摘要: 分析了湖南湘潭锰矿矿区内受尾渣污染的土壤,以及生长于污染土壤的9种植物样对Mn、Pb、Cd的吸收与富集能力。结果表明,早熟禾、鼠麴草、蕨、和商陆对Mn有较强富集能力,同时也是Mn的耐性植物;早熟禾、鼠麴草以及蕨对Pb的吸收和富集能力较强;小飞蓬、早熟禾和麴草对Cd的富集能力较强;但是各种植物对这3种重金属的富集能力均未达到超富集植物的要求,进一步的改良栽培实验仍在研究中。

Abstract: Asurvey of soils and ten plants growing on the soil polluted by Manganese mine tailings in Xiangtan city was conducted.Analysis result indicated that the exceptional-high concentrations of Mn was found to be the limiting factor for plant growth. The concentrations of Mn, Pb, and Cd in the ten plants and Mn-enrichmentalabilities of the ten plants were analyzed in this paper.Poa pratensts, Gnaphalinm affine, Pteris viltata L., and Phytolacca esculenta Van Houtte were proved to have good metal-enrichmental and Mn-tolerant ability. Poa pratensts, Gnaphalinm affine and Pteris viltata L.were Pb-tolerant plants. Comnyza Canadensis (L.) Cronqs, Poa pratensts, and Gnaphalinm affine were Cd-tolerant plants. However, no hyperaccummulators of these three heavy metals were found in the survey. Further research on improved culture experements were still in process.
