| Ramie has high biomass, can be harvested many years at one seeding, it is good for heavy metals remediation as well as economic efficiency, which is regarded as a kind of ideal resource in phytoremediating soil contaminated by heavy metals. This paper summarized the research progress in ramie remediation of heavy metals in recent years, pointed out that ramie could accumulate heavy metals, the ability of heavy metal accumulation was different to each metal ions, ramie was useful for remedy of single and combined heavy metals pollution, which could be used as phytoremediation plant resources. Summarized the measures to further strengthen the repair ability of ramie, elaborated five aspects effecting ramie enrichment and distribution of heavy metal process, which were variety, soil improvement agent,chemical regulation, agronomic measures and soil microbial. Discussed the ability, measures, mechanism of ramie enrichment and heavy metal tolerance, and finally put forward suggestions and prospects on the current problems. |
