摘　　要：利用碱抽提工艺对麦草秸秆进行了预处理,通过正交实验研究了各因素对麦草秸秆化学组分的影响次序和最佳反应条件;分析了不同用碱量对麦草秸秆碱预抽提效果的影响。最后,用纤维质量分析仪观察纤维形态,碱抽提前后麦草浆料比较,各个指标均有所改变,进一步验证了上述实验结果。The alkali pretreatment of wheat straw were performed by alkali extraction process. The optimal reaction conditions and the impact of the order were determined by the orthogonal experiment; the analysis of the effect of different temperature on wheat straw alkali pre-extraction was discussed. Finally, fiber morphology before and after alkaline extraction was observed by fiber quality analyzer. Comparing wheat straw pulp before and after exaction further, the various targets changed, which can verify the above results.
