Abstract Anatomical, morphological and chemical characteristics of kaun straw were examined to assess their suitability for paper production and the properties were compared with wheat straw and rice straw. It was found that the fiber length of kaun straw is slightly shorter than that of wheat straw and longer than that of rice straw. It has wider fiber wall thickness than that of wheat straw and rice straw. It had acceptable derived values, especially slenderness ratio, which was lower than that of wheat straw and rice straw, and higher runkel ratio and lower flexibility coefficient. Chemical analysis of kaun straw revealed satisfactory levels of α-cellulose content (35.9 %) and klason lignin content (19.3 %). The ash content in kaun straw (7.32 %) showed lower value than that of wheat straw and rice straw. In optimum cooing conditions, kaun straw produced pulp yield of 30.0 % and 41.7 % with kappa number 15.1 and 22.5 in soda-AQ and formic acid pulping processes, respectively, the values of which were lower than that of wheat straw and rice straw.

kaun 秸秆（Seetaria-ltalika）的解剖、形态和化学特征

摘要 对考恩秸秆的解剖学、形态学和化学特征进行了研究，以评估其对造纸的适宜性，并将其特性与小麦秸秆和水稻秸秆进行了比较。结果表明，考恩秸秆的纤维长度比麦秸略短，比稻秸长。它的纤维壁厚比麦草和稻草的纤维壁厚。它具有可接受的推导值，特别是长细比，低于麦秆和稻草，具有较高的伦克尔比和较低的柔韧性系数。kaun 秸秆的化学分析表明，α-纤维素含量 (35.9%) 和 klason 木质素含量 (19.3%) 达到令人满意的水平。kaun 秸秆中的灰分含量（7.32%）低于麦秸和稻草的灰分含量。在最佳冷却条件下，
