我国的淡水资源不足,农田灌溉水利用率低,已严重影响农业发展。农业节水是当务之急,也是长远之计。节水技术主要是减少输水损失,减少灌溉水量,减少农田水分损失,提高水分增产率,提高作物产量。一、工程节水技术1、蓄水工程。按照地形、土质、集流方式以及蓄水用途选择适宜的类型。有适宜的低洼地形,且主要用以拦蓄沟岔或蓄存坡面和土路面等含泥沙量较大的雨水时,宜选用涝池和塘坝形式;
The lack of freshwater resources in our country and the low irrigation water utilization rate have seriously affected the development of agriculture. Saving water in agriculture is a top priority and a long-term solution. Water-saving technologies are mainly to reduce water losses, reduce irrigation water, reduce farmland water loss, increase water yield, and increase crop yields. First, the project water-saving technology 1, water storage project. According to the topography, soil quality, flow collection methods and the use of water to choose the appropriate type. Suitable low-lying terrain, and mainly used to save the switch or storage slopes and soil pavement and other heavy sediment containing rainfall, should use the form of flood ponds and ponds;
