Take the Caragana intermedia, Lespedeza hedysaroides, Hedysarum fruticosum and Artemisia ordosica as silage raw materials, through the study of lactic acid bacteria, cellulose enzyme and the PFJ different concentrations of raw mixed materials and five shrub spieces on the quality of silage. Impact of finding suitable forage plant shrubs silage additives and add appropriate concentration of silage technology. The results showed that: (1) Caragana intermedia, Lespedeza hedysaroides and Hedysarum fruticosum add cellulose silage after all the fiber content are the lowest of all treatment groups, the CF decreased 5.96%,0.94% and 1.43%; on Ceratoides arborescens silage, adding additives also no significant improvement; (2) Sugar beet pulp and two shrubs mixed silage received very good results, sensory evaluation scores for the integrated out, all deal with the acid content of 67 % or more, and do not contain butyric acid, Cellulase + LF team significantly reduce the two mixed silage fiber content of various raw materials (P <0.05), add effects than the cellulose handled properly, additive effect can be arranged as follows: cellulase + lactic acid bacteria > cellulase> lactic acid bacteria; (3) Appropriate amounts of LF, LD and SG silage additives are 0.5×1010cfu·g-1 FM in Artemisia ordosica silage, add the PFJ to improve the Artemisia ordosica effectiveness of crude protein content than other lactic acid bacteria preparation; all kinds of fiber content higher than the overall lactobacillus also add other agents of the team, PFJ and the amount of glucose were 3 ml·(100 g)-1FM and 2 g·(100 ml)-1 for Artemisia ordosica silage the most appropriate content, and its effects on concentrations of lactic acid bacteria preparation is similar, PFJ in the amount of glucose in the oil and the acid content of Artemisia ordosica silage was significantly negative correlation(r=-0.601), add PFJ silage, high glucose content can effectively butyric acid fermentation on Artemisia ordosica silage, glucose addition on the Effect of silage can be summarized as: high concentration> low concentration> Do not add.
