摘要： 利用1961—2009年气象资料和发育期资料，采用FAO推荐的Penman-Monteith公式计算春玉米生育期内逐日需水量，研究了承德春玉米需水量、水分盈亏的年内、年际变化规律，分析了气象因子对春玉米需水量的影响。结果表明：承德春玉米生育期平均需水总量、水分盈亏分别为522.5mm和69.4mm。在生育期内，春玉米逐日需水量的变化规律表现为先缓慢增加后减小|春玉米需水量与气象因子密切相关。

Abstract: Based on the meteorological data and the corn growth period data from 1961 to 2009 in Chengde of Hebei province, the daily water requirement of spring corn was calculated by using Penman-Monteith formula recommended by the FAO of the United Nation. The changes of spring corn water requirements, the budget in different growth period and its inter-annual variation were analyzed．The effect of meteorological factors on spring corn water requirement was discussed. The results show that the mean total water requirement and its water budget in Chengde are 522.5 mm and 69.4 mm respectively during the growth period of spring corn. The daily water requirement of spring corn firstly increases gradually and then decreases. The spring corn water requirement has a close relation with the meteorological factors.
