Description
Technical field
The present invention relates to a kind of slow long-acting compound fertilizer of containing nitrogenous fertilizers synergist and preparation method thereof, belongs to complex fertilizer
Technical field.
Background technology
Nitrogenous fertilizer is maximum, the most widely used chemical fertilizer of the current volume of production of China, but is applied to the nitrogenous fertilizer in farmland, due to nitrifying,
The effects such as leaching, anti-digestion, lose extremely serious, its utilization rate typically only 30-50%.Therefore, how research improves nitrogen
Chemical fertilizer utilization ratio, is the important subject of nearly more than ten years in commercial production and agricultural production.The main solution for adopting at present
Approach is had Composite, concentration liquefaction, granulating, ball fertilizer deep placement, nitrogenous fertilizer slow, improvement fertilizer practice and is pressed down using denitrification
Preparation etc..
Nitrite bacteria in soil can be ammonium nitrogen rapid oxidation into nitrite nitrogen, and then nitrobacteria is again by Asia
Nitric nitrogen is oxidized to nitrate nitrogen, Nitrification of this process in soil.Various nitrogens are changed into after nitre state from ammonium state, be difficult by
Soil colloid adsorbs, it is easy to be rinsed leaching loss.Nitrogen loss caused by Nitrification, in dry crop or paddy field all
It is than major.The Nitrification of soil, this medicine is suppressed just to be called nitrification inhibitor using certain chemicals.From
Nitrogen loss is prevented, is said in the sense that strengthening fertilizer efficiency actual effect, it is generally called for nitrogen fertilizer potentiating agent in China.
External the fifties begin to the research of nitrogen fertilizer potentiating agent, and The Dow Chemical Co. (US) 2030 Dow Center, Abbott Road, Midland, Michigan 48640, develops CP nineteen sixties, thereafter
Japan develops the research work that AM, s-triazine, Britain, the Soviet Union, West Germany and India etc. have also carried out this respect again.China be
The late sixties just start, but make fast progress, and have developed 30 multiple compounds during the decade, but are still deeply grinding before more number
Study carefully, progressively expand application test kind few in number, or even some originals identify pass through, the kind of scale up test, also not
A large amount of productions can be carried out and promote supply.
Mostly the complex fertilizer for being used at present is nitrogenous fertilizer, phosphate fertilizer, potash fertilizer composition, wherein nitrogenous fertilizer mostly carbamide, carbamide ammonium nitrate
Solution, etc., but the fertilizer effectiveness phase short (40-60d), utilization rate low (40% or so), so when base manure is made with compound fertilizer special,
Later stage is in order to meet demand of the crop to nutrient, in addition it is also necessary to Nitrogen Top Dressing, increased the cost of human and material resources.
The production of stable fertilizer and application are being continuously increased every year, and the research of nitrogen fertilizer potentiating agent and application are stable for the world
Property fertilizer production provide scientific basis.Eye on the Future, from raising fertilizer utilization efficiency, increase economic benefit and environmental conservation
From the aspect of, the potentiality of the stable fertilizer of applied nitrogen synergist and market are huge.The utilization of nitrogen fertilizer potentiating agent,
Cause the concern of various countries distributor and vast farmerses.Expert always works on the screening of nitrogen fertilizer potentiating agent and tries out both at home and abroad for many years
Experiment, but individually the action effect of a certain kind nitrogen fertilizer potentiating agent is all less desirable, and existing procucts are yet deposited in the application
In many problems.
Content of the invention
It is an object of the invention to provide a kind of slow long-acting compound fertilizer of containing nitrogenous fertilizers synergist, its nutrient content height, delay
Release long-acting, persistently, early stage is not lost in fertility, and the later stage does not take off fertilizer, and economical and efficient is directly interior by nitrogen fertilizer potentiating agent by high-pressure spraying
Be embedded in nitrogenous fertilizer or nitrogen potash fertilizer mixed material, by soil nitrite bacteria activity effective suppression, reduce ammonium nitrogen to
The conversion of nitrate nitrogen, so as to reduce the nitrogen nutrient loss that leaching is caused, reaches nutrient and slowly discharges, supply of long duration, supports crop
Divide and absorb, improve fertilizer utilization efficiency.
It is a further object of the present invention to provide the preparation method of the slow long-acting compound fertilizer of the containing nitrogenous fertilizers synergist.
For achieving the above object, the present invention adopts following technical proposals：
A kind of slow long-acting compound fertilizer of containing nitrogenous fertilizers synergist, is made up of the raw material of following weight portion：
Nitrogenous fertilizer 5-30 parts, phosphate fertilizer 5-30 parts, potash fertilizer 5-30 parts, zinc fertilizer 0.1-10 parts, boron fertilizer 0.1-5 parts, nitrogen fertilizer potentiating agent
0.1-1 parts, coloring agent 0.01-0.05 parts；
The mixture of one or both of the nitrogenous fertilizer in ammonium sulfate or carbamide；
The mixture of one or both of the phosphate fertilizer in MAP or Diammonium phosphate (DAP)；
The mixture of one or both of the potash fertilizer in potassium sulfate or potassium chloride；
The zinc fertilizer is selected from zinc sulfate monohydrate or zinc sulphate heptahydrate；
The boron fertilizer is selected from borax anhydrouss or borax decahydrate；
The nitrogen fertilizer potentiating agent is N-serve, and dosage form is micro-capsule suspension.
The coloring agent is the indigo color lake of Beijing Orient Kai Er production.
Preferably, the slow long-acting compound fertilizer of the containing nitrogenous fertilizers synergist, is made up of the raw material of following weight portion：
Nitrogenous fertilizer 20-30 parts, phosphate fertilizer 15-30 parts, potash fertilizer 15-30 parts, zinc fertilizer 0.1-5 parts, boron fertilizer 0.1-5 parts, nitrogenous fertilizer potentiation

In nitrogenous fertilizer, it is ensured that the interpolation of nitrogen fertilizer potentiating agent is uniform, reduces the number of dropouts of nitrogen fertilizer potentiating agent, extends effective week of fertilizer
Phase, had good sustained release effect.
(3) as the nitrogen fertilizer potentiating agent used by the present invention is micro-capsule suspension, pressure too small synergist during high-pressure spraying
Cannot spray, pressure is excessive be easily caused spray uneven；Temperature is too high for spray, overlong time, nitrogen fertilizer potentiating agent can because high temperature,
Sudden and violent leakage in atmosphere overlong time and cause synergist to fail, spray time is unsuitable long, therefore high-pressure spraying process conditions
Selection is particularly critical to spraying effect, and using the high-pressure spraying technique of the present invention, nitrogen fertilizer potentiating agent can be realized uniform embedded
In nitrogenous fertilizer or nitrogenous fertilizer, the mixed fertilizer of potash fertilizer.
