几种适合在红河州生态混凝土中生长的草本植物对重金属的富集
Ability of Heavy Metal Concentration of Several Herbs Suitably Growing on Eco-concrete in Honghe Prefecture
摘要
Abstract
In order to determine herbs which can grow well in eco-concrete and can help us to restore environment , we select nine kinds of herbs according to the characters of climate and soil in Honghe prefecture of Yunnan Prov -ince .Then, we plant these herbs using the construction technology of eco-concrete and analyze the concentrations of <br> heavy metals, including Pb, Zn, Cu, Cr, Hg and Cd.Experimental results show that: (1) Cynodon dactylon , Vetiveria zizanioides L., Carex‘Evergold’ has the highest ability of enriching Pb , Zn, Hg, and Commelina commu-nis has the highest ability of enriching Cu , Cr, Cd;(2) average concentration coefficient of heavy metal of Com-melina communis is the highest, followed by Bidens pilosa L., Carex ‘Evergold’, Vetiveria zizanioides L., Ophio-pogon bodinieri, Cyperus rotundus, Cynodon dactylon, Nephrolepiscordifolia( L.) Presl and Canna indica L.In these herbs, average bioconcentration coefficients of heavy metal of Commelina communis, Bidens pilosa L.and Carex‘Evergold’ are all bigger than 1.In comprehensive consideration of the herbs ’ ability of enriching heavy metals and the conditions of growing in eco-concrete, we decide that Commelina communis and Vetiveria zizanioides L.are the most suitable for eco-concrete engineering among the nine kinds of herbs .关键词
