Abstract: We researched the condition of soil moisture distribution and root irrigation efficiency under root irrigation, compared root irrigation and drip irrigation in three different types of desert area in Minqin. The results showed that: (1) ecological forest had the best water permeability, the second was desert plants, then was jujube test area; (2) with deepening of soil depth, cation and anion concentration was not in balance, when the depth was 0- 60 cm and 60- 120 cm, the soil was alkaline and acidity; (3) comparing the soil water infiltration rate of root irrigation and drip irrigation, the root irrigation was more favorable to improve the soil moisture content; (4) root irrigation had higher efficiency than drip irrigation. To sum up, the efficiency of root irrigation was higher than that of drip irrigation, so root irrigation could be applied to Minqin arid desert area. At the same time, the study provided a new approach for water saving irrigation in desert area.
