Problems solved by technology

At present, the cultivation technology of selenium-enriched fungus is mainly to provide selenium-enriched compost. Add elemental selenium and its compounds directly to the compost of fungus and mix evenly. Selenium is easy to lose, the utilization rate is not high, and sometimes some poisonous Selenium compounds will remain in the fungus, causing selenium poisoning

Abstract

The invention belongs to the technical field of edible fungus culture and particularly relates to a special rich-selenium culture medium for edible fungus. The special rich-selenium culture medium isprepared from, by weight, 60-70 parts of corncobs, 65-75 parts of sawdust, 10-20 parts of coal ash, 6-8 parts of clay, 16-20 parts of fishbone dust, 6-8 parts of mugwort powder, 10-20 parts of mushroom residues, 2-4 parts of nutrient solution, 1-3 parts of glycine betaine and an appropriate amount of lime powder. By step-by-step fermentation for mixing of raw materials, selenium and other nutrientsubstances in the raw materials can permeate completely to be adsorbed by an adsorbent, and accordingly nutrient loss can be reduced while the edible fungus in growth can be provided with nutrients timely. The special rich-selenium culture medium for the edible fungus is high in nutrient utilization rate and low in contamination rate; the cultured edible fungus is high in quality and not only rich in selenium but also superior to common edible fungus in content of elemental calcium and iron.

Description

technical field [0001] The invention belongs to the technical field of edible fungus cultivation, in particular to a special selenium-enriched compost for fungus. Background technique [0002] Fungus, also known as wood fungus, light fungus, tree ear, belongs to the fungus phylum, stratomycetes, and genus Auricularia, parasitizes on damp and decayed trees, and mostly grows on more than 120 kinds of broad-leaved trees such as oak, poplar, banyan, and locust tree On rotten wood. Fungus is sweet in taste and flat in nature, mainly containing protein, polysaccharide, calcium, iron, carotene, B vitamins and other nutrients. Anemia, thrombosis, coronary heart disease, etc.; can nourish the blood and keep the face, making the skin rosy and radiant; can dredge the stomach, lubricate the intestines, etc. [0003] Selenium is an important component of antioxidant enzymes such as glutathione peroxidase and selenium-P protein in animals and humans, and plays a role in balancing the re...
