Embodiment 1

[0024] At the Livzon Astragalus base in Hunyuan County, Datong City, Shanxi Province, the 3-year-old Astragalus membranaceus was used as the test material. On June 1, 2013, when the average plant height of Astragalus membranaceus was 30cm, a film support was built, and it was produced by Shanghai Weikang Nonferrous Plastics Factory. The blue film covers the Astragalus until the leaves are harvested. The dry weight of Astragalus root, the content of flavonoids, saponins and polysaccharides in the root were measured. Compared with the Astragalus membranaceus in adjacent plots not covered with blue film, the dry weight of Astragalus root per unit area covered with blue film increased by 0.48%, and the root The content of flavonoids in the root increased by 13.9%, and the content of saponin in the root increased by 8.1%. The economic benefit brought by the improvement of the quality of Astragalus is 4.5 times of the cost of covering the blue film.

Embodiment 2

[0026] At the Livzon Astragalus base in Hunyuan County, Datong City, Shanxi Province, with 5-year-old Astragalus membranaceus as the test material, on May 28, 2013, when the average plant height of Astragalus membranaceus was 30cm, a film support was built, using the one produced by Shanghai Weikang Nonferrous Plastics Factory The blue film covers the Astragalus until the leaves are harvested. The dry weight of Astragalus root, the content of flavonoids, saponins and polysaccharides in the root were measured. Compared with the Astragalus membranaceus in the adjacent plots not covered with blue film, the dry weight of Astragalus root per unit area covered with blue film was reduced by 0.21%, The flavonoid content in the root increased by 16.9%, and the saponin content in the root increased by 7.1%. The economic benefit brought by the improvement of the quality of Astragalus is 5.1 times of the cost of covering the blue film.

Embodiment 3

[0028] At the Livzon Astragalus Base in Hunyuan County, Datong City, Shanxi Province, the 6-year-old Mongolian Astragalus membranaceus was used as a test material. On June 3, 2013, when the average plant height of Astragalus membranaceus was 30 cm, a film support was built, and the film support was produced by Shanghai Weikang Nonferrous Plastic Factory. The blue film covers the Astragalus until the leaves are harvested. The dry weight of Astragalus root, the content of flavonoids, saponins and polysaccharides in the root were measured. Compared with the Astragalus membranaceus in the adjacent plots not covered with blue film, the dry weight of Astragalus root per unit area covered with blue film was 0.16% lower than that without it, The flavonoid content in the root increased by 15.3%, and the saponin content in the root increased by 6.2%. The economic benefits brought by the improvement of the quality of Astragalus membranaceus are 4.8 times the cost of covering the blue fil...

Abstract

The invention discloses a cultivation method for improving the quality of astragalus. The cultivation method includes performing light quality processing on 3-6 perennial astragalus on the basis of semi-wild cultivation management for conventional artificial seed sowing assisted reproduction and growth; constructing film supports in astragalus fields when the heights of growing plants reach 30cm from the last third of May to the beginning of June in a growing period; covering the astragalus by blue films for a growing season until leaves of the astragalus fall; conventionally managing the fields until the astragalus is harvested. The wavelength of blue light of the blue films ranges from 400nm to 450nm, the wave crest of the blue light is 420nm, and the light transmittance of the blue films is 85%. The cultivation method has the advantages that the cultivation method is simple, and the investment cost is low; the accumulation of flavone in roots of the astragalus is increased by 15% after the blue films cover the astragalus and the astragalus is processed as compared with a natural light condition on the premise that the dry weights of the roots of the astragalus are not obviously changed, the accumulation of saponin in the roots of the astragalus is increased by 6.5%, accordingly, the quality of the astragalus is obviously improved, and an input-output ratio of the cultivation method reaches 4.5 times at least.

Description

Technical field [0001] The invention involves the field of astragalus cultivation technology, especially by changing the cultivation method of improving the quality of astragalus by changing the quality of the light. Background technique [0002] Astragalus, also known as Mianqi, is a perennial herb, is mainly produced in Inner Mongolia, Shanxi, Gansu, Heilongjiang and other places in my country.Astragalus is a plant and plant. Its medicinal medicine has a history of more than 2,000 years.Astragalus is warm, sweet, slightly warm, and returns to the lungs, spleen, liver, and kidney meridians.Astragalus is beneficial to qi and solid surface, sweat solidifiers, sores and muscle, diuretic swelling effects.It is used to treat qi deficiency and weakness, medium qi sinking, long diarrhea deserture, blood collapse, ducts and sweating, gangrene difficulty, long collapse, blood deficiency and yellowing, internal heat and thirst, chronic nephritis, proteinuria, diabetes, etc.Increase the qi...
