【Abstract】 In this paper the regularity of soil moisture evaportranspiration in spring wheat filed from the Yellow River pumping irrigation district in Ningxia is summarized based on a number of measured data from filed experiments and the regression formula is adopted to obtain the relationship of potential evapotranspiration and leaf exponent with the actual evapotranspiration. From this the procedure of water saving irrigation is developed for reference use.更多还原
