Efficient and stable asexual propagation method of panax notoginseng

Abstract

The invention discloses an efficient and stable asexual propagation method of panax notoginseng. The method comprises steps as follows: selection of explants; disinfection of the explants; induction of cluster buds; proliferation of the cluster buds; rooting culture; acclimatization and transplanting. The method is characterized in that a growth substrate for transplanting is prepared from following substances in parts by weight through mixing: 80-100 parts of garden soil, 25-35 parts of bentonite, 10-20 parts of kaolin, 10-20 parts of yellow sand, 3-7 parts of brown rice, 0.8-1.2 parts of water-soluble zinc salt, 0.8-1.2 parts of water-soluble magnesium salt, 0.6-0.8 parts of water-soluble potassium salt, 0.6-1.0 part of water-soluble ammonium salt and 4-8 parts of licorice extract. According to the asexual propagation method, the survival rate is high, obtained panax notoginseng seedlings have higher content of basic total saponins, and cultivation of the panax notoginseng with high content of total saponins is facilitated. With the adoption of the method, a large quantity of panax notoginseng seedlings can be obtained, the farmers' cost for obtaining the seedlings is reduced, and market competitiveness is improved.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to an efficient and stable asexual propagation method of Panax notoginseng. Background technique [0002] Sanqi [Panax notoginseng (Burk) F.H.Chen], also known as Tianqi, is a plant of the genus Ginseng in the Araliaceae family. Notoginseng tastes sweet, slightly bitter, and warm in nature. It has various pharmacological effects and health care functions such as preventing and curing cancer, anti-aging, anti-fatigue, anti-inflammation, lowering blood pressure, and lowering blood lipids. Its main pharmacological active ingredient is saponin, which is currently not available. synthetic. Panax notoginseng has strict requirements on growing conditions. Only Wenshan Prefecture in Yunnan Province and some areas in Guangxi are suitable for growing. In addition to problems such as long growth cycle, serious pests and diseases, continuous cropping obstacles, and pesticide residu...

Its main pharmacological active ingredient is saponin, which is currently not available. synthetic

However, the source of Panax notoginseng seedlings is relatively difficult, and we can only rely on purchasing seedlings from Guangxi and Yunnan, which increases the cost of Panax notoginseng cultivation and planting, and the cost advantage is small
