【摘要】 本文以2009年内蒙古河套灌区春小麦套种向日葵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套种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:分蘖—拔节>拔节—抽穗>抽穗—灌浆>苗期—分蘖,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,作物生育期内适宜的灌水量为250mm。
【Abstract】 This paper which based on the field measured data of wheat intercroping sunflower in Hetao district in the year of 2009 got the each crop growth stage actual evapotranspiration of interplanted crop separately according to the principle of water balance and the method of crop coefficient.Then the senstive index to water which based on the basic principle of crop- water was calculated according to the method of multiple linear regression equation in this paper.The results showed that the diversification law of crop sensitive index to water is tiller—jointin>jointing—heading>heading—grouting>seedling tiller.Finally the irrigation system was optimizated according to the method of real-coded genetic algorithmand the results showed that appropriate irrigation volume is 250mm during the crop growing stage.
