The massive loss of nitrogen (N) and phosphorus (P) from farmland ditches contributes to non-point source pollution, posing a significant global environmental challenge. Effectively removing these nutrients remains difficult in intensive agricultural systems. To address this, novel composite ecological ditch system (CEDS) was developed by modifying traditional drainage integrate grit chamber, zeolite, floating beds. Dynamic monitoring N P levels water, plants, zeolite conducted evaluate the system’s nutrient interception performance mechanisms. results showed following: (1) Water quality improved markedly after passing through CEDS, with concentrations decreasing progressively along flow path. intercepted 41.0% 31.9% P, inorganic particulate as primary forms loss. (2) Zeolite removes primarily ion exchange, likely chemical reactions, maximum capacities 3.47 g/kg for 1.83 P. (3) Ecological beds hydroponic cultivation enhanced uptake roots Canna indica Iris pseudacorus, surpassing (4) Nutrient efficiency positively correlated temperature, inlet concentrations, rice runoff but negatively precipitation. This study demonstrates CEDS’s potential improving water suggests further enhancements design management increase its economic aesthetic value.

The global issue of ecological ditches being poor in removing nitrogen and phosphorus under cold winter temperatures has been identified. This study introduced three types biochar (reed, rice, corn) into ditch sediments via two application methods: rhizosphere mixed addition. purpose was to explore how these methods affect the removal phosphorus, as well their influences on microbial communities sediments. results indicated that addition significantly enhanced phosphorus. Among biochar, corn yielded greatest results, achieving rates 77.1% for total (TN), 93.3% NH4+-N, 90.3% (TP). growth Vallisneria natans greatly improved by method, resulting an average increase 154%. improvement superior group, which led a 125%. In comparison, control group (CK) showed decrease 4.8% growth. Different resulted changes physicochemical properties stoichiometry plants. Microbial analyses reduced diversity abundance substrate community.
