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.

通过对一枝黄花的化学组成、纤维形态以及制浆性能进行初步探索，结果表明：(1)加拿大一枝黄花的综纤维素含量为81.86%，硝酸乙醇纤维素含量42.63%，木素含量18.86%，由化学组成看，加拿大一枝黄花是比较适宜制浆造纸的；(2)加拿大一枝黄花纤维的长宽比为36.67，纤维平均长度为44μm，从纤维长度来看，加拿大一枝黄花的纤维较短，不适宜制浆，其纤维壁腔比0.34，和其它速生材相比较小；(3)采用4种碱法制浆方案，硫酸盐蒽醌法Ⅰ，硫酸盐蒽醌法Ⅱ、烧碱法、碱性亚钠＋蒽醌法，结果显示，加拿大一枝黄花的木素非常难脱除。

The results showed that R203、P203 fractionation of wheat straw soda-mechanical pulp accounted for more than 50% and the S2 layer of the fiber was fibrillated in some degree,it is the r.
