Scope

Main technical content: This document specifies the terms and definitions, equipment, pre-sowing preparation, cultivation techniques, field management, and harvesting requirements for the mechanized production of the rapeseed variety "Qinyou 1618" of the "Yangling Agricultural Science" seed brand. This document is applicable to the mechanized production and management of the rapeseed variety "Qinyou 1618" of the "Yangling Agricultural Science" seed brand in the Huaiyang District of Hebei Province. 5.4 Fertilization should be carried out according to local agronomic requirements, soil fertility, and yield targets, with a reasonable calculation of fertilizer dosage. The dosage and proportion of nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, and boron fertilizer should comply with the relevant provisions of NY/T 790. Base fertilizer should be applied deeply, and methods such as spreading fertilizer before plowing or using integrated fertilizer-plowing machines can be adopted. In empty fields, the base fertilizer should be 30 kg of compound fertilizer (15%-20% nitrogen, 5% phosphorus, and 5% potassium) or 10 kg of urea plus 15 kg of diammonium phosphate; for early corn or silage corn stubble fields, or rice stubble fields, an additional 5-7.5 kg of urea should be added to the above fertilization amounts. 6.3.1 Seeding methods: Select high-precision rapeseed seeders to complete operations such as trenching, sowing, soil covering, and compaction in one go. If the field is too wet or mechanical sowing is not feasible, shallow rotary trenching, direct sowing, or no-till sowing methods can be used for seeding.
