Field experiments were conducted to investigate the spatial-temporal distribution and the uniformity of soil water under alternative furrow irrigation in spring maize field in Cansu Province. Results showed that during the crop growing season, alternative drying and wetting furrows could incur crops to endure a water stress. thus the adsorptive ability of root system could be enhanced. As there was no zero flux plane between irrigated furrows and non-irrigated furrows under alternative furrow irrigation, lateral infiltration of water was obviously increased, thus decreasing the deep percolation. Compared with the conventional irrigation, although the water consumption in alternative furrow irrigation was reduced, the uniformity of soil water was not obviously affected.
