| 摘 要： | 【目的】分析添加不同水平糖蜜对棉秆微贮发酵品质及有氧稳定性的影响，为生产实践提供参考。【方法】采用单因素试验设计，共6个处理，即糖蜜添加0%(对照组)、2%、3%、4%、5%、6%,添加比例以鲜重为基础。发酵第0、7、15、30、60 d取样，分析各处理发酵品质和营养品质，测定60 d开窖后各处理有氧稳定性。【结果】发酵60 d后，添加5%、6%糖蜜处理pH为4.2、4.18,氨态氮/总氮为68.99、71.40 g/kg TN,均显著低于其它处理(P<0.05),且二者差异不显著(P>0.05);添加5%、6%糖蜜处理WSC含量为21.51、23.47 g/kg DM,乳酸含量为29.19、30.37 g/kg FM,显著高于其它处理(P<0.05),且二者差异不显著(P>0.05);添加5%糖蜜有氧稳定性显著高于其它处理(P<0.05),达80 h。【结论】添加糖蜜能有效提高发酵品质，改善发酵特性，糖蜜添加量为5%。

| Abstract: | 【Objective】 This study aims to analyze the effects of adding different levels of molasses on the fermentation quality and aerobic stability of cotton stalk micro-storage with a view to providing reference for production practice.【Methods】 The experiment was performed using a single factor experimental design with a total of 6 treatments, namely molasses added to 0% (control group), 2%, 3%, 4%, 5%, 6%, and the added ratio was based on fresh weight.When sampled at the 0 th, 7 th, 15 th, 30 th and 60 th d of fermentation, the fermentation quality and nutritional quality of each treatment were analyzed, and the aerobic stability of each treatment was determined after 60 d of opening the pit.【Results】 Research showed that after 60 days of fermentation, the pH values of 5% and 6% molasses were 4.2 and 4.18, ammonia nitrogen/total nitrogen was 68.99, 71.40 g/kg TN, which were significantly lower than other treatments (P<0.05), and the difference between the two was not significant (P>0.05); The content of WSC treated with 5% and 6% molasses was 21.51 and 23.47 g/kg DM, the lactic acid content was 29.19, 30.37 g/kg FM, significantly higher than other treatments (P<0.05), and the difference between the two was not significant (P>0.05); The aerobic stability of adding 5% molasses was significantly higher than other treatments (P<0.05), up to 80 h.【Conclusion】 Adding molasses can effectively increase fermentation quality and improve fermentation characteristics.The ecommended amount of molasses is 5%. |
