Heavy metal pollution in soil poses a serious threat to the growth of plants used in traditional Chinese medicine. Therefore, a pot experiment was conducted to study the effects of various soil remediation methods on the performance of Herba Dianthi (Dianthus superbus L.) grown on Pb-contaminated soil. The results show that inoculation of Herba Dianthi with arbuscular mycorrhizal fungi (AMF) led to a significant reduction in Pb uptake (P< 0.05), and increased root development and root-to-shoot ratio compared to untreated control plants, along with the highest content of active components. When planting with Trifolium repens, the reduction effect of Pb absorption was insignificant. Herba Dianthi showed improved growth and active ingredients, and the lowest Pb content, with AMF inoculation. The addition of EDTA decreased the growth of Herba Dianthi, but promoted the absorption of Pb. The inhibition of tumor cells was highest in E2. In conclusion, inoculation with AMF can ensure that plant lead content meets testing standards, helping to improve the quality of medicinal herbs.
土壤中的重金属污染对中药材的生长构成严重威胁。因此，进行了盆栽实验，以研究各种土壤修复方法对受 Pb 污染土壤上生长的瞿麦（Dianthus superbus L.）性能的影响。结果表明，丛枝菌根真菌（AMF）接种显著降低了 Pb 的吸收（P<0.05），与未处理的对照植物相比，根系发育和根冠比增加，同时活性成分含量最高。与三叶草（Trifolium repens）一起种植时，Pb 吸收的减少效果不明显。AMF 接种可提高瞿麦的生长和活性成分，同时降低 Pb 含量。添加 EDTA 会降低瞿麦的生长，但会促进 Pb 的吸收。E2 对肿瘤细胞的抑制作用最高。总之，接种 AMF 可以确保植物铅含量符合检测标准，有助于提高中药材的质量。
