Culture method of selenium-rich black fungus

Abstract

The invention discloses a culture method of selenium-rich black fungus, and relates to the technical field of black fungus planting. According to the culture method of the selenium-rich black fungus, hexamethylphosphoramide is added into a culture medium and is combined with sodium selenite in the culture medium to generate organic selenium; sodium selenite inorganic selenium is converted into organic selenium, so that the absorption of the black fungus on the selenium element can be promoted; the goal of enriching the selenium enrichment by the black fungus is achieved; traditional Chinese medicine ingredients are also added in the culture medium; the effects of sterilization, mildew prevention, worm expelling, black fungus immunity improvement, growth promotion and yield increase are achieved; the normal growth of the black fungus is ensured; the survival rate is improved; the traditional Chinese medicine ingredients are plant sources, are easy to decompose, so that the pesticide residue cannot be caused; scientificalness and environment protection are realized; the health of eaters can be ensured.

Description

technical field [0001] The invention belongs to the technical field of black fungus planting, and in particular relates to a cultivation method of selenium-enriched black fungus. Background technique [0002] In my country, the cultivation technology of edible fungi is relatively mature. Edible fungi, especially black fungus, have high nutritional value and are loved by the common people. With the improvement of people's living standards, research on selenium-enriched foods has become more and more popular in recent years, and because of the high nutritional value of selenium-enriched foods, they are highly sought after by everyone, and their 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 solution on the fruiting bodies of black fungus, using this method can make black fungus contain selenium, but selenium exists in the form of...

Problems solved by technology

At present, there are two main methods for the cultivation of selenium-enriched black fungus to achieve selenium enrichment: one is to spray selenium solution on the fruiting bodies of black fungus, using this method can make black fungus contain selenium, but selenium exists in the form of inorganic substances It does not exist in the form of organic matter. This is because the growth cycle of black fungus is fast, and inorganic selenium is picked before it can be converted into organic selenium. This will affect the health of the eater, and it cannot be absorbed by the human body. Can not reach the original intention of selenium-enriched food; Another way is to add inorganic selenium in the culture medium, the inorganic selenium in the culture medium is converted into organic selenium through the metabolism of black fungus, but, black fungus grows fast, will cause The utilization rate of selenium in the process of selenium-enrichment cultivation is not high, and thus a better enrichment effect cannot be achieved

Moreover, during the cultivation 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
