摘要:

为评估艾蒿对镉污染耕地的修复效果,并为镉污染耕地的植物修复推广提供参考,本研究以益阳赫山区的镉污染耕地种植的艾蒿作为研究对象,采集艾蒿和土壤样品进行检测,对比分析了艾蒿根、茎、叶对镉的富集系数和转运系数。结果显示:艾蒿各器官镉含量总体分布特征为茎>叶>根;艾蒿根、茎、叶的平均富集系数分别为2.67、5.57、3.95,地下向地上平均转运系数为3.83;连续种植3 a后,种植艾蒿的土壤镉含量比周边未种植的土壤平均降低0.35 mg/kg。艾蒿对镉有较强的富集和转运能力,表明其在镉污染耕地修复方面具有巨大潜力。

关键词: 艾蒿, 镉, 生物富集系数, 转运系数

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.
