| 摘 要： | 采用盆栽试验方法,研究了薄荷、美女樱、羽扇豆3种花卉对铅污染土壤的修复能力,测定了3种花卉不同部位铅浓度对铅的转移和富集系数。结果表明,3种花卉中美女樱地上部吸收富集铅的量最大,积累铅能力最强,其次为薄荷,羽扇豆吸收积累铅能力最弱。在铅浓度为1000mg/kg时,美女樱和薄荷耐性较强,可用作铅污染土壤的稳定修复植物。

| Abstract: | In order to find out suitable ornamental plants for reclaim the Pb contaminated soil,3 flower plant were selected o study heir Pb absorbing characteristics and their Pb tolerance by pot experiment.The results showed that Verbena hybrida had the strongest capability of accumulating Pb in shoot and it was followed by Mentha and Lupinus polyphyllus .Verbena hybrida and Mentha haplocalyx showed stronger tolerance to Pb, which could be used for soil remediation. |
