促进植物提取技术高效修复镍污染土壤的方法

Study on Efficient Improvement of Phytoextraction of Ni from Contaminated Soil

随着对重金属超富集植物研究的加深,用植物提取技术来改良镍污染土壤已逐步进入实用阶段。在此所探讨的提高此技术功效的方法基于2个方面:提高土壤溶液中镍的浓度,促进植物对镍的吸收;根据已了解的超富集的生理机制可能采取的一些措施。

Phytoremediation has been regarded as a suitable technique for the pollution control of Ni contaminated soils. In this paper two methods of efficient improvement of phytoextraction are discussed： first, to improve the uptake of Ni by plants by increasing Ni concentration in soil solution; second, to adopt some means based on physiological mechanism of heavy metal hyperaeeumulators.
