Description
Technical field
The present invention relates to a kind of anti hardening agents, anti-compaction fertilizer and preparation method thereof.
Background technique
The Integration of Water into Fertilizer is will to irrigate the new agricultural technology to combine together with fertilising, is to irrigate and apply fertilizer to organically combine
Best way.It is calculated according to 900,000,000 mu of irrigated areas of China, water-fertilizer integral application percentage only has 2.87% at present, therefore sends out
Exhibition has a extensive future.It is very universal using one body technique of liquid manure in the agriculture developed country such as Israel, U.S., mainly select liquid
Body fertilizer or rapidly dissolvable powdery multi-element fertilizer.But liquid fertilizer needs the ducts to extend in all direction, and needs
Long term distance transport, in contrast, the flexible rapidly dissolvable powdery multi-element fertilizer of traffic condition just more have obvious
Advantage.
However, being the nitro-compound fertilizer of raw material with potassium sulfate, phosphorus ammonium, ammonium nitrate etc., hydrophily is big, in storage and transport all
There may be agglomerations.Caused by because of the hydrophily of this moisture absorption or agglomeration system by fertilizer oneself, the production of this phenomenon is entirely prevented
Life is difficult.
In the past, in order to eliminate the primary of agglomeration on condition that preventing the moisture absorption, the method for use is the chemistry fertilizer that hygroscopicity is low
Material is blended into bibulous fertilizer, and mixed fertilizer or chemical conversion fertilizer is made, perhaps powdered fertilizer is granulated or handle
Non-hygroscopic powdery stable material (such as diatomite, kaolin, talcum etc) is adhered to granulated fertilizer surface or handle
No matter packing container reform is also impossible to entirely prevent the moisture absorption, agglomeration using what kind of method at completely moisture-proof container.
