Auricularia polytricha culture medium containing juglans sigillata sawdust and preparation method thereof

Abstract

The invention belongs to the technical field of edible fungus cultivation, and discloses an auricularia polytricha cultivation medium containing juglans sigillata wood chips and a preparation method thereof, the auricularia polytricha cultivation medium containing juglans sigillata wood chips comprises, by weight, 1-77 parts of juglans sigillata wood chips, 77-1 part of hard weed tree wood chips, 20 parts of wheat bran, 1 part of lime and 1 part of gypsum. The prepared culture medium of the auricularia polytricha variety containing the juglans sigillata sawdust can improve the yield and the biological conversion rate of the auricularia polytricha and improve the content of polysaccharide, potassium, calcium, magnesium, boron, sulfur and zinc in sporocarp. According to the auricularia polytricha cultivated through the formula, the biological conversion rate reaches 110.60%, the yield is increased by 10.24%, the polysaccharide content in sporocarp is increased by 44.16%, the potassium content is increased by 11.07%, the calcium content is increased by 47.50%, the magnesium content is increased by 35.62%, the boron content is increased by 19.36%, the sulfur content is increased by 3.79%, and the zinc content is increased by 46.02%.

Description

technical field [0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to a fungus cultivation substrate containing walnut sawdust and a preparation method thereof. Background technique [0002] Auricularia polytricha (scientific name: Auricularia polytricha) belongs to the genus Auricularia fungus of the Basidiomycota Mushroom class Mushroom order Auricularia fungus. Modern medical research shows that the fruiting body of fungus is rich in fungus polysaccharide, which has high anti-tumor activity; it has the functions of nourishing yin and strengthening yang, clearing lung and qi, nourishing blood and promoting blood circulation, stopping bleeding and relieving pain, etc. It is a natural and powerful health care function. Food (medicine) bacteria. With the improvement of people's living standards and the requirements for quality of life, the consumption of edible fungi is increasing year by year, the market is huge and t...
