Used according to humic acid fertilizer provided by the invention and have the anticaking agent of fertilizer synergistic function, main innovative point
It is：First, stalk ashes are introduced, ashes main chemical is potassium carbonate, potassium sulfate, the mixture of potassium chloride, and these are mixed
Thing is all soluble potassium salt, on the one hand, sylvite molecule energy bound fraction free water is changed into the crystallization water, reduce fertilizer agglomeration because
Element, on the other hand, potassium element needed for crops can be directly provided, increase fertilizer efficiency is reached while fertilizer agglomeration is prevented
Effect；Second, the stearic acid commonly used using unrighted acid fertilizer for replacing chemical anticaking agent industry makees surfactant, thus matches somebody with somebody
The powder anticaking agent gone out improves adsorptivity of the agglomeration agent in fertilizer surface, and reduces dust in use and float；The
Three, do surfactant, the conventional primary octadecylamine of fertilizer for replacing chemical anticaking agent industry, carbon ten using the fatty alcohol of carbon ten six-ten eight
The addition of six-ten eight fatty alcohols can suppress urea components in fertilizer, and because of temperature Change, " dissolution-crystallization " is tied caused by repeatedly
Block problem, because humic acid fertilizer generally contains higher moisture than pure chemistry fertilizer, have with fatty alcohol ratio fatty amine preferably anti-
Tie effect；4th, agglomeration preventing performance can be further improved by introducing the crystalline flake graphite with lubrication or micro crystal graphite, is had
Body, crystalline flake graphite or micro crystal graphite be adsorbed onto fertiliser granulates surface and can make mutually to slide between fertiliser granulates, fertilizer stack by
Degree of agglomeration, while both graphite and humic acid fertilizer solid colour are reduced in the case of pressure, will not be to humic acid fertilizer certainly
Body color is impacted, and both graphite have gloss, and fertiliser granulates can be made attractive in appearance；5th, by introducing polyacrylic acid
Potassium solves the moisture problem on fertiliser granulates top layer, and polyacrylic acid potassium is high water absorption material in itself, can not only solve moisture problem, also
With the quick characteristic for doubling expansion of water suction, add the physical isolation between fertiliser granulates, the material absorb water in soil and
The process for releasing water serves the effect of fertilizer slow release, and the material that the material is stayed in soil after with the passing of time degrading in addition is finally to be solvable

Compounded using both different surfactants, synergistic action effect is more preferable.Specifically, one side unrighted acid
And the addition of the fatty alcohol of carbon ten six-ten eight can suppress in fertilizer urea components because temperature Change repeatedly " dissolution-crystallization " so as to
Caused agglomeration problems, on the other hand, carboxylic acid, the hydroxyl polar group of the fatty alcohol of carbon ten six-ten eight of monounsaturated fatty acid molecule
Group, salt group can be formed with the metal ion in fertilizer, there is stronger activity, further increase anticaking agent in fertilizer
The adsorptivity on surface.The surfactant of conventional neopelex, lauryl sodium sulfate etc, can only be water-soluble
Activity can just be shown in liquid, be installed in powdered anti-caking agent, without any preventing blocking effect, and fertilizer wants anti-caking to avoid
Water, therefore no matter match somebody with somebody pulvis or liquid anti-caking agent, neopelex, lauryl sodium sulfate etc surface and live
Property agent has been no longer used.Further, wherein the content of unrighted acid is 3%-5%, preferably 4%；Carbon ten six-ten
The content of eight fatty alcohols is 1.5%-3%, preferably 2%.
