Abstract: Plot experiment of winter wheat irrigation was carried out to analyze the effects of irrigation amounts on water use efficiency, salt-water distribution and yield of winter wheat. Results show that the soil water content depends on irrigation amount. Marginal soil water content increases first then decreases, water use efficiency decreases, and the salt content of surface soil increases first then decreases with the increase of irrigation amount. Yields of winter wheat decrease first then increase as the surface soil salt content increases from 0.07% to 0.09%. Considering water-saving, salt-limiting and high-producing, the optimum irrigation amount for Nanpi experiment station in Hebei Province was obtained.
