Efficient culture medium prepared from enoki mushroom residues and used for increasing gloeostereum insarnatum fermentation speed and preparation method of efficient culture medium

Abstract

The invention discloses an efficient culture medium prepared from enoki mushroom residues and used for increasing gloeostereum insarnatum fermentation speed. The efficient culture medium is characterized by comprising, by weight, 40-50 parts of enoki mushroom residues, 22-26 parts of turf, 6-10 parts of black tartary buckwheat powder, 8-14 parts of purple rice flour, 30-36 parts of fermented bean residues, 6-7 parts of dried eupolyphoge sinensis powder, 8-10 parts of magnetic mineral powder, 8-10 parts of active carbon, 2-3 parts of potassium selenite, 1-2 parts of zinc sulphate hepta, 1-3 parts of magnesium oxide, 12-14 parts of attapulgite powder, 2-3 parts of butanediol, 6-8 parts of chitin fibers, 5-6 parts of lactic acid and 3-4 parts of calcium humate. According to the efficient culture medium, zinc is loaded to attapulgite, organic zinc is prepared through the chitin fibers, and plant bodies can conveniently absorb and utilize the organic zinc. Besides, zinc is loaded to attapulgite, zinc ion releasing efficiency is inhibited, and absorption of the plant bodies on zinc is improved. Absorption of gloeostereum insarnatum mycelia on nutrient substances can be promoted, and growth of the gloeostereum insarnatum mycelia and fruiting bodies is accelerated.

Description

technical field [0001] The invention belongs to the field of edible fungus cultivation, and in particular relates to a high-efficiency culture medium for promoting the growth rate of elm fungus prepared by using flammulina velutipes fungus residue and a preparation method. Background technique [0002] Edible fungi, as an organic green food, have received more and more people's favor, and have become an effective way for farmers to get rich. At present, there are more than a thousand kinds of edible fungi developed in my country, and the number of edible fungi that can be cultivated artificially has reached There are more than 50 kinds, mainly concentrated in several categories such as fungus, white fungus, mushrooms, shiitake mushrooms, straw mushrooms, oyster mushrooms, and slippery mushrooms. In the cultivation process, not only must achieve the goal of being green and pollution-free, but also ensure the yield and quality of edible fungi. [0003] The nutritional function...

Problems solved by technology

Currently commonly used zinc nutrients include inorganic zinc and inorganic zinc. Inorganic zinc is rich in resources and cheap in price, but it is less absorbed by organisms and is likely to cause environmental pollution. Compared with inorganic zinc, organic zinc is less irritating and has better palatability. High stability and high bioabsorption rate
