The invention provides a concentrated seedling culture method for polygonatum odoratum. The concentrated seedling culture method comprises the following steps: step 1, selecting a seedling bed; step 2, manufacturing a non-woven fabric planting culture medium; step 3, selecting seeds and coating seed stems; step 4, sowing the polygonatum odoratum; step 5, carrying out field management of the polygonatum odoratum seedling bed; step 6, preventing and treating diseases and insect pests of the polygonatum odoratum; step 7, transplanting adult seedlings. With the adoption of the concentrated seedling culture method, the cost can be reduced; the resistance capability of the polygonatum odoratum of the first year is enhanced through utilizing the population effect of the polygonatum odoratum, and technical supports are providing for large-scale popularization and planting of the polygonatum odoratum.
