Scope

Scope: This document specifies the origin, characteristics, cultivation techniques, and suitable regions of the rapeseed variety "Shaan Oil 168" from the "Yangling Agricultural Science" seed industry brand. This document is applicable to the authenticity identification, field appraisal, and large-scale production of the rapeseed variety "Shaan Oil 168" from the "Yangling Agricultural Science" seed industry brand. Main technical content: 6.1 Spring sowing techniques: 6.1.1 Sowing in spring areas can begin after soil thawing, with attention to timely sowing and late frost damage. In Xinjiang and Inner Mongolia, sowing generally takes place from mid-April to mid-May, while in Qinghai and Gansu, sowing occurs from late March to mid-April. 6.1.2 Direct sowing seeding rate: 0.3 kg/667 m2 to 0.5 kg/667 m2. In areas with shorter growth periods, such as Hulunbuir in Inner Mongolia, the minimum seedling density should be at least 60,000 plants/667 m2; in Xinjiang, Qinghai, and Gansu, the minimum seedling density should be at least 30,000 plants/667 m2. 6.1.3 Apply sufficient base fertilizer, increase phosphorus and potassium fertilizer application, and ensure adequate boron fertilization. For rapeseed fields with a yield of 200 kg/667 m2 to 250 kg/667 m2, the pure nitrogen application should be 10 kg/667 m2 to 14 kg/667 m2; the phosphorus fertilizer application can be half of the nitrogen amount; and in potassium-deficient areas, the amount should be supplemented according to soil content. Boron fertilizer can be applied as borax at 0.50 kg/667 m2 to 0.75 kg/667 m2, or spray 100 g/667 m2 of high-efficiency soluble boron fertilizer during the bud-flowering stage. Apply diammonium phosphate at 20 kg/667 m2 and urea at 4 kg/667 m2 to 5 kg/667 m2 in time. Carry out seedling thinning and transplanting in a timely manner. During the seedling stage (4-5 leaves), apply urea at 6 kg/667 m2 to 8 kg/667 m2. 6.1.4 After seedling emergence, pay attention to aphids and stem aphids. After
