Abstract

The invention discloses a mushroom culture medium prepared from coffee grounds. The mushroom culture medium comprises dry materials and water; by setting the weight of the dry materials to be 100 parts, the dry materials are composed of following components by weight percent: 20%-50% of the coffee grounds, 28%-58% of cotton seeds, 15%-20% of wheat bran, 1%-2% of gypsum and 1%-2% of lime. The mushroom culture medium is specifically prepared as follows: recycling and concentrating the waste coffee grounds and drying; crushing the coffee grounds until the diameter is 0.1cm-0.5cm; uniformly mixing the crushed coffee grounds with the cotton seeds, the wheat bran, the gypsum and the lime according to the weight ratio; adding water to enable the water content to be 60%-70% to prepare a primary material; and sterilizing the primary material for 1-1.5 hours under the conditions that the density is 1.5kg/cm<2> and the temperature is 121 DEG C and cooling. According to the mushroom culture medium prepared from the coffee grounds, the coffee grounds are used for replacing a sawdust part to provide necessary components including cellulose and the like; the growing of mushrooms is accelerated; the content of heavy metal of the mushrooms is reduced due to utilization of physical and chemical adsorption of the coffee grounds and no pesticide residue exists.

Description

technical field [0001] The invention belongs to the technical field of mushroom planting, and in particular relates to a mushroom culture medium prepared from coffee grounds. Background technique [0002] The growth and development of mushrooms requires nutrients such as carbon sources, nitrogen sources, minerals, and vitamins; in the production of mushrooms, the existing technology often uses solid medium mainly made of wood chips, supplemented by bran, cotton seeds, etc. as mushrooms. source of nutrition. At the same time, since most of the mushrooms belong to woody fungi, the main culture medium is broad-leaved wood chips, which require considerable forest resources to meet the needs of the mushroom industry. Therefore, the development of the mushroom industry also leads to the balance between mushroom production and forestry ecology If the contradiction is not resolved, the mushroom industry is bound to face the dilemma of unsustainable development as the forest area gr...
