In order to promote the extension and application of water-saving irrigation technology in semi-arid area of Ningxia, in this paper, considering the lack of drip irrigation system in the promotion of maize field drip irrigation in Ningxia Yanghuang Irrigation District, the experimental study on the irrigation system of maize bare soil was carried out by using the method of field experiment and demonstration application. Based on the comprehensive analysis of irrigation quota, soil water content change, water consumption, crop yield and water production efficiency, the paper suggested that drip irrigation in maize growth period was 11-12 times, irrigation quota was 300-450 m3/hm2, and irrigation fixed volume was 4 200-4 425 m3/hm2. The results showed that the target yield of maize field drip irrigation was 15 000 kg/hm2, the water production efficiency reached 3.0 kg/m3, and the corn field drip irrigation could improve the economic benefit by 3 735 m3/hm2.Thewater saving was 1 800 m3/hm2 and accounted for more than 30%.
