Abstract

The invention discloses a cultivation method of the medicinal plant dandelion in an artificial light plant factory, comprising: the period from the end of the dandelion seedling stage to the plant having 16 to 20 true leaves and a fresh weight of more than 75g is called the vegetative growth period, During the vegetative growth period, the LED light source uses lamp beads with a wavelength of 660nm red light and 450nm blue light. The period when the content reaches more than 5% and the fresh weight of the plant reaches more than 90g is called the quality enhancement period. During the quality enhancement period, the LED light source uses lamp beads with a wavelength of 660nm red light and 450nm blue light. The ratio of the number of red light beads to blue light beads is 3~5:1. The invention has the beneficial effects of controlling the growth rate and physiological activity of the dandelion and increasing the contents of caffeic acid and flavonoids in the plant.

Description

technical field [0001] The invention relates to the field of modern agricultural planting. More specifically, the present invention relates to a cultivation method of the medicinal plant dandelion in an artificial light plant factory. Background technique [0002] Dandelion (Herba taraxaci), also known as dandelion grass, milk grass, mother-in-law, yellow flower, etc., belongs to the perennial herb of Compositae. Dandelion is a traditional medicinal plant, with bitter, sweet and cold nature, enters the liver and stomach meridians, has the functions of clearing heat and detoxifying, diuretic and dispelling stagnation, and is mainly used for acute mastitis, lymphadenitis, furunculosis, acute conjunctivitis, cold Fever, acute tonsillitis, etc. Modern research reports that the main active ingredients of dandelion are flavonoids, organic acids and sterols. [0003] Artificial light plant factories can achieve high-quality, fast and safe output of plants by controlling environm...
