Abstract

The invention provides a polygonatum kingianum seedling culturing method. The method comprises steps as follows: (1) seeds are soaked in ethanol, washed with clear water, soaked in a sodium hypochlorite solution and washed with clear water; obtained seeds are soaked in a water solution containing salicylic acid, gibberellin and naphthylacetic acid, and moisture is dried by filter paper; (2) riversand is paved at the bottom of a seedling culturing tray, a seedling culturing substrate is paved, polygonatum kingianum seeds are sowed on the seedling culturing tray, sufficient water is applied topermeate the seeds, and 1/3 or above of coats of the polygonatum kingianum seeds make contact with air after sowing; (3) the seeds are continuously treated for 2-3 days under the conditions that the illumination intensity is 300-500 Lx and the illumination time is 13-15 h/d; the seeds are continuously treated for 2-3 days under the conditions that the illumination intensity is 1,800-2,500 Lx and the illumination time is 10-12 h/d; (4) in a seedling culturing shed, the seeds are covered with a mixture of the seedling culturing substrate and the river sand; soil in the seedling culturing tray iskept moist, the shading rate for seedling culturing is controlled at 75%-85%, and foliage fertilizer is applied once after seedling emergence. The polygonatum kingianum seedling culturing method is high in emergence rate and strong seedling rate, is easy to implement and can realize large-scale seed breeding for seedling culture.

Description

technical field [0001] The invention relates to the technical field of Rhizoma Polygonatum seedling cultivation, in particular to a method for cultivating Rhizoma Polygonatum seedlings. Background technique [0002] Polygonatum yunnanensis is a herbaceous plant of the genus Polygonatum in the family Liliaceae. The rhizome is nearly cylindrical or nearly bead-shaped, and the nodules are sometimes irregularly diamond-shaped and plump. Berries red, 1-1.5 cm in diameter, with 7-12 seeds. The flowering period is March-May, and the fruiting period is September-October. According to the "Chinese Pharmacopoeia" 2015 edition, the traditional Chinese medicine Polygonatum Polygonatum is the dried rhizome of Polygonatum Polygonatum, Polygonatum Polygonatum or Polygonatum Polyflora. Polygonatum Polygonatum is one of the basic varieties of Polygonatum, its rhizome is relatively thick, and it is one of the best quality varieties of Polygonatum medicinal materials. Dian Huang Jing is mai...
