摘　　要：论述了作物需水量的概念及其计算模式。根据作物、土壤和气候资料 ,计算了中国北方主要旱地作物小麦、玉米、谷子、甘薯和马铃薯的作物需水量 ,并对这些作物的需水规律与作物生长关系进行分析。The concept of crop water requirements was discussed, based on which the calculation model of crop water requirements was established. Based on crop, soil and meteorological data, the water requirements of major dry crops in northern China, including wheat, maize, millet, sweet potato and potato, were calculated, and the patterns of water requirements of these crops were revealed and discussed in this paper.

关 键 词：旱地作物 作物需水量 作物需水规律 计算模式
