Nutrient-adsorption type shii-take collagen culture medium

Abstract

The invention discloses a nutrient-adsorption type shii-take collagen culture medium. The nutrient-adsorption type shii-take collagen culture medium is prepared from, by weight, 3-5 parts of sodium carboxymethyl cellulose, 2-3 parts of sodium polyacrylate, 38-42 parts of brewer's grains, 14-16 parts of tangerine seed powder, 4-6 parts of chitosan, 2-3 parts of copper sulfate powder, 3-4 parts of potassium phosphate, 6-8 parts of zeolite powder, 38-42 parts of pigskin waste materials, 1-2 parts of sodium chloride powder, an appropriate quantity of acetic acid solution with pH 2.5 and sodium hydroxide solution and an appropriate amount of water. sodium carboxymethyl cellulose, sodium polyacrylate and other high-water absorption materials are adopted for effectively absorbing a lot of liquefied nutrients in a nutrient solution and fixing the liquefied nutrients in the culture medium, the nutrients will be not lost along with changes of environment, and it is ensured that during growth, the nutrients of shii-take are sufficiently provided.

Description

Technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a nutrient absorption type mushroom collagen cultivation substrate. Background technique [0002] Shiitake mushroom, commonly known as Chinese mushroom, is a famous edible medicinal material used to cultivate fungi. It has a long history of cultivation in my country. It is loved by consumers for its rich nutritional value and medicinal value. It has now become the second in the world. For large artificially cultivated edible fungi, due to the rapid development of the industry, the raw materials of the traditional substrate for the cultivation of mushrooms are becoming exhausted, and it is necessary to actively explore ways to replace the substrate. On the other hand, with the improvement of people's living standards, people hope that the nutritional value and medicinal value of mushrooms can also be improved, so it is necessary to provide a high-quality mushroom culti...

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
