Mushroom collagen culture substrate prepared from coal slag

Abstract

The invention discloses a mushroom collagen culture substrate prepared from coal slag. The mushroom collagen culture substrate is prepared from the following raw materials in parts by weight: 46 to 48 parts of coal slag, 22 to 26 parts of furfural residue, 9 to 11 parts of pig bone meal, 4 to 6 parts of wood vinegar liquid, 1 to 2 parts of magnesium sulfate, 3 to 4 parts of borax, 2 to 3 parts of powdered rock phosphate, 43 to 46 parts of pigskin waste materials, 2 to 3 parts of sodium chloride powder, 2 to 3 parts of pepsase preparations, 1.8 to 2.0 parts of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and N-hydroxy succinimide, 0.4 to 0.6 part of 1-percent sodium chloride solutions, a proper amount of sodium hydroxide solution and a proper amount of water. The mushroom culture substrate uses the coal slag as main raw materials; a great number of nitrogen and carbon sources are realized; the built culture substrate has good physicochemical indexes such as water holding performance and ventilation performance; the yield of the cultured mushroom is high; the regularity is high; the factory operation is convenient; the large-area popularization and application can be realized in the field of mushroom culture.

Description

technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a mushroom collagen cultivation substrate prepared from cinders. Background technique [0002] Lentinus edodes, commonly known as Chinese mushroom, is a well-known edible medicinal material for cultivating fungi. It has a long history and tradition of cultivation in my country. It is deeply loved by consumers because of its rich nutritional value and medicinal value. It has become the second largest in the world. For the artificially cultivated edible fungi, due to the rapid development of the industry, the raw materials of the traditional substrate for shiitake mushroom substitute cultivation are increasingly exhausted, and it is necessary to actively explore ways to replace the substrate. On the other hand, along with the raising of people's living standard, people hope that the nutritional value and medical value of shiitake mushrooms can also be improved, so ...

Problems solved by technology

[0006] The invention patent application with the publication number 102617213A discloses a method of using compressed straw to prepare a mushroom cultivation substrate. The cultivation substrate uses 25-35% coarse wood chips, 15-25% fine wood chips, and It is prepared by mixing soaked compressed straw particles, 10-15% bran, and 1.0-1.5% gypsum. The culture substrate of the invention has a high lignin content, which is conducive to the utilization of shiitake mushroom hyphae, and agricultural production waste is used as cultivation Substrate raw materials improve the environment and save costs, but the cultivation substrate disclosed in the invention uses too single raw materials, which easily causes nutrient imbalance and requires the addition of additional nutrients. At the same time, the biocompatibility with shiitake mushrooms is not high. The improvement of the microenvironment and the expansion of mycelium have no promotion effect, and there is no significant increase in added value, which limits the large-scale application of the invented substrate
