Problems solved by technology

[0003] However, these methods do not substantially change the physical and chemical properties of the culture medium, all need to add growth promoters in the later stage of cultivation, and there are few raw materials in the culture medium, the contained carbon-nitrogen ratio is unreasonable, lack of nutrient raw materials, and the bacteria grow Slow, low inoculation quality, unable to meet the needs of producing high-quality and high-efficiency edible fungi, and still not up to the standard of pollution-free

Embodiment 1

[0023] After uniformly mixing 75% broad-leaved tree sawdust, 21% wheat bran, 1% gypsum powder, 1% slaked lime, 0.5% potassium dihydrogen phosphate, 1% white sugar, 0.5% urea and other dry materials, the total mass of 0.9~ Add 1 times the amount of water, stir and mix evenly, so that the water content reaches 50%~55%, that is, the compost is in a semi-humid state; weigh the superabsorbent resin synthesized from plant straw containing potassium according to 0.3% of the total weight of the dry material, and make it It absorbs 240ml of water, takes about 0.5h, mixes with the semi-moist compost and stirs evenly, and finally obtains a culture medium with a water content of 69.3%, calculated on the basis that the original water content of the dry material is 5%. It was steam sterilized at 121°C for 2.5 hours to obtain a culture medium for edible fungi.

Embodiment 2

[0025] Mix 80% sawdust, 12% bran, 5% corn flour, 1% sucrose, 1% gypsum, 0.5% superphosphate, 0.5% potassium dihydrogen phosphate, etc. Add 1 times the amount of water, stir and mix evenly, so that the water content reaches 50%~55%, that is, the compost is in a semi-humid state; weigh the nitrogen-containing superabsorbent resin synthesized from plant straw according to 0.5% of the total weight of the dry material, and make it It takes about 0.5 hours to absorb 360ml of water; mix it with semi-moist compost and stir evenly, and finally obtain a medium with a water content of 73.7%, calculated on the basis that the original water content of the dry material is 5%. Steam sterilize at 115°C for 3 hours to obtain edible fungus culture medium.

Embodiment 3

[0027] After uniformly mixing 78% of sawdust, 14% of bran, 5% of corn flour, 1% of sucrose, 1% of gypsum, 0.5% of superphosphate, 0.5% of potassium dihydrogen phosphate, etc. Add 1 times the amount of water, stir and mix evenly, so that the water content reaches 50%~55%, that is, the compost is in a semi-humid state; weigh the water-absorbing resin that contains potassium and is synthesized from poultry egg film according to 0.1% of the total weight of the dry material, and make it It takes about 0.5 hours to absorb 120ml of water; mix it with semi-moist compost and stir evenly, and finally get a culture medium with a water content of 63.3%, calculated on the basis that the original water content of the dry material is 5%. It was steam sterilized at 121°C for 2.5 hours to obtain a culture medium for edible fungi.

Abstract

The invention discloses a novel edible fungus culture medium and a preparation method thereof. The novel edible fungus culture medium comprises 70-85% of main material, 15-20% of auxiliary material, 3-5% of additive material and 0.1-0.8% of absorbent resin, wherein the main material comprises sawdust, straws, corncobs, and cottonseed hull; the auxiliary material comprises bran, rice bran and maize meal; and the additive material comprises land plaster, slaked lime, calcium superphosphate, white sugar and urea. The preparation method disclosed by the invention comprises the following steps of: reasonably selecting raw materials in the ratio of nutrient ingredients according to the nutritional requirements of different kinds of edible fungi to prepare the culture medium, and adding the absorbent resin synthesized by the biological materials. The permeability and the water retaining capacity of the culture medium are greatly enhanced, and the accumulation of the various nutrient elements and the slow releasing capacity to the nutrient elements are enhanced; meanwhile, the properties of the cellulose and the protein of the absorbent resin provide the nutrition in the aspect of carbon source or nitrogen source so as to ensure the sufficient supplement of the required raw materials of the fungi; and by adopting the novel edible fungus culture medium disclosed by the invention, the output of a single bag is enhanced by 25%-35%, and the fungus output time is advanced by 4-6 days.

Description

technical field [0001] The invention relates to the technical field of edible fungi cultivation, in particular to a novel edible fungus culture medium and a preparation method thereof. Background technique [0002] In recent years, my country's edible fungus business is developing on an unprecedented scale, and the production technology has also been greatly improved. In order to improve the output and quality of edible fungi, people have tackled key problems from the perspectives of strains, culture medium nutrients, fungus growth and mushroom production management technology. , great progress has been made. Opened up the use of other agricultural and sideline products and industrial production leftovers such as corn distiller's grains (public number CN101033451A), cassava residues (public number CN101508599B), traditional Chinese medicine residues (public number CN1059068A), citrus residues (public number CN101337839A), waste cotton stalks (public number No. CN1608410A) an...
