摘　　要：以老芒麦(Elymus sibiricns)为研究对象,探讨青宝Ⅱ号、乳酸菌制剂1、乳酸菌制剂2、丙酸和甲酸钠等5种添加剂对老芒麦青贮品质和好氧稳定性的影响。结果表明,添加剂处理降低了老芒麦青贮饲料pH值和NH3-N/TN(P<0.05),增加了乳酸含量(P<0.05);不同添加剂处理对老芒麦青贮饲料的营养成分影响不同,但均能够提高老芒麦青贮饲料有氧稳定性(P<0.05)。In this study, wildrye （Elymus sibiricns） was obtained as ensiling materials to discuss the effect of five additives （FAST-SILE; lactic acid bacteria2; lactic acid bacteria 3; propinic acid; sodium formic） on the quality and aerobic stability of wildrye silages. Results showed that pH and the NH3-N/TN with additive treatment decreased significantly （P〈0.05） and the content of lactic acid increased significantly （P〈 0.05） ; the effect of different additives on the nutrients of wildrye silages varied; the aerobic stability of silages with additive treatments was significantly better than the control （P〈0.05）. It concluded that all the additives in the studies can improve the quality and aerobic stability of wildrye silage.
