Abstract

Abstract:

To evaluate the remediation effect of Artemisia argyi on cadmium contaminated cultivated land, and provide reference for the promotion of phytoremediation of cadmium contaminated cultivated land, Artemisia argyi planted in cadmium contaminated cultivated land in Heshan District of Yiyang was selected as the research object. Artemisia argyi and soil samples were collected for detection, and the enrichment coefficient and translocation factor of cadmium in roots, stems and leaves of Artemisia argyi were compared and analyzed. The results showed that the overall distribution characteristics of cadmium content in various organs of Artemisia argyi were stem>leaf>root; the average enrichment coefficient of root, stem and leaf of Artemisia argyi were 2.67, 5.57 and 3.95, respectively, and the average underground to aboveground translocation factor was 3.83; the cadmium content in the soil of Artemisia argyi planted for 3 consecutive years was 0.35 mg/kg lower than that of the surrounding unplanted soil, indicating that Artemisia argyi had strong enrichment and transport capacity for cadmium. Therefore, the application of Artemisia argyi in the remediation of cadmium contaminated cultivated land has great potential.

Key words: Artemisia argyi, cadmium, bioconcentration factor, translocation factor
