Culture method of selenium-rich lentinus edodes

Abstract

The invention relates to a culture method of selenium-rich lentinus edodes, which is characterized in that on the basis of culture medium sacked material formulas and culture management of currently known various lentinus edodes, only a selenium saline solution needs to be additionally added in the process of stirring materials in a culture medium, the total amount of the selenium salt dissolved in water plays decisive action on the concentration of the selenium salt of culture medium sacked materials, and the selenium content of the lentinus edodes taking the culture medium as nutrients is controlled by controlling the concentration of the selenium salt of the culture medium sacked materials, thereby ensuring that each batch of produced lentinus edodes has enriched selenium, and simultaneously enabling the selenium content of unit weight of the lentinus edodes to be stabilized in the required range.

Description

technical field

[0001] The invention relates to a method for cultivating shiitake mushrooms rich in trace element selenium. Background technique

[0002] Selenium is an essential trace element for the human body. Selenium deficiency can cause various diseases in the human body. Selenium deficiency in most areas of my country requires quantitative supplementation of selenium without delay. Because the range of safe daily intake of inorganic selenium by the human body is narrow, and the human body has a greater tolerance to organic selenium, it is the best way for the human body to safely supplement selenium by converting inorganic selenium into organic selenium and then absorbing it for the human body. Shiitake mushrooms have a strong ability to transform inorganic selenium into organic selenium during the growth process. The development of selenium-enriched shiitake mushrooms will benefit the future. However, it is regrettable that the selenium-enriched shiitake mushrooms w...

Embodiment Construction

[0005] After dissolving 2g of food-grade sodium selenite with a purity of 99% in 1500Kg of water, mix it with 820Kg of sawdust, 150Kg of bran, 10Kg of gypsum powder, and 20Kg of bean cake powder, and use it as a medium for cultivating selenium-enriched shiitake mushrooms for bagging , sterilizing, inoculating, cultivating bacteria, removing ears and harvesting to obtain selenium-enriched shiitake mushrooms with stable selenium content.
