Abstract

The invention discloses a seedling culturing method for polygonatum cyrtonema seeds. The method comprises the steps of using a sodium hydroxide aqueous solution for immersing the polygonatum cyrtonema seeds, then placing the polygonatum cyrtonema seeds in fine sand for being subjected to sand storage, wherein the fine sand is mixed and moistened with mixed liquor of ABT rooting powder, indolebutyric acid and a carbendazim aqueous solution, sowing and scattering the seeds and the fine sand obtained after sand storage together onto matrix soil in a vinyl house, wherein the matrix soil is formed by mixing wood chips, decoction dregs and pine bark, watering the seeds in the morning and in the evening everyday, and after a leaf grows out of each polygonatum cyrtonema seed, conducting periodic topdressing, weeding and pest and disease damage elimination. The method is simple, easy to do and low in cost, through the specific sand storage mode and the matrix soil seedling culturing mode, it only takes five to seven months for each polygonatum cyrtonema seed from sand storage to the state of growing out a leaf, the germination rate can reach over 80%, the germination rate of the polygonatum cyrtonema seeds is raised, germination time of the polygonatum cyrtonema seed is shortened, a large number of polygonatum cyrtonema seedlings can be obtained within a short time, requirements of planting polygonatum cyrtonema in a large area and on a large scale are satisfied, and double significance on production and economy is achieved.

Description

technical field [0001] The invention belongs to the technical field of artificial planting of medicinal plants, and in particular relates to a seedling breeding method of the endangered medicinal and edible plant Polygonatum polyflora. Background technique [0002] Polygonatum cyrtonema (Polygonatumcyrtonema) belongs to the genus Polygonatum cyrtonema of Liliaceae, and it is mainly distributed in Hebei, Shanxi, Shaanxi, Inner Mongolia and other places in my country. Under normal conditions, its wild resources are mainly distributed in forests, shrubs or hillside shade, at an altitude of 800-2800 meters. [0003] In "Flora of China", there are 31 species of Polygonatum genus recorded in my country, with a wide geographical distribution, but only Polygonatum multiflora, Polygonatum polyflora and Polygonatum yunnanensis are included in the 2015 Pharmacopoeia. Polygonatum multiflora is used as a rhizome and mainly contains niacin, quinones, starch and polysaccharides. Polygona...
