摘　　要：利用河套灌区两个观测站22 a玉米观测资料和相应气象资料,计算玉米各发育期气温、日照等要素的多年平均值,分析了各发育期适宜和不利条件。利用气候资料与气候潜力产量建立回归模型,通过地理信息系统进行玉米适宜种植分区,将河套灌区玉米种植分成最适宜区、适宜区和基本适宜区等三个种植区域,并提出了不同种植区域的生产建议。Calculation was made of the mean value of main factors, such as temperature and sunshine, for corn growth in many years and, at the same time, analysis was also done of the favorable and unfavorable conditions in different stages by using the data of corn production from two observation posts in Hetao irrigation region for 22 years. Then a regression model was established on the basis of the data of climate and climatic potential yield, and the region was divided into three parts, namely the most suitable area, the suitable area and basically suitable area. At last suggestions were put forward for the improvement of eorn production in different areas.
