摘要
以三年的田间灌溉试验资料为基础，对正常灌溉与非充分灌溉条件下的夏玉米和冬小麦需水规律和需水量计算方法进行了分析，并根据非充分灌溉条件下的作物生理指标试验，对节水灌溉的机理进行了探讨．
Based on irrigation experiment for three years, this paper analyses the evapotranspiration patterns of maize and winter wheat under the condition of unsufficient irrigation, discusses the mechanism of water-saving irrigation and finally, presents the estimation method of the evapotranspiration.
