The invention discloses a seedling raising method for Paris polyphylla var. yunnanensis seeds. The seedling raising method is performed according to the following concrete steps: 1, soil selection; step 2, greenhouse construction; step 3, soil preparation; step 4, seedbed construction; step 5, seed selection; step 6, sowing; and step 7, later-stage management. According to the invention, two stepsof sand-storage after-ripening and sowing are combined into one step, so the problems of insufficient after-ripening and mechanical damage in a traditional method are avoided; meanwhile, through a reasonable soil-layer proportion, a good growth environment is provided for after-ripening and germination of Paris polyphylla var. yunnanensis, so the seedling emergence rate of the Paris polyphylla var. yunnanensis seeds is improved.
