摘要: Abstract In this study, Myriophyllum elatinoides growth under different nitrogen (N) concentrations (2, 250, 300, 350 and 400 mg L−1) changes in rhizosphere bacterial community structure were investigated. High N (>300 mg L−1) caused reduction M. biomass. Growth tended to stabilize at 49 days. concentration roots higher than that stems leaves high conditions. TN NH4+ removal efficiencies reached 84.0% 87.2%, respectively, surface flow constructed wetlands (SFCWs). Rhizosphere diversity increased over time. Proteobacteria, Firmicutes, Cyanobacteria, Bacteroidetes dominated the phylum level. Genera Turicibacter, Allochromatium, Methylocystis low (
