Construction method of improved ecological ridge capable of reducing farmland runoff impact and non-point source pollution
The invention discloses a construction method of an improved ecological ridge capable of reducing the farmland runoff impact and the non-point source pollution. The construction method comprises the steps that a ridge body of the ridge is heightened and widened, and the structure and the shape of the ridge are improved; intercepting layers with different functions and effects are arranged in the ridge body of the ridge, specifically, the intercepting layer on the side close to farmland is an iron carbon packing layer, the intercepting layer in the middle is a zeolite layer, and the intercepting layer on the side far away from the farmland is a biological carbon layer; and plants with different ecological functions are grown on the top and the outer side of the ridge, specifically, herbaceous nitrogen and phosphorus enrichment plants and herbaceous soil fixation plants are grown on the top of the ridge, and the herbaceous nitrogen and phosphorus enrichment plants are grown on the outerside of the ridge. By the adoption of the ecological ridge, the farmland runoff can be effectively resisted, and the effects that water and soil are preserved, and leakage of non-point source pollutants is avoided and controlled are achieved; and the non-point source pollutants which laterally seep can be effectively removed, and the effect that the agricultural non-point source pollution is reduced is achieved.
本发明公开了一种削减农田径流冲击和面源污染的改良生态田埂的构建方法，包括：增高和加宽田埂埂体尺寸，改良田埂结构和形状；在田埂埂体中布设具有不同功能作用的拦截层，其中靠近农田一侧的为铁炭填料层，中间的为沸石层，远离农田一侧的为生物碳层；在田埂顶部及外侧部种植具有不同生态功能的植物，其中田埂顶部种植草本氮磷富集植物和草本固土植物，田埂外侧部种植草本氮磷富集植物。本发明所述的生态田埂一方面能够使农田径流得到有效阻滞，起到保持水土，阻控面源污染物外泄的作用；另一方面能够使侧渗面源污染物得到有效去除，起到削减农业面源污染的作用。
