摘要
采用野外现场试验的方法,研究了芦苇、香蒲、菖蒲、睡莲、水葱、梭鱼草等6种大型水生植物对富营养水体中氮、磷的去除效果。结果表明,水葱和菖蒲对氮、磷的去除效果最好。特别是水葱移栽后易于成活,且适应能力强,值得工程广泛推广。试验还发现,睡莲的生长速度很快,但茎叶脱落后会影响水质。此外,香蒲对藻类的抑制作用明显劣于其他植物。
Six macrophyte species （Phragmites communis, Typha angustifolia, Acorus calamus, Nymphaea tetragona, Scirpus validus, and Pontederia cordata） were grown in eutrophic ponds in order to test their removal efficiency for nitrogen and phosphorus, respectively. Among the six plants, Scirpus validus and Acorus calamus showed the highest removal efficiency, especially for Scirpus validus, it was worth to be applied in water treatment for its good adaptability. Nymphaea tetragona grew rapidly, but its stems and leaves could pollute water body after they fall off. Typha angustifolia showed the least efficiency in algae inhibition.
