In this paper, chemistry composition, fiber morphology and pulping property in Solidago canadensis were analyzed and determined preliminarily. The results showed that the content of holocellulose was 81.86%, the content of cellulose was 42.63%, the content of lignin was 18.86%, it is feasible for using Solidago canadensis pulping based on it's chemical composition. The ratio of fiber length to width in Solidago canadensis was 36.67, the average length of fiber was 440 μm, and the length of fiber was too short to pulping. The ratio of wall thickness of fiber cell to lumen diameter was 0.34, and it was smaller than that of other woody fiber. In this experiment, four different methods of pulping were as follows: kraft-AQ pulping Ⅰ, kraft-AQ pulping Ⅱ, alkaline pulping, alkaline sulfite adding AQ pulping, but it was difficult for lignin removal in Solidago canadensis.
