摘要:
通过对黑麦草、玉米草、苏丹草、狼尾草、紫花苜蓿、白三叶草6种植物在不同浓度镉离子溶液中发芽率的测定,以及6种草生长状况的观察,选择发芽率较高、生长良好的黑麦草、玉米草、苏丹草、狼尾草作为修复重金属镉离子污染土壤的植物。通过比较4种植物在不同浓度镉离子污染土壤中的生长状况及去除率发现,当土壤中的镉离子含量为25 mg/kg时,黑麦草对镉离子的去除率最高,达到79%,但是随着土壤中镉离子浓度的升高,去除率逐渐下降,最后不到20%。玉米草对镉离子的去除率先升后降;苏丹草对镉离子的去除率大致稳定在60%左右;当土壤中镉离子含量为75~100 mg/kg时,狼尾草对镉离子的去除率较高,并且一直稳定在75%左右。因此,目前认为狼尾草、苏丹草对镉离子有很好的耐受能力,可以用于镉离子污染土壤的修复。
