Description
Technical field
The present invention relates to fertilizer and its processing technique field, more particularly to a kind of ammonium sulphate phosphate improving alkaline land soil structure
Slow-release fertilizer and preparation method thereof.
Background technology
Saline-alkali soil is the general name of solonchak and alkaline earth.Solonchak refers mainly to chloride or the higher salinization soil of sulfate,
Soil is in alkalinity, but pH value is not necessarily very high；Alkaline earth refers to carbonate containing or the phosphatic soil of weight, and pH value is higher, and soil is in
The content of organic matter of alkalinity, saline-alkali soil is few, and soil fertility is low, and physicochemical character is poor, more to the harmful anions and canons of crop, crop
It is not easy to promote seedling.
The salinization of soil is one of the global problem that current people face, and improvement, the development and utilization to salt-soda soil are
Countries in the world are paid close attention to and the focus of research.For developing country, urban land and agricultural land mutually tie up, face of ploughing
Product constantly reduce, a large amount of forests, meadow and wetland resource thus opened up wasteland for arable land, destroy original landforms and vegetation knot
Structure influences soil natural physicochemical property, accelerates the generation of salinization of soil.
Invention content
The present invention in order to solve the above technical problems, provide it is a kind of improve alkaline land soil structure ammonium sulphate phosphate slow-release fertilizer and its
Preparation method.
It is realized particular by following technical scheme：
The present invention provides a kind of ammonium sulphate phosphate slow-release fertilizer improving alkaline land soil structure, sulfur content 8%-13%.
The ammonium sulphate phosphate slow-release fertilizer of the improvement alkaline land soil structure is that liquid elemental sulphur is uniformly distributed in degree of neutralization
For in the Diammonium phosphate (DAP) of 1.3-1.4.
The present invention provides a kind of ammonium sulphate phosphate slow-release fertilizer improving alkaline land soil structure, preparation method：
1) it takes Cosan to be mixed with surfactant A, obtains modified sulfur powder, surfactant A dosage is Cosan dosage
1-4%；
2) after mixing modified sulfur powder with diatomite, with Cosan is steam heated at liquid, mixed slurry is obtained；
3) phosphoric acid is mixed with surfactant B, obtains modified phosphate, surfactant B dosage is phosphoric acid dosage 1-4%；
4) by mixed slurry be added modified phosphate in, by be pumped into tubular reactor neutralization of ammonia reaction after spray into comminutor into
Row is granulated to get ammonium sulphate phosphate slow-release fertilizer.
The Cosan, grain size≤100 μm.
The surfactant A is any one or a few mixing in tapioca, methylcellulose, konjaku powder
Object.
The surfactant B is the mixed of any one or a few in neopelex, dodecyl sodium sulfate
Close object.
The diatomite dosage is 0.8-1.1 times of Cosan dosage.
Advantageous effect：
Ammonium sulphate phosphate slow-release fertilizer of the present invention so that sulfur content is 8%-13%, reduces soil pH value and EC values, solves soil
Earth secondary salinization occurs so that soil phosphorus nutrient increases, and the present invention carries out system fertilizer so that air nitrogen use efficiency with diatomite
Increase, and slow controlled release formed to phosphor ammonium product, improve nitrogen, phosphorus element utilization rate；Diatomite has adsorptivity simultaneously, can inhale
Attached edaphon, and decomposed under microbial action so that effective element is released.
The present invention forms molten sulfur using steam treatment sulphur, avoids production hidden danger, and combines tapioca, methyl fine
The modifying function of dimension element, konjaku powder any one or a few mixture, has adjusted the hydrophilicity and hydrophobicity of sulphur, so that sulphur
Sulphur and diatomaceous combination are closer, are more evenly distributed, and contribute to the rate of release for controlling element sulphur.
The present invention is handled using any one or a few mixture in neopelex, dodecyl sodium sulfate
Phosphoric acid, and the degree of neutralization of Diammonium phosphate (DAP) is strictly controlled, the dissolubility of Diammonium phosphate (DAP) is not only increased, Diammonium phosphate (DAP) is further improved
With the dispersibility and binding performance of molten sulfur, and then avoid production hidden danger, prevent powder dust and reunite caking the phenomenon that.
The present invention uses granulated fertilizer, is conducive to element sulphur and forms slow releasing function to phosphor ammonium product, improves nitrogen, phosphorus element
Utilization rate avoids nutrient waste and soil hardening.
