Abstract
A kind of sustained release fertilizer efficiency moisturizing fertilizer of the present invention belongs to agricultural fertilizer field, fertilizer layer, the filter layer being wrapped in successively in capsule core by capsule core and from the inside to the outside form, wherein capsule core is the high absorbency material after fully water suction, fertilizer layer is general chemical fertilizer, and filter layer is degradable, has chemosmotic material to soil friendly；The present invention can provide a kind of production cost is low, production efficiency is high, can have the function and effect of release and release control fertilizer and slow release fertilizer simultaneously, there is certain moisture-keeping function to upper soll layer, is suitable for a kind of sustained release fertilizer efficiency moisturizing fertilizer of the soil of arid area.
Description
Technical field
A kind of sustained release fertilizer efficiency moisturizing fertilizer of the present invention belongs to agriculture field more particularly to a kind of agricultural fertilizer.
Background technology
Some are because of reasons such as volatilization, denitrifications after fertilising for common fertilizer, and fertilizer efficiency absorbs, utilization rate is very low, and it is fixed to need
Phase constantly applies fertilizer, and to meet the growth of plant, some fertilizer then may injure crop when application because local concentration is excessively high
The adverse consequences such as seed, seedling or leaf of burning, these fertilising processes not only increase labor intensity, more add labour at
This.
Slow release fertilizer can change traditional fertilization mode, and single fertilization can be achieved in various crop, not have to top dressing, letter
Change fertilization program, makes sowing is synchronous with fertilising to carry out, thus greatly reduce rural labor intensity, raise labour productivity.It
With slow release long-acting effect, utilization rate of fertilizer can be increased substantially, can economize on resources, subtract in same origin equal production volume level
Few rate of fertilizer.
Release and release control fertilizer be with granular chemical fertilizer (nitrogen or compound nitrogen phosphate fertilizer etc.) be core, surface layer coat one layer of low aqueous solubility or micro-
The inorganic substances or organic polymer of dissolubility, such as sulphur, pitch, resin, polyethylene, paraffin, ground phosphate rock is as film forming matter,
It is gradually decomposed by Releasing nutrient by coating diffusion or coating.It is same to improve utilization rate of fertilizer, and avoid occurring due to excess
To the injury of seed or seedling caused by fertilising.
The maximum feature of super absorbent resin is its powerful water absorbing capacity, and numerous studies both domestic and external show, high water absorption
Property resin be applied to water-saving agriculture, drought-resistant water-preserving can be played, improvement soil, inhale the good actions such as fertile fertilizer conservation.It is existing to be inhaled with height
Carrier of the water-base resin as fertilizer nutrient by fertilizer nutrient element compounds or is aggregated to polymerization using chemically synthesized method
In object molecule, the moisture-retention sustained release fertilizer of chemical synthesis is made, by fertilizer and water-retaining agent composite integrated, such as Chinese patent, application
Number it is：A kind of nitrogenous super absorbent resin fertilizers and preparation method thereof containing potassium of CN200910071920.
But the above method has following defect：1, price is high, is as many as 3-4 times of common fertilizer；2, complex process, polymerization
Time long production efficiency is low, and it is raw that these cause the slow release fertilizer overwhelming majority to be served only for the high flowers of economic value, vegetables, lawn etc.
In production, being widely used for it is limited；3, height is required to soil moisture, is not suitable for drought and water-scarce area；4, only there is folk prescription
The slow release fertilizer or release and release control fertilizer in face act on.
Invention content
The purpose of the present invention is to provide a kind of production cost is low, production efficiency is high, can there is release and release control fertilizer and sustained release simultaneously
The function and effect of fertilizer have upper soll layer certain moisture-keeping function, are suitable for a kind of sustained release fertilizer efficiency moisturizing fertilizer of arid area
Material.
The object of the present invention is achieved like this：A kind of sustained release fertilizer efficiency moisturizing fertilizer includes capsule core and from the inside to the outside successively
Fertilizer layer, the filter layer being wrapped in capsule core, capsule core are the high absorbency material after fully water suction, and fertilizer layer is general chemical fertilizer；
Heretofore described high absorbency material is super absorbent resin；
Heretofore described super absorbent resin is hydrolysate, the Starch with Acrylic Acid of Starch-Acrylontirile Graft Copolymer
Salt graft copolymer, carboxymethyl cellulose, vinyl alcohol-sodium acrylate copolymer, polyacrylic acid sodium salt any one or more of
Combination, preferably polyacrylic acid sodium salt；
Heretofore described general chemical fertilizer is urea, ammonium phosphate fertilizers, composite fertilizer, Macroelement water-soluble fertilizer, again
The combination of secondary element fertilizer, bio-feritlizer, organic fertilizer any one or more of；
Heretofore described filter layer is degradable, has chemosmotic material to soil friendly, including inorganic
One or more combinations in material, biomaterial, organic material；
Heretofore described filter layer can also be with the carbonate of soil friendly or its arbitrarily combine.
The preferred calcium carbonate of heretofore described filter layer, calcium phosphate.
Due to carrying out above-mentioned technical proposal, when a kind of sustained release fertilizer efficiency moisturizing fertilizer after fully absorbing water is entered by fertilising
After plant soil, because soil is relatively dry, capsule core gradually dissolves the fertilizer of cladding thereon, has stepped through filter layer and enters crop root
Soil plays the role of slowly moist, nutrient soil.Meanwhile filter layer also can be decomposed gradually and dissolve or degrade, to extend fertilizer
Effect release；When capsule core moisture all by soil absorption after, water-absorbent material belongs to harmless resin material, and it is ventilative to play increase to soil
Property effect without destroy soil, when soil watering Irrigation, but absorb moisture play the role of soil moisturizing.The present invention need not answer
Miscellaneous polymerisation can carry out the effectiveness of fertilizer controlled and sustained release, and carry out moisturizing to the surface layer of soil, can be suitable for
The soil of arid area.
