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.

摘要： 农田排水技术是解决土壤盐渍化的重要方式之一。近年来依赖合理的农业节水技术和管理理念对耕地进行改造，地下水位逐年降低，绿洲农业的快速发展使人们产生重灌轻排的思想。然而本质上盐分并未脱离土壤，耕地存在次生盐渍化风险，农田排水技术任重道远。实践证明，长期应用农田排水技术在盐碱地改良、提高作物产量、促进农业经济发展等方面起着积极作用。对解放以来新疆农田排水技术治理盐碱化的发展及概况进行梳理和总结，指出农田排水技术在实际发展中存在的实际问题，并提出新形势下通过排水技术治理盐碱化的措施与建议，为今后新疆滴灌盐渍区土壤治理提供参考。
