The invention belongs to the technical field of plant cultivation and particularly relates to a method for planting halogeton glomeratus in saline-alkali land. The method mainly includes the following steps that the salt content in soil is measured; site preparation is conducted; watering is carried out; seeds are processed, wherein healthy and plump halogeton glomeratus seeds are selected and evenly mixed with fine sand with the particle size of 0.35-0.5 mm according to the volume ratio of 1:5-1:10; sowing is conducted; management and harvesting are carried out. Halogeton glomeratus seedling emergence is orderly and the survival rate is high in the soil environments different in salinity and alkalinity. Besides, soil salinity and alkalinity can be effectively reduced, the quality of saline-alkali soil is improved, the yield of halogeton glomeratus grains is high, and economic benefits and ecological benefits are good. The method is easy to operate, practical and easy to popularize, and opens up a new effective and feasible means for development and utilization of halogeton glomeratus in saline-alkali land in the northwest.
