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90 d。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。

Key words: 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 5% 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 + 5% molasses; the crude fiber(CF )level was decreased; the content of the soluble carbohydrate was increased; pH value and the appearance were also improved.
