The invention discloses a seed germination and rapid propagation method for cymbidium orchid, and relates to the technical field of plant tissue culture. The method comprises the steps that culturing is conducted through a seed germination culture medium and then conducted through a protocorm seedling differentiation culture medium, wherein the seed germination culture medium is a VW culture medium containing 6-benzyl adenine with the concentration of 0.5 mg/L to 1.0 mg/L, and the protocorm seedling differentiation culture medium is a KC culture medium containing banana juice with the mass fraction of 10%. According to the method, the seed germination and propagation speed of the cymbidium orchid can be significantly increased, the method is especially suitable for Zijingxiangyun cymbidium orchid and Laoranzi varieties difficult to germinate and culture, the culture time can be shortened, the culture technology is simple, conditions are created for commercialized production of the cymbidium orchid, and the orchid market demand exceeding supply is met.
