The invention discloses a method for modifying soda alkaline earth by no-tillage rice growing and salt leaching, which relates to a method for modifying soda alkaline earth. The method disclosed by the invention solves the problem of the traditional soda alkaline earth modifying method that it takes long time for the yield of rice to reach the bottom line, the yield of rice is low, and the cost is high. The method for modifying soda alkaline earth comprises the following steps: 1. a land to be modified is irrigated by a single irrigation and drainage method, and then the land is smoothed by a combined dry-aqueous smoothing method and is soaked and leached; 2. rice seedlings are transplanted; 3. a multi-frequency irrigation and drainage method is adopted in the whole growing period of rice; and 4. the field management method is same as the normal rice field management method, and the management is completed after the rice is mature. The method for modifying soda alkaline earth by no-tillage rice growing and sa
