Abstract

The invention discloses a novel ecological farmland drainage trench system. The novel ecological farmland drainage trench system comprises a field ditch, a field furrow and a plurality of ecological furrows, wherein the field ditch and the field furrow are arranged in parallel, the multiple ecological furrows are arranged between the field ditch and the field furrow and are perpendicular to the field ditch and the field furrow. By means of the system provided by the invention, a symbiotic ecological system with a paddy field, an ecological furrow, an ecological slope, aquatic plants, an aquatic vegetable floating bed being integrated can be achieved. The ecology and landscape concepts are introduced on the basis of keeping original flood drainage standard of a drainage trench, and aiming at achieving cultivation and drainage combined ecological agriculture, preventing ecological degradation and non-point source pollution and maintaining biological diversity, the ecological farmland drainage trench system capable of restoring the ecological system, improving surroundings and improving ecological landscape is formed. The farmland ecological system biological diversity and insect attack resisting capacity can be enhanced.

Description

technical field [0001] The invention relates to the technical field of water environment treatment and farmland sewage restoration, in particular to a novel ecological farmland drainage ditch system. Background technique [0002] As an important part of agricultural water conservancy construction, farmland drainage ditches can not only remove waterlogging and drainage in time, but also bring economic benefits to agricultural production. As the connecting zone between farmland pollutants and receiving water bodies of rivers and lakes. Through the adsorption of soil in the drainage ditch, the adsorption of plants in the ditch, and the degradation of microorganisms, the composition and content of pollutants discharged into the water body are changed, which directly affects the health of the ecosystem in the watershed and the balance of the agricultural ecosystem. In addition, the drainage ditch It also has great potential for landscape development. [0003] In recent years, u...
