Description
Technical field
The invention belongs to excrement and urine treatment technology fields, specifically, are related to a kind of method handling excrement using black soldier flies
And its organic fertilizer prepared.
Background technology
Currently, as people are more and more stronger to the consciousness of environmental protection, by people's the problem of environmental pollution and resource
Greatly concern rationally utilizes resource, turns waste into wealth, resource circulation utilization.And black soldier flies, fly maggot and earthworm etc. in aquaculture industry
Industry is a dark horse, and especially the excrement that livestock excludes can be effectively converted to organic fertilizer, while output high quality by black soldier flies
Protein.
In the prior art, often worm's ovum is linked into excrement, after egg hatch, by larval feeding excrement, to real
The processing of existing excrement, but since the mouthpart of insect larvae has a degree of degeneration, and prior art is often direct
Excrement is directly fed larva to eat, larva feed is not easy in this way, and be unfavorable for digesting and assimilating for larva, can substantially reduce
The yield for handling the efficiency and organic fertilizer of excrement, reduces the yield of larva, to influence the yield and quality of insect protein, and has
In order to pursue the quality and yield of insect larvae, then various nutrients are directly added into excrement：As meat meal tankage, feather meal,
Globulin powder etc. has so then been correspondingly improved the cost of the cost and breeding insects larva of night soil-treatment.
Invention content
In order to solve the above technical problems, the purpose of the present invention is to provide it is a kind of using black soldier flies handle excrement method and
Its organic fertilizer prepared can fast and effeciently degrade manure fermentation to the degree conducive to insect larvae feeding, without adding it
His nutrients equally can efficiently convert excrement and obtain the larva of high yield, largely reduce cost.
A kind of organic fertilizer for method and its preparation handling excrement using black soldier flies that the object of the invention is realized in,
Key is to comprise the steps of：
A, the pretreatment of excrement:It is 1 by ratio of weight and the number of copies by raw ferment agent and degradation agent:1 ratio is mixed and made into microbial inoculum；It is accurate
Standby excrement；Microbial inoculum is weighed by the 0.02~0.04% of stool weight；It is weighed containing sugared coarse grain powder by the 3~5% of stool weight；Then
It is added in excrement after being stirred containing sugared coarse grain powder and microbial inoculum and continues to stir, then mixture is being fermented at 25~30 DEG C
Closed processes 12-24h in pond；
B, it is inoculated with larva：Pretreated excrement is tiled, then by black soldier flies egg hatch at larva after, then by larva
It is linked into excrement, handles 10~20 days, the ratio of the black soldier flies worm's ovum and excrement is 100~200 g tons；
C, material worm separation：The addition sawdust or/and chaff powder into material worm mixture, stir evenly make humidity be reduced to 20~
50%RH, then Separation by vibration go out material residue and fresh worm.Sawdust or/and chaff powder, which is added, can reduce the humidity of material worm mixture, be convenient for
Screening separation, and it is at low cost.
" fun farm " degradation of Sichuan harmony bio tech ltd production may be selected in above-mentioned raw ferment agent and degradation agent
Agent and raw ferment agent.
Above-mentioned excrement is the bulk excrement that water content is 65~70%.
Above-mentioned excrement is chicken manure, duck excrement, pig manure, cow dung or horsehit.
The coarse grain powder containing sugar is corn flour, paddy chaff powder, cane powder or sweet potato powder in above-mentioned steps a, these powders are common
Crop is made, at low cost.
Above-mentioned steps b inoculation larvas are specially that pretreated excrement tiles, then by black soldier flies egg hatch at children
It is linked into excrement after worm, 10~20 is handled under indoor temperature is 25~30 DEG C, humidity is 50~70%RH and low light condition
It, the ratio of the black soldier flies worm's ovum and excrement is 100~200 g tons.Since black soldier flies larva has photophobism and the seam that becomes
Property, and worm's ovum is directly seeded in excrement surface by while being inoculated with, under low light condition, the photophobism of larva and the seam property that becomes make larva
Preferably night soil-treatment can be fallen from top to bottom, substantially increase the handling rate of excrement.
The thickness that excrement tiles in above-mentioned steps b is 10~20cm.
Worm mixture is expected in above-mentioned steps c:Sawdust or/and chaff powder=1:1.
A kind of organic fertilizer, key are：Pass through a kind of above-mentioned method and its preparation handling excrement using black soldier flies
Organic fertilizer be prepared.
Advantageous effect：
A kind of organic fertilizer for the method and its preparation handling excrement using black soldier flies of the present invention, by raw ferment agent to excrement into
Row fermentation, and degraded to excrement by degradation agent, night soil-treatment is extremely conducive to the semi-fluid state of insect larvae feeding, from
Without adding other nutrients, the conversion ratio that the excrement that makes that treated can be used as organic fertilizer reaches 55~75%, while 1 ton
Excrement energy output larva yield reaches 100~300kg, thus largely reduces night soil-treatment cost, reduces excrement
Influence to environment, and the insect protein of high value and organic fertilizer full of nutrition have been obtained, it is to achieve many things at one stroke.
