Embodiment 1

[0010] (1) Test method

[0011] This experiment was carried out at the College of Horticulture, South China Agricultural University from November to December 2018. Weigh 10g of broccoli seeds with good plumpness, uniform size and no damage, sterilize with 5% sodium hypochlorite solution for 15 minutes, and then soak the seeds in tap water for 5 hours. Cotton is arranged, and two layers of gauze are spread on the cotton, and a layer of filter paper of 35*25 is laid again, and on the seedling tray (bottom length*bottom width=35*25) sprayed with tap water. After 4 days of shading culture, they were placed under different light conditions, including white light, 1R1B, 1R2B and 2R1B. There are four treatments in total, with four replicates for each treatment. The relative humidity in the cultivation room is controlled at about 80%, the temperature is (25±2)°C, and the light is 16h·d -1 Cultured and sampled seven days after sowing.

Abstract

The invention provides a method for improving glucosinolate in broccoli sprouting vegetables. The method comprises the following steps: cultivating broccoli under the illumination of red and blue light LEDs, supplementing light for 16 hours by the red and blue light LEDs every day, keeping the illumination intensity at 50+ / - 5 mu mol.m<-2>.S<-1>, wherein the red light wavelength is 650-660 nm, andthe blue light wavelength is 450-460 nm. According to the method, the broccoli sprouting vegetables are cultivated by adopting the red and blue light combined LED lamps, the method has a remarkable promotion effect on the improvement of the content of glucosinolate, and the medicinal and health-care effects of the broccoli sprouting vegetables are enhanced.

Description

technical field [0001] The invention relates to a cultivation technology of broccoli sprouts, in particular to a method for increasing glucosinolates in broccoli sprouts, and belongs to the field of cultivation technology. Background technique [0002] Sprouts, commonly known as "sprouts", generally refer to edible sprouts, sprouts, sprout balls, young shoots or young stems and other sprout vegetables that are cultivated under certain conditions with plant seeds or other nutrients. It has a fresh, sweet and crisp taste, unique flavor, and contains a lot of substances that are beneficial to human health, such as VC, glucosinolates, flavonoids, phenols, etc., and is deeply loved by people. The functional components of broccoli sprouts are dozens of times that of mature broccoli inflorescences. Broccoli intake is strongly associated with a reduction in many diseases such as cancer, cardiovascular disease, and neurodegenerative diseases. For example, glucoraphanin, as an aliph...
