[0004] CN 105393797 A discloses a production method of Bailing mushroom rich in selenium and zinc. By adding sodium selenite and zinc sulfate, the ability to enrich selenium and zinc from the strain to the whole production process is improved, so that the mycelia of Bailing mushroom During the growth process, selenium in the medium is continuously absorbed and converted into biological organic selenium and zinc, but this method is not applicable to the cultivation of other edible fungi

Abstract

The invention relates to an organic selenium edible mushroom and a preparation method thereof. The preparation method includes the following steps that a first-level mother strain is prepared, the obtained first-level mother strain is prepared into a second-level original strain, the obtained second-level original strain is prepared into a third-level culture strain, the obtained third-level culture strain is subjected to seeding, fruiting, harvesting and drying, and the organic selenium edible mushroom is obtained. A selenium-rich cotton seed shell culture material is adopted for fruiting, and each 100 kg of the selenium-rich cotton seed shell culture material is prepared from 70-100 kg of cotton seed shell or corncob powder, 1-5 kg of lime, 0.5-3 kg of gypsum, 3-10 kg of corn flour, 10-18 kg of wheat bran, 15-30 g of sodium selenite, 15-30 g of ferrous sulfate, 15-30 g of zinc sulfate and 50-160 g of carbendazim, wherein the material-water weight ratio is 1:(1.2-1.4). Raw material culture and / or semi-raw material culture are / is adopted for fruiting. The organic selenium edible mushroom prepared through the preparation method has a high fruiting rate which can reach 80% or above; besides, the mushroom is thick and good in taste; through acclimatization, the content of selenium and zinc in the organic selenium edible mushroom is increased.

Description

technical field [0001] The invention relates to the technical field of agricultural production, and mainly relates to an organic selenium edible fungus and a preparation method thereof. Background technique [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 the trace elements in the human body; Zinc is a kind of trace element, the content in the human body and the daily required intake are very small, but it is beneficial to the body's sexual development, sex Function and generation of germ cells can play a...
