Abstract
The method that the present invention relates to a kind of mechanical force and chemical preparation release/controlled release coated carbamide containing trace element.With tannic acid as raw material, with metal ion as chelating agent, with carbamide as substrate, mechanical force and chemical one-step method is used to be prepared for the coated carbamide formed with tannic acid with complexing of metal ion.Slow/controlled release purpose is played in the release of carbamide by complex film, and it can be provided growth necessary trace element in plant growing period by chelating agent metal ion.
Description
Technical field
The method that the present invention relates to the slow/controlled release coated carbamide containing trace element prepared by a kind of mechanical force and chemical.Should
Fertilizer has pH controlled release row, and can provide the trace element needed for plant growing.
Background technology
In plant growing process, the use of fertilizer can be the nutrient needed for it provides thus improve and make produce
Amount.But common fertilizer is easy to run off effectively not utilized by plant in soil with water body, a large amount of of fertilizer use also simultaneously
Cause the waste of fertilizer and easily make soil and body eutrophication cause environmental pollution.Therefore, how to realize in plant growing
While Shi Weiqi provides necessary nutrient, moreover it is possible to it is the most necessary for effectively reducing or eliminate the pollution to soil and water body
's.Slow/controlled release technology is the conventional means solving this problem, in contrast to common fertilizer, and slowly/controlled releasing fertilizer has a lot excellent
Point, such as, can regulate fertilizer rate of release；Reduce fertilizer loss；Nutrient and minimizing needed for providing plant growing are executed
Fertile number of times etc..Using various material to form the coated fertilizer prepared by clad at fertilizer surface is a kind of important and operating procedure
Simple slow release fertilizer.
In agricultural, carbamide is a kind of conventional fertilizer providing nitrogen source to plant.Coated carbamide the most more typically is sulfur
Coated carbamide, but, the release of N element can only be played slow releasing function and without controlled release properties by this coated carbamide, and used
Wall material is sulfur, easily causes environmental pollution；Additionally, when preparing coated carbamide, owing to carbamide can be dissolved in water and some routines
In solvent, and in dry run, the crystallization of carbamide is that acicular crystal easily punctures coated fertilizer, it is impossible to carbamide is played slow-releasing
Energy.Therefore, it is inconvenient for preparing coated carbamide by common solwution method.Mechanical force and chemical is the course of reaction of nothing/few solvent,
And operating process is simple, environmental friendliness, prepares coated carbamide for us and provide important approach under condition of no solvent.Tannin
Acid is the polyphenol compound extracted from plant, can form complex film, and plant institute with Determination of multiple metal elements complexation
The most of trace element needed can form ligand complex with tannic acid, is easily formed peplos wall material, and tannic acid is cheap, easily simultaneously
?.Hence with the complexation of tannic acid Yu metal ion, prepare coated carbamide material source by mechanical force and chemical extensive, cost
Relatively low, there is wide profit margin and long-range market prospect.
Summary of the invention
For being difficult to prepare preferable coated carbamide in the solution, realize carrying of trace element in growing process simultaneously
Confession, based on Coordinative Chemistry, in conjunction with control release technic, by mechanical force and chemical, one-step method be prepared for containing trace element slow/
Controlled release coated carbamide；Transmission electron microscope shows prepared by the success of this coated carbamide；Its release dynamics shows carbamide and trace unit
Element has slow/controlled release performance.The technical solution adopted in the present invention comprises the following steps:
By 3g carbamide, 0.5g tannic acid and different metal-ion ligand (0.08g FeCl3·6H2O, 0.05g
CuCl2·2H2O or 0.19g ZnSO4·7H2O) add in ball milling instrument, ball milling instrument parameter, such as ball milling instrument rotating speed are set
(100r/min, 200r/min, 300r/min, 400r/min), automatic reaction time (10min, 20min, 30min).It is prepared into
To having the coated carbamide of slow/controlled release, this coated carbamide contain plant needed for trace element and there is pH slow-releasing.
Accompanying drawing explanation
The slow/controlled release coated carbamide prepared by mechanical force and chemical, one-step method is utilized by transmission electron microscope observing.From figure
Can be seen that the thin film layer thickness on prepared coated carbamide surface is about about 20nm.Accompanying drawing 1A is carbamide, and B is prepared
The transmission electron microscope picture of coated carbamide.
Detailed description of the invention
Below in conjunction with embodiment, the present invention will be further described, but present disclosure is not limited only in embodiment involved
And content.
Embodiment 1 is by 3g carbamide, 0.5g tannic acid, 0.08g FeCl3·6H2O(0.05g CuCl2·2H2O or 0.19g
ZnSO4·7H2O) during powder adds ball milling instrument, arranging ball milling instrument parameter, ball milling instrument rotating speed is 300r/min, the automatic reaction time
For 30min.Prepare the coated carbamide with slow/controlled release, and this coated carbamide has pH controlled capability.
Claims (2)
1. the method that the present invention relates to a kind of mechanical force and chemical preparation slow/controlled release coated carbamide containing trace element, its feature exists
