AI Technical Summary

Problems solved by technology

By adjusting the ratio of nitrogen, phosphorus and potassium fertilization, harvesting time, etc., the content of Schaftoside and Isschaftoside in Desmodium spp. Due to factors such as environment and planting techniques, the content of schiaftosides and isoschafutasides fluctuates greatly. In addition, the natural planting cycle of Desmodium sativa is also very long, usually one crop or two crops a year

Embodiment 1

[0042] Embodiment 1 A kind of planting method of Fructus chinensis for improving the content of schafposide and isoschafposide

[0043] A method for planting Prunus chinensis for improving the content of schaffatin and isoschaffatin in the present embodiment comprises the following steps:

[0044] (1), planting seedlings

[0045]Take 500 Radix chinensis seeds, put them in a 50ml centrifuge tube, add 10ml of concentrated sulfuric acid, soak for 15 minutes, suck out the concentrated sulfuric acid, and quickly rinse with pure water for 5 to 6 times until no concentrated sulfuric acid remains. Add 30ml of pure water, incubate with shaking at 28°C and 200rpm for 2 hours, rinse again with pure water for 3 to 5 times, and then shake at 28°C and 200rpm overnight, and spread the seeds in a glass dish with moist filter paper at 23-25°C. After culturing for 2 days, the newly sprouted P. chinensis seedlings were obtained.

Abstract

The invention discloses a desmodium styracifolium planting method capable of increasing schaftoside and isoschaftoside contents, which comprises the following steps: placing desmodium styracifolium seedlings planted in nutrient soil under an illumination condition of 22000 lux to 28000 lux, and culturing for not less than 7 days. After the light treatment intensity of the desmodium styracifolium seed seedlings is improved and the time length of the light treatment is precisely regulated and controlled, the content of schaftoside and isoschaftoside in the upper part of the desmodium styracifolium can be remarkably improved, and the method is simple to operate, can be used as an effective means for practically guaranteeing the clinical treatment effect of the desmodium styracifolium medicinal material, and is worthy of popularization and application. The method is applied to production of schaftoside and isoschaftoside of desmodium styracifolium.

Description

technical field [0001] The invention belongs to the technical field of plant planting, and more particularly, the present invention relates to a method for planting Prunus chinensis for increasing the content of schaffatin and isoschaffatin. Background technique [0002] As a traditional Lingnan medicinal material, Guangjincao, also known as Qiancao, Tongqiancao, etc., is a perennial herb of the genus Leguminosae. An erect subshrub in the genus Mung bean in Keshan", and with the textual research, "Modern Miao Yongqi said that the money grass (the Guangjin grass is called the money grass in the Guangdong and Guangxi regions) is very effective in the treatment of bladder stones". Only in the 1977 edition of "Chinese Pharmacopoeia" was the dried aerial part officially collected and named as Radix Glycyrrhizae, and Schafposide was used as an indicator component for the quality inspection of Radix Glycyrrhizae, and it was stipulated that its content should not be less than 0.13% ...
