The invention discloses a polygonatum cyrtonema finish processing or preprocessing method and an application of the polygonatum cyrtonema finish processing or preprocessing method to adjusting the immunostimulatory activity of polygonatum cyrtonema polysaccharides. The polygonatum cyrtonema finish processing or preprocessing method comprises the steps of cleaning polygonatum cyrtonema, performing cutting into slices of 2-5 mm, and dying the slices at the temperature of 40-60 DEG C for 6-16 h; performing steaming after drying, wherein the total steaming time is not longer than 4 hours; and after steaming, performing drying at 40-60 DEG C for 6-16 hours. According to the fresh polygonatum cyrtonema preprocessing method, the defects that the polygonatum cyrtonema polysaccharides are seriously damaged and the immunostimulatory activity of the polygonatum cyrtonema is remarkably reduced in the traditional processing process of steaming and airing for nine times are overcome. Besides, compared with fresh polygonatu
