Problems solved by technology

Due to its good medicinal effect, coupled with the increasing number of Chinese patent medicines and health care products using Rhizoma Polygonatum as raw materials, along with the improvement of living standards, people’s awareness of health care is increasing day by day, resulting in a sharp decrease in the amount of wild Rhizoma Rhizoma Polygonatum. It has been rarely found, and the price has risen accordingly. Now the price of dry tablets has risen from less than 20 yuan / kg two years ago to 60 yuan / kg now, which has stimulated the enthusiasm of drug farmers to dig, and even more Seriously affect the living environment of sealwort

Abstract

The invention discloses a method for establishing a rapid polygonatum sibiricum reproduction system. The method comprises the following steps: seeding terminal buds or tubers of polygonatum sibiricum into an induction medium to induce germination, transferring small polygonatum sibiricum buds into a subculture medium and a rooting medium for continuous culture in sequence, thereby obtaining tissue culture seedlings of polygonatum sibiricum, and transplanting the tissue culture seedlings into a seedbed for seedling hardening. The tissue culture method disclosed by the invention is simple and convenient, simple in step and convenient to operate, obtained polygonatum sibiricum seedlings are strong in plant, high in growing ability and applicable to large-scale production, meanwhile the culture time is effectively shortened, and the production cost is lowered.

Description

technical field [0001] The invention relates to a method for rapid propagation of plants, in particular to a method for establishing a rapid propagation system of Polygonatum. Background technique [0002] Polygonatum kingianum (Polygonatum kingianum Coll.et Hemsl.) is the underground rhizome of Polygonatum kingianum Coll.et Hemsl., a yellow metal plant of Liliaceae. . Nature is sweet, flat. Tonify qi and nourish yin, invigorate the spleen, moisten the lungs, and benefit the kidneys. For weakness of the spleen and stomach, fatigue and fatigue, dry mouth and lack of food, dry cough due to lung deficiency, insufficient essence and blood, internal heat and thirst. The medical books of the past dynasties are highly praised, and the function of [Mongolian medicine] is the same as Polygonatum Polygonatum "Mongolian medicine". [Wa Medicine] Signa: Rhizome cures pulmonary tuberculosis, dry cough without phlegm, chronic illness, dry mouth, fatigue, diabetes, high blood pressure "...
