Abstract: Fresh Medicago sativa and Elymus dahuricus in different ratios were made into silages to study the effects of lactobacillus on fermentation quality of mixed silages after 45 days. The fermentation quality of M. sativa and E. dahuricus silages were significantly (P<0.05) affected by additives. All bi-crop ratios except the 70∶30 ratio improved the fermentation quality of silages with a 30∶70 ratio the best treatment. There were interactions between the additives and bi-crop rations. For the lowest pH and ammonia-N contents and the highest V-score, the treatment with 0.025% lactobacillus was the best in all crop ratios.
