Abstract: To understand current research progress of crop water-nitrogen coupling effect and provide a basis for further study on the mechanism of water-nitrogen coupling effect, the influence of water-nitrogen coupling effect on soil physical properties, nutrient elements’availability in soil, soil enzyme activity, photosynthetic performance, physiological metabolism, growth and development of aboveground and underground parts of plants, yield and quality are summarized in this paper. And the deficiency of current water-nitrogen coupling effect research are pointed out, including the effect of ecological environment on water and nitrogen coupling, the difference mechanism of water and nitrogen use efficiency, the physiological and molecular of water and nitrogen regulation, and the efficient management model of water and nitrogen coupling. At the same time, future research in this field is discussed.
