Description
Technical field
The invention belongs to technical field of fertilizers, and in particular to a kind of high-activity humic acid ecology compound fertilizer.
Background technique
For many years chemical fertilizer generally being done using for agricultural development, increasing peasant income and rural area prosperity in China's agricultural production
Tremendous contribution is gone out.But chemical fertilizer is largely used for a long time, it is excessively high to also result in soil salt content, harmful ion concentration mistake
Greatly, structural difference, easy to harden, fertility is unbalanced in soil, and fertility decline, crop growth is restricted.The data shows that
China's soil pollution is got worse, saline-alkali soil rapid development.Improvement soil, preserving the ecological environment has caused the Chinese government
Pay much attention to, therefore China proposes the target of the year two thousand twenty chemical fertilizer zero growth rate.Currently, humic acid in humic acid fertilizer in the market
Most of production method be using weathered coal, peat, lignite etc. through the broken original powder produced, in humic acid " activated centre
It " is not fully opened, Industry code requirements are not achieved in activation humic acid content, and the effect of humic acid cannot embody, using effect
It has a greatly reduced quality.
Summary of the invention
In view of this, the present invention is directed to propose a kind of high-activity humic acid ecology compound fertilizer, passes through weathered coal or lignite
It is acidified, the processing of ammonification and bioactivation, improves the quantity of humic acid activity functional group, enhance the effect of humic acid；Pass through
Plant growth regulator is added, reaches and improves crop quality and yield, enhances the purpose of crop disease-resistant ability；Utilize weight peroxophosphoric acid
The distinctive viscosity of calcium is realized and is granulated without filler material, and products material cost is reduced.
In order to solve the above technical problems, the technical solution adopted by the present invention is that: a kind of high-activity humic acid ecology compound fertilizer
Material, urea Zhan always puts into the mass percent 22%-52% of material quantity, potassium chloride Zhan always puts into the mass percent of material quantity
15% -32%, double superhosphate Zhan always puts into the mass percent 5% -8% of material quantity, monoammonium phosphate Zhan always puts into material quantity
It is total that mass percent 12% -40%, weathered coal or lignite Zhan always put into the mass percent 6%-10% of material quantity, phosphoric acid solution Zhan
Mass percent 3%-5%, the ammonium hydroxide Zhan of investment material quantity always put into the mass percent 1.5%-2.5% of material quantity, activation microbial inoculum
Zhan always puts into the mass percent 2%-2.5% of material quantity, plant growth regulator Zhan always puts into the mass percent of material quantity
0.5%-1%；
The preparation method of the high-activity humic acid ecology compound fertilizer, comprising the following steps:
(1) preparation (spare) of high-activity humic acid
The preparation of 1.1 humic acid original powders: being crushed to 100-120 mesh for the weathered coal of 50% or more humic acid content or lignite, prepares
At humic acid original powder；
1.2 acidifications: by humic acid original powder, phosphoric acid solution through being dosed in the reaction kettle of sealing, in the case where being sufficiently stirred
2-3h are reacted, reaction temperature is controlled at 80-90 DEG C, completes the acidification of humic acid, makes to combine closely with calcium, magnesium, iron
Humic acid is converted to free humic acid, and calcium, magnesium, iron are transformed into the middle microelement that crop can be absorbed and utilized, and realizes
The activity of humic acid is improved by acidification；
1.3 ammoniated treatments: the material of ammonium hydroxide and above-mentioned steps (1.2) preparation through measuring is added in agitator tank, is uniformly stirred
Enter the dry ammonification of drying ammonification machine after mixing 7-9min, drying ammonification temperature control dries the ammonification time 1-at 45-55 DEG C
2h, the characteristic decomposed using ammonium hydroxide heat, makes the ammonia decomposited and free humic acid is combined into fulvo acid ammonium, and by object
Expect water content control 2% hereinafter, realizing the activity for further increasing humic acid by ammonification.Dry ammonification during this
Temperature and time is especially important, if temperature height and overlong time will cause ammonia loss, reduces ammonification effect；If temperature it is low and
It is insufficient that time passes short reaction, and ammonification effect is equally not achieved；
1.4 stacking ammonifications and biological treatment: uniformly by the material prepared by step 1.3 and the blending of activation microbial inoculum, and width is piled

(3) after being granulated, material enters drying machine, and the control of drying machine inlet temperature is at 110-125 DEG C, drying time 30-35
min；
(4) screening of bulky grain heat, sieve diameter 4.5mm are carried out after drying, the bulky grain after screening returns to rotary drum after crushing and makes
Grain machine；
(5) other materials after sieving enter cooler, cooling time 25-30 min；It is sieved after cooling through dusting cover, sieve diameter
Between 2.0-2.5mm, the granular material after dusting cover returns to rotary drum granulator, and qualified product enters packing machine, handles by anti-caking
After pack.

In enclosing, the reaction effect of phosphoric acid and humic acid is best, and the acidification of humic acid is realized using phosphoric acid, compared with using other acid, i.e.,
It realizes the acidification of humic acid and increases the content of product P elements.
Between the mass percent concentration 12%-15% of the ammonium hydroxide, by a large amount of comparative test, this concentration range
Interior, the reaction effect of ammonium hydroxide and humic acid is best, and concentration is too low, and the diffusion velocity of ammonia is slow, and reaction effect, concentration mistake is not achieved
Height, moisture is opposite to be reduced, and ammonium hydroxide infiltration is obstructed, and increases the volatilization loss of ammonia.
The activation microbial inoculum is the combination of one or both of bacillus and lactic acid bacteria, can be degraded corruption using microbial inoculum
Phytic acid macromolecular is small molecule, realizes the bioactivity processing of humic acid.
The plant growth regulator is compound sodium nitrophenolate, and additional amount determines that compound sodium nitrophenolate is 1997 according to Different Crop
Through American National, Environmental Protection Agency ratifies, into the unique artificial synthesized plant growth regulator of U.S.'s Green Foodstuff Project, in plant
The entire lifetime can be used, and having improves crop quality, increase absorption of the root to nutrient, have enhancing crop anti-true
Fungus diseases, bacteriosis, the ability of virus disease.
Product total nutrient Han Liang≤45%, total humic acid Han Liang≤3% activate humic acid Han Liang≤2%, fully meet
The professional standard of humic acid fertilizer.
High-activity humic acid ecology compound fertilizer of the invention and preparation method thereof has the following advantages compared with prior art:
1, by being acidified to humic acid, ammonification and biological treatment, improve the quantity of humic acid activity functional group, improve and use
Effect, and the calcium of slightly solubility, magnesium, iron in humic acid are converted to crop, the calcium, magnesium, iron utilized can be absorbed.
