Through three years of field trials from 2013 to 2015 year, studied the effect on growth process yield of summer maize under wide ditch irrigation and traditional planting patterns. The results showed that the stress of water both have the effect on the reproductive process under different planting patterns,the growth period of summer maize both increased with the increase of water treatment and extended from 2013 to 2015 year, compared with conventional planting, the reproductive cycle time of summer corn extended 1 to 4d; Too low or too high water stress can inhibit the normal growth of crops, the proper water treatment (L-70) can effectively promote the grain growth, achieve the benefit of water saving and high yield. The yield and its components of summer maize increased with the increase of irrigation amount from 2013 to 2015 year, compared with conventional planting, the average yield of summer maize increased by 2.38 ~ 6.04% in the wide ridge planting from 2013 to 2015 year.This suggests that the wide ridge cultivation can effectively improve maize ear traits, promote grain filling, achieve the goal of water saving and high yield of Summer Maize.
