摘　　要：内蒙古河套灌区是全国3个特大型灌区之一,灌区每年农业用水量45亿m3左右,其中秋浇用水量占到1/3。秋浇是河套灌区特有的灌水方式,也是灌区节水保墒的关键。以河套灌区具有代表性且种植面积较大的小麦套种玉米田块为研究对象,进行秋浇覆膜灌溉新技术的试验研究,通过对不同试验方案的跟踪观测,系统地分析了这种灌溉新技术的节水增产效果。Inner Mongolia Hetao irrigation district is one of the three extra-large irrigation districts of China.Its annual irrigation water quantity is about 45 billion m3,in which the autumn irrigation quantity occupy 1/3.The autumn irrigation is the unique irrigation mode for Hetao irrigation district and the key for water-saving and moisture-maintaining.Taking the typical intercropping of wheat and corn field with larger area as study object,the experimental research on the autumn irrigation with film-mulching technology is conducted and its water-saving and production-increasing effect is analyzed through tracing observation on different experimental scheme.
