To investigate the effects of different additives on the silage quality and microbial population of Elymus dahuricus，Elymus dahuricus was used as the raw material and herein and set up five treatment groups： P₁ （no additive， add the same amount of distilled water）， P₂ （adding Lactobacillus plantarum，the addition amount was 1×10⁶ CFU·g^-1 FW）， P₃ （adding molasses， the addition amount was 20 g·kg^-1 FW）， P₄ （adding Lactobacillus buchneri，the addition amount was 1×10⁶ CFU·g^-1 FW）， and P₅ （adding cellulase，the addition amount was 50 U·g^-1 FW）. After 60 days of ensiling， the nutritional quality， fermentation characteristics， and microbial counts were determined. The results showed that different silage additives significantly affected the contents of water soluble carbohydrates （WSC）， neutral detergent fiber （NDF）， acid detergent fiber （ADF）， and crude ash in Elymus dahuricus silage（P<0.05）. The additives significantly decreased the pH value of the silage and significantly increased the lactic acid content （P<0.05）， while significantly reducing the propionic acid content （P<0.05）. Comprehensive membership function analysis indicated that quality of Elymus dahuricus silage was the best when the addition amount was 20g·kg^-1 FW molasses.
