The invention provides a method for planting Medicago sativa in low-lying saline-alkaline land. The problems, i.e., salt damage and flooded damage of low-lying saline-alkaline land regions are solved by means of burying concealed pipes, excavating water treatment pits so as to carry out filtering and saline matter isolation on water and excavating water collecting wells leading to underground water so as to drain, and meanwhile, a purpose-made microbial fertilizer is adopted, so that the agricultural damage to the Medicago sativa is low, and the yield is high; and by the method, large-labor-amount farm work such as ploughing is not required to be carried out every year, the annual income increases gradually, and the saline-alkaline land can be reclaimed into fertile farmland in 3 to 5 years. 本发明提供了种低洼盐碱地种植紫花苜蓿的方法，通过埋设暗管、挖水处理坑对水进行过滤和盐分隔离、挖通到地下水的集水井排水的方式解决了低洼盐碱地地区的盐害和涝害问题，同时采用特制的微生物肥料，紫花苜蓿农害少、产量高；本发明无需每年进行耕地等大劳动量的农活，每年的收益逐步增长，并在3-5年后，就可以将盐碱地改良为良田。
