Abstract
The invention discloses a bulk blended fertilizer, which is formed by mixing compound fertilizer granular materials and other granular materials according to a ratio, wherein all granular materials are spherical and uniform in grain size. Compared with the current bulk blended fertilizer, the bulk blended fertilizer has the advantages that: nitrogen, phosphorus and potassium nutrients are uniform; grain size is uniform and specific weights of grains are approximate; and the phenomenon that the segregation of the product influences the use is avoided.
Description
Technical field
The present invention relates to agricultural bulk blended fertilizer, particularly relate to a kind of novel bulk blended fertilizer and manufacture method thereof.
Background technology
In agriculture production, be extensive use of various fertilizer, mainly be for example urea, sulphur ammonium, Repone K, coarse whiting etc. and contain the polyelement composite fertilizer of nitrogen, phosphorus, potassium and other nutritive element of chemical fertilizer of simple substance, these fertilizer all are the granulated fertilizers of making by certain technology and equipment.They can provide various nutrients to the growth of plant.Also made contribution for the increasing both production and income of peasant household.
The bulk blended fertilizer that uses in the agriculture production at present mainly is the product that is formed by big grain urea, phosphorus ammonium and the blending of big grain potash fertilizer.Because having the granularity shape, inconsistent (big grain potash fertilizer is the extruding granulating, the flat bulk of granularity non-sphere), the particle diameter of granularity is inconsistent, proportion between every kind of particle differs greatly, cause the segregation of Bulk Blending Fertilizer product serious, plant absorbing nutrient inequality when gently then causing peasant household to use, heavy then cause fertilizer damage to cause the crops underproduction.
Summary of the invention
The present invention is intended to overcome the defective that exists in the above-mentioned technology, a kind of bulk blended fertilizer and manufacture method thereof are provided, it is raw material that this bulk blended fertilizer adopts granular composite fertilizer and other material granule, therefore product design is different fully with former bulk blended fertilizer manufacture method, it all is the uniform product of positive spherical granules, and production technique is simple, and reduces the energy consumption of production process, and realizes three-waste free discharge.
The principle of the invention is, the spherical nitrogen phosphorus of existing particle diameter 2.0～3.6mm or nitrogen potassium or phosphorus potassium or nitrogen-phosphorus-potassium compound fertilizer and other particulate material are carried out blending, because what adopt is evengranular spherical granules composite fertilizer, and approaching substantially between the compound fertilizer granules with other particulate proportion, the therefore existence of having stopped the product segregation phenomena.
Technical scheme of the present invention is as follows:
A kind of bulk blended fertilizer, it is to be mixed in proportion by compound fertilizer granules raw material and other particulate material to form, all particulate materials all are positive ball-type and epigranular.
As a kind of improvement of bulk blended fertilizer of the present invention, described compound fertilizer granules and other feed particles particle diameter are 2.0～3.6mm, and proportion (Bulk Specific Gravity) is 800～1000kg/m
3
As a kind of improvement of bulk blended fertilizer of the present invention, described compound fertilizer granules raw material accounts for 80～99.8%, other particulate material 0.2～20%; Preferred compound fertilizer granules raw material accounts for 85～95%, other particulate material 5～15%.
As a kind of improvement of bulk blended fertilizer of the present invention, described compound fertilizer granules raw material is two or more the mixture in compound nitrogen phosphate fertilizer or nitrogen-potassium compound fertilizer or phosphorus potassium complex fertilizer or nitrogen-phosphorus-potassium compound fertilizer or organic fertilizer or the organic and inorganic fertilizer.
As a kind of improvement of bulk blended fertilizer of the present invention, described other particulate material be in, trace element, the mixture of one or more in fertilizer synergist, the fertilizer slow-release formulation.
As a kind of improvement of bulk blended fertilizer of the present invention, described every kind of particulate diameter is all at 2.0～3.6mm.
As a kind of improvement of bulk blended fertilizer of the present invention, described particle can be made various color grains.
A kind of method of making above-mentioned bulk blended fertilizer, it is the employed compound fertilizer granules raw material of production bulk blended fertilizer and other particulate material to be joined in proportion mix the back metering packing in the mixing tank.
The invention has the advantages that:
The same nitrogen phosphorus of a, this product and compound manure potassium nutrient is even;
B, this product particle shape are positive ball-type and epigranular;
C, this product variable grain proportion are close, the situation that product segregation influence is used can not occur;
D, particle surface be smooth, do not lump, and has the higher market competitiveness.
