Scope
Scope: This document specifies the terms and definitions, production environment, target yield, pre-crop straw treatment, selection of supporting machinery, sowing, fertilizer application, pest and disease control, timely harvesting, and management requirements for the production of wheat in the clean zone of Nantong City and similar ecological regions using the "one base and one top-up" fertilization method. This document is applicable to the production of wheat in the clean zone of Nantong City and similar ecological regions, where wheat is sown in wide-row or narrow-row planting systems. Main technical content: - Pre-crop straw treatment: After harvesting of pre-crop crops (rice, corn, soybean), the straw is either removed from the field or shredded and evenly spread, with a straw length of 10–15 cm. - Selection of supporting machinery: The 2BFGK-12(6)260 Full Straw Stubble Clean Zone Rotary Tillage Intelligent Fertilization Sowing Machine can simultaneously complete six operations: straw relocation, strip tillage, deep application of base fertilizer, trenching, wide-row or narrow-row sowing, and compacting. - Selection of 3ZF-4(200) Inter-row Fertilization Machine: Based on the operation of the 2BFGK-12(6)260 Full Straw Stubble Clean Zone Rotary Tillage Intelligent Fertilization Sowing Machine, this machine can apply top-up fertilizer in wide rows. - Sowing: Local agricultural authorities recommend wheat varieties suitable for planting in this region, such as Yangmai No. 29 and Zhenmai No. 12. Seed quality shall comply with GB 4401.1-2008. Sowing should be conducted from late October to early November, with an appropriate basic seeding density of 120,000–140,000 plants/mu for strong-stem or medium-stem wheat, and 140,000–160,000 plants/mu for weak-stem wheat. Each day of delayed sowing increases the basic seeding density by 50,000 plants. The 2BFGK-12(6)260 Full Straw Stubble Clean Zone Rotary Tillage Intelligent Fertilization Sowing Machine is used fo
