摘要
本文根据阿拉善盟地区水资源严重紧缺的现状，对玉米进行了为期３ａ的非充分灌溉试验。经方差分析确认试验成果是可靠的。对国外几种有代表性作物──水模型，进行拟合检验，确认当地条件下，玉米适合于Ｊｅｎｓｅｎ模型。由此用随机动态规划方法进行优化灌溉制度的制定，为指导我国西北极干旱地区的农业生产提供理论依据和技术方法。
Based on corm experimental data of the limited irrigaiton of three years inAlashan Region with the severe shortage of water resource,the variance analysis in thispaper showed the resuIt of the experiment is reliable,sveeral foreign models of cropre-sponse to water were simulated and tested.It was determined that corn was suitable forJensen mode in the locak region.The paper provided both theratical basis and technolog-ical methods for the agricultural production in severe aric region of North-west china.
