外源物质在苎麻修复镉污染土壤中的应用研究进展

Research Development in Application of Exogenous Materials in Remediation of Cadmium Contaminated Soil by Ramie

近年来,中国耕地土壤环境质量问题制约了农业产业的快速发展,镉污染问题尤为突出。苎麻因具有修复镉污染土壤的潜力而备受关注。相关研究表明,外源物质能提高苎麻耐镉能力和镉污染土壤修复效率。文章综述了外源物质在提高苎麻耐镉性、增强苎麻对镉污染土壤修复能力方面的最新研究进展,以及外源物质引起的苎麻相关生理生化响应,以期为利用外源物质增强苎麻耐镉性和提高修复重金属污染土壤效率提供参考。

Recently, the soil pollution severely limits the rapidly development of the agricultural industry in China, especially Cd contamination. It has arisen from the studies on the tolerance to Cd stress by ramie. Current studies suggested that exogenous materials increased the ability of the ramie phytore- mediation to Cd and enhanced the tolerance to Cd. This review describes the newly progress in the mechanism of Cd tolerance and the phytoremediation of Cd contaminated soil, as well as the response to Cd by applying exogenous materials in ramie. This will provide a reference for the researches that improve Cd resistance and the efficiency phytoremediation by ramie.
