Rice field nitrogen and phosphorus non-point source pollution vegetation composite interception system and application thereof
The invention provides a vegetation composite interception system for rice field nitrogen and phosphorus non-point source pollution and application of the vegetation composite interception system, and belongs to the technical field of agricultural non-point source pollution treatment and environmental protection. The vegetation composite interception system comprises a collecting channel (1), a vegetation filter strip (2) and an interception channel (3), ecological slope protection is adopted for the side slope of the collecting channel (1), and juncus roemerianus and typha angustifolia aquatic plants are planted at the bottom of the channel. A ryegrass planting belt and a ophiopogon japonicus planting belt are sequentially arranged in the vegetation filter belt (2), and the belt width ratio of the ryegrass planting belt to the ophiopogon japonicus planting belt is 2: 3; and a fine sand layer, a coarse sand layer, a gravel layer and a pebble layer are sequentially filled in the interception channel (3) from top to bottom. According to the vegetation composite interception system for farmland non-point source pollution, nitrogen and phosphorus pollutants in agricultural rice fields can be efficiently intercepted and removed, the occupied area is small, the construction cost is low, and the maintenance period is long.
本发明提供了一种稻田氮磷面源污染的植被复合拦截系统及其应用，属于农业面源污染治理及环保技术领域。本发明的植被复合拦截系统包括集流渠(1)、植被过滤带(2)和截留渠(3)；所述集流渠(1)边坡采用生态护坡，渠底种植灯芯草和蒲草水生植物；所述植被过滤带(2)内依次设置有黑麦草种植带和麦冬草种植带，黑麦草种植带与麦冬草种植带的带宽比为2：3；所述截留渠(3)内自上而下依次填充有细砂层、粗砂层、碎石层和卵石层。本发明提供的农田面源污染的植被复合拦截系统能够实现对农业稻田中的氮和磷污染物进行高效拦截和去除，且占地面积小、建设成本低、维护周期长。
