Salvia miltiorrhiza planting method capable of improving tanshinone content

Abstract

The invention discloses a salvia miltiorrhiza planting method capable of improving tanshinone content, and belongs to the technical field of planting of salvia miltiorrhiza. The method comprises the following steps: (1) seed treatment; (2) sowing; (3) transplanting; and (4) management after transplanting. The salvia miltiorrhiza planting method capable of improving tanshinone content disclosed bythe invention improves the germination rate of seeds, shortens the germination cycle of seeds, improves the nutrient curing ability of seedlings, promotes synthesis of tanshinone, improves the medicinal use vale of salvia miltiorrhiza, and has good economic benefits and market value.

Description

technical field [0001] The invention belongs to the technical field of salvia miltiorrhiza planting, and in particular relates to a salvia miltiorrhiza planting method for increasing the content of tanshinone. Background technique [0002] Danshen, the name of traditional Chinese medicine. It is the dry root and rhizome of Salvia miltiorrhiza. Excavated in spring and autumn, removed the sediment and dried. Distributed in most parts of the country. Tanshinone is also called total tanshinone. It is a fat-soluble phenanthrenequinone compound with antibacterial effect extracted from the traditional Chinese medicine Salvia miltiorrhiza, from which more than 10 tanshinone monomers such as tanshinone I, tanshinone ⅡA, tanshinone ⅡB, cryptotanshinone, and isocryptanshinone are obtained, among which cryptotanshinone, dihydrotanshinone Ⅱ, the 5 monomers of hydroxytanshinone, methyl salvianic acid, and tanshinone ⅡB have antibacterial effects, as well as anti-inflammatory and cooli...

AI Technical Summary

Problems solved by technology

[0003] Existing methods of propagation of Salvia miltiorrhiza include seed propagation, split root propagation, cutting propagation and reed head propagation, etc., due to split root propagation, cutting propagation and reed head propagation, etc., due to split root propagation, cutting propagation and reed head propagation can shorten the growth rate of salvia miltiorrhiza. However, due to the long-term asexual reproduction, the content of active ingredients is extremely unstable, and the phenomenon of infectious viral diseases leads to the decline in quality and output of planted Salvia miltiorrhiza, which seriously affects the clinical application and the development of the pharmaceutical industry.

However, under natural conditions, the germination rate of salvia miltiorrhiza seeds is low, and they are not resistant to storage. When the salvia miltiorrhiza seeds are stored dry at room temperature, the germination rate of the seeds will drop by 10% every 30 days. If the storage time exceeds half a year, the germination rate will be lower than 40%, which seriously affects the Artificial cultivation of Salvia miltiorrhiza
