Description

technical field

[0001] The invention relates to the technical field of functional fertilizers, in particular to a special fertilizer for multifunctional selenium-enriched slow-release rice. Background technique

[0002] Selenium is one of the 14 essential trace elements for the human body. It is known as "the fire of life", "the patron saint of the heart" and "the king of anti-cancer". Recognition ability, improve the synthesis of immune system cell antibodies, the proliferation of T cells, the level of antibodies in the blood, and double the phagocytosis and bactericidal ability of macrophages, thereby enhancing the immune function of the human body. Animal experiments have found that selenium can reduce the acute injury of aflatoxin B1, reduce the degree of hepatic central lobular necrosis and mortality. Selenium has a strong affinity with certain heavy metal elements, and combines with metals such as mercury and cadmium in the body to form metal selenoprotein complexes t...
