Abstract
A kind of preparation method of multi-nutrient element liquid fertilizer, it is characterized by: containing in the liquid fertilizer: humic acid 4~16%, available nitrogen 5~14%, potassium dihydrogen phosphate 1~20.0%, potassium nitrate 1~20.0%, 0.1~10.O% of calcium nitrate, magnesium sulfate 0.1~5.0%, ferrous sulfate 0.1~5.0%, zinc sulfate 0.1~5.0%.The present invention: the humic acid with coordinate plant growth and certain restraining and sterilizing bacteria and anthelminthic effect is as matrix, cooperate the various nutrients being added, the effect of restraining and sterilizing bacteria and coordinate plant growth is substantially increased, the waste when liquid fertilizer uses is greatly reduced.
Description
Technical field
The present invention relates to a kind of preparation methods of liquid furtilizer containing humic acid multi nutritive element.
Background technique
Humic acid is substance, be not pure material, it be a kind of macromolecular, organic monoacid mixture, be that nature is dynamic
The residuum of plant, the residuum of mainly plant.By the decomposition and conversion of microorganism and the earth, physics, chemistry it is a series of
Process is gradually formed and is accumulated, natural, unformed, chemically stable organic high molecular compound.Molecular weight is big
It is small different, from several hundred to tens of thousands of etc..Usually there are three fractions；That is fulvic acid, hymatomalenic acid, pyrotomalenic acid.Fulvic acid
Minimum (several hundred to thousands of), hymatomalenic acid (thousands of to the tens of thousands of) pyrotomalenic acid of molecular weight (more than tens of thousands of).Humic acid molecule contains
There are phenyl ring, condensed ring and various heterocycles (such as pyrroles, furans, indoles), is connected between each aromatic ring by bridged bond, there are various work on aromatic ring
Sexual function group.Such as carboxyl, phenolic hydroxyl group, methoxyl group, alcoholic extract hydroxyl group, carbonyl, quinonyl.Since humic acid has extremely complex molecule
Structure, it has colloidal nature, there is very strong adsorption capacity, complexing, sequestering power, ion-exchange capacity.So humic acid is used
Make agricultural fertilizer, there is improvement soil；Salt-soda soil can be improved, soil salinity characters are prevented and treated, sandy land is improved, prevents and controls desertification, is improved
The effect of white slurry and red soil.
Summary of the invention
To overcome problems of the prior art, the present invention is intended to provide it is a kind of can supply it is complete needed for plant growth
Flour nutrition, coordinate plant growth development, bactericidal and the liquid furtilizer containing humic acid multi nutritive element to disinfest preparation side
Method.
The technical scheme is that be accomplished by the following way: a kind of preparation side of multi-nutrient element liquid fertilizer
Method, it is characterised in that: contain in the liquid fertilizer: humic acid 4~16%, available nitrogen 5~14%, potassium dihydrogen phosphate 1~
20.0%, potassium nitrate 1~20.0%, 0. 1~10.O% of calcium nitrate, magnesium sulfate 0.1~5.0%, ferrous sulfate 0. 1~5.0%, sulphur
Sour zinc 0. 1~5.0%, comprising the following steps: it is characterized by:
1), extract humic acid: selection hard broad-leaved xylem is cut into 40 ~ 80mm wide, the square woods section of 500 ~ 600mm long, warp
Microwave dehydration, content in merging flue gas charing pyrolysis oven, are carried out anhydrous air oxygen supply, are carried out micro- between 4% ~ 18% in furnace
Oxygen burning, in-furnace temperature are controlled 1500C~3500Between C, it is pyrolyzed the volatile matter of evolution, is divided through the adjustable device that is isolated from the recombinant
From the volatile matter after separation is re-fed into cooler and carries out the cooling condensable liquid of collection, i.e. wood vinegar, and cooling temperature is 200C~
800Between C, there is no pH value detection mouth in liquid collecting tube, when liquid pH value reaches 4 ~ 6, terminates and collect；
2), aggregation separation: wood vinegar is placed in container, and the polyvinylpyrrolidone of investment 0.5 ~ 5% stirs 10min ~ 30min,
After standing 60 ~ 90 days, supernatant liquid filtering is taken；
3), adsorbing separation: by 60 mesh ~ 80 mesh blanket activated carbon fibre of investment 1 ~ 15% in filtered fluid, 1 ~ 30min is stirred, is stood
It is filtered after for 24 hours ~ 36h；
4), finished product filters: 1~20.O% of urea, potassium dihydrogen phosphate 1~20.0%, nitric acid being added in the wood vinegar finished by standing
Potassium 1~20.0%, 0.1~10.O% of calcium nitrate, magnesium sulfate 0.1~5.0%, ferrous sulfate 0. 1~5.0%, zinc sulfate 0. 1~
5.0%, it is filtered with subtle filter paper, finally obtains the harmless wood vinegar liquid fertilizer of efficient.
The invention has the following advantages that the humic acid with coordinate plant growth and certain restraining and sterilizing bacteria and anthelminthic effect is made
For matrix, cooperates the various nutrients of addition, the effect of restraining and sterilizing bacteria and coordinate plant growth is substantially increased, in liquid fertilizer
During preparation, humic acid film technique has been incorporated, has greatly reduced the waste when liquid fertilizer uses.Since raw material is rich
Rich, content height, process equipment is simple, low energy consumption, high, at low cost, the easy implementation of fertilizer efficiency.
Specific embodiment
A kind of multi-nutrient element liquid fertilizer contains in the liquid fertilizer: humic acid 4~16%, available nitrogen 5~14%,
Potassium dihydrogen phosphate 1~20.0%, potassium nitrate 1~20.0%, 0. 1~10.O% of calcium nitrate, magnesium sulfate 0.1~5.0%, ferrous sulfate
0. 1~5.0%, zinc sulfate 0. 1~5.0%.
Preparation method has following steps:
