Method for producing fish feed by utilizing mushroom dregs

Abstract

The invention provides a method for producing fish feed by utilizing mushroom dregs. The method comprises the following steps: (1) adding 1 to 3% limewater, in an amount which is 0.3 to 0.5 time the weight of the mushroom dregs, into the mushroom dregs, repeatedly rolling for 30 to 40 minutes, and performing microwave drying after rolling to obtain dried mushroom dregs; (2) weighing the followingraw materials in parts by weight: 50 to 70 parts of dried mushroom dregs, 30 to 50 parts of corn powder, 12 to 19 parts of soybean meal, 2 to 6 parts of earthworm dry powder, 1 to 3 parts of cicada pupa, 0.02 to 0.05 part of composite vitamin, 0.01 to 0.02 part of composite amino acid, mixing the raw materials, adding a proper amount of water, pelletizing and drying to obtain the fish feed. The mushroom dregs are subjected to disinfecting and drying treatment and are reused for producing the fish feed, so that the production cost of the edible mushroom is greatly reduced; furthermore, the mushroom dregs are subjected to effective pollution-free treatment.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for producing fish feed by utilizing fungus residue. Background technique [0002] Ecological breeding is a production mode vigorously advocated by our country at present. Its biggest feature is that within a limited space, different kinds of animals and plant groups are artificially connected in series with feed or fertilizer to form a circular chain. It is to maximize the use of resources, reduce waste, reduce pollution and reduce costs. [0003] Mushroom residue refers to the solid waste left after the cultivation of various edible fungi. At present, my country has become the largest producer of edible fungi in the world, and the cultivation of edible fungi has developed into three major rural industries with equal emphasis on planting and breeding, and has become the most dynamic emerging sunrise industry in my country's rural economy. With the expansion of t...

Problems solved by technology

Because there is no effective recycling method, edible fungus residues can be seen everywhere in the villages, river banks, field corners, and front and back of houses that produce edible fungi in the surrounding areas of Chengdu. Such treatment of mushroom residues not only leads to waste of resources, but also causes The breeding of mold harmful spores and pests, causing great pollution to the environment
