本发明公开了种处理农田排水水质的生态试验系统，包括人工生态沟渠、人工湿地和用于排水的排水渠，人工湿地包括多级集水区和配水渠，每级集水区底部与其前的配水渠之间设有带第二控制阀门的混凝土管道，每级集水区与其相邻两侧的配水渠之间通过混凝土墙隔离，每级集水区与其前的配水渠之间混凝土墙比其后的混凝土墙高；第级集水区前的配水渠为进水渠，最后级集水区后的配水渠为退水渠，进水渠与所述人工生态沟渠尾端相连，退水渠与排水渠相连，人工生态沟渠包括渠顶、渠壁、渠底和竹笼石，其横断面形状为梯形，本发明经济可靠、节约用地，通过生态沟渠与人工湿地系统配合协调减少N、P排放量、提高农田排水水质处理效率。 The invention discloses an ecological test system for treating farmland drainage water quality. The ecological test system comprises an artificial ecological channel, a piece of artificial wet land and a drainage channel for draining water, wherein the artificial wet land comprises multiple levels of water collection areas and water distribution channels, a concrete pipeline with a second control valve is arranged between the bottom of each level of water collection area and the water distribution channel in front of the water collection area, each level of water collection area is isolated from the adjacent water distribution channels at two sides by virtue of a concrete wall, and the concrete wall between each level of wat
