To provided the theory basis for the reasonable exploitation and sustainable utilization of saline-sodic soil with shallow water table, soil water potential was observed by tensiometer and, according to different growth periods of Fructus Lyeii, soil above water table was sampled in each layer to study the annual dynamic changers of soil salt. The results showed that water was kept infiltrating radially from the dripper till the next irrigation; during the rainy season, rainwater moved from the upper layer to the deeper and slowed down while water table rose up; soil water than moved from the middle of the bed to the slope. Salt movement was obviously affected by water movement and it can be divided into five stages in a year: evaporation in spring-salt accumulated stage; leaching by irrigation-salt stabilized stage; leaching by rainfall-desalinized stage; evaporation in autumn-salt accumulated stage and relatively stable stage in winter. At the experiment field, after mulch-drip irrigation for a year, salt accumulated insignificantly and EC1:5 of the bed varied from 1.64 dS ^-m to 1.69 dS ^-m. The distribution of salt in transect indicated that soil salt was regulated by mulch-drip irrigation and suitable soil environment was provided for root growth, so the saline-sodic soil with shallow water table can be utilized by mulch-drip irrigation with saline water.
