Abstract:

引种了2种陆地湿生的耐寒植物——黄菖蒲和西伯利亚鸢尾作为生态浮床植物,以水生美人蕉为对比,进行了水质改善实验研究。在6个月实验期内,黄菖蒲、西伯利亚鸢尾和美人蕉(5个月)对SRP的平均去除速率分别为79.27、20.92和34.29mg/(m2·d),对TP的平均去除速率分别为86.92、24.91和36.6mg/(m2·d),对NH+4-N的平均去除速率分别为517.54、170.57和274.07mg/(m2·d),对TN的平均去除速率分别为763.79、301.81和384.04mg/(m2·d)。黄菖蒲年去除磷的量21207.64mg/(m2·a),是西伯利亚鸢尾的2.6倍,是美人蕉的3.8倍;年去除氮的量186365.78mg/(m2·a),是西伯利亚鸢尾的1.9倍,美人蕉的3.2倍。黄菖蒲和西伯利亚鸢尾耐寒能越冬,生长期长,管理工作量小。
