Excess nitrogen in agricultural drainage poses a serious threat to the water quality safety of Yellow River basin. Utilizing aquatic plants modify rhizosphere microbial community structure and facilitate transformation is crucial strategy for mitigating regional eutrophication. Our results revealed that denitrification rate (DR), dissimilatory nitrate reduction ammonium (DNRAR) fixation (NFR) sediments exhibited significant increase artificially cultivated ditch. Compared with those natural ditches, richness bacterial relative abundances Bacteroidota, Verrucomicrobiota, Firmicutes, Anaeromyxobacter Geobacter, which are involved mainly cycle, ditch were significantly greater due improvements environmental conditions. In ditch, dominant functional genes affecting DRNARs P. australis nrfC nrfA, while DRs driven by norB napA, influenced carbon levels; NFRs T. orientalis nifD, nifK nifH. provide scientific basis use excess levels drainage.
