Embodiment 1

[0031] (1) Check the heavy metal content of the collected organic perishable garbage. Heavy metals include arsenic, lead, cadmium, chromium, mercury, zinc, and copper. If any of the above elements seriously exceed the standard, it will be landfilled. If the above elements If none of them seriously exceeds the standard, mix them;

[0032] (2) Mix organic perishable waste with auxiliary material A. The auxiliary material A is composed of straw, wheat bran and sawdust. The weight ratio of the three is 1:1.5:0.8. After mixing, screening, crushing, sterilization, Pulping to obtain organic perishable waste slurry;

[0033] (3) Adjust the pH value of the slurry to 7.2, and control the water content of the slurry at 66%;

[0034] (4) Take the slurry obtained in step (3) and mix it with auxiliary material B, and then add a composite strain of 1% of the total weight of the two. The composite strain includes 30 parts of Bacillus licheniformis, 15 parts of yeast, and 20 parts of white ro...

Abstract

The invention discloses a method for preparing feed for breeding black soldier flies with organic perishable garbage. The method uses organic perishable garbage as feeding raw materials, and is equipped with various auxiliary materials and compound strains of optimal design to realize the breeding of black soldier flies. Efficient farming. The breeding method of the invention can meet the requirements of black soldier fly breeding, can improve the feeding efficiency and survival rate of black soldier fly larvae, and can fully utilize the nutrients in the organic perishable garbage to realize rapid conversion and utilization. The invention makes secondary use of waste resources such as organic perishable garbage, straw, and bean dregs, and is simple in operation, low in cost, low in carbon and environmentally friendly, and high in economic value, and provides a basic solution for large-scale and industrialized breeding of black soldier flies.

Description

technical field [0001] The invention relates to the field of black soldier fly breeding, in particular to a method for preparing feed and breeding black soldier fly with organic perishable garbage. Background technique [0002] Organic perishable waste, also known as wet waste, mainly comes from agricultural production and domestic waste, mainly including: feces, dross, filter mud, kitchen and vegetable market waste, etc. A wide variety of organic matter, this type of waste is perishable in the natural environment Deterioration becomes a source of pollution that hinders normal production and life, causing environmental hazards. On the other hand, organic perishable waste contains a lot of nutrients, and if it can be reused, it will be a huge asset. [0003] The black soldier fly (Hermitia illucens) is a kind of insect belonging to the genus Soldieri in the Soldieridae family of Diptera, also known as the bright Soldier Fly, which is distributed in most parts of the tropics ...
