Cultivation method for selenium-enriched black fungi

Abstract

The invention relates to the technical field of black fungus planting, in particular to a cultivation method for selenium-enriched black fungi. The method comprises the steps of 1 preparing a culture medium, 2 performing inoculation, 3 performing indoor spawn running, 4 performing soil preparation and 5 performing outdoor fruiting cultivation. By reasonably preparing a culture medium, the cultural medium enables black fungi to grow rapidly, organic selenium is enriched, and meanwhile the content of protein in the black fungi is increased. Traditional Chinese medicine liquid is used for performing sterilization and disinfection, insects and ants are removed, black fungus growth is further protected, meanwhile, the phenomenon that human health is threatened by pesticide residue is avoided, and the cultivation method for selenium-enriched black fungi is environmentally friendly, economical and efficient.

[0004] In China, the cultivation technology of edible fungi is relatively mature. Edible fungi, especially black fungus, have high nutritional value and are especially loved by the common people. With the improvement of people's living standards, research on selenium-rich foods has become more and more important in recent years. Popular, and because the nutritional value of selenium-enriched food is highly sought after by everyone, the economic benefits have also greatly increased. At present, there are two main methods for the cultivation of selenium-enriched black fungus to achieve selenium enrichment: one is to spray selenium on the black fungus fruiting body Solution, using this method can make black fungus contain selenium, but selenium exists in the form of inorganic matter, not in the form of organic matter, because the growth cycle of black fungus is fast, and inorganic selenium has not yet been transformed Organic selenium will be picked, which will affect the health of the eater, and it will not be absorbed by the human body, which will not reach the original intention of selenium-rich food; and another way is to add inorganic selenium to the culture medium, through the black fungus The metabolism of the medium converts the inorganic selenium in the medium into organic selenium, but the black fungus grows fast, which will lead to low utilization of selenium in the selenium-enriched cultivation process, and then can not achieve a good enrichment effect, and, In the cultivation process of selenium-enriched black fungus, pesticides and insecticides are used to protect black fungus from pests and diseases, which will cause pesticide residues in the fungus, affect human health, and fail to meet the requirements of green food
