Scope

Main Technical Content: 4. Cultivation Techniques For cultivation techniques not specified in this clause, conventional farming and agronomic techniques shall be used. 4.1 Land Preparation and Moisture Control The land should be well-compacted with no visible or hidden clods. Straw should be returned to the field twice, with straw length below 5 cm. Deep tillage should be controlled at about 25 cm, and deep loosening at about 30 cm. Soil moisture should be maintained at 70%–80% of the maximum water-holding capacity in the field. For arid soils, moisture should be added one week before plowing, and sowing should not be rushed. 4.2 Application of Base Fertilizer For a medium-yielding field with a target yield of 650 kg/mu, apply 4,000 kg of organic fertilizer, 10 kg of pure nitrogen (N), 8–10 kg of phosphorus (P2O5), and 6–8 kg of potassium (K2O). For a high-yielding field with a target yield of 700 kg/mu, increase fertilizer dosage by about 20%; for a low- to medium-yielding field with a target yield of 600 kg/mu, decrease fertilizer dosage by about 20%. Micronutrient deficiency areas should be supplemented with zinc and boron fertilizers. The fertilizers used should comply with NY/T 394. 4.3 Seed Selection and Treatment Seed quality should meet the requirements of GB 4404.1-2008, with purity ≥99%, cleanliness ≥99%, germination rate ≥85%, and moisture content ≤13.0%. Use low-toxicity seed coatings and follow GB 15671-2009 standards. 4.4 Sowing The sowing period is generally from October 5 to 10. The basic seedling number should be 180,000–220,000/mu, with 180,000 being ideal. For early-sown and high-fertilized fields, reduce sowing density slightly; for late-sown and low-fertilized fields, increase sowing density slightly. Add 0.5 kg/mu for every 3 days of late sowing. Use strip sowing and promote precision sowing with mechanical equipment. Row spacing should be 20–25 cm, and sowing depth 3–5 cm. Compact the soil after sowing to promote root devel
