The invention relates to a preparation method of bletilla tuber dressing easy to operate and belongs to the technical field of biomedicine. The preparation method comprises preparing bletilla polysaccharide solution with Bletilla striata polysaccharides, defoaming to obtain Bletilla striata polysaccharide casting solution, pouring the Bletilla striata polysaccharide casting solution into a mold, preparing bletilla tuber dressing by freezing and lyophilizing, spraying a layer of sodium hydroxide solution to the upper surface of the bletilla tuber dressing through a spray torch, removing acetylgroups of Bletilla striata polysaccharide molecules having a certain thickness in the upper portion of the bletilla tuber dressing, and drying to obtain the bletilla tuber dressing easy to operate. The spraying mode in the preparation method helps improve the controllability of acetyl removal for Bletilla striata polysaccharides, and solve the problem that it is difficult for a doctor treat a wound with bletilla tuber dre
