Abstract

The invention relates to a selenium-rich agaricus bisporus cultivation material and a preparation method thereof. The cultivation material consists of the following raw materials in percentage by weight: 50 to 60 percent of straw, 15 to 25 percent of selenium-rich alfalfa meal, 15 to 25 percent of corncob, 1 to 2 percent of calcium carbonate, 1 to 3 percent of calcium superphosphate, 1 to 3 percent of gypsum powder and 1 to 3 percent of lime powder. According to the selenium-rich agaricus bisporus cultivation material provided by the invention, the proportion of the raw materials is reasonable; the nutrition is balanced; the C/N meets the cultivation requirement of agaricus bisporus; the biotransformation efficiency and the selenium utilization rate are high; the selenium content of the agaricus bisporus produced by utilizing the cultivation material according to the conventional cultivation method is 0.15 mg/kg to 3.0 mg/kg, and is 30 to 60 times that of the common agaricus bisporus; the agaricus bisporus is rich in nutrition, is a very good selenium supplement green health product, and is wide in development prospect.

Description

Technical field: [0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to a selenium-enriched Agaricus bisporus cultivation material and a preparation method thereof. Background technique: [0002] As an essential trace element for human body and animals, selenium has many physiological functions such as protecting heart muscle, preventing Keshan disease, Kaschin-Beck disease, liver disease and reducing the risk of various cancers. The best way to supplement selenium is to add organic selenium compounds to food and eat selenium-rich foods. The edible fungi produced by adding organic selenides that are easily absorbed by fungi to the compost and transformed by mycelium are called biotransformation selenium-enriched edible fungi, rather than fortified foods that add selenium preparations to edible fungi. Therefore, the biotransformation of selenium-enriched edible fungus is an excellent functional food for supplementing se...
