中文摘要：试验采用单因子设计研究不同水平的尿素、糖蜜及糖蜜与尿素混合处理对甘蔗尾打捆青贮品质的影响。试验共分5组，其中1组为对照组，甘蔗尾经揉搓后直接青贮，2～5组为试验组分别添加0．6％尿素、1．0％的尿素、5％糖蜜和0．6％尿素＋5％糖蜜，每个处理3个重复，青贮期90d。试验结果表明，添加0．6％、1％的尿素及0．6％尿素＋5％糖蜜均能显著提高青贮饲料的粗蛋白质含量（P〈0．05），但3个组间差异不显著（P〉0．05）；单独加尿素的两组青贮料pH较对照组和其它试验组高，外观品质有所下降；添加5％的糖蜜和0．6％尿素＋5％糖蜜均能显著降低青贮料的粗纤维含量，增加可溶性糖的含量，青贮料的pH及外观品质较好；综合营养成分和外观品质，甘蔗尾用尿素与糖蜜混合处理其青贮料的品质最好。

外文摘要：A single factorial experiment was designed to study the effects of urea and molasses silage on the fermentation quality of the rubbed sheath of sugarcane. Group 1 was used as control, and the sheath of sugarcane for was ensilaged directly, the other 4 groups were added by 0.6% urea, 1.0% urea, 5% molasses and 50//00 molasses ＋ 0.6% urea in the sheath of sugarcane respectively. The ensiling period was lasted for 90 days. The results indicated that the protein level of the sheath of sugarcane, treated with 0.6% urea, 1% urea and 0.6% urea ＋ 5% molasses, were significantly increased, and there were no significant difference among 4 experimental groups. Treated with urea, the pH value of the ensiling sheath of sugarcane was higher and the appearance was also affected. In the ensiling sheath of sugarcane treated with 5% molasses and 0.6% urea ＋ 50/00 molasses, the crude fiber（CF ）level was decreased, the content of the soluble carbohydrate was increased, pH value and the appearance were also improved. Considering the content of the nutrients and the appearance quality, addition of 0.6 % urea ＋ 5 % molasses in the sheath of sugarcan may be appropriate way of ensiling.
