摘　　要：春小麦套种向日葵是河套灌区主要的粮食作物与经济作物种植模式之一。针对河套灌区目前典型种植结构以及地下水位埋深比较浅的独特情况,应用土壤水动力学理论和SPAC系统理论知识,定量分析计算作物生长季节大气水、土壤水、灌溉水、作物水和地下水的相互转换关系;同时应用FAO推荐的Penman-Monteith方法及套种模式作物系数计算方法,对作物实际腾发量进行计算;最后应用水量平衡原理对田间灌溉水有效性进行评价,为河套灌区灌溉制度改进与优化提供理论依据。Wheat intercropping sunflower is one of the main plant patterns about cereals and economic crops in the Hetao Irrigation District.For the current typical crop plant patterns and the unique situation of shallow groundwater level,by using the theory of soil water dynamics and the knowledge of SPAC systemic theory,this paper calculates and quantitatively analysises the interchangeable relations of atmospheric water,soil water,irrigation water,crop water and groundwater during growing seasons.At the same time,by using the Penman-Monteith method recommend by FAO and the method of calculating intercropping crop coefficient,it calculates the actual crop evapotranspiration.Finally this paper evaluates the field irrigation efficiency by using the principle of water balance and provides a theoretical basis for improving and optimizating irrigation schedules in this area..
