为了探究不同湿地植物在处理高负荷养猪废水时的根际效应，本研究通过野外小区控制试验，以3种常见的挺水植物美人蕉（Canna indica）、梭鱼草（Pontederia cordata）、黄菖蒲（Iris pseudacorus）为研究对象构建表流人工湿地，研究人工湿地植物根系分泌物与根际氮循环微生物之间的关系。结果显示，梭鱼草对养猪废水的处理效果最好，氨氮、硝氮和总氮的去除率分别为78.3%、93.4%和81.2%。与试验前相比，梭鱼草和黄菖蒲根系可溶性有机碳（DOC）分泌速率在试验后分别增加了44.9%和13.5%；根系总有机酸（TOA）分泌速率分别增加了125.1%和147.5%。在处理养猪废水后，3种植物根际硝化过程氨氧化细菌（...

To explore the rhizosphere effect of different macrophytes during treating high-loaded swine wastewater,we built the surface flow constructed wetlands(CWs)planted with three different types of emergent plants(Canna indica,Pontederia cordata,and Iris pseudacorus).Through a controlled field experiment,the relationships between root exudates and rhizosphere nitrogen cycle-related microorganisms were investigated.The results suggested that the CW planted with P.cordata was more effective in treating swine wastewater,and the removal efficiencies of ...
