Abstract

The invention relates to a production method of a Pleurotus eryngii selenium-enriched zinc-enriched culture medium (material). A proper amount of sodium selenium and zinc sulfate are added into a culture medium and a culture material involved in the whole production process of Pleurotus eryngii, so as to improve the selenium and zinc enrichment capability from the strain to the whole production process, thus the Pleurotus eryngii mycelium can constantly absorb selenium and zinc in the medium and convert selenium and zinc into biological organic selenium and zinc during the growth process, therefore, the content of organic selenium and zinc in Pleurotus eryngii products is improved, and the selenium-enriched zinc-enriched Pleurotus eryngii products are produced. The production method comprises the production schemes of a selenium-enriched zinc-enriched stock culture medium, a stock culture medium, a cultivated seed culture medium, and a production culture material.

Description

1. Technical field [0001] The invention relates to a production method of Pleurotus eryngii-enriched selenium-enriched zinc medium (material), which belongs to the technical field of agricultural production. 2. Background technology [0002] Although the content of trace elements in the human body is not much, they are closely related to human survival and health, and play a vital role in human life. Excessive, insufficient, unbalanced or deficient intake of them will cause physiological abnormalities or diseases in different degrees. These micronutrients must usually be supplied directly or indirectly by the soil, but most people often do not get enough micronutrients through diet. Selenium is known by scientists as the "king of anti-cancer" among trace elements in the human body. Research in the scientific community has found that the level of blood selenium is closely related to the occurrence of cancer. A large number of survey data show that the level of selenium cont...
