Abstract：Under calcium fertilizer application,the one-dimensional vertical intermittent infiltration test of saline water was carried out,the results showed that,when infiltration capacity is equal,with the increase of the intermittent time and salinity,soil water content of the same soil layer is decreasing.Calcium fertilizer application makes sodium ion of infiltrated water not easy adsorb by the surface soil aggregate,the longer intermittent time,the lower adsorbed surface soil aggregate sodium ion concentration,and relative calcium ion concentration is increasing,but significant influence of intermittent time on salt concentration.The same soil layer,with salinity is increasing,calcium ion concentration and sodium ion concentration becomes higher.The surface soil layer 0～10 cm,sodium ion concentration of calcium fertilizer application is much less than sodium ion concentration of no calcium fertilizer application.The surface sodium ion concentration decreased is beneficial to crop growth in practicing.
