摘　　要：本试验利用甜菜与玉米秸秆进行混贮,添加LF、甜渣、LF+采禾、采禾、采禾+甜渣及无添加剂(对照)进行青贮。结果表明各添加剂都显著降低了青贮料的pH、ADF、NDF和CF含量,并提高了青贮料的CP含量,各添加剂均可改善青贮饲料的发酵品质,获得优质青贮饲料,但采禾添加剂效果最佳。The effect of different biological additives(LF、Caihe、Tianzha、LF+Caihe、Tianzha+ Caihe) on mixed silage quality of sugar beet and corn stalks was studied.When any additives was added,pH,the content of ADF,NDF and CF of silage reduced significantly,and the CP of silage increased.All kinds of additives could improve fermentation quality of silage.Among them,Caihe was the optimal additive.
