The invention relates to a method for improving tissue culture reproductive speed of Alpinia zerumbet, which relates to the tissue culture technology of Alpinia zerumbet, and comprises the following steps that: A. seed collection is proceeded after 7 to 8 continuous sunny days, clumped Alpinia zerumbet plants which are used as seed are dug out from the soil 2 to 3 days before the seed production, soil is removed, and the Alpinia zerumbet plants are hung upside down to be dried for 2 to 3 days at a cool well-ventilated indoor place; B. lateral buds on tubers or spouts are selected as explant materials; C. adventitious buds are inducted to produce; D. adventitious buds are bred and cultured; E. adventitious buds are rooted to culture; and F. seedlings are transplanted. The rapid formation of adventitious buds is promoted through high temperature and high-concentration hormone, so the induction efficiency is improved, and the culture time is shortened; the formation of variegated leaf solid buds can be realized by changing the culture medium formula, reducing the culture temperature and increasing the light density, whitening variation can be reduced, the rapid breeding rate and seedling formation rate can be effectively improved, the factory-oriented production progress of the tissue cultured seedling can be accelerated, and the production cost can be reduced.
