摘　　要：利用 3年田间试验得到的实测资料 ,初步总结出宁夏扬黄灌区春小麦蒸散规律 ,并利用回归分析方法分别求出了潜在蒸散量、叶面指数与实际蒸散量之间的函数关系 。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.
