Abstract

In shallow groundwater agricultural fields, water exchanges between groundwater and soil water happen frequently and intensively. This paper analyzes the regime of subsurface water during the growing period of winter wheat from October 1998 to June 1999 in Yucheng area. The results showed that a significant proportion of field evapotranspiration was supplied by groundwater evaporation, whereas the role of groundwater evaporation was not considered during irrigation, leading to soil water percolation into groundwater. In order to improve water use efficiency of crops, some measures were put forward in the paper
