Effects of Cellulase on the Chemical Compositions Characteristics and Microbial Community of Saline-alkali Land Alfalfa Silage

Abstract

Background We aim to assess the nutritional quality of alfalfa in saline-alkali and the main fermenting microorganisms acting on alfalfa in saline-alkali soils.Results In this study, We tested the nutrient composition and microbial community of Zhongmu No. 3 (salt-tolerant) alfalfa, including the nutritional fermentation quality and microbial diversity analysis of alfalfa before and after ensiling (30 days and 60 days). Then we got closely genus that related to saline-alkali soils.The validity of the microbiological data was confirmed by alpha diversity analysis. From the Microbial network, we obtained the difference of the saline-type mantle type.Conclusions we found that the silage quality of Saline-alkali alfalfa can be ensured by anaerobic fermentation with addition. The LABs that play a major role in the saline alkaline alfalfa silage are Lactobacillus, lactococcus and enterococcus.
