Min County Dong Quai Chinese Medicinal Herb Seedling Base

Located in Min County, Dingxi, Gansu, reputed as the Hometown of Chinese Dong Quai, this standardized Chinese Medicinal Herb Seedling Base focuses on selective breeding and mass propagation of high-quality Min Gui seedlings.

As the core germplasm source base for Daodi Dong Quai nationwide, the base undertakes germplasm conservation, seed purification, seedling breeding and technical demonstration. Supported by the unique alpine terroir of Min County and standardized nursery protocols, it supplies robust, low-bolting Dong Quai seedlings to major planting regions. All seedlings trace back to certified Min Gui strains, laying a solid genetic foundation for high-quality origin Dong Quai.

1. Germplasm Resources & Technical Strength

1. Preserved germplasm bank Collects and conserves wild Dong Quai communities and improved varieties including MinGui No.1 to MinGui No.6; carries out seed purification, rejuvenation and pelleting treatment to stabilize hereditary traits.
2. Specialized anti-bolting nursery technology Adopts integrated greenhouse cultivation, intelligent temperature & humidity control and substrate seedling raising. Effectively restrains premature bolting, a major industry challenge, and controls bolting rate at a low level.
3. Standardized breeding specifications Follows national technical standards for Min Dong Quai; builds facilities including multi-layer circulating nursery beds, automated sowing lines and seedling sorting systems.
4. Technical cooperation Long-term joint research with agricultural universities and Min County Dong Quai Research Institute to continuously optimize seedling survival rate and stress resistance.

2. Natural Advantages for Dong Quai Seedling Cultivation

Min County’s highland climate creates ideal nursery conditions for Dong Quai seedlings:

• Elevation 2000–3000 m, cool and humid alpine climate, moderate light and large temperature difference between day and night, beneficial for seedling root development.
• Fertile loose black loam, rich in organic matter and trace elements, free from heavy pollution.
• Consistent ecological environment matching the transplanting habitat of adult Dong Quai, so seedlings have strong adaptability after field transplantation, high survival rate and stable growth.

Seedlings cultivated here feature well-developed root systems, vigorous vitality, strong disease resistance, and maintain the inherent high oiliness and high ferulic acid characteristics of authentic Min Gui.

3. Unified Standardized Seedling Production Management

All nursery plots implement whole-process standardized control:

1. Unified parent seeds Only purified certified Min Gui seeds are used; mixed inferior seeds and exotic germplasm are strictly excluded.
2. Unified nursery medium & agronomic management Adopt scientific formula substrate, prioritize organic nutrition, restrict forbidden agrochemicals, produce pollution-free seedlings compliant with export requirements.
3. Stage-based seedling grading Seedlings are sorted by root thickness, bud status and health level to achieve classified supply.
4. Full lifecycle traceability Each batch of seedlings carries traceability information covering seed origin, nursery period, field management and quality inspection.
5. Strict seedling quarantine Prevent spread of soil-borne pathogens to reduce risks after transplantation.

4. Base Scale & Operation Mode

Min County boasts a total medicinal herb seedling breeding area over 75,000 mu. This standardized Dong Quai seedling demonstration base serves as a core nursery hub.

Operational framework: Leading Enterprise + Chinese Medicinal Herb Seedling Base + Cooperatives + Growers.

The base provides standardized seedlings, free technical guidance and after-sale planting support for domestic and overseas growers. High-quality Min Gui seedlings are delivered to planting areas across China, forming a complete upstream germplasm link of the Dong Quai industrial chain.

5. Industrial Significance of Dong Quai Seedling Base

1. Source quality control Seedlings are the “chip” of medicinal herbs. Superior seedlings fundamentally guarantee consistent quality of origin Min Gui.
2. Solve industry bottlenecks Address the pain points of random seed sources, high bolting rate and unstable seedling quality in decentralized cultivation.
3. Support GI industrial system Provide qualified seedlings for Authorized Geographical Indication Dong Quai planting bases, protecting the brand reputation of authentic Min Gui.
4. Demonstration value Build a replicable standardized breeding model for Daodi medicinal herb seedlings on the Loess Plateau.

Conclusion

Relying on Min County’s unmatched natural conditions and mature seedling breeding technology, the Chinese Medicinal Herb Seedling Base is a key germplasm supply platform for authentic Min Gui. By focusing on selective breeding, standardized nursery and germplasm protection, the base guarantees stable supply of premium Dong Quai seedlings, supporting sustainable, high-quality development of the global Min Gui industry.
