为探讨预处理对玉米秸秆发酵效果的影响，利用酸、碱、氧化剂等8种化学试剂对秸秆进行预处理，每处理设置3个浓度，每个浓度3个重复，以粗纤维的变化确定最佳试剂及浓度；然后加入碳源、氮源，进行平菇菌、酵母菌、芽孢杆菌等混合菌发酵，通过测定粗蛋白质、粗纤维变化确定最优工艺条件。试验结果表明：（1）经过化学试剂预处理后的秸秆，粗纤维含量均显著降低（P ＜0.05），其中3%硫酸组效果最佳，较未处理组降低10.27%。（2）发酵处理后，3%硫酸、7%石灰水、15%氨水预处理组的秸秆粗纤维含量显著降低（P ＜0.05），粗蛋白质含量显著增加（P＜0.05），发酵效果显著优于未预处理组，结合生产实践，石灰水预处理方法更宜推广。

In order to investigate the effect of pretreatment on the fermentation of corn stover,eight kinds of chemi-cals were used to pretreat straw (acids,bases,oxiding agents) with 3 concentrations and 3 repilcates respectively.The opti-mal concentration of reagents was determined by the content of crude fiber (CF).Then adding carbon and nitrogen,fer-mengted by mixed bacteria (falt mushrooms,yeasts,bacillus).The optimal process conditions were measured by the change of crude protein(CP) and CF.The results showed that:(1)After pretreatment,the CF of straw was significantly decreased (P < 0.05),and the effect of 3% sulfuric acid was the best,which reduced by 10.27%. (2)After fermentation,the group which was pretreated by 3% sulfuric acid,7% lime,10% aqueous ammonia had more CP and less CF than those of non-pretreated group(P<0.05).The pretreatment method of lime was more appropriate to be promoted.
