摘要
[目的]了解香根草、印度芥菜、水蜈蚣、蜈蚣草4种植物修复土壤重金属的潜能。[方法]通过盆栽试验,研究了香根草、印度芥菜、水蜈蚣、蜈蚣草4种植物在重金属污染土壤中的生长特性。[结果]印度芥菜、水蜈蚣、蜈蚣草对土壤中汞、铅、镍有一定的积累能力。[结论]该研究可为"超富集植物"清除土壤重金属提供依据。
[Objective]The research aimed to understand the potential of Vetiveria zizanioides,India Brassica juncea,Kyllinga brevifolia and Pteris vittata.[Method] Growing characteristics of several plants such as Vetiveria zizanioides,India Brassica juncea,Kyllinga brevifolia and Pteris vittata in heavy metals pollution soil was studied by pot experiments.[Result]India Brassica juncea,Kyllinga brevifolia and Pteris vittata were capable to accumulate lead,mercury and nickel.[Conclusion] The research could provide the basis for the heavy metal removal of hyperaccumulators.
