Description
Technical field
A kind of the present invention relates to field of agricultural fertilizer, in particular it relates to non-caking nitrate-based compound fertilizer that can be entirely water-soluble
And preparation method thereof.
Background technology
Nitrate-based compound fertilizer, be a kind of contain ammonium nitrogen and nitrate nitrogen, the long-acting composite fertilizer with quick-acting combinations, micro in being rich in
Element, plant growth regulator can improve crop and various nutrients are absorbed, and improves the resistance of crop, especially suitable
Close happiness nitrate nitrogen, the industrial crops of happiness sulphur, and the optimal fertilization mode of industrial crops is drip irrigation, this is widelyd popularize with country
Water-fertilizer integral is consistent.Water-fertilizer integral has water saving, section fertilizer, saves labour, reducing energy consumption, uniform irrigation, reduces disease
The advantages of generation of insect pest, raising crop yield, but the requirement to fertilizer is stricter, typically requires water-insoluble in fertilizer
Content is less than 0.5wt%, even if but actually fertilizer water-insoluble reaches above-mentioned requirements, still there is the possibility of clogging drip irrigation water dropper,
Therefore, the fertilizer water-insoluble for drip irrigation should be required more low better.
In the high Humid Area of southern high-temperature, nitrate-based compound fertilizer is easy to caking it is necessary to take preventing block method, using tradition
Oiliness anticaking agent peplos adds the mode of face powder outside inert powder although more satisfactory preventing blocking effect can be played,
But also can increase fertilizer water insoluble matter content, product has one layer of oily mater floating after being dissolved in water, bottom also has and sinks in a large number
Form sediment, these oily floating things and precipitation can block spray drop and fill service conduit or water dropper.Therefore, in order that nitrate-based compound fertilizer is more suitable
Together in water-fertilizer integral, not only various raw materials must accomplish to be dissolved completely in water, and also necessary in the selection of anticaking agent
Using water miscible anticaking agent.But do not have the effect of traditional oil-bound distemper good using the preventing blocking effect of water-soluble anticaking agent,
In addition to formula or technologic factor, when running into hot and humid weather, fertilizer equally easily lumps.Report some prevent
Add certain special inorganic salts such as magnesium nitrate, magnesium sulfate etc. in caking method and can play good anti-caking effect in fertilizer
Really, the anti-caking mechanism of these inorganic salts is to reduce the brilliant temperature of ammonium nitrate, has hydrability simultaneously, plays crystalline phase stabilizer
With the effect of drier, more it is essential that its addition particular importance is it is necessary to just can play good anti-within the specific limits
Caking acts on.
Additionally, typically water-soluble nitrate-based compound fertilizer does raw material using Mannheim proeess potassium sulfate, this potassium sulfate pH is very low,
Fertilizer pH may be led to low, low pH not only can reduce the utilization rate of each nutrient in fertilizer it is even more important that leading to fertilizer
Material is serious to lump.And above-mentioned, sulphur can be avoided the occurrence of using the potassium sulfate that potassium chloride and ammonium sulfate double decomposition produce
Sour potassium pH is typically between 6.0-7.0, and particle is slightly thicker than Mannheim proeess potassium sulfate, can improve slip state, reduces material
Slurry temperature degree, is conducive to granulating, reduces the possibility of fertilizer agglomeration.
