【摘要】 籽粒苋是一种生长速度快、生物量大、适应性强、营养成分高、易栽培的超富集植物,具有良好的修复重金属污染土壤的潜力。笔者简述了籽粒苋的特性、栽培管理、利用价值,总结了近年来籽粒苋富集重金属镉、铯、铊等及与籽粒苋相关的联合修复重金属污染土壤技术(添加剂、微生物、动物、农艺措施)的研究进展,探讨了籽粒苋修复土壤重金属污染的存在问题及今后提高修复土壤重金属污染效率的方法,以期为籽粒苋在土壤重金属污染修复的应用提供理论参考。更多还原

【Abstract】 Amaranthus hypochondriacus is a kind of hyperaccumulator with fast growth, large biomass, high adaptability and high nutrient content, which is easy to be cultivated. It has good potential for remediation of heavy metal contaminated soil. This paper briefly described the characteristics, cultivation management, and the application value of A. hypochondriacus, summarized recent research progress of A. hypochondriacus on soil heavy metal accumulating cadmium, caesium, thallium, and combined remediation technology(additives,microorganisms, earthworms, agronomy measures). The existing problems of A. hypochondriacus in remediation of heavy metal pollution in soil and the methods for improving the remediation efficiency of A. hypochondriacus were also discussed, to provide theoretical reference for the application of A. hypochondriacus in remediation of heavy metal pollution in soil.更多还原
