The invention discloses a nutritional buckwheat sprout cultivation method. The nutritional buckwheat sprout cultivation method includes the following steps of 1 germination accelerating, 2 sowing, 3 management and 4 harvesting. The nutritional buckwheat sprout cultivation method is simple in process, a cultivation cycle is shortened to be 8-9 days, the germination rate is 94-96%, the resistance is strong, and buckwheat sprouts vigorously grow, and are rich in nutrition, diversified in health care function and capable of promoting metabolism, enhancing immunity, protecting cardiac-cerebral blood vessels, maintaining beauty, keeping young, protecting the mouth, relieving internal heat or fever and resisting cancers. Buckwheat seeds are subjected to microwaves, ultrasound and soaking in sprouting liquid, the sprouting liquid rapidly penetrates into the seeds, the time is saved, nutrition of the seeds and cell activity are strengthened, the germination rate of the seeds is improved, resistance is enhanced, and the germination time is shortened. After germination accelerating, non-germinated seeds are directly added to a cultivation matrix of a seedling tray, antimicrobial and insecticidal effects are achieved, and the survival rate of the seeds is improved, so that buckwheat sprouts grow upright, are rich in nutrition, have a health-care function, adsorb harmful substances and are nutritional, safe, green and healthy.
