Abstract: The effects of different irrigation amounts on the yield and water use efficiency of Northeast spring maize were studied in order to provide technical support for the improvement of water use efficiency of Northeast spring maize in the eastern foot of the Greater Khingan Mountains.In this experiment,5 irrigation treatments were set up.Natural precipitation and irrigation amounts as well as other indicators were monitored and recorded.The soil moisture content and soil bulk density of different treatments were measured,and related calculation was carried out combined with yield to obtain the water use efficiency of maize,and in the meantime,agronomic characteristics were determined and related analysis was carried out.The results showed that when the irrigation volume was 1 500 m3/hm2,the yield was 14.55 t/hm2 and the water use efficiency was up to 6.7 kg/m3 .When the irrigation volume of cornfield in the eastern foot of Greater Khingan Mountains is 1 500 m3/hm2,it is beneficial to improve the yield and water use efficiency of spring maize.

Key words: Northeast spring maize, Irrigation water, Yield, Water use efficiency
