According to the one-time fertilization planting method for the highland barley in the riverside region, after a film-coated blended fertilizer required by the whole growth period of the highland barley is used in one time, compared with a conventional highland barley planting method, the yield and the content of beta-glucan in highland barley grains are greatly increased, on one hand, the growth period of the highland barley cannot be shortened, and on the other hand, the yield of the highland barley is increased; on the other hand, the yield and the content of beta-glucan in grains of the highland barley are higher than those of the highland barley in a conventional fertilization mode. The method solves the problems of high labor cost and low fertilizer utilization rate of the conventional planting method of the naked barley.
