Abstract: Saline soil developed on sedimentation in the Yellow River Delta has compact structure,high bulk density,and low permeability,which leads to the difficulty of salt leaching.This study analyzes the effects of sand-incorporation rates（0%,20%,50%）on soil salt leach‐ing by indoor soil column experiment.The results show that sand-incorporation can significantly increase the speed of salt leaching,shorten the leaching time,and reduce the electrical conductivity of leaching solution under the same leaching volume.With the increase in sand-in‐corporation rate,the desalination rates of K⁺,Mg²⁺and Cl^-after leaching have no significant variation,the desalination rates of Na⁺and Ca²⁺have increased,the desalination rate of SO₄^2-has reduced,the total salt desalination rate has increased,and the better the ion composition of soil.The pH of soil has increased significantly after leaching,which leads to soil alkalization,but the higher the sand-incorporation rate,the less the increase of pH,the lower the degree of soil alkalization.Sand-incorporation can significantly reduce the SAR of soil,and the more the sand-incorporation rate,the lower the SAR of soil after salt leaching.The results will provide a theoretical basis for the improvement of saline soil in the Yellow River Delta.
