Abstract

The invention relates to a selenium-enriched oyster mushroom cultivation material and a preparation method thereof. The cultivation material is prepared from the following raw materials: 45-55% of rice straw powder, 20-30% of corncob, 15-25% of selenium-enriched lucerne meal, 0.3-0.6% of urea, 1-3% of gypsum, 2-4% of lime, and 1-2% of calcium superphosphate. The selenium-enriched oyster mushroom cultivation material disclosed by the invention is reasonable in raw material proportion, balanced in nutrition and high in selenium utilization rate; C / N satisfies the cultivation requirements of oyster mushrooms; the selenium content of oyster mushrooms produced by utilizing the cultivation material according to the conventional bag type cultivation method is 0.15-18 mg / kg; the selenium content is 5-60 times of that of common oyster mushrooms; furthermore, the oyster mushrooms produced by utilizing the cultivation material according to a conventional bag cultivation method have abundant nutrition, and are safe and reliable selenium supplement green health-care products; and thus, the selenium-enriched oyster mushroom cultivation material has wide 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 oyster mushroom cultivation material and a preparation method thereof. Background technique: [0002] Selenium (Se) is one of the 14 kinds of trace elements necessary for the human body. It plays an important role in removing superoxide ion free radicals and lipid peroxides in the body, protecting biological membranes from free radical damage, and delaying the aging of the body; however, Selenium deficiency will significantly reduce the body's immunity, and it is prone to endemic diseases such as Keshan disease and Kaschin-Beck disease, as well as cardiovascular and cerebrovascular diseases; while selenium supplementation can significantly improve cancer, cataracts, and children's malnutrition, and can prevent cardiovascular and cerebrovascular diseases. The occurrence of diseases such as arteriosclerosis, hypertension, myocardia...
