The invention discloses a fast efficient propagation method of Paris polyphylla. The fast efficient propagation method of Paris polyphylla includes: selecting and treating propagating materials; inducing latent buds to germinate by stratification; and managing seedling propagation and production. The fast efficient propagation method of Paris polyphylla has the advantages that seedling growth is fast, propagation coefficient is high, and seedling quality is high. The latent buds are induced to germinate by inhibiting apical dominance without damaging completeness of rhizomes, stem cutting for seedling separation is performed according to germinating latent bud spots, and accordingly many latent buds germinate, and many separate seedlings are grown. Seedling rate is one to two times higher than that in the traditional way that segmental cutting is performed prior to inducing the latent buds to germinate. When the latent buds are induced to germinate, the rhizomes are not damaged. Therefore, seedlings from the latent buds are robust. By sterilization and seed soaking prior to seedling raising after cutting and seedling separation, strong seedlings are easy to obtain and survive easily after planted in fields.
