Purple soil hilly area high-standard terraced field rainwater collection and storage method and application
The invention discloses a purple soil hilly area high-standard terraced field rainwater collection and storage method and application, and relates to the technical field of rainwater collection and storage water conservancy projects. Aiming at the problems of shallow soil layer, poor soil water retention capacity, serious water and soil loss and the like of the purple soil hilly area slope cropland, the interflow intercepting and guiding effects of the gridding rock ridges are combined with the collection and storage effects of a slope surface collection and storage system, so that sufficient collection of slope surface moisture is ensured; finally, a high-standard terraced field slope protection and rainwater collection and utilization system with gradient and gridding cooperative retaining of slope surface runoff and interflow as a means is formed, so that the yield of main grains and important agricultural products in purple soil hilly areas due to drought and waterlogging is effectively guaranteed, and the yield is stable and high; and the effects of preventing the loss of nitrogen and phosphorus in soil and reducing non-point source pollution can be achieved through the retaining function of the system.
本发明公开一种紫色土丘陵区高标准梯田雨水集蓄方法及应用，涉及雨水集蓄水利工程技术领域。本发明针对紫色土丘陵区坡耕地土层浅薄、土壤保水能力差、水土流失严重等问题，本发明将网格化岩埂的壤中流拦截、引导作用与坡面集蓄系统的收集存储作用联合起来，保证坡面水分充分收集，最终形成以坡面地表径流、壤中流的梯级化和网格化协同拦蓄为手段的高标准梯田坡面防护和雨水集蓄利用体系，在有效保障紫色土丘陵区主要粮食和重要农产品旱涝保收、稳产高产的同时，又能通过该体系的拦蓄功能起到防止土壤氮磷流失，减轻面源污染的作用。
