摘　　要：为探明杜鹃花修复重金属污染土壤的可行性,采用盆栽杜鹃花试验,将种植5个月后的杜鹃花植株进行焚烧处理制成灰分,将种植杜鹃花前后的土壤制成样品,参照GB/T 17138—1997、GB/T 22105—2008、GB/T 17141—1997分别测定土壤和植株灰分中重金属Zn、As、Pb和Cd的含量。结果表明,杜鹃花能够吸收土壤中的Zn、Pb、Cd和As,尤其是对Zn和Pb具有较强的吸收能力,说明杜鹃花能够修复重金属Zn和Pb污染的土壤。In order to explore the feasibility of remediation heavy metal contaminated soil by Rhododendron simsii Planch,the experiment of potted Rhododendron simsii Planch was conducted. After planting for five months,the plants of Rhododendron simsii Planch were incinerated to form ash,the soil before and after the planting of Rhododendron simsii Planch was made into the sample. The content of heavy metals such as Zn,As,Pb and Cd in soil and the plant ash was determined respectively according to GB/T 17138-1997,GB/T 22105-2008 and GB/T 17141-1997. The results showed that Rhododendron simsii Planch could adsorption Zn Pb,Cd and As in soil,especially had a strong adsorption capacity for Zn and Pb,and indicated that Rhododendron simsii Planch could remediate the heavy metal contaminated soils by Zn and Pb.
