In order to solve this problem, this experiment adopts the Yang herb that has a high nutritional value and economic value of plants for heavy metal lead and cadmium pollution after the study experiment with pH value of 4.79 quaternary yellow soil and Yang grandiflorum used as material, potted plant experiment, the indoor combination of chemical analysis and biological statistics method. The results show that the heavy metal lead and cadmium in Yang herb are widely distributed: root, stem and leaf. The maximum number of accumulated heavy metal lead in the Yang herb is 446.03 mg/kg, the largest accumulation of cadmium in the Yang herb quantity is 11.23 mg/kg and heavy metal has an impact on Yang herb to absorb nutrients, heavy metals also have a certain poison on Yang herb; leaf form, the contents of chlorophyll and study of poisoning are preliminary in this experiment, to under-stand the whole process of poisoning mechanism and also to a detailed analysis of the research.
