Process of cultivating salvia miltiorrhiza by raising seedlings in greenhouse

Abstract

The invention relates to an artificial cultivation method of salvia miltiorrhiza, and aims to provide a planting method capable of greatly increasing the yield of the salvia miltiorrhiza and guaranteeing the quality of the salvia miltiorrhiza. According to the technical scheme, the method comprises the following steps: (1), raising of seedlings in a greenhouse: sowing salvia miltiorrhiza seeds and raising the seedlings in the greenhouse in November every year; (2), transplantation to a field: after 75 days of germination, transplanting the seedlings to the field and covering the seedlings with black mulching films to ensure growth of the salvia miltiorrhiza; (3), field management; providing sufficient water and fertilizers, preventing and controlling plant diseases and insect pests, and removing the black mulching films after the daytime temperature remains above 20 DEG C in May; (4), harvesting: harvesting in October or November. The method promotes salvia miltiorrhiza growth with greenhouse seedling raising in winter, the seedlings are transplanted to the field in the end of February and at the beginning of March, and by the black mulching films, the ground temperature is ensured. Compared to the method of sowing seeds in spring, the method prolongs the effective growth cycle of the salvia miltiorrhiza by about half a year, and increases annual yield of the salvia miltiorrhiza by 110% or above, and moreover, the quality of the salvia miltiorrhiza is excellent.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine plant cultivation, in particular to an artificial cultivation method of salvia miltiorrhiza. Background technique [0002] The raw material Salvia miltiorrhiza is the dry root and rhizome of Salvia mihiorrhiza Bunge, a plant of the Labiatae family, which is used to treat coronary heart disease, cerebrovascular disease and induce apoptosis of various cancer cells. Chinese medicine believes that Salvia miltiorrhiza has the effects of promoting blood circulation and removing blood stasis, dredging the menstrual flow and relieving pain, clearing the heart and eliminating troubles, cooling blood and eliminating carbuncle. For chest pain and heart pain, epigastric and hypochondriac pain, accumulation of lump in the abdomen, arthralgia due to heat pain, vexation and insomnia, irregular menstruation, dysmenorrhea, swelling and pain of sore. With the continuous research and development of new D...

Problems solved by technology

However, under natural conditions, the seeds of Salvia miltiorrhiza are not resistant to storage, and the germination rate is low. When the seeds of Salvia miltiorrhiza 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

Moreover, in the prior art, the seeds are generally sown in spring, and the growth period of the year is insufficient, and the output of the year is very low; even because the growth cycle is short and the development is not perfect, it cannot meet the medicinal requirements.

Therefore, how to take advantage of the advantages of seed propagation while solving the problem of low yield is a technical difficulty in artificial planting of Salvia miltiorrhiza
