A cultivation medium for increasing the output of cup mushroom and its preparation method

Abstract

The invention discloses a cultivation medium capable of increasing the yield of big clitocybe and a preparation method thereof. The cultivation medium comprises nutrient media and cover-soil materials of which the weight ratio is 2-3 to 1; the nutrient media are prepared from, by weight, 60-70 parts of mulberry twig stalk powder, 15-20 parts of tea tree dregs, 8-12 parts of sheep manure, 5-8 parts of bran, 3-6 parts of corn powder, 2-4 parts of phosphorus fertilizer, 0.5-1.5 parts of lime, 1-2 parts of plaster and 0.5-1.5 parts of derris powder; the cover-soil materials are prepared from, by weight, 25-30 parts of fine soil, 12-15 parts of sucrose silt, 2-3 parts of sodium selenite and 1-2 parts of bacillus thuringiensis. The cultivation medium is rich and comprehensive in nutrient, the nutritional requirement of growth development of the big clitocybe can be met, and the cultivated big clitocybe is large in size, high in growth velocity and high in disease resistance; compared with a conventional cultivation medium, mushrooms are picked about 10 days in advance, and the yield is increased by about 20 percent. The raw materials of the cultivation medium are wide and easy to obtain, the cost is low, the production process is simple, and the cultivation medium is suitable for large-scale cultivation of the big clitocybe.

Description

technical field [0001] The invention relates to the technical field of edible mushroom cultivation, in particular to a cultivation medium for increasing the yield of cup mushroom and a preparation method thereof. Background technique [0002] Clitoeybe maxima (Clitoeybe maxima), also known as Pork Belly Mushroom, Clitoeybe maxima, belongs to Basidiomycetes, Agaricaceae, Trichomonaceae, and Clitoeybe maxima. The large cup fungus fruit bodies are grouped or solitary, cup-shaped or shallow-funnel-shaped, light yellow, with thick flesh and thick stalk. The fruit body of cup mushroom has a crisp, tender and delicious taste, and its protein content is similar to that of Flammulina velutipes. The amino acid content in the cap is about 17% of the dry matter, among which 8 kinds of essential amino acids account for 45% of the total amino acid content, which is higher than that of common edible fungi, and its content of leucine and isoleucine ranks first in common edible fungi The c...
