The invention discloses a rapid propagation method for performing tissue culture by using a taro stem tip, belonging to the technical field of biology. The method comprises the following steps of: selecting an aseptic taro stem tip as an explant; and performing a series of operating steps such as bud induction, subculture multiplication, rooting culture and the like to form a complete test-tube plantlet. The method comprises treatment methods for culture medium components at each abovementioned stage and induction culture. A seedling with two or more leaves can grow by performing primary culture on the taro stem tip for about 20 days, so that the process of primary culture is accelerated greatly; the growth coefficient is 4.3 on average after one-time secondary culture, secondary culture can be performed for five times generally to culture 1,470 (4.35) seedlings, and two batches can be cultured every year to form 2,940 tissue culture seed tuber seedlings, so that large-scale commercial production of taros is facilitated; and the method is also easy for obtaining regeneration plants with high genetic stability and low aberration rates.
