Problems solved by technology

The use of light time to adjust the flowering time of ornamental chrysanthemums has been widely used in commercial greenhouses in the past 50 to 60 years, but there are few reports on medicinal chrysanthemums
However, there is no relevant research on increasing the content of active ingredients in medicinal chrysanthemums by light quality irradiation.

Embodiment 1

[0033] (1) Choose a vigorously growing field, randomly select an area of ​​2x2 square meters as the R plot, and set up a 60W red light source over the R plot, with a wavelength adjusted to 440nm and a height of 2 meters.

[0034] (2) When the tops of most of the medicinal chrysanthemums have formed flower buds, start lighting treatment from September 23, as follows:

[0035] The lights of the R (red light) community are turned on from 00:00 to 00:30 every day. Observe and record the development of medicinal chrysanthemum flower buds in all plots every 2-3 days thereafter. With all the medicinal chrysanthemums blooming in all the treatment plots, the observation will end on November 1.

[0036] (3) At the end of the flowering period of medicinal chrysanthemums, collect the flowers of the R (red light) plot and bring them back to the laboratory for quality analysis. Do content testing.

Embodiment 2

[0038] (1) Choose a vigorously growing field, randomly select an area of ​​1x1 square meters as the R plot, and set up a 120W red light source over the R plot, with a wavelength adjusted to 550nm and a height of 2.3 meters.

[0039] (2) When the tops of most of the medicinal chrysanthemums have formed flower buds, start lighting treatment from September 23, as follows:

[0040]The lights of the R (red light) block are turned on at 00:00-01:00 every day. Observe and record the development of medicinal chrysanthemum flower buds in all plots every 2-3 days thereafter. As the medicinal chrysanthemums in all the treatment plots bloomed, the observation ended on November 7.

[0041] (3) At the end of the flowering period of medicinal chrysanthemums, collect the flowers of the R (red light) plot and bring them back to the laboratory for quality analysis. Do content testing.

Embodiment 3

[0043] (1) Choose a vigorously growing field, randomly select an area of ​​2.5x2.5 square meters as the R plot, set up a 150W red light source over the R plot, adjust the wavelength to 600nm, and set a height of 3 meters.

[0044] (2) When the tops of most of the medicinal chrysanthemums have formed flower buds, start lighting treatment from September 23, as follows:

[0045] The lights of the R (red light) community are turned on at 03:15-04:00 every day. Afterwards, observe and record the development of medicinal chrysanthemum flower buds in all plot groups every 2-3 days. With all the medicinal chrysanthemums blooming in all the treatment plots, the observation will end on November 1.

[0046] (3) At the end of the flowering period of medicinal chrysanthemums, collect the flowers of the R (red light) plot and bring them back to the laboratory for quality analysis. Do content testing.

Abstract

The invention provides a method for increasing the content of effective ingredients of medicinal chrysanthemum by virtue of light irradiation. The method comprises the following steps: (1) setting a red light source over a planting field of the medicinal chrysanthemum; and (2) starting the light source at fixed time within the growth period of the medicinal chrysanthemum to irradiate plants. The invention also provides the medicinal chrysanthemum cultivated by using the method, and compared with the medicinal chrysanthemum which is not irradiated by the light source, the medicinal chrysanthemum has the advantages that the content of chlorogenic acid serving as one of the effective ingredients is increased by 25%, the content of 3,5-O-dicaffeoyl quinic acid is increased by 18%, and the content of galuteolin is increased by 24%. By using the method provided by the invention, the content of the effective ingredients in the medicinal chrysanthemum can be greatly increased; and the method is simple and feasible, short in light irradiation time, low in energy consumption and favorable in popularization prospect and economic value.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a method for increasing the content of active ingredients in medicinal chrysanthemums by using light quality irradiation. Background technique [0002] Medicinal chrysanthemum is a perennial herbaceous plant of Chrysanthemum morifolium. It is used as medicine with flower heads. It is a large number of commonly used traditional Chinese medicines. Modern pharmacological research shows that medicinal chrysanthemum has various pharmacological effects such as antibacterial, anti-inflammatory, anti-oxidation, relaxing blood vessels, lowering blood fat, anti-tumor, etc. According to reports, some medicinal chrysanthemums are composed of luteolin and Glycosides have anti-cancer and anti-AIDS activities. Medicinal chrysanthemums are cultivated all over the country, among which the famous ones are Bo chrysanthemum in Anhui, Hangbai chrysanthemum in Zhejiang, Huai chrysanthemum in Hena...
