Abstract

The invention discloses a cultivating method of medicinal plant herba taraxaci in an artificial light plant factory. The cultivating method comprises the steps that the period from ending of a seedling stage of herba taraxaci to the time when a plant has 16-20 main leaves and the fresh weight reaches 75 g or above is called a vegetative growth period, during the vegetative growth period, an LED light source adopts lamp beads with 660 nm red light and 450 nm blue light, and the number ratio of the red-light lamp beads to the blue-light lamp beads is (6-8):1; the period from ending of the vegetative growth period of herba taraxaci to the time when the content of caffeic acid reaches 0.2%, the content of flavone reaches 5% or above and the plant fresh weight reaches 90 g or above is called the quality enhancement period, during the quality enhancement period, the LED light source adopts the lamp beads with 660 nm red light and 450 nm blue light, and the number ratio of the red-light lampbeads to the blue-light lamp beads is (3-5):1. The cultivating method has the advantages of controlling the growth speed and physiological activity of herba taraxaci and increasing the content of thecaffeic acid and the content of flavone.

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...
