Method for utilizing hermetia illucens to dispose feces of poultry and livestock

Abstract

The invention provides a method for utilizing hermetia illucens to dispose feces of poultry and livestock. The method includes the steps of (1) collecting the feces of the poultry and livestock, stirring and mixing sugar-contained coarse food grain with a fungicide, then adding the mixture into the feces for stirring, conducting sealing treatment on the mixture in a fermentation pond for 12-24 hours to obtain a raw material for feeding, and then uniformly spreading out the raw material for feeding; (2) inoculating 6-8-day-old larvae of hermetia illucens into the raw material for feeding, wherein the raw material for feeding is supplied to and eaten by the larvae of hermetia illucens, and bioconversion is carried out for 6-10 days; (3) after the raw material for feeding is converted to small loose granular residues, conducting separation of the larvae and the residues to obtain the larvae of hermetia illucens and remaining residues; (4) using the larvae of hermetia illucens as feed or high-protein insect larvae, and adopting the remaining residues for making efficient solid organic fertilizer. By means of the method, the feces can be quickly and efficiently fermented and degraded tothe degree suitable for being eaten by the insect larvae, efficient conversion of the feces can also be achieved without adding other nutrients, a high yield of larvae can be obtained, and the cost is reduced to a great extent.

Description

technical field [0001] The invention relates to the technical field of resources and environmental protection, in particular to a method for treating poultry manure by using black soldier flies. Background technique [0002] At present, as people's awareness of environmental protection is getting stronger and stronger, the problems of environmental pollution and resources have received great attention from people, rational use of resources, turning waste into wealth, and recycling of resources. In the breeding industry, industries such as black soldier flies, fly maggots and earthworms have sprung up. In particular, black soldier flies can effectively convert the feces excreted by livestock into organic fertilizers, and at the same time produce high-quality protein. The black soldier fly belongs to the Diptera Soldier Fly family and is a worldwide distribution insect. Black soldier flies can effectively reduce the accumulation of feces, the smell of feces, and prevent the b...

Problems solved by technology

[0003] In the prior art, the eggs are often inserted into the feces, and after the eggs hatch, the larvae feed on the feces, thereby realizing the treatment of the feces. However, due to the degeneration of the mouthparts of the insect larvae, the existing technology The solution is often to feed the feces directly to the larvae, which is not convenient for the larvae to eat, and is not conducive to the digestion and absorption of the larvae, which will greatly reduce the efficiency of manure processing and the yield of organic fertilizer, reduce the yield of larvae, and thus affect the yield of insect protein and quality, and some in order to pursue the quality and output of insect larvae, then directly add various nutrients to the feces: such as meat and bone meal, feather meal, blood globulin powder, etc., so that the cost and cost of manure treatment are correspondingly increased.
