Bamboo fungus culture medium and preparation method thereof

Abstract

The invention relates to the field of edible mushrooms and particularly relates to an artificially-bred bamboo fungus culture medium. The bamboo fungus culture medium comprises the following components in parts by weight: 20-25 parts of bamboo bits, preferably bamboo rhizome bits with the age of over two years, 10-20 parts of brown wood bits, 10-15 parts of bamboo leaves, 10-15 parts of bamboo forest humus soils, 2-5 parts of potatoes, 5-10 parts of bagasse, 10-15 parts of wheat straws, 2-5 parts of soybean meal, 0.3-0.5 part of glucose, 0.5-1 part of calcium superphosphate, 0.5-1 part of magnesium sulfate, 0.5-1 part of ammonium nitrate and 0.5-1 part of hydrated lime, wherein the bamboo leaves and the wheat straws are soaked and bubbled for over 30 days by use of water in a fermenting tank, properly dried in the air after being bubbled until the moisture content is 25%-35%, wherein the integral moisture content of the culture medium is 70%-80%; and the culture medium is pressed by beating and compacted, so that the porosity is smaller than 10%. The culture medium is complete in nutritional ingredient, moderate in acid and alkaline condition, and capable of meeting the growth needs of the bamboo fungus and greatly increasing the yield of the artificially-bred bamboo fungus.

Description

technical field [0001] The invention relates to the field of edible fungi, in particular to a culture medium for bamboo shoots. Background technique [0002] Dictyophora is a cryptogamous fungus parasitic on the roots of dry bamboos. Its shape is slightly resembling a net-shaped dry white snakeskin. It has a dark green cap, a snow-white cylindrical stipe, and a pink egg-shaped receptacle. At the top of the stipe, there is a fine and white mesh skirt spreading downward from the cap. The whole fungus is very beautiful, colorful, rare and precious. Dictyophora is rich in nutrition, strong in fragrance and delicious in taste. It has been listed as "grass eight" since ancient times. Jane" one. [0003] Dictyophora's own nutrients are selectively absorbed from the medium through its own growth and synthesis, and the ratio of nutrients in the medium directly affects the nutritional components of Dictyophora. The traditional artificial propagation of Dictyophora directly uses a la...

Problems solved by technology

The traditional artificial propagation of Dictyophora directly uses a large amount of retting bamboo leaves, or scatter the strains of Dictyophora on the rotten organic matter of the bamboo forest. The growth of the strains is uneven and it is not easy to pick uniformly. , affect the growth size, prolong the growth cycle and reduce the yield
