A kind of Polygonatum polyflora rapid seedling raising method

Abstract

The invention discloses a polygonatum cyrtonema hua fast seedling culture method. The method comprises the steps of 1, selecting plump polygonatum cyrtonema hua seeds, taking out the seeds after placing the seeds in a soak solution to be soaked for 2-3 min, and flushing the seeds with water twice; 2, spraying germination accelerating fluid on the surfaces of the polygonatum cyrtonema hua seeds, then placing the seeds in a constant temperature incubator, setting the temperature at 38-42 DEG C and the relative humidity at 80-90% in the constant temperature incubator, and taking out the seeds after 200-240 min; 3, sowing the polygonatum cyrtonema hua seeds, and then covering the surfaces of the polygonatum cyrtonema hua seeds with mixed grass. The polygonatum cyrtonema hua fast seedling culture method is simple without a high cost, and can meet the demand of large-scale seedling culture; meanwhile, the germination rate of the seeds is high, the seedling culture period is short, and the growth vigor of seedlings is good.

Description

technical field [0001] The invention belongs to the technical field of Polygonatum polyflora planting, and in particular relates to a rapid seedling raising method of Polygonatum polyflora. Background technique [0002] Polygonatum multiflora is a perennial herb of the genus Polygonatum in the family Liliaceae. The rhizomes are thick, rarely nearly cylindrical, and the stem height can reach 100 cm. The leaves are alternate, oval, ovate-lanceolate to oblong-lanceolate, Umbels, yellow-green perianth, black berries, flowering in May-June, fruiting in August-October. Polygonatum multiflora has a well-developed rhizome for storing nutrients, which is easy to watch under forests and potted plants, and its flowering period can be as long as 20 days. At present, Rhizoma Polygonatum is cultivated by rhizomes in production, and the amount of species used is large and the reproduction coefficient is low, which limits the promotion of planting in a large area, and long-term asexual rep...

AI Technical Summary

Problems solved by technology

At present, Polygonatum is cultivated by rhizomes in production, and the amount of seeds used is large and the reproduction coefficient is low, which limits the promotion of planting in a large area, and long-term asexual reproduction can easily cause the source of provenance to degenerate

However, under natural conditions, Polygonatum seeds have to go through 2 winter dormancy before they can emerge. If they are managed according to the conventional crop seed seedling raising technology, they can hardly emerge
