Main Technical Content: 5. Origin Environment 5.1 Climate Conditions The Zhongjiang Salvia miltiorrhiza is suitable for the subtropical humid monsoon climate zone in the Sichuan Basin. The average annual temperature is around 16.7°C, with an average annual sunshine duration of approximately 1,163 hours and an average annual rainfall of around 841.8 mm. The frost-free period lasts approximately 282 days. 5.2 Environmental Conditions The environment should comply with the requirements of DB51/T1068-2010. Purple soils in hilly and low mountainous areas are preferred, with a soil thickness of ≥50 cm, convenient irrigation, loose and moist soil with moderate fertility, and a pH of 7.0–8.0. Avoid selecting land with repeated Salvia miltiorrhiza planting, vegetable gardens, or bean-planted fields. 7. Field Cultivation Management 7.3 Opening and Ridging Apply base fertilizer (4.2–6.3 kg of pure N, 3–4.5 kg of P2O5, and 2.8–4.2 kg of K2O per 667 m2) along the centerline of the ridge and cover the soil. The optimal ridge spacing is 80 cm, ridge width 50 cm, ridge height 30 cm, and ridge gutter width 30 cm. Require straight ridges and level surfaces. After sufficient irrigation with composted manure, cover with a film. 7.7.3 Fertilizer Dosage Apply 1,000–1,500 kg of composted organic fertilizer and 6–9 kg of pure N, 3–4.5 kg of P2O5, and 4–6 kg of K2O per 667 m2. Use organic fertilizer as base fertilizer, and apply 70% of the fertilizer as base fertilizer and 30% as top dressing, with top dressing applied based on soil conditions, growth stage, and plant requirements. 8. Disease and Pest Control 8.3 Pesticide Use Follow the provisions of DB51/337-2003. The main disease and pest symptoms of Zhongjiang Salvia miltiorrhiza are described in the appendix. 10.
