Abstract:: The purpose of this study was to make full use of the limited natural rainfall, improve water use efficiency in dry farming area and promote high and stable yield of spring corn. The experiment was designed as three strip shapes which were 60 cm∶60 cm, 60 cm∶45 cm and 60 cm∶30 cm, respectively, to study the impacts of different strip shapes on spring corn yield and soil water while conventional farming was set as CK during the period from 2008 to 2009. The results showed that soil water storage of different strip shapes increased compared separately to CK during growth period of corn. The output differences of spring cron were obvious because of the differences of rainfall and rainfall distribution during the period from 2008 to 2009. But the trend of increasing production of different stripshapes was same and the yield of different strip shapes increased by 9.85%～14.52% and 24.88%～27.20%, respectively, and water use efficiency increased by 12.57%～14.75% and 7.42%～18.03%, respectively, compared to CK through two years field experiments. By regression analysis, the optimum ratio of furrow to ridge for spring corn was about 60 cm∶40.5 cm, which made the theory corn production highest. This technology could improve water use efficiency and yield compared to CK in the semi-arid areas.
