Abstract
Under specific rainfall,irrigation quantity and initial soil conditions,the variation characteristics of soil moisture and growth characteristic of maize under three different irrigation techniques,as sprinkler irrigation,drip irrigation and infiltration irrigation,were studied through experiment.The experiment results indicated that the effect of water saving and yield increase of infiltration irrigation was the best.Compared with drip irrigation and sprinkler irrigation,its yield increased by 1.3% and 6.3%,while water use efficiency increased from 2.64 kg/m~3 and 2.52 kg/m~3 to 2.68 kg/m~3,respectively.
