Abstract
The utility model discloses a kind of large-particle long-acting slow-release nitrogen fertilizer, include urea ammonium nitrogenous fertilizer particle, it is characterized in that: described urea ammonium nitrogenous fertilizer particle is wrapped with sodium polyacrylate water conservation layer, described sodium polyacrylate water conservation layer is wrapped with attapulgite, described attapulgite is wrapped with urease inhibitor slow release layer, described urease inhibitor slow release layer is wrapped with mineral manure slow release layer, described mineral manure slow release layer is wrapped with poly aspartic acid coating layer, described poly aspartic acid coating layer is wrapped with micro-layer, described micro-layer is wrapped with diatomite anti-caking layer.The utility model reasonable in design, this fertilizer has nitrogen fertilizer slow-releasing stable performance and preservation capacity of water and fertility is strong, balanced in nutrition, meets crop uptake characters, promotes crop growth, thus improve crop yield and quality.
Description
Technical field
The utility model relates to a kind of granulated fertilizer, particularly relates to a kind of large-particle long-acting slow-release nitrogen fertilizer.
Background technology
Granular urea is that one is having under formaldehyde existent condition, forms the larger urea product of particle, compare, its smooth surface, uniform particles, prevented from caking with common urea through secondary condensation.Be characterized in: (1) dust content is low, granule strength is higher, good fluidity, can bulk shipment, and not easily broken and caking, is suitable for mechanized application; (2) surface-area is less, and after being manured into soil, dissolution rate is slightly slow, adds that Single seed weight is comparatively large, uses under can sinking to darker soil, reduce volatilization loss in paddy field; (3), because complete processing is different to the requirement of urine concentration, the Biuret Content in general granular urea product is lower, and this is favourable to crop.Although have above advantage, existing granular urea structure is simple, and its nitrogen form, slow-releasing, water retention property and nutritive ingredient can not meet crop uptake characters, are unfavorable for that Crop nutrient balance absorbs, thus reduce crop yield and quality.
Utility model content
The purpose of this utility model is the deficiency in order to make up prior art, provides a kind of large-particle long-acting slow-release nitrogen fertilizer.
The utility model is achieved through the following technical solutions:
A kind of large-particle long-acting slow-release nitrogen fertilizer, include urea granules, it is characterized in that: described urea ammonium nitrogenous fertilizer particle is wrapped with sodium polyacrylate water conservation layer, described sodium polyacrylate water conservation layer is wrapped with attapulgite, described attapulgite is wrapped with urease inhibitor slow release layer, described urease inhibitor slow release layer is wrapped with mineral manure slow release layer, described mineral manure slow release layer is wrapped with poly aspartic acid coating layer, described poly aspartic acid coating layer is wrapped with micro-layer, and described micro-layer is wrapped with diatomite anti-caking layer.
Described urease inhibitor slow release layer is formed by quinhydrones, N-NBPT, thiophosphoryl triamide, phosphoryl triamide one or its any mixture.
Described mineral manure slow release layer is formed by fused(calcium magnesium)phosphate, secondary calcium phosphate, magnesium ammonium phosphate one or its any mixture.
Described micro-layer selects one or more fertiliser mixtures of zinc sulphide, boric acid, ammonium molybdate, cupric oxide, iron protoxide, manganese oxide.
The utility model has the advantages that:
The utility model reasonable in design, by the structure of sodium polyacrylate water conservation layer and urease inhibitor slow release layer, mineral manure slow release layer, enhance slowly-releasing stability and water retention property, and by the structure of micro-layer and poly aspartic acid coating layer, trace element is wherein made to meet soil nutrient status and crop uptake characters, be conducive to Crop nutrient balance to absorb, promote crop growth, thus improve crop yield and quality.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
See accompanying drawing, a kind of large-particle long-acting slow-release nitrogen fertilizer, include urea ammonium nitrogenous fertilizer particle 1, urea ammonium nitrogenous fertilizer particle 1 is wrapped with sodium polyacrylate water conservation layer 2, sodium polyacrylate water conservation layer 2 is wrapped with attapulgite 3, attapulgite 3 is wrapped with urease inhibitor slow release layer 4, urease inhibitor slow release layer 4 is wrapped with mineral manure slow release layer 5, mineral manure slow release layer 5 is wrapped with poly aspartic acid coating layer 6, poly aspartic acid coating layer 6 is wrapped with micro-layer 7, and micro-layer 7 is wrapped with diatomite anti-caking layer 8.
Described urease inhibitor slow release layer 4 is formed by quinhydrones, N-NBPT, thiophosphoryl triamide, phosphoryl triamide one or its any mixture.Described mineral manure slow release layer 5 is formed by fused(calcium magnesium)phosphate, secondary calcium phosphate, magnesium ammonium phosphate one or its any mixture.Described micro-layer 7 selects one or more fertiliser mixtures of zinc sulphide, boric acid, ammonium molybdate, cupric oxide, iron protoxide, manganese oxide.
