[Objective] The objective of this paper is to analyze the dynamic changes of soil water and salt during the farming period in order to provide the scientific guidance for soil salinization control and the implementation of water-saving irrigation project.[Methods] We designed the experiments according to the soil texture, irrigation methods, crop cultivation and other factors. We calculated and analyzed the variations in water content, moisture content, soil salinity and groundwater salt through the conventional methods. Based on 2 years observation data, we analyzed the dynamic changes of soil moisture, and salt movement.[Results] Soil moisture content increased with the increase of soil depth, and the change frequency in soil moisture content decreased with the increase of soil depth during farming period.[Conclusion] During the farming period, heavy rainfall(drop water) may reduce desalting efficiency, and the surface soil shows an obvious desalting when the groundwater are shallow. Changes in groundwater salinity are closely related to rainfall.
