Abstract
The present invention is a kind of preparation method of charcoal organic fertilizer, specific step is as follows for its preparation: straw, foaming agent and degradable resin being mixed charing first, charcoal is made, then the obtained organic fertilizer wet feed that ferments is carried out with microbial bacterial agent and decomposing agent after the fermentation of excrement and stalk crushes, then charcoal organic fertilizer is made in charcoal, organic fertilizer wet feed, deodorant and compound fertilizer's combination drying, the cooling of charcoal organic fertilizer granulation is finally obtained into charcoal base organic fertilizer product.The present invention is by the way that charcoal to be added in organic fertilizer, pass through charcoal macropore and aperture coordinative role, improve the heavy metal pollution in soil, while the utilization of stalk can solve current organic waste burning bring problem of environmental pollution, turn waste into wealth, the deodorizing process twice of last excrement not only significantly improves feces of livestock and poultry bring malodor problem, and the fertilizer efficiency time of charcoal organic fertilizer is long, and slow release effect is good, scientific and reasonable, it is environmentally protective, it is environmentally friendly.
Description
Technical field
The present invention relates to organic fertilizer technical field more particularly to a kind of preparation methods of charcoal organic fertilizer.
Background technique
With the continuous promotion of agricultural products in China export ratio, requirement of the agricultural for fertilizer, soil fertility will constantly be risen
Grade.Therefore, the angle that the change from soil and fertilizer type and fertility are promoted is come using charcoal base manure material, will be to China's agricultural knot
The adjustment of structure and the promotion of export of farm produce comprehensive strength generate great progradation.
China's agricultural production and life in the countryside generate a large amount of biomass castoffs, and recycling treatment pressure increasingly increases.I
State's agricultural crop straw quantity is big, type is more, distribution is wide.According to statistics, all kinds of stalks in 2010 collect about 700,000,000 tons of amount, synthesis
Utilization rate 70.6% accounts for about the 73% of national total amount wherein 13 major grain producing areas are about 500,000,000 tons.It has basically formed at present
The polynary pattern utilized of agricultural stalk Fertilizer Transformed, fodder, base-material, raw material, turning sludge into fuel.But generally speaking, agriculture waste
Object recycling degree is low, and comprehensive utilization scope of the enterprise is small, lacks leading enterprise and drives, industrialized development is slow.
Currently, serious heavy metals exceeding standard event occur in more ground crops, tremendous influence is brought to agricultural and sideline work enterprise.Simultaneously
Quite a few agricultural wastes does not obtain efficient resource utilization, not only waste of resource, but also causes environmental pollution, crops straw
The random stacking of stalk.
Summary of the invention
Present invention seek to address that the deficiencies in the prior art, and a kind of preparation method of charcoal organic fertilizer is provided.
The present invention to achieve the above object, using following technical scheme:
A kind of preparation method of charcoal organic fertilizer, specific step is as follows for preparation:
(1) charcoal is prepared
It is mixed after 100 parts of straw are crushed by weight with 1~10 part of foaming agent, 1~10 part of degradable resin, it will
Mixture is placed in retort, takes out 30~40min of oxygen after closing retort, when oxygen content is down to 1% or less in retort into
Row charring process, is made charcoal；
(2) fermentation of excrement and stalk
It by bacteria residue, animal excretion, stalk, charcoal grinding and sieving, is uniformly mixed, puts into fermentation vat, and fermenting
Microbial bacterial agent and decomposing agent are put into pond, fresh air is filled with into fermentation material, are made temperature control at 65~70 DEG C, are turned over throwing,
Cool down to fermentation material, moisture content reduces, and end is fermented up to organic fertilizer wet feed；
(3) preparation of charcoal organic fertilizer
By weight by 15~18 parts of charcoal, 50~60 parts of organic fertilizer wet feed, the first 2~4 parts of deodorant, the second deodorization
6~8 parts of agent, 8~12 parts of compound fertilizer, 2~3 parts of wood vinegar mixing after be added gelatin, humic acid, then by obtained mixture into
Row, which is dried, is made charcoal organic fertilizer；
(4) it is granulated cooling
The charcoal organic fertilizer that step (3) obtains is granulated, cooling, sieving is to get charcoal base organic fertilizer product.
Particularly, the charring process in step (1) is at 190~210 DEG C of temperature, and 30~35min of the time carries out the first step
Dehydration procedure, then at 520~540 DEG C of temperature, 4~5h of carbonization time carries out charing process, will finally carbonize in-furnace temperature
110~130 DEG C are down in 1min, 50~60min of time is carried out cooling process.
Particularly, the microbial bacterial agent in step (2) are as follows: JT microbial bacterial agent, EM microbial bacterial agent, aspergillus niger microbial inoculum,
One or both of bacillus subtilis, lactobacillus plantarum.
Particularly, the fermentation temperature in step (2) is 40~60 DEG C, and fermentation material moisture content is 50~60%；The fermentation
Time is 7~15 days.
Particularly, the first deodorant in step (3) is zeolite powder, attapulgite or coal ash, and the second deodorant includes pressing
15~20 parts of the bacillus subtilis of parts by weight meter, 30~40 parts of Bacillus acidi lactici and 20~30 parts of saccharomycete.
Particularly, the compound fertilizer in step (3) includes 10~15 parts of 15~25 parts of nitrogenous fertilizer, phosphate fertilizer and potassium by weight
10~15 parts of fertilizer.
The beneficial effects of the present invention are: the present invention is by the way that charcoal to be added in organic fertilizer, by charcoal macropore and small
Hole coordinative role, improve soil in heavy metal pollution, while stalk using can solve current organic waste combustion zone come
Problem of environmental pollution, turn waste into wealth, the deodorizing process twice of last excrement not only significantly improves feces of livestock and poultry bring stench
Problem, and the fertilizer efficiency time of charcoal organic fertilizer is long, slow release effect is good, and it is scientific and reasonable, it is environmentally protective, it is environmentally friendly.
