摘要
通过盆栽实验,研究了美人蕉在镉污染土壤中的生长特征及对镉的吸收规律和修复能力。结果表明,在土壤中含镉质量浓度为0～5mg/kg时,美人蕉生物量有小量上升。随时间延长和土壤镉浓度增大,镉对美人蕉生长的抑制程度增强。美人蕉对镉的富集规律表现为根>茎>叶。在含镉5mg/kg的土壤中生长2个月,美人蕉可从土壤中带走的镉量为3.60t/(hm2·月)。美人蕉适合种植于低浓度污染土壤,在镉污染环境的修复方面具有良好的应用前景。
In this paper, experiments are done to make studies on canna generalis in cadmuium pollution soil, including growing charactefisties, absorption rules and remedy ability to cadmuium. The results show that when canna generalis is planted in low concentration of poUution soil, it does well in remedy of cadmuium pollution environment.
