黄河水含沙量大,推广滴灌技术滴头常堵塞问题难以解决。通过对宁夏典型滴灌工程水源中泥沙组成及其在泥沙处理系统中各环节泥沙含量的监测,分析泥沙处理系统不同阶段的泥沙组成及处理效果,并对现有工程设计的合理性进行评估,为节水灌溉工程规划设计提供参考。
The Yellow River has a large amount of sediment and sediment, and it is hard to solve the problem of often dripping drip irrigation technology. Through the monitoring of the sediment composition in the source of typical drip irrigation project in Ningxia and the sediment concentration of each stage in the sediment treatment system, the sediment composition and treatment effect in different stages of the sediment treatment system are analyzed. The design of the existing project is reasonable Evaluation of sex, water-saving irrigation project planning and design provide a reference.
