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

Embodiment 1

[0045] 1. Seedling cultivation in the greenhouse: In November every year, in the greenhouse, use the plugs to fill the seedling soil, and use the seeds of salvia miltiorrhiza to sow and raise the seedlings; two seedlings should be planted in each hole, and the seedlings for each hole should be determined according to the germination rate of the seeds. The temperature in the greenhouse is controlled at 18-28 ℃, and the temperature control mode of high day and low night is adopted, which is convenient for Danshen to adapt to the field environment in the future, and also uses daytime sunshine to save energy consumption for temperature control.

[0046] The seedling soil is made of 10 parts of sawdust, 100 parts of decomposed farmyard manure, 3 parts of plant ash, 2.5 parts of superphosphate, 10 parts of charcoal slag with a particle size less than 5mm, and 300 parts of natural loam.

Embodiment 2

[0073] 1. Greenhouse seedling cultivation:

[0074] The seedling soil is made of 15 parts of sawdust, 150 parts of decomposed farmyard manure, 2 parts of plant ash, 2 parts of superphosphate, 5 parts of charcoal slag with a particle size of less than 5mm, and 250 parts of natural loam.

[0075] 2. Site selection, site preparation and base fertilizer application:

[0076] The base fertilizer used is 150kg of urea per mu, 150kg of sawdust, 1500kg of decomposed farmyard manure, 50kg of plant ash, 20kg of superphosphate, 1kg of boric acid, 1kg of zinc sulfate, and 6kg of potassium sulfate.

[0077] Seven. Root spraying of mixed accelerator

[0078] Mixing accelerator configuration: acetylsalicylic acid 0.1g, ethanol 150ml, add 100L clean water, stir to dissolve completely, then adjust the pH value to 6.5-7 with sodium hydroxide or potassium hydroxide, stand or stir for more than 30min to obtain aqueous solution.

Embodiment 3

[0083] 1. Greenhouse seedling cultivation:

[0084] The seedling soil is made of 12 parts of sawdust, 120 parts of decomposed farmyard manure, 2 parts of plant ash, 2 parts of superphosphate, 8 parts of charcoal slag with a particle size less than 5mm, and 250 parts of natural loam.

[0085] 2. Site selection, site preparation and base fertilizer application:

[0086] The base fertilizer used is 150kg of urea per mu, 100kg of sawdust, 2000kg of decomposed farmyard manure, 50kg of plant ash, 20kg of superphosphate, 1kg of boric acid, 2kg of zinc sulfate, and 6kg of potassium sulfate.

[0087] Seven. Root spraying of mixed accelerator

[0088] Mixing accelerator configuration: Add 0.2g of acetylsalicylic acid and 100ml of ethanol into 100L of clean water, stir to dissolve completely, then adjust the pH value to 7-8 with sodium hydroxide or potassium hydroxide, and stand or stir for more than 30 minutes to obtain aqueous solution.

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...
