The invention discloses a method for promoting in-vitro rapid propagation of curcuma sichuaensis. The method comprises the steps of curcuma sichuanensis rhizome germination, adventitious bud induction, cluster bud proliferation and cluster bud rooting and seedling strengthening, and the method is characterized in that the germination of curcuma sichuanensis rhizome buds is that curcuma sichuanensis rhizomes are germinated after being soaked in a yucca extract solution. It is found that the yucca extract can improve the germination rate of tubers and buds of the curcuma sichuanensis, promote proliferation of cluster buds of the curcuma sichuanensis and enlarge the propagation coefficient, and lanthanum nitrate can effectively promote rooting and seedling strengthening of the cluster buds of the curcuma sichuanensis. Reference is provided for optimization and improvement of the tissue culture and rapid propagation technology of the curcuma sichuanensis. 本发明公开了一种促进川郁金离体快速繁殖方法。它包括川郁金根茎萌芽、不定芽的诱导、丛生芽的增殖、丛生芽的生根壮苗，其特
