Abstract: Farmland drainage technology is one of the important ways to solve soil salinization. In recent years, due to the rational agricultural water-saving technology and management concepts, great achievements have been made in arable land reformation. The underground water level was dropped down year by year. The rapid development of oasis agriculture made people pay more attention to irrigation but neglect drainage. However, a large amount of unit salt has not been separated from the soil in essence, salinization risk is existing, so the task of farmland drainage has a long way to go. Practice has proved that the long-term application of farmland drainage technology had played an active role in the improvement of saline-alkali soil, raising crop yield and promoting agricultural economic development. This paper reviewed and summarized the development situation of managing saline-alkali soil by farmland drainage technology in Xinjiang since 1949; pointed out that the existing problems in the actual development of farmland drainage technology; and put forward measures and suggestions for managing saline-alkali soil by drainage technology under the new situation, so as to provide references for future drip irrigation in soil salinization regions of Xinjiang.
