摘　　要：以无芒雀麦为原料,分别添加蔗糖(20 kg.t-1)、甲酸(2 kg.t-1和4 kg.t-1)、青宝二号(0.002 5 kg.t-1)、青宝二号+蔗糖(0.002 5 kg.t-1+20 kg.t-1)调制青贮。45 d后开启青贮料取样分析发酵品质、化学成分和有氧稳定性。结果表明,甲酸可改善青贮饲料的发酵品质,并提高青贮饲料的有氧稳定性;蔗糖可改善青贮饲料的发酵品质,但不能提高青贮饲料的有氧稳定性;添加青宝二号、青宝二号+蔗糖处理不仅能调制发酵品质优良的青贮饲料,而且有氧稳定性也较好;在所有处理组中青宝二号+蔗糖混和处理组的发酵品质最佳。Bromegrass （Bromus inermis Leyss. ） were ensiled with different additives, sucrose（20 kg · t^-1）, formic acid （2 kg · t^ -1 and 4 kg · t^ -1 ）, FAST-SILE （0. 002 5 kg · t^ -1 ） and FAST-SILE ＋ sucrose （0. 002 5 kg · t^ - 1 ＋ 20 kg · t^- 1 ）. All treatments were stored for 45 days, then sampling for the analysis of fermentation quality, chemical composition and aerobic stability of the bromegrass silage. The result indicated that formic acid can improve the silage fermentation quality and the aerobic stability; the sucrose can improve the silage fermentation quality, but can not improve aerobic stability. It can not only enhance the aerobic stability of silage, but also improve the silage fermenta- tion quality by adding FAST-SILE and FAST-SILE ＋ sucrose. And the treatment of FAST-SILE ＋ sucrose had better effect on improving silage fermentation quality than other treatments.
