摘要
A rural landscape-type nitrogen and phosphorus ecological interception ditch system and a farmland drainage nitrogen and phosphorus interception method using the system are provided. The system includes a sediment buffer zone, an ecological ditch unit, an interception-conversion pool and a field ridge hedge fence; the sediment buffer zone, the ecological ditch unit, and the interception-conversion pool are sequentially arranged in a continuous ditch along a direction of a water flow; and the field ridge hedge fence is arranged on field ridges on one side or both sides of the ditch. The present disclosure can, on the basis of not affecting normal production functions of a farmland, further exert an ecological role of the farmland, and use the farmland as an assimilation sink for environmental nitrogen and phosphorus, so as to optimize drainage water quality and improve a farmland ecological environment.
