The invention relates to the technical field of plant tissue culture, in particular to a primula tibetica tissue culture rapid propagation method and application. The method comprises the following steps: drying newly harvested primula tibetica seeds in the shade, sequentially treating the seeds with 75% alcohol and 2% sodium hypochlorite, inoculating the seeds into a seed germination culture medium for culturing, shearing terminal bud parts of plants as explants, inoculating the explants into a cluster bud induction culture medium for culturing for 21-35 days, shearing the induced cluster buds into single buds, inoculating the single buds into a subculture multiplication culture medium for culturing for 45-55 days, and carrying out subculture on the single buds to obtain primula tibetica var. Tibetica var. Tibetica var. Tibetica var. Tibetica var. Tibetica var. Tibetica var. And cutting the multiple shoots subjected to subculture multiplication into small sections with 1-2 buds, inoculating the small sections into a rooting culture medium according to polarity, and culturing for 20-30 days. According to the method disclosed by the invention, the average multiplication coefficient of primary bud induction is 4.4-4.6, the rooting rate is 83.33-93.33%, and the average number of adventitious roots is more than 10.
