Black edible tree fungus cultivating medium and preparation method thereof

Abstract

The invention discloses a black edible tree fungus cultivating medium. The black edible tree fungus cultivating medium comprises the following raw materials in parts by weight: 72-86 parts of bamboo willow dust, 10-22 parts of pennisetum purpureum straw, 12-18 parts of pennisetum purpureum leaf powder, 10-18 parts of sugarcane bagasse, 1-5 parts of lime powder, 1-3 parts of gypsum, 5-10 parts of soybean meal, 6-8 parts of medical stone, 4-6 parts of diatomite and 10-16 parts of a nutritional additive; the nutritional additive is prepared from the following raw materials in percent: 20-35% of glucose, 30-45% of sucrose, 3-6% of calcium superphosphate, 0.3-0.8% of ammonium molybdate, 0.02-0.08% of yeast selenium, 1-2.5% of ammonium hydrogen phosphate, 0.5-0.8% of copper sulfate and 3-5% of ferrous sulfate. The black edible tree fungus cultivating medium is comprehensive in nutrition and meets the nutritional needs in the growth process of black edible tree fungi; the cultivated black edible tree fungi are high in yield and good in quality; the black edible tree fungus cultivating medium shortens the planting time.

Description

technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a black fungus cultivation substrate. Background technique [0002] Black fungus is a nutrient-rich edible fungus, and it is also a traditional health food and export commodity in my country. It has many aliases, because it grows on rotten wood and looks like a human ear, so it is named fungus. It has high nutritional value and certain medicinal value. Black fungus contains 8 kinds of amino acids and vitamins necessary for the human body, and is also rich in gum, which has a good moisturizing effect on the human digestive system. It is a kind of saprophytic fungus, without chlorophyll, it cannot produce food by itself, and it depends on the organic matter in other organisms as its nourishment. At the same time, it lives saprophytically, and it must grow and develop on dead organisms. The hyphae in the organism have a strong ability to decompose the cellulose an...

AI Technical Summary

Problems solved by technology

Due to the incomplete nutrition of the traditional cultivation medium, the yield of cultivated black fungus is not high, the quality is not good enough, and the cultivation time is long

And conventional planting raw material resources are getting less and less, so it is necessary to find new raw materials to replace or supplement existing raw material resources
