Salviae miltiorrhizae artificial cultivation method

Abstract

The invention provides a salviae miltiorrhizae artificial cultivation method. According to the influences of salviae miltiorrhizae endophytic fungi on growth of host plants, namely, salviae miltiorrhizae, the fungal fermentation liquor seed soaking method is adopted, and the germinative force and germination rate of salviae miltiorrhizae seeds are remarkably higher than those of contrast; through the salviae miltiorrhizae seedling and fungus co-cultivation method, the growth of salviae miltiorrhizae seedlings is promoted; by spraying fungal fermentation liquor, the growth of salviae miltiorrhizae and the quality improvement on salviae miltiorrhizae are promoted, the growth state of artificially-cultivated salviae miltiorrhizae is remarkably improved, and the foundation is laid for artificial plantation and transplantation of salviae miltiorrhizae.

Description

technical field [0001] The invention belongs to the field of cultivation of salvia miltiorrhiza, in particular to an artificial cultivation method of salvia miltiorrhiza. Background technique [0002] Endophytic fungi refer to fungi that exist in healthy plant tissues at a certain stage in their life history and do not cause obvious symptoms or damage to the host. Studies have found that plant endophytic fungi can promote plant growth by improving the nutritional conditions of plants, which is manifested in many aspects such as increasing the total biomass of plants, improving seed germination rate, seedling survival rate and inhibiting pathogenic bacteria; they can also produce secondary metabolism It can quickly activate the host's adversity response system and enhance the host's ecological adaptability to the environment. Endophytic fungi have shown bright application prospects in biopharmaceuticals, agricultural production, industrial fermentation, etc., and have attrac...

Problems solved by technology

The demand for Salvia miltiorrhiza is gradually increasing, and wild resources cannot meet the demand. Artificial cultivation has become the fundamental way to solve the source of medicine.

The propagation methods of salvia miltiorrhiza include seed propagation, split root propagation, cutting propagation and reed head propagation, etc., because split root propagation, cutting propagation and reed head propagation can shorten the growth cycle of salvia miltiorrhiza and are commonly used by people. , the content of active ingredients is extremely unstable, viral diseases and other phenomena lead to a decline in quality and output, which seriously affects the clinical application and the development of the pharmaceutical industry

Propagation of Salvia miltiorrhiza by seeds can well solve the problems of quality and yield decline due to long-term asexual reproduction

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 time they are placed for 30 days. If the storage time exceeds half a year, the germination rate will be lower than 40%. Artificial cultivation of Salvia miltiorrhiza
