Abstract
The present invention provides a long-acting humic acid phosphate fertilizer and a preparation method thereof. Cheap coal humic acids and general quick-acting phosphate fertilizers are used for making a long-acting phosphate fertilizer through chemical reactions under the action of accelerators and complexing agents. The method uses special chemical reactions to make an HA-P compound generated by the reactions effectively inhibit the fixation of effective phosphorus and reduce the soil fixation of the phosphorus by 16%. Under the condition that fertilizer application is the same or reduced, compared with corresponding common phosphate fertilizers, the HA-P can increase the yield by about 10%, and the utilization rate of P is increased by 10 %.
Description
Technical field:
The invention belongs to slow release fertilizer, relate in particular to a kind of preparation method of long-acting humic acid phosphate fertilizer.
Background technology:
Phosphorus (P) is one of necessary element of crop growthing development, and rationally using of phosphate fertilizer becomes the important factor of guaranteeing crop yield and improving agriculture production benefit.But because soil is to phosphorus fixation, cause crop extremely low to the utilization ratio of phosphate fertilizer, its quick-acting (water-soluble) phosphorus major part that is manured into soil in general seven days of the back changes into invalid phosphorus and also has part phosphorus to be dissolved in water body in addition, causes body eutrophication, worsens the mankind and habitable environment.Therefore, reduce phosphorus fixation and loss, improve phosphate fertilizer utilization efficiency and fertilizer efficiency, become focus and difficult point that current chemical fertilizer and agronomy circle are competitively studied.The long-acting slowization of phosphate fertilizer is the key measure that solves this difficult problem.
Studies show that in a large number that both at home and abroad coal-based humic acids (HA) is the effective fertilizer synergistic agent of a kind of cheapness, for the loss that reduces nitrogen and potassium, inhibition phosphorus fixation obvious effect is arranged, and the effect of phosphate fertilizer is especially caused people's common concern.Early fifties, Japanese scholar has found that HA has the effect of the phosphate fertilizer of inhibition fixed, Chinese scholar has also been done great deal of experimental, proves that adding various HA salt in the soil has all reduced soil to phosphorus fixation.
At present, the patent documentation and the report of relevant long-acting humic acid phosphate fertilizer preparation are a lot, mainly adopt following two kinds of methods: (1) HA or its esters and quick-acting phosphate fertilizer mixing granulation, make granulated fertilizer.Tian Sanlang herds in Japan, and (day special permission communique 49-123849) was once used nitro xanthohumic acid (NFA) and calcium superphosphate mixing granulation, thought that NFA has stoped the effect of water-soluble phosphorus and metal ion, made the phosphate fertilizer stay in grade, the fertilizer efficiency raising.15~17% ammonium humate (HA-NH was also once used in Uzbekistan (USSR 359247)
4) mix with general calcium or coarse whiting and to make granulated fertilizer.China produces HA-P's in this way.USSR (Union of Soviet Socialist Republics) (SU 139328) was once being carried out granulation behind the rotten sodium solution of spray on the general calcium powder.Japanese Patent (day special permission communique) discloses: slow-acting type HA-NP composite fertilizer is made in HA and the reaction of phosphorus ammonium heating and pressurizing, but does not see industrialized report; (2) HA-NPK and multi-element particle composite fertilizer.China and Japanese publication are crossed this type of patent in recent years, prove use the said products after, can reduce phosphorus fixation, improve utilization ratio and the crop yield of P.But the simple substance of the simple and mechanical mixed type of this class and compound fertilizer still are in extensive state so far, and technology falls behind, and effect is stable inadequately, does not also reach a standard fully economically.About HA and phosphate fertilizer chemical reaction prepare the technology of composite organic phosphate fertilizer, do not appear in the newspapers so far.
Summary of the invention:
The invention provides a kind of low cost, the preparation method of the long-acting humic acid phosphate fertilizer that effect is stable.
Long-acting humic acid phosphate fertilizer of the present invention, its main component weight percent is:
Moisture 3-5% ash content 34-63%
Humic acids content 7-54% available phosphorus content 9-25%.
The preparation of long-acting humic acid phosphate fertilizer of the present invention is carried out as follows:
(1) will be crushed to 40 order to 80 purposes and contain humic acid material coal, promotor, complexing agent, quick-acting phosphate fertilizer and mix, 50-120 ℃ of reaction 0.5-5 hour with the part by weight of water with 10-90: 0.5-10: 0.1-2: 10-90: 50-200;
(2) above-mentioned reactant through be concentrated into moisture less than 50% after, drying is made the long-acting humic acid phosphate fertilizer product.
The aforesaid humic acid material that contains is peat, brown coal, weathered coal etc., and its humic acids content will reach 40% (butt) at least, is preferably more than 60%.
Aforesaid promotor is that weight percent concentration is a kind of or its mixture of the mixture of carbon ammonium aqueous solution of ammoniacal liquor, 2-20% of 5-10% or potassium hydroxide, sodium hydroxide, ironic hydroxide.
Aforesaid complexing agent can be a kind of or its mixture of ferrous sulfate, Tai-Ace S 150, zinc sulfate, manganous sulfate.
Aforesaid quick-acting phosphate fertilizer can be calcium superphosphate, primary ammonium phosphate or Secondary ammonium phosphate.
Compare with technology is arranged mutually, the present invention has following advantage:
1. adopt low-grade coal (peat, brown coal and weathered coal) humic acids and quick-acting phosphate fertilizer to carry out the operational path of chemical reaction, its technology is simple, and is with low cost.
Since in the humic acids active oxygen-containing functional group and phosphate fertilizer effective combine and formed the HA-P mixture, make quite a few water-soluble phosphorus be converted into the molten phosphorus of Chinese holly, and increased the total available phosphorus content in the reaction product, having overcome common quick-acting phosphate fertilizer is easy to fundamentally realized long-actingization of phosphate fertilizer by soil fixing, shortcoming that phosphorus utilization is low.
3. the molten phosphorus of more Chinese holly is arranged in the product of the present invention, and owing to the molten phosphorus of Chinese holly is not easy by soil fixing, thereby therefore prolongation has greatly improved the utilization ratio of phosphate fertilizer to the time of plant phosphorus supply.
4. the present invention has also overcome the drawback of easy moisture absorption of common phosphate fertilizer and caking owing to the adding of humic acids.
5. under or the situation about reducing identical in rate of fertilizer application, HA-P is than corresponding common phosphate fertilizer volume increase about 10%, and the P utilization ratio improves 10 percentage points.
6. because the synergistic effect of humic acids, make this product also have indissoluble phosphorus in the activating soil, the physico-chemical property of improving the soil, improve crop quality, strengthen advantage such as crop anti-adversity energy.
7. product of the present invention also can be used as the main ingredient of high-concentration multi-element compound and bulk blended fertilizer except that using as long-acting phosphate fertilizer separately.
