Method for planting radix salviae miltiorrhizae by aid of plug seedlings

Abstract

The invention relates to methods for artificially cultivating radix salviae miltiorrhizae, and aims to provide a method for planting radix salviae miltiorrhizae. The radix salviae miltiorrhizae yield can be greatly increased by the aid of the method, and the quality of the radix salviae miltiorrhizae can be guaranteed. The technical scheme includes that the method for planting the radix salviae miltiorrhizae comprises steps of 1), growing seedlings in greenhouses, to be more specific, sowing radix salviae miltiorrhizae seeds in the greenhouses in November in every year and growing the seedlings in the greenhouses; 2), transplanting the seedlings in fields, to be more specific, transplanting the seedlings in the fields after the radix salviae miltiorrhizae seedlings emerge for 75 days and guaranteeing growth of the radix salviae miltiorrhizae by the aid of black film mulching modes; 3), managing the fields, to be more specific, guaranteeing water and fertilizers, preventing and treating diseases and insect pests and detaching black films in May after the daytime temperatures stably reach 20 DEG C at least; 4), harvesting the radix salviae miltiorrhizae in October or November. The method has the advantages that the seedlings are grown in the greenhouses in winters and are transplanted in the fields in late February and early March, the soil temperatures are guaranteed by the aid of the black films, accordingly, growth of the radix salviae miltiorrhizae can be promoted, the effective growth cycles of the radix salviae miltiorrhizae can be prolonged by approximately half a year as compared with spring seed sowing methods, the harvesting yield of the radix salviae miltiorrhizae in the current year can be assuredly increased by 110% at least as compared with the spring seed sowing methods, and the radix salviae miltiorrhizae is excellent in quality.

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
