Rhizoma polygonati planting method

Abstract

The invention discloses a rhizoma polygonati planting method capable of achieving fast propagation of the rhizoma polygonati. The rhizoma polygonati planting method comprises the following steps of: reserving seeds, selecting land, land preparation and rhizoma polygonati seed seedling raising, field management and pest control; carrying out induction culture, subculture and differentiation cultureon the rhizoma polygonati seeds; and improving the induction culture medium according to the unique dormancy characteristic of the rhizoma polygonati seeds, so that the dormancy characteristic of therhizoma polygonati seeds can be broken during the induction process, the rhizoma polygonati can sprout quickly, and the germination rate can be improved, carrying out seedling hardening treatment toimprove the survival rate of the rhizoma polygonati seedlings, meanwhile, applying exogenous additive to the roots of the seedlings, so that the growth and leaf wilting of the rhizoma polygonati in drought stress can be effectively relieved, the drought resistance of the rhizoma polygonati can be obviously improved, the season limitation of explant supply is overcome, and meanwhile, the seedling raising method needs only three months, can achieve rapid propagation of the rhizoma polygonati, and is suitable for being popularized and applied in the field of biotechnology.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a method for cultivating and planting Polygonatum. Background technique [0002] Polygonatum is sweet in taste and flat in nature. Return spleen, lung, kidney channel. It has the functions of invigorating qi and nourishing yin, invigorating the spleen, moistening the lungs and benefiting the kidney. For weak spleen and stomach, physical weakness, dry mouth, lack of food, dry cough due to lung deficiency, insufficient essence and blood, internal heat and thirst. Modern research has shown that it has good effects on diabetes, hypertension, cardiovascular disease, tuberculosis, chronic hepatitis and other diseases, as well as in antibacterial, detoxification, anti-fatigue, anti-aging and other aspects. Its chemical components mainly include polygonatum polysaccharides, steroidal saponins, anthraquinones, alkaloids, cardiac glycosides, lignans, vitamins, and various amino ...

AI Technical Summary

Problems solved by technology

Because tuber propagation belongs to asexual reproduction, it is easy to carry viruses, and the variety degrades, resulting in a decrease in the yield and quality of Polygonatum, and Polygonatum seeds have physiological post-ripening and dormancy characteristics, and it is difficult for seeds to emerge. Now the technology of breeding Polygonatum seeds is immature and the seedling period is long. It takes about three years to germinate into seedlings, and the germination rate is low

With the increasing demand for sealwort in the medicinal material market, the rapid reproduction of sealwort has become an urgent problem to be solved, resulting in low output of sealwort and unable to meet market demand
