摘要
对两种不同地域的野生东南景天进行了分析。发现不同地域的东南景天在重金属积累性上存在显著差异。姚王矿区东南景天生物量约是上台门矿区的4倍。姚王矿区东南景天地上部分积累Zn最高达7850 mg/kg,上台门矿区东南景天为1623 mg/kg。积累Cd最高达到222mg/kg,上台门为37.5 mg/kg。对Pb的积累,两种景天都主要聚集在根部。对Cu的积累表现为正常植物水平。
Sedum alfredii Hance from two different areas were researched in this study. The major results are as follows: Sedum alfredii from Yaowang Pb/Zn mine metal uptake ability is higher than Shangtaimen Pb/Zn mine. The highest Zn was found in Yaowang Sedum alfredii , reached 7850mg/kg, Shangtaimen reached 1623 mg/kg. The highest Cd was found in Yaowang Sedum alfredii , reached 222mg/kg, Shangtaimen reached 37.5 mg/kg. Both Sedum alfredii's major uptake Pb are in root, and uptake ability Cu is the same to common plant.
