Modified urea-formaldehyde resin water- and fertilizer-retention high-effective culture medium for flammulina velutipes and preparation method thereof

Abstract

The invention discloses a modified urea-formaldehyde resin water- and fertilizer-retention high-effective culture medium for flammulina velutipes, which includes the following components, by weight, black soybean skin, shell powder, yeast extract, limestone, urea-formaldehyde resin, oligo-chitosan, coffee bean residue, expanded linen fiber, modified starch solution, rhizobium, bran obtained by fermenting white liquor with brewing yeast, soybean phospholipid, citric acid, cotton seed skin, fermented soybean meal, residue of tremella fuciformis, loofah sponge, glucose, amino acids, zinc sulfate, manganese sulfate and sodium bicarbonate. By means of the yeast extract and the rhizobium supported on the loofah sponge at the same time, decomposition and utilization of the main and auxiliary materials are effectively promoted. The urea-formaldehyde resin, the oligo-chitosan, the coffee bean residue, the expanded linen fiber, the citric acid composition are loaded on the loofah sponge can effectively regulate distribution of moisture and nutrients of the culture medium well, and further achieves the effect of regulating the culture technology and growth principle of the flammulina velutipes. The culture medium is low in labor intensity of culturing the flammulina velutipes and the cultured flammulina velutipes is high in yield and delicious in taste.

Description

technical field [0001] The invention relates to the technical field of edible fungus medium, in particular to a modified urea-formaldehyde resin water- and fertilizer-retaining high-efficiency medium for Flammulina velutipes and a preparation method thereof. Background technique [0002] Straw mushroom has fresh and tender meat and rich nutrition. It is an important tropical and subtropical mushroom. Every 100g fresh mushroom contains 207.7mg vitamin C, 2.68g crude protein and 2.24g fat. Straw mushroom protein contains 18 kinds of amino acids, among which the eight essential amino acids for the human body are neat and high in content, accounting for 38.2% of the total amino acids. At the same time, straw mushroom also has the function of detoxification, such as lead, arsenic, benzene, etc. enter the human body, and can be combined with it to form anticorruption, which is excreted with urine. In addition, it can slow down the body's absorption of carbohydrates, and is a goo...
