香薷属植物在重金属修复中的应用进展

Progresses on phytoremediation of heavy metal contaminated soils using Elsholtzia plants

摘要:

香薷属植物应用于重金属修复经历了矿区植物资源调查和比较、室内模拟研究、田间规模修复以及修复后处置研究，已经初步形成一个植物修复技术的完整体系。在现有技术条件下，把生态修复模式、品种驯化及诱导剂“配方”应用到香薷属植物修复土壤重金属污染对提高修复效率具有重要意义。

Abstract:

The application of Elsholtzia plants to the phytoremediation of soils contaminated by heavy metals has experienced a series of processes, i.e. plants resource survey and comparison, pot simulation study, field remediation experiments and disposals of after phytoremediation, then formed a complete remediation system. Under current biotechnology, it is important for the higher phytoremediation efficiency by Elsholtzia plants: 1) to rehabilitate pollution sites by several life-forms as a three-dimensional ecosystem, 2) to screen Elsholtzia plants with stable genotype of high accumulation of more heavy metals, and 3) to optimize combination between chemicals and microorganisms for heavy metal accumulation in plant shoots.
