The invention discloses a method for cultivating rhizoma polygonati seedlings. The method for cultivating the rhizoma polygonati seedlings includes the step (1) of seed collection and storage; the step (2) of seed germination, and the step (3) seedling cultivation. The method for cultivating the seedlings is high in seed germination rate and seedling rate, effectively shortens the entire seedlingculture period, reduces cost, has high benefit, and is convenient for expansion and promotion. Rhizoma polygonati seeds are mixed with sand for storage, and water absorption obstacles of the rhizoma polygonati seeds are alleviated, thereby effectively breaking the dormancy. Further, during outdoor storage, first an isolation layer is arranged, so that certain wettability can be maintained while the accumulation of water in the storage position is effectively prevented, and the dormancy breaking efficiency is greatly improved. An arranged mixed plant layer does not rot easily after being driedand rubbed. Under the immersion of rainwater and the like, on the one hand, plant-derived materials released can repel pests in the soil, and on the other hand, the plant-derived materials released can avoid seed mildew to a certain extent.
