Drumstick mushroom culture medium and preparation processing method thereof

Abstract

The invention belongs to the field of edible fungus production, and discloses a drumstick mushroom culture medium and a preparation method thereof. The culture medium comprises manioc waste, vinegar residue, germ bran, crop straw powder and other industrial and agricultural waste. The preparation method comprises the following steps: dissolving magnesium sulfate and monopotassium phosphate in water to prepare nutrient solution; uniformly stirring the manioc waste, the vinegar residue, the germ bran, the crop straw powder, cotton seed hulls, bran, gypsum powder, lime powder and other dry materials to form mixed material; adding the nutrient solution into the mixed material to keep on stirring; composting when moisture is completely absorbed by all the dry materials; and packaging and sterilizing after 5 to 10 days. The drumstick mushroom cultured by the culture medium not only can reduce pollution of the industrial and agricultural waste to the environment, but also can reduce the production cost of the drumstick mushroom by 30 to 50 percent, so two aims can be achieved at once.

Description

technical field [0001] The invention relates to an edible fungus cultivation substrate, in particular to a low-carbon Coprinus comatus cultivation substrate and a preparation and processing method thereof, belonging to the technical field of edible fungi production. Background technique [0002] Coprinus comatus is one of the rare edible fungus varieties with rapid development in recent years. It is a saprophytic fungus with strong adaptability. It has been recognized as a collection of "natural, nutritious and One of the 16 rare edible fungi with the characteristics and functions of "health care" and "health care", it is being vigorously promoted all over the world. For a long time, most of the edible fungus varieties in my country have been cultivated with cottonseed husks as the main raw material. At present, the price of cottonseed husks has risen from 1,000 yuan / ton in 2001 to 1,900 yuan / ton, and the cost for farmers to grow mushrooms has greatly increased. . In the pr...

For a long time, most of the edible fungus varieties in my country have been cultivated with cottonseed husks as the main raw material. At present, the price of cottonseed husks has risen from 1,000 yuan / ton in 2001 to 1,900 yuan / ton, and the cost of growing mushrooms for farmers has greatly increased.

In the prior art, although Coprinus comatus can be cultivated by using the leftovers of edible fungi to replace part of the cottonseed husks, if the substitution amount exceeds 50%, it is prone to the phenomenon that the rate of finished products is not high and the output is unstable

Vinegar grains, cassava residues, and straws of crops such as corn, rapeseed, rice, and wheat are leftovers from industry and agriculture, and they all belong to organic wastes. The quantity is huge, and if they are not disposed of in time, they will easily cause environmental pollution; especially straw, Most farmers return it to the field as fertilizer or as fuel, without giving full play to its use value, and some farmers directly burn it in the farmland, causing serious pollution to the environment and becoming a social problem that has been banned by governments at all levels for a long time
