| 苎麻生物量大，一年播种多年收获，修复重金属同时具有一定的经济效益，被认为是一种重金属污染土壤的理想修复植物。综述了近年来学者们在苎麻修复重金属方面所取得的研究成果，指出苎麻对多种重金属具有一定的富集作用，对不同种类的重金属离子富集能力有差异，对单一和复合重金属污染土壤均具有一定的修复能力，能作为植物修复中可利用的植物资源。重点对进一步强化苎麻的修复能力的措施作了总结，阐述了影响苎麻富集和
分配重金属过程的5 个因素院品种、土壤改良剂、化学调控、农艺措施及土壤微生物，探讨了苎麻富集和耐受重金属的能力和机理，并就存在的问题提出建议和展望。 |
| 英文摘要: |
| 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. |
