The invention discloses an irrigation terraced field design with the ecological idea, and relates to the technical field of agriculture. The irrigation terraced field design comprises the steps of the improving design of a terraced field face for improving the sediment interception effect, the improving design of an irrigated area with the functions of water saving, non-point source pollution preventing, sediment intercepting and plantation structure adjusting, and the design of an area landscape reflecting the terraced field farming landscape and new countryside features. According to the technology, the river sediment originally added through terraced field irrigation is completely stopped in the irrigation area through the double sediment interception effects from the terraced field face to the irrigation area, the irrigation water utilization rate and the farmland surface source pollutant reduction rate can be increased to more than 90 percent through the irrigation area improvement, the new countryside features of the semiarid plateau water and soil loss area are designed by integrating the terraced field planting structure and the leisure agriculture, and the ecological idea is implemented through the design in three aspects including the terraced field face, the irrigation area and the area.
Description
technical field [0001] The invention relates to the field of agricultural technology, in particular to an irrigation terrace layout method under the ecological concept. Background technique [0002] The area where irrigation can be realized in the soil erosion area in my country is mainly the semi-arid plateau area, which belongs to the fourth sub-region of water and soil conservation, that is, the transition area between the Loess Plateau and the Qinghai-Tibet Plateau. The ecological environment in this area is fragile, water resources are short, and the agricultural output is low. The transformation of slopes into terraces is the main project to improve food self-sufficiency in this area. [0003] Existing terrace irrigation engineering design technology: [0004] (1) Field Design Technology for Irrigated Terraced Fields [0005] ①Field water inlet and outlet ditch. Maoqu is a temporary field channel that draws water from agricultural canals and supplies water to furrow...
