Abstract
The invention discloses a kind of method that utilization biogas slurry, biogas residue, feces of livestock and poultry, edible animal human body etc. prepare efficient organic fertilizer, it is characterized in that, the organic fertilizer is to be prepared from by biogas slurry, biogas residue, livestock and poultry animal excrement, edible animal human body etc. for raw material, wherein respectively biogas residue 15 20%, livestock and poultry animal excrement 60 70%, edible animal human body etc. 5%, humic acid 5% are constituted the organic fertilizer in mass.Stalk anaerobic hydrolysate 1 5% is added in organic fertilizer wherein per ton.The efficient organic fertilizer of the present invention is prepared according to During High-Temperature Composting and pyrohydrolysis acidization tool.Obtained efficient organic fertilizer can be with direct returning to farmland, it need not topdress, with cost is low, high benefit, environmental protection the characteristics of, the point-source pollution of biogas slurry, biogas residue, feces of livestock and poultry and the edible animal human body can be solved the problems, such as, the secondary pollution problem that their direct returning to farmland may be brought can also be reduced, Production Time and the cost of organic fertilizer is substantially reduced.
Description
Technical field
The present invention relates to technical field of biological fertilizer, and in particular to a kind of preparation method of efficient organic fertilizer.
Background technology
The chemical fertilizer usage amount of China's agricultural is big, and the soil organism is seriously degenerated, and soil tillage is hardened.At the same time,
Biogas slurry, the biogas residue produced in anaerobic fermentation process, although nutriment enriches, but also there is secondary environmental pollution in direct use
The problem of.Charcoal can effectively adsorb many kinds of substance as porous mass, but the direct of charcoal uses, and it is in soil
It can not decompose or be absorbed by plants, so as to be unfavorable for the reparation of soil.
The problem present on solving above-mentioned agricultural production, gives full play to the advantage of charcoal, the present invention is using biogas residue as original
Material prepares charcoal, and then manufactures carbon-base slow release fertilizer by matrix of charcoal and be applied to agricultural production, efficiently solves
State problem.This technology is applied fertilizer by slow control, can preferably control the rate of release of nutrient in fertilizer, is simplified fertilising flow, is realized
The need for single fertilization meets plant whole growth period, have the advantages that utilization rate of fertilizer is high, lose less, it is environment-friendly, it is real
Existing unification between fertilizer, crop and environment in economic benefit and ecological benefits.
The content of the invention
It is an object of the invention to for the above-mentioned technical problem to be solved provide it is a kind of with biogas slurry, biogas residue, feces of livestock and poultry,
Edible animal human body etc. is raw material, and a kind of method of efficient organic fertilizer is prepared using biomass solid waste.Obtained using this method
Organic fertilizer has nutritious, is not required to topdress, and improves lean soil environment, and alternative chemical fertilizer is used for a long time, farming is realized
Organic plantation of thing.
This method is prepared according to high temperature matured compost and pyrohydrolysis acidization tool.Made using the porous adsorptivity of charcoal
For the carrier material of organic fertilizer, the efficient organic fertilizer for coordinating humic acid to prepare realizes the green of biomass solid waste, circulation, efficient
Utilize.
To realize above-mentioned technical purpose, the technical solution adopted by the present invention comprises the following steps：
1）Biogas residue is dried, crushed, crossing 20 eye mesh screens（Take the lower rate of sieve）, in 105 DEG C of dry for standby；
2）Biogas residue high-temperature calcination charcoal, calcination condition is：Heated under high temperature process furnances, nitrogen atmosphere, be pyrolyzed heating rate
For 25 DEG C/min, pyrolysis temperature is to be pyrolyzed 3h under 600 DEG C of states.Cooling, is dried, grinding, and 80 eye mesh screens screening, kept dry is treated
With；
3）Prepare and be rich in phosphorus carrier：Plus biogas slurry soaks the materials such as the edible animal human body, sealed after being sufficiently mixed, in 70-80 DEG C of bar
High temperature matured compost 5-15 days under part（It is defined by juice in black, the time can adjust）；
4）Feces of livestock and poultry, dries, crushes, crossing 20 mesh sieves（Take the lower rate of sieve）, save backup；
5）All substances are mixed in proportion, organic fertilizer product is made 30% or so in the humidity of biogas slurry control organic fertilizer.
The advantages of the present invention are：
This method technique is simple, easy to operate, and cost is low, social effect and remarkable in economical benefits；It can improve in existing lean soil
Organic matter lacks, and meets crops and grows demand substantially；Charcoal sticking fertilizer nutrient, slow controlled release improves fertilizer and supported
Divide utilization rate；Fertilizer elution loss is reduced, and mitigates the problem of environmental pollution produced by fertilizer loss.
