| 摘 要： | 采用盆栽试验,研究乙二胺四乙酸二钠(EDTA)辅助下,科源油2号油菜修复铅、镉单一污染土壤的效果.在本实验条件下,EDTA的最佳投加量为5.0 mmol·kg-1时,油菜Pb、Cd吸收量分别达到1 542 mg·kg-1和64 mg·kg-1.该结果表明,EDTA辅助下可显著增强油菜对Pb、Cd的吸收累积,EDTA在诱导油菜修复Pb、Cd污染特别是Pb污染土壤方面具有很大的潜力.

| Abstract: | A pot experiment was conducted to investigate the potential of rape(Brassaca napus.L) for phytoremediation of Pb,Cd single contaminated soil by the ai<1 of EDT A.The best repairing efficiency was observed in the treatment of applying 5.0 mmol·kg-1 EDTA to the soil in this study,the total uptake amount of Pb,Cd by rape(Brassaca napus.L) reached 1 542 and 64 mg·kg-1 respectively.The results showed that the application of EDTA to the soil significantly incxeased the uptake amount of Pb,Cd by rape(Brassaca napus.L).It is indicated that,the EDTA could be regarded as a good chelate candidate for rape(Brassaca napus.L) phytoextract Pb,Cd pollution,particularly for Pb in corr terminated soils. |
