The invention discloses a method for increasing the emergence rate of alfalfa planting in moderate saline-alkali soil in northern arid regions, and belongs to the technical field of saline-alkali soil improvement and pasture planting. The method comprises the following steps that alfalfa seeds are sown from mid-to-late July to early August, irrigation and short-term field steeping are conducted after sowing, and meanwhile an acid saline-alkali soil conditioner is applied; according to the method, alfalfa seeds are sown from the middle and last ten days of July to the first ten days of August, the air temperature is high, the soil salt return degree is low, and alfalfa germination is better facilitated; according to the method, sowing is conducted firstly, then irrigation and field steeping are conducted, and the problem that seedling emergence of alfalfa is not facilitated due to field surface hardening can be solved; meanwhile, a large amount of irrigation for field steeping also has a salt leaching effect, and a saline-alkali soil acidity modifier is further added during irrigation, so that the alkalinity of the soil can be relieved, and alfalfa germination is promoted; by means of the method, the emergence rate of alfalfa can be remarkably increased to 75% or above.
