The invention discloses a rapid propagation method for tissue culture of Chinese cymbidium. The diameter of a rhizome of Chinese cymbidium is about 2mm and the length is about 1cm, and arginine of a certain concentration is added into a proliferation medium to promote cell division of the rhizome, so that rapid propagation is achieved; meanwhile, TDZ, sodium citrate and potassium sorbate are addedinto a differentiating culture medium in compound use to promote rapid differentiation to sprouts of the rhizome and prevent browning of the rhizome and the culture medium. The method disclosed by the invention is short in culture period, can save the culture medium cost, manual cost and water and electricity costs, is suitable for industrialized seedling production of Chinese cymbidium, and solves the problems that conventional propagation is low in efficiency, long in period and the like.
