Scope

Scope: This standard specifies the production technical requirements for the high-quality and efficient cultivation of green rice, including site selection, land preparation, seedling cultivation, transplanting, fertilization, irrigation, integrated prevention and control of diseases, pests, and weeds, and harvesting. This standard applies to the green rice high-quality and efficient cultivation in the Liaohe Delta region and similar ecological areas. Main technical content: 1. Balanced fertilization technology: Fertilizer application shall comply with the relevant provisions of NY/T 394-2013, and fertilizers permitted for green rice production shall be used. Increase the application of organic fertilizers to reduce the amount of chemical fertilizers, and balance the application of nitrogen, phosphorus, potassium, and silicon fertilizers. Base fertilization should be combined with mechanical land preparation and transplanting to achieve full-layer application. Apply fully composted high-quality agricultural fertilizers (22.5–30.0 t/hm2) before plowing or rotary tillage. Apply 150–180 kg/hm2 of nitrogen fertilizer, 75–90 kg/hm2 of phosphorus fertilizer, 90–150 kg/hm2 of potassium fertilizer, 1200–1500 kg/hm2 of silicon fertilizer (SiO2 content ≥20%) and 22.5 kg/hm2 of zinc fertilizer (ZnSO4 content ≥21%). The nitrogen fertilizer is divided into 60–70% base fertilizer, 20–30% tillering fertilizer (with a ratio of 4:6 for the first and second tillering fertilizer), and 10–15% panicle fertilizer. The base fertilizer is applied before rotary tillage, and the tillering fertilizer is applied twice at the 1st and 3rd leaf stages after transplanting. The panicle fertilizer is applied at the 4th leaf stage of rice heading. All phosphorus, silicon, and zinc fertilizers are applied as base fertilizer, and the potassium fertilizer is divided into 65% for the second tillering fertilizer and 35% for the panicle fertilizer. The nitrogen fertilizer used for base fertilization is r
