Abstract
The invention discloses a water-retaining sustained release agent for a fertilizer and a preparation method thereof. The agent is prepared by mixing refined bentonite, dicyandiamide (DCD), DA-6, agricultural rare earth, magnesium sulfate, zinc sulfate, manganese sulfate, borax and ammonium molybdate according to proportion, drying and grinding the mixture to be between 190 and 210 meshes, metering and packaging the mixture. The agent is applied after being directly mixed with a chemical fertilizer according to the proportion, can increase the utilization ratio of nitrogen by 30 percent, the utilization ratio of phosphorus by 20 percent and the utilization ratio of potassium by 25 percent and plays an important role in improving the water-retaining and drought-resisting functions of soil. The agent has the advantages of reducing the application dose of a nitrogen fertilizer by 50 percent, reducing the application dose of a compound fertilizer by 30 percent, enhancing the drought resistance capacity of crops by 50 percent in drought seasons, saving fertilizer cost, reducing drought loss, lowering cost and increasing yield for peasants, saving national energy, protecting agro-ecological environment and promoting agricultural sustainable development.
Description
Technical field
The present invention relates to a kind of fertilizer sustained release drug, specifically a kind of water-retaining sustained release agent for fertilizer.
Background technology
Commercially available fertilizer sustained release drug is actual to be a kind of nitrogen fertilizer slow releasing agent, is that several high molecular polymer manufacturings form, and cost is higher, and the peasant is difficult to accept, and might cause secondary environmental pollution in various degree, and it is relatively large that difficulty is used in marketing.
Summary of the invention
The purpose of this invention is to provide a kind of " water-retaining sustained release agent for fertilizer " that meets China's ecological, environmental protective requirement.The peasant uses after directly this product and chemical fertilizer being mixed in proportion, can improve 30 percentage points of nitrogen utilization efficiencies, improve 20 percentage points of P use efficiencies, improve 25 percentage points of potassium utilization rates, its prior effect is exactly to improve soil water-retaining drought resisting function.Use product of the present invention can reduce nitrogen fertilizer amount 50%, reduce composite fertilizer's consumption 30%, can improve farm crop drought-resistant ability 50% at arid season, save fertilizer cost, alleviate the drought loss, for peasant's abridged edition increases income.
The objective of the invention is to realize by following scheme:
A kind of water-retaining sustained release agent for fertilizer is characterized in that: the weight part proportioning of its constitutive material is:
Refining wilkinite 823-843
Two cyanogen ammonium DCD 20-40
An Fresh fat DA-6 0.5-1
Agricultural rare-earth 0-10
Sal epsom 0-100
Zinc sulfate 0-10
Manganous sulfate 5-5.5
Borax 0-10
Ammonium molybdate 0-1.
Refining wilkinite of the present invention is commercial, and refining wilkinite is the strong natural mineral of a kind of viscosity, and water-retentivity is stronger, and the 500-1000 that can absorb water doubly; DCD is the English name of the two cyanogen ammoniums of effect-elongating agent for nitrogen fertilizer; DA-6 is the English name of plant-growth regulator An Fresh fat.
Described water-retaining sustained release agent for fertilizer is characterized in that: the weight proportion of its constitutive material is one of following prescription:
Prescription 1:
Refining wilkinite 823
DCD 40
DA-6 0.5
Agricultural rare-earth 10
Sal epsom 100
Zinc sulfate 10
Manganous sulfate 5
Borax 10
Ammonium molybdate 1;
Prescription 2:
Refining wilkinite 843
DCD 20
DA-6 0.5
Agricultural rare-earth 10
Sal epsom 100
Zinc sulfate 10
Manganous sulfate 5.5
Borax 10
Ammonium molybdate 1.
The preparation method of described water-retaining sustained release agent for fertilizer is characterized in that may further comprise the steps:
(1) by the refining wilkinite of prescription requirement difference weighing, DCD, DA-6, agricultural rare-earth, sal epsom, zinc sulfate, manganous sulfate, borax, ammonium molybdate;
(2) with load weighted each constitutive material mixing and stirring, combine together;
(3) raw material drying, the mill Fine that mixes formed to 190-220 order, metering packing.
Compare with prior art, product of the present invention is to formulate two kinds of different ingredients to adapt to the different differences of two kinds of fertilizer for two kinds of application processes of nitrogenous fertilizer and composite fertilizer, alleviates environmental pollution, for peasant's abridged edition increases income.The fertilizer that adopts preparation method of the present invention to make, effective constituent is more perfect, and safer stable, vast farmers preferably uses; Product of the present invention does not add any hormone and high molecular polymer, and is nontoxic, harmless, pollution-free, also has the function of removing pesticide residue and soil disease, has simultaneously that the farm crop of enhancing are cold-resistant, a drought resisting, the anti-several functions such as saline and alkaline, pest-resistant.
Description of drawings
Accompanying drawing is process flow sheet of the present invention.
Specific embodiment
Example 1:
A kind of water-retaining sustained release agent for fertilizer, the weight proportion that it is characterized in that its raw material are one of following:
Refining wilkinite 823
DCD 40
DA-6 0.5
Agricultural rare-earth 10
Sal epsom 100
Zinc sulfate 10
Manganous sulfate 5
Borax 10
Ammonium molybdate 1,
Concrete preparation method and using method are as follows:
To make with extra care wilkinite, DCD, DA-6, agricultural rare-earth, sal epsom, zinc sulfate, manganous sulfate, borax, ammonium molybdate measure respectively, mix combine together, dry, mill Fine 200 orders, metering packing form.(together lower).Make " a kind of water-retaining sustained release agent for fertilizer " by above-mentioned prescription and preparation method, it is the prescription of formulating for the characteristics of nitrogenous fertilizer, per 20 kilograms of nitrogenous fertilizer add water 0.5% and get and can use after 1 kilogram of this product mixes, its utilization rate of nitrogen fertilizer improves 30%, reduce consumption 50%, alleviate environmental pollution, for peasant's abridged edition increases income.
Example 2:
A kind of water-retaining sustained release agent for fertilizer, the weight proportion that it is characterized in that its raw material are one of following:
Refining wilkinite 843
DCD 20
DA-6 0.5
Agricultural rare-earth 10
Sal epsom 100
Zinc sulfate 10
Manganous sulfate 5.5
Borax 10
Ammonium molybdate 1.
Making " a kind of water-retaining sustained release agent for fertilizer " by above-mentioned prescription and preparation method, is for the characteristics of composite fertilizer and the prescription of formulating, and per 25 kilograms of composite fertilizers add water 0.5% gets and can use after 1 kilogram of this product mixes, and can reduce by 30% fertilizer amount.Its preserve moisture and fertility ability is strong, reaches speed, slow, long triple effect unification, alleviates environmental pollution, for peasant's abridged edition increases income.
