The invention discloses three-flavor lactic acid bacteria for ensiling of an alpine postoral area, wherein the optimal growth temperature is 15 DEG C, and the lactic acid bacteria has the characteristics of high growth speed, large acid production amount and the like and provides favorable conditions for the blending of ensiling. The lactic acid bacteria can be rapidly fermented (shorter than or equal to 20d) at low temperature, the contents of lactic acid and total acids are increased, the pH value, the ammoniacal nitrogen/total nitrogen ratio and the contents of propionic acid and butyric acid are reduced, the fermentation quality of an ensiling feed is improved, the crude protein content of the ensiling feed and in vitro dry matter digestion rate are increased, and the lactic acid bacteria can be used as an additive in the ensiling blending process. 本发明公开了高寒牧区青贮用的3株乳酸菌，它们的最适生长温度为15℃，具有生长速度快、产酸多等特征，为青贮调制提供有利条件。能够在低温条件下快速完成发酵(≤20d)，增加乳酸和总酸含量，降低pH值、氨态氮/总氮比值、丙酸和丁酸含量，改善青贮饲料发酵品质，提高青贮饲料粗蛋白含量和体外干物质消化率，可在青贮调制过程中作为添
