A pot experiment was conducted to study the effects of inoculation with arbuscular mycorrhizal (AM) fungi, neighboring plants (Trifolium repens), addition of EDTA and phosphate fertilizer on the performance of Dianthus superbus grown on Pb contaminated soil. The growth and quality of D. superbus were investigated to provide a theoretical basis for the scientific cultivation of Chinese herbal medicine. The results showed that the D. superbus with AM resulted in a significant inhibition of Pb uptake (P＜0.05), increase of root development and root/shoot ratio compared to untreated control plants, and with the highest content of active component. The content of emodin reached 6.5 mg·g通过盆栽试验研究了接种丛枝菌根真菌(AM真菌)、种植共生植物(三叶草)、添加重金属螯合物EDTA和磷肥磷酸钙对铅污染下瞿麦生长和品质的影响,为科学种植中药材提供理论依据.结果表明: 接种AM真菌可以显著抑制铅的吸收(
