Abstract: To clarify the current status of wild Belamcanda chinensis (L.) DC. resources in the Dabie Mountains of Hubei Province and to construct a systematic conservation technology system, a systematic investigation into the distribution range, resource status, and changing trends of wild Belamcanda chinensis in the region was conducted through years of field surveys, resource collection, and interviews, combined with geographic information and statistical analysis methods. Practical conservation techniques, including the establishment of a germplasm nursery, cultivation management, and new variety selection and breeding, were also implemented. The results showed that wild Belamcanda chinensis was distributed across all 10 counties (cities) of the Dabie Mountains in Hubei Province, involving a total of 93 townships, which accounted for 68.89% of the total number of townships in the region. The resources were mainly sporadically distributed. Compared with the 1980s, the number of townships with distribution had decreased by 13.21%, and both resource density and total quantity had declined by over 90%. A systematic technical system for the conservation of wild Belamcanda chinensis resources was developed, encompassing aspects such as the construction of the germplasm resource nursery, standardized cultivation technology systems, integrated pest and disease control, and the selection and breeding of new varieties. The research findings clarified the distribution pattern and decline trend of wild Belamcanda chinensis resources in the Dabie Mountains of Hubei Province. The proposed conservation techniques could provide technical support for the scientific collection, effective conservation, and sustainable utilization of wild Chinese medicinal plant germplasm resources in this region and similar areas.
