Abstract

The invention discloses high-selenium alfalfa and a cultivation method and application thereof. 1kg of the high-selenium alfalfa contains 10-2,000mg/kg of selenium, wherein the organic selenium accounts for more than or equal to 70%. The cultivation method of the high-selenium alfalfa comprises the following steps: applying fertilizer including sodium selenite to the alfalfa in alfalfa land before the alfalfa sprouts in spring, wherein 3-600g of sodium selenite is applied to each mu of alfalfa land; or applying fertilizer including sodium selenite to the alfalfa in alfalfa land in a dressing way two months before the alfalfa is cut down each time. The high-selenium alfalfa has stable selenium content and can be used as the selenium-enriched animal feed so that a safe selenium supplementing livestock and poultry product can be provided for people. The cultivation method has high operability, can realize the standardized production and ensure the stable content of selenium in the stems and leaves of the produced alfalfa.

Description

technical field [0001] The invention relates to a high-selenium alfalfa, a cultivation and production method and an application method of the high-selenium alfalfa, belonging to the technical field of agricultural fertilization and feed application. technical background [0002] Selenium is an essential trace element for animals and the human body. Selenium deficiency will seriously affect human health. Selenium can improve the immunity of animals and humans, scavenge free radicals, protect the optic nerve, heart and liver, etc., and can prevent diabetes, cardiovascular and cerebrovascular diseases, liver diseases, cataracts, arthritis, Keshan disease, Kashin-Beck disease and other major diseases. Selenium is also a powerful antioxidant, and its synergistic effect with vitamin E is known as the "golden partner" for scavenging free radicals and anti-oxidation. Selenium is known as "the fire of life" and "the king of anti-cancer". [0003] The form of selenium is often divide...
