Pleurotus tuber-regium medium with coffee flavor, and preparation method thereof

Abstract

The invention discloses a Pleurotus tuber-regium medium with coffee flavor. The medium comprises, by weight, 30-50 parts of flower stem, 5-8 parts of peanut stem, 20-30 parts of coffee shell, 5-10 parts of coffee grounds, 8-10 parts of fresh lactic acid coconut milk, 25-35 parts of dry cassava residues, 5-6 parts of potassium dihydrogen phosphate, 6-8 parts of zinc phosphate, 4-5 parts of EDTA chelated iron, 0.4-0.6 parts of Azorhizobium, 4-6 parts of phosphogypsum, 3-4 parts of an active calcium ion liquid, 20-30 parts of wheat bran, 2-3 parts of chitin fibers, a proper amount of deionized water and a proper amount of water. Biomass charcoal is prepared and can be conveniently absorbed by Pleurotus tuber-regium; and an organic zinc compound with coffee flavor is prepared through combining the special structure of the biomass charcoal, the active calcium ion liquid and the chitin fibers, so conversion of inorganic zinc to organic zinc is promoted, in vivo enzyme synthesis of Pleurotus tuber-regium is promoted, absorption and utilization of nutrients by Pleurotus tuber-regium are promoted, and efficient cultivation of Pleurotus tuber-regium is realized.

Description

Technical field [0001] The invention belongs to the field of edible fungus cultivation, and specifically relates to a tiger milk mushroom culture medium with coffee flavor and a preparation method. Background technique [0002] As a kind of organic green food, edible fungus has been favored by more and more people and has become an effective way for farmers to get rich. At present, there are roughly a thousand kinds of edible fungi developed in my country, and the number of artificially cultivated edible fungi has reached There are more than 50 kinds, mainly concentrated in several categories such as fungus, white fungus, mushrooms and shiitake mushrooms, straw mushrooms, oyster mushrooms, and oyster mushrooms. In the cultivation process, not only to achieve the goal of green and pollution-free, but also to ensure the yield and quality of edible fungi. [0003] The nutritional function of zinc is related to a variety of enzymes. It is a constituent element of some dehydrogenases, c...

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
