Scope

Main Technical Content: 5. Origin Environment 5.1 Climate Conditions: Zhongjiang Salvia is suitable for the subtropical humid monsoon climate zone of 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 soil in hilly and low-mountainous areas is preferred, with a soil thickness ≥ 50 cm, convenient irrigation, loose and moist soil, moderate fertility, and a pH of 7.0–8.0. Avoid selecting land with repeated planting of Salvia, vegetable gardens, or bean stubble fields. 7. Field Cultivation Management 7.3 Furrow and Ridge Preparation: 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 with soil. The optimal ridge spacing is 80 cm, ridge width 50 cm, ridge height 30 cm, and ridge inter-row width 30 cm. Ensure the ridge is straight and level. After sufficient irrigation with composted manure, cover with a film. 7.7.3 Fertilizer Application: Apply 1,000–1,500 kg of composted organic fertilizer, 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, adjusting the application based on soil conditions, season, and plant growth. 8. Disease and Pest Control 8.3 Pesticide Use: Follow the requirements of DB51/337-2003. The main disease and pest symptoms of Zhongjiang Salvia are described in the Appendix. 10. Product Requirements 10.1 Sensory Requirements 10.1.1 The dried root should be robust, cylindrical in shape. 10.1.2 The surface should be reddish-brown or purple-red. 10.1.3 The texture should be firm, with a smooth broken surface and a sligh
