Abstract: To explore the irrigation system under subsoiling tillage for western plains of Inner Mongolia,four irrigation times treatments were set under subsoiling which were 1 time,2 times,3 times and 4 times irrigation. The results showed that:irrigation had the effect of promoting the reducing of soil bulk density of plough layer under subsoiling and subsoiling can significantly reduce soil compaction in the range of 25 ~40 cm. The more irrigation times were, the higher soil moisture,water use efficiency and leaf water use efficiency were.With the increase of irrigation times, spring maize grain weight was increased significantly and then the yield was increased.
