抗污染园林植物的选择

Choice of Pollution-resistant Garden Plants

在盆栽试验的基础上研究了瞿麦、鸢尾、葱兰、吉祥草和垂盆草对铜、镉、铅的响应。研究结果表明,瞿麦对镉污染土壤修复效果显著,吉祥草对铜污染土壤修复效果最好,垂盆草对铅污染土壤修复效果最好;在多种重金属污染的土壤里,瞿麦修复效果最好,其次为垂盆草、吉祥草和鸢尾,最差的是葱兰。

This paper deals with the response of Dianthus superbus Linn , Iris tectorum Maxim , Zephyranthes candida(Linndl.)Herb.,Reineckia carnea(Andr.)Kunth and Sedum sarmentosum Bunge to copper, cadmium, plumbum on the basis of tests conducted in pots . The result of the study indicates that Dianthus superbus Linn produces a remarkable repairing effect on the soil that is polluted by cadmium , that Reineckia carnea(Andr.)Kunth produces the greatest repairing effect on the soil that is polluted by copper and that Sedum sarmentosum Bunge produces the greatest repairing effect on the soil that is polluted by plumbum . It also shows that , in the soil which is polluted by of heavy metals, Dianthus superbus Linn produces the greatest repairing effect; Sedum sarmentosum Bunge, Reineckia carnea(Andr.) Kunth and Iris tectorum Maxim come second; and Zephyranthes candida(Linndl.)Herb produces least effect .
