does not meet the requirements of GH/T 1135, selenium can be supplemented through artificial techniques. 6.2 Selenium fertilizers should be selected from selenium fertilizers or selenium soil conditioners registered by the state. 6.3 Selenium supplementation methods: Leaf surface selenium supplementation and rhizosphere selenium supplementation. One or both methods can be selected according to actual production needs. 6.3.1 Leaf surface selenium supplementation: Prepare a selenium solution with a concentration of 70mg/kg to 120mg/kg. Supplement selenium once each at the flower bud stage, flowering stage, and early fruit stage, and once every 2 harvests. Spray
