Description
Technical field
The present invention relates to organic fertilizer preparation technical field, specially a kind of method using pig manure production organic fertilizer.
Background technique
Pig is treasured from head to foot, has no waste, and pig manure is all the perfect fertilizer of agricultural.Pig raising is made money, and pig manure fertilizes the soil." grain is more
Pig is more, and pig polycopria is more, and the more grains of excrement are more " it is kind of a benign ecological agriculture circulation.Pig manure quality is thinner, containing more organic matter and
Npk nutrient, it is suitable for making base manure, the excrement of a pig can increase production 200-300 jins of grain that pig manure decomposition is slower.But people are logical
Often think that pig is very dirty animal, pig is liked cleanliness very much in fact.In pigsty, the problems of livelihood of pig has fixed position
It sets.Under the conditions of modernized pig raising, swine manure treatment is a crucial environmental protection technology, otherwise can cause environmental pollution.Through overfertilization
The scientific disposal for expecting leavening, can be reached no pollution, zero-emission and odorless, be made muck with the high-quality organic fertilizer of swine excrement addition
Become gold.
And after pig manure is prepared into organic fertilizer by general technology, there can be heavy-metal residual, and exist in organic fertilizer
A small amount of aflatoxin B1 and salmonella has damaging effect, and effect is not strong, can not increase the organic matter of soil
With improvement soil.
Therefore we have proposed a kind of methods using pig manure production organic fertilizer to be prepared by special preparation method
The organic fertilizer of excellent effect.
Summary of the invention
(1) the technical issues of solving
In view of the deficiencies of the prior art, it the present invention provides a kind of method using pig manure production organic fertilizer, solves existing
Some pig manures prepare the problem of organic fertilizer effect is bad and harmful residual of the method preparation of organic fertilizer.
(2) technical solution
To achieve the above object, the invention provides the following technical scheme: a kind of method using pig manure production organic fertilizer, packet
Include following steps:
The production of butt matter pig manure main material:
A1, by the fresh pig manure of water content 70% or so, be exposed to the sun with hardened ground, turn over throwing 2-3 days, make moisture content up to 40% or so
Afterwards, stacking after throwing is turned over after exchanging uniform by 300-500 grams of strain per ton, 1.5 meters of height of embankment or so, wide 5 meters of heap or so, heap length can be because of place
And determine, 60 DEG C of pile Nei Wenduda or so are measured through electronic temperature sensing device, is kept for 3 days；
A2, second of turning: first time stacking, through temperature measuring, throwing is turned in beginning in 5 days for the second time, can be according to cross section feelings
Condition suitably adds 100 grams per ton or so microbial inoculums again.Handling the time is 4 days；
A3, third time turning: after second of processing four days, then throwing processing is turned over three times, handled the time general four days；
A4, the 4th turning: same third time, if moisture content is up to 20%, through processing measurement judgement, as strain number surpasses 2,000 ten thousand/
Gram, roundworm egg is detected as zero, then it is stand-by to ted packing；
A5, the main material for being up to every detection index first carry out feed grade crushing, after pulverized after be packaged it is standby
With；
Bioengineering processing:
S1, the processing of first time bioengineering: 1, it configures major ingredient: the fresh pig dung of water content 50%-70% and early period has been located
Manage the 15% strain content of water content that processes not less than 2,000 ten thousand/gram, the pig manure main material pulverized, addition per ton
300 grams or so of strain, progress is full and uniform to turn over throwing, and fresh pig dung and pig manure main material ratio are generally 5: 1, should be according to practical need
It measures and converts moisture content up to subject to 40% or so.Stacking, 1.5 meters of height of embankment or so, wide 5 meters of heap or so, heap length can determine because of place
Calmly, heap face will polish flat smooth, cover transparent waterproof cloth rainy days.Electronics survey meter measuring temperature is used after 2 days, temperature is up to 60 DEG C
Left and right is advisable, then is kept for 3 days.Heap cross section, which is uniformly distributed a large amount of strains of snowflake sample, to be advisable；
S2, second of bioengineering processing: the stacking for handling 5 days through first time bioengineering open and turns over throwing, to
After turning over throwing uniformly, no snowflake growth district adds strain in right amount, then proceedes to, and such as clamp method stacking processing 4 days again of S1；
S3, the processing of third time bioengineering: with 2 steps；
S4, the 4th secondary pollutant project treatment: with 3 steps, but the time is determined by water content and indices.
S5, crushing and processing: 1. stacking opening is exposed to the sun, frequently turns over throwing, indices is detected, after up to standard, chooses waste product；②
High-power 30 kilowatt/hour motor of pulverizer, goes out one ton of product for one hour, within 40 mesh of sieve, is crushed；3. by 40 mesh
The pig manure main material crushed, which crushes 11 kilowatt/hour of micronizer power through micronizer again, to be advisable, sieve 300-500
Nanometer is advisable；
S6, biology granulation: plain grinding, ring mill can be with 30 kilowatts/hour of machine power；
Aperture:MillimeterMillimeterMillimeterMillimeter；
S7, cooling air-drying: make particle moisture content up within 13% with low-power fan filtering type is point dry；
S8, dress packet, labeling, quality inspection and factory sale.
(3) beneficial effect
The present invention provides a kind of methods using pig manure production organic fertilizer.Have it is following the utility model has the advantages that
(1), organic fertilizer prepared by the present invention, there is no heavy-metal residuals, and there is no aspergillus flavus poison in organic fertilizer
Plain B1 and salmonella, so that the organic fertilizer effect of being safe from harm, and effect is very strong, additionally it is possible to and increase the organic matter of soil and changes
Kind soil.
(2), organic fertilizer prepared by the present invention contains crude protein, coarse ash, crude fat, crude fibre and 17 kinds of hydrolysis amino
Acid, it is completely different with former pig manure detection ingredient, pollution is not constituted, and environmentally protective, can increase sharply the soil organism, improvement
Soil can make that fruits and vegetables is hyperchromic, sweetened and volume increase largely using harmless, and return to primitive age taste can be by farming article
Matter is promoted completely.
