Problems solved by technology

[0003] The content of selenium in shiitake mushrooms is very limited. At present, many growers will increase the content of selenium in shiitake mushrooms by adding selenium compounds to the cultivation substrate of shiitake mushrooms. Although the content of selenium in shiitake mushrooms will increase, but Its increase is very low, far from meeting people's demand for selenium
In addition, in order to increase the output of shiitake mushrooms, existing growers will add hormones to the substrate for shiitake mushroom cultivation, which will bring certain safety hazards to the consumption of shiitake mushrooms

Abstract

The invention discloses a cultivation method of selenium-enriched shiitake mushrooms, belonging to the technical field of cultivation of shiitake mushrooms. The method comprises the following steps: (1) preparation of a cultivation substrate; (2) inoculation; (3) management after inoculation. The invention provides the cultivation method of selenium-enriched shiitake mushrooms. Raw material is reasonably matched. The method is scientific and can effectively prevent infection of infectious microbes, which facilitates growth of shiitake mushrooms. The production of functional components of shiitake mushrooms is increased. Selenium elements are absorbed and converted by shiitake mushrooms, which improves quality of shiitake mushrooms. Additionally, selenium-enriched shiitake mushrooms can deliver great economic benefits and enjoy high market promotional value.

Description

technical field [0001] The invention belongs to the technical field of shiitake mushroom cultivation, and in particular relates to a cultivation method of selenium-enriched shiitake mushrooms. Background technique [0002] Selenium is a component of glutathione peroxidase present in the liver, heart, lung and blood plasma of the human body, which protects its cells from damage and is an effective antidote or antagonist of toxic substances such as mercury, arsenic and cadmium in the body. Coordinating with vitamin E, selenium deficiency may cause cancer, cataract, liver and heart disease, and affect the aging process. Empirical research analysis shows that the absorption rate of organic selenium is higher than 80%; the absorption rate of inorganic selenium is lower than 10%. Organic selenium can be stored in tissues, which is very beneficial to participate in the synthesis of biological enzymes; while inorganic selenium cannot be stored in tissues. Inorganic selenium is hig...
