In this study, E. sibiricus L.cv.chuancao No.2 at the first sprouts stage was obtained as ensilaging materials to discuss the effect of lactobacillus (FS: FAST-SILE; laetobacillus I : LAB I ; lactobacillus Ⅱ : LAB 11 ) with adding proportion on the quality of silage. The results showed: the fermentation quality and chemical composition of silage varied with different adding proportion of lactic acid bacteria, FS with adding proportion of 0.03 g-kg-1 FM can improve chemical composition of E. sibiricns L. silage; pH, value of ammonia nitrogen/total nitrogen and acid detergent fiber of silages with LAB I treatment or LABⅡ treatment decreased significantly(P〈0.05) , and lactic acid, acetic acid and dry matter content increased significantly, so as that the fermentation quality and nutrient value of E. sibiricns L. silages were improved.
