摘要/Abstract

摘要： 调查分析了广西大新县锰矿污染的部分土壤及9种优势耐性植物对Mn、Zn、Ni的富集和吸收能力。其中,蜈蚣草对Mn、Zn、Ni有较强的吸收能力;五节芒、野茼蒿、酸模叶蓼、加拿大蓬对Mn的吸收较强;蔓生莠竹、马唐、海芋对Zn吸收较强;而五节芒、加拿大蓬对Ni亦有较强的吸收能力。虽然这些植物对三种重金属的吸收均未达到超富集植物的要求,但作为污染土壤上的优势耐受性植物仍具有一定的意义。

关键词: 锰矿, 植物修复, 金属耐性植物, 超富集植物

Abstract: A survey of nine plants growing on the soil polluted by manganese mine in Daxin County, the Guangxi Zhuang Autonomous Region was carried out.The results indicated that the exceptional-high concentration of Mn was the most important limiting factor for plant growth among three metals (Mn, Zn and Ni).Pteris vittata, which roots showed good metal-enrichment of Mn and Ni, was turned out to have good tolerant ability of Mn, Zn and Ni according to the analysis in the paper.Miscanthus floridulus, Erigeron bonariensis, Polygonum lapathifolium and Erigeron canadensis were proved to have good Mn-tolerant ability.Microstegium gratum, Digitaria sanguinalis and Alocasia macrorrhiza were Zn-tolerant plants while Miscanthus floridulus and Erigeron canadensis were Ni-tolerant plants.Further researches which are of some significance to these plants will be still in process though hyperaccummulators of three heavy metals were not found in these plants.

Key words: manganese mine, phytoremediation, metal-tolerant plant, hyperaccumulating plant
