通过在宁夏石咀山市惠农区永固乡不同灌溉制度条件下的不同矿化度微咸水灌溉试验 ,研究了微咸水灌溉的土壤含盐量的动态变化规律 ,在正交试验的基础上得出了适合当地条件的并有利于作物生长发育及对土壤改良有益的微咸水灌溉制度 ,为有微咸水灌溉条件的干旱地区提供了农业持续发展操作性较强的灌溉制度 Through the experiment of brackish water with different salinities under different irrigation regimes in Yonggu Township, Huinong District, Ningxia Shizuishan City, the dynamic changes of soil salt content under brackish water irrigation were studied. In the orthogonal experiment On the basis of this, we have come up with a brackish water irrigation system that is suitable for local conditions and is beneficial to crop growth and development and beneficial to soil improvement. It provides an irrigation system with sustainable operation and development for the arid areas with brackish water irrigation conditions
