Problems solved by technology

In order to meet the needs of people's health and medicine, artificial cultivation is the main way to solve the shortage of Polygonatum medicinal materials. However, due to the dormancy phenomenon of Polygonatum seeds, they have mainly relied on rhizomes for asexual reproduction for many years, which not only wastes commercial medicinal materials but also causes their offspring to degenerate. The seeds have not been effectively used, which is not conducive to the large-scale planting and promotion of Polygonatum

Abstract

The invention discloses a method for promoting germination of rhizoma polygonati seeds. The method comprises the following steps: collecting the seeds, disinfecting the seeds, preparing a seed soakingsolution, performing dehydrothermal treatment, and soaking the seeds. By the method, seed dormancy breaking technologies such as seed disinfection, dehydrothermal treatment, soaking in the seed soaking solution and growth regulation are comprehensively utilized, and obtained rhizoma polygonati seed seedlings have developed root systems and are good in growth vigor, high in growth speed and high in survival rate.

Description

technical field [0001] The invention relates to the technical field of seed treatment, in particular to a method for promoting the germination of Polygonatum seeds. Background technique [0002] Polygonatum sibiricum Red. is a perennial herb of the genus Polygonatum in the family Liliaceae. It is commonly known as "Chintouqi" and "Crowqi". It has medicinal, edible and ornamental values. , Shandong and other places. Polygonatum contains steroidal saponins, triterpene saponins, flavonoids, alkaloids, polysaccharides and other ingredients, which are recorded in the 2015 edition of "Chinese Pharmacopoeia". Polygonatum is used as medicine from its rhizomes, which can nourish qi and nourish yin, invigorate the spleen and moisten the lungs , the effect of nourishing the kidney, can be used to prevent and treat spleen and stomach qi deficiency, body fatigue, lack of stomach yin, dry mouth, lack of food, dry cough due to lung deficiency, coughing up blood due to labor, insufficient ...
