Method for industrially culturing needle mushroom by utilizing soybean stalks

Abstract

The invention belongs to the field of edible mushroom production, and discloses a method for industrially culturing needle mushroom by utilizing soybean stalks, which comprises the following steps of: collecting and processing the soybean stalks; making a formula of a soybean stalk culture medium; preparing the culture medium; bottling and holing; sterilizing and inoculating; culturing mycelium; controlling temperature and compensating light for promoting buds; covering a plastic film; harvesting and packaging; and cleaning bottles. The method is characterized in that: the formula of the culture medium comprises 40 to 55 percent of soybean stalk, 25 to 35 percent of bran, 8 to 15 percent of corn meal, 8 to 12 percent of sawdust, 1 to 2 percent of light calcium carbonate and 55 to 65 percent of water. The utilized soybean stalks are rich in nutrition and low in price, and has the nutritional ingredient content not lower than that of cotton seed hulls and corncobs, but only costs 1 / 4-1 / 2 of the cotton seed hulls; and the soybean stalks instead of the cotton seed hulls for industrially culturing the needle mushroom can reduce the production cost by 28 to 35 percent and can be promoted and applied across the country.

Description

technical field [0001] The invention relates to a cultivation substrate and a cultivation method of Flammulina velutipes, in particular to a method for industrially cultivating Flammulina velutipes by using bean stalks, belonging to the field of edible fungus production. Background technique [0002] Flammulina velutipes is one of the main products of edible fungi in my country. The emergence of Flammulina velutipes factory cultivation technology not only improves the yield and quality, but also breaks the seasonal restrictions and realizes annual production, especially changing the consumption and supply of the summer market. The growth and development of Flammulina velutipes requires nutrients such as nitrogen source, carbon source, cellulose, minerals and trace elements. In the prior art, the cultivation of Flammulina velutipes mainly uses organic matter such as cottonseed shells, corncobs, and sawdust as raw materials. A daily output of 5 tons of fresh mushrooms Small a...

At present, the utilization rate of soybean straw is less than 3%. Except for a small amount of industrial raw materials, it is mainly used as feed for cattle and sheep, which is unreasonably willing to be eaten. A large amount of soybean straw is burned as fuel, resulting in a great waste of precious resources.
