The purpose of this study is to explore the moisture and salt transport regularity of saline-alkali land in Xinjiang and Jiangsu reclamation areas under the drip irrigation. Through the drip irrigation experiment in the rain-proof soil tank， taking drip irrigation flow and soil texture as control factors， Xinjiang sandy loam and Dongtai silty loam are selected as typical soils， with four flow treatments （ 0.4， 0.7， 1.0 and 1.3 L/h） to study the effect of drip irrigation flow on the moisture and salt transport of saline alkali soil with different texture. The results show that ① with the increase in drip discharge， the average moisture content of the soil in each treatment first increases and then decreases； the moisture content of sandy loam reaches the maximum at 1.0 L/h flow rate and that of silty loam at 0.7 L/h flow rate； ② the closer the soil is to the emitter， the higher the salt leaching rate； the 0~25 cm soil layer is salt leaching area and the 25~35 cm soil layer is salt accumulation area.In 0~15 cm soil layer， The salt transport trends of the two soils are the same， and both decrease first and then increase with the increase in flow. The migration of total salt and Na⁺ shows that the average content of sandy loam is the lowest at a flow rate of 1.0L/h， and the leaching rate of silty loam is the highest at 0.7 L/h. The Cl^- leaching rate in silty loam soil is highest when the flow rate is 0.7L/h， but there is no obvious law between flow rate and Cl^- migration in the sandy loam soil； ③ The optimum drip irrigation flow rate is 1.0 L/h for sandy loam in Xinjiang and 0.7 L/h for silty loam in Dongtai according to the soil moisture and salt leaching conditions. The results can provide a basis for formulating a more reasonable irrigation system for drip irrigation system in Xinjiang and Jiangsu reclamation areas.
