The invention provides lactobacillus plantarum suitable for being made into freeze-dried powder and relates to lactobacillus plantarum. The problem that the number of thalli is obviously reduced after a freeze-dried powder type microorganism feed additive is treated through a freeze-drying process in the prior art is solved by the lactobacillus plantarum. The LP (lactobacillus plantarum)-1522 freeze-dried powder is repeatedly frozen and thawed, the survival rate can reach 74.1%, and the effective viable count can be kept by 1.2*1011 cfu/g after the lactobacillus plantarum is stored at the temperature of 28 DEG C for 105 days.
