摘要:
为促进水环境治理，通过水培的方式研究了华北地区常见的9种挺水植物（旱伞草、黄菖蒲、水葱、西伯利亚鸢尾、千屈菜、蒲苇、水生美人蕉、黄花鸢尾和花叶芦竹）对水体中氮磷的净化效果。结果表明：不同植物间株高和地上生物量的变化差异明显，其中水葱株高变化最大，水生美人蕉地上生物量变化最高。9种挺水植物对水中总氮、总磷的去除都有较好的效果，总氮去除效果排序为黄菖蒲>西伯利亚鸢尾>旱伞草>黄花鸢尾>千屈菜≥花叶芦竹>水生美人蕉>蒲苇>水葱>对照组。总磷的去除效果排序为西伯利亚鸢尾>黄花鸢尾≥水葱>黄菖蒲>水生美人蕉>旱伞草>花叶芦竹>千屈菜>蒲苇>对照组。各组植物间单位面积总氮的去除不存在明显差异，总磷的去除差异明显；地上单位生物量的总氮、总磷去除率的变化范围分别为0.50~6.58和0.043~0.455 mg?g-1。考虑到氮磷净化效率及景观效果，西伯利亚鸢尾、黄花鸢尾可作为富营养化水体修复的备选植物。
Abstract:
In order to promot water environment control,nine kinds of water plants including Cyperus alternifolius,Iris pseudacorus,Scirpus tabernaemontani,Iris siberian,Lythrum salicaria L.,Cortaderia selloana,C.glauca,Iris pseudoacorus and Arundo donax var.versicolor,which were common in North China,were studied by means of hydroponics on the purification of nitrogen and phosphorus in water.The result showed that the plant height and aboveground biomass of different plants were significantly different,and the change of Scirpus tabernaemontani′s height was the largest,and the biomass of C.glauca was the highest.Nine kinds of water plants on the water total nitrogen and phosphorus removal had a better effect.The removal efficiency of total nitrogen was as follows:Iris pseudacorus L.>Iris sibirica L.>Cyperus alternifolius>Iris wilsonii C.H.Wright>Lythrum salicaria L.≥Arundo donax var.versicolor>Canna glauca L.>Cortaderia selloana>Scirpustabernaemontani>control group.The removal of total phosphorus were as follows:Iris sibirica L.>Iris wilsonii C.H.Wright≥Scirpus tabernaemontani>Iris pseudacorus L.>Canna glauca L.>Cyperus alternifolius>Arundo donax var.versicolor>Lythrum salicaria L.>Cortaderia selloana>control group.There was no significant difference in the removal of total nitrogen in the plants per unit area,and the removal of total phosphorus was significant.The change of total nitrogen and total phosphorus removal rate per unit aboveground biomass was 0.50-6.58 mg?g-1 and 0.043-0.455 mg?g-1.Considering the efficiency of nitrogen and phosphorus purification and landscape effect,Iris sibirica L.and Iris wilsonii C.H.Wright could be used as alternative plants for the restoration of eutrophic water.
