摘　　要：以2009年内蒙古河套灌区经济作物番茄的田间实测资料为基础,分别应用水量平衡原理与作物系数法得到经济作物生育各生育阶段实际腾发量;然后以作物-水模型为基本原理,采用多元线性回归方法对作物不同生育阶段水分敏感指标进行求解,其变化规律为:开花着果-结果盛期>苗期-开花着果>结果盛期-结果末期,最后应用基于实数编码的遗传算法对作物灌溉制度进行优化。结果表明:番茄生育期内共灌2次水,当总灌溉供水量为60mm时,苗期-开花期与开花着果-结果盛期平均每次可分配30mm。Based on-the-spot measured data of tomato in Hetao District in 2009, this paper got the each crop growth stage actual evapotranspiration of inter-planted crop separately according to the principle of water balance and the method of crop coefficient. Then the sensitive index of water based on the basic principle of crop- water is calculated according to the method of multiple linear regression equation in this paper. The results show that the diversification law of crop sensitive index of water undergoes such stages as flowering fruit fruit peak stage〉seedling flowering fruit stage〉fruit peak - last fruit stage. Finally the irrigation system is optimized according to the method of real-coded genetic algorithms. The results show that ： ①appropriate irrigation volume is 60 mm during the crop growing stage; ②the irrigate time is seedling flowering fruit stage and flowering fruit fruit peak stage.
