摘要	Developing strategies for concurrently exploiting and remediating heavily Cd contaminated soils is vital in areas with inadequate arable land supply and severe pollution. To study the impact of various nano-hydroxyapatite (NHA) concentrations on the yield and quality of Erigeron breviscapus, as well as the remediation effect on severely Cd-contaminated soil, four concentrations of NHA (0, 5, 10, and 20 mg kg -1 NHA for CdA0, CdA5, CdA10, and CdA20) were added to Cd-contaminated soil (100 mg kg - 1). Soils polluted with Cd and NHA were absent from the treatment control (CK). We found that compared with CdA0, E. breviscapus yield increased by 60% in CdA20, scutellarin concentration increased by 190.1-244.9% in CdA5, CdA10, and CdA20, and soil Cd content decreased by 14.2% in CdA20. Additionally, CdA20 had a greater impact on improving E. breviscapus yield and quality while lowering soil Cd content. Structural equation modeling and principal component analysis showed that increased net photosynthetic rate, chlorophyll content, catalase activity, and phosphorus content and decreased malondialdehyde and soil available Cd content were all driving factors in E. breviscapus growth. This study suggests a potential technique for utilizing and repairing severely Cd-contaminated soils by coupling E. breviscapus cultivation with NHA application.
