Groundwater depth has a significant impact on salinization in irrigated areas. In this study, different groundwater depths were controlled via pit tests and we conducted with (DGWs) to investigate the relationship between irrigation water volume salt migration during crop growth period, as well influence of DGW maize yield. The aim study was determine an appropriate for Hetao Irrigation District, largest area Asia, under dual goals conservation control. results showed that upward replenishment 179.60 mm, 139.17 119.98 68.62 48.38 mm each respective DGW, i.e., negatively correlated period. Soil electrical conductivity (EC) exponentially related DGW. For DGWs > 1.75 m, surface soil EC decreased significantly exhibited less variation Moreover, desalination rate after improved at values 2.00 m 2.25 m. Shallow resulted increased evapotranspiration intensified stress, which reduced use efficiency. To reduce resource waste stress crops, suggest 2.00~2.25 is more suitable development. These provide reference determining salinized
