Abstract
The present invention is adding nitrogen fertilizer synergist 0.05-0.5 wt% special compound fertilizer. The present invention makes it possible for the special compound fertilizer to have fertilizer effect period prolonged to 100-150 days, 20% raised nitrogen fertilizer utilization and fertilizer supplying course coordinated with the fertilizer needing regulation for crops. Thus, it is enough to use only base fertilizer and no topdressing.
Description
What the present invention relates to is a kind of compound fertilizer dedicated, a kind of specifically long acting special compound fertilizer material and production technique thereof.
Compound fertilizer dedicated nitrogenous fertilizer, phosphate fertilizer, potash fertilizer and the trace element fertilizer of mostly being of producing at present or using formed, some has also added organic materials and bacteria agent, wherein nitrogenous fertilizer mostly is urea and liquefied ammonia, because the fertilizer efficiency period of nitrogenous fertilizer short (40～60 days), utilization ratio low (about 35%) is so when making base manure with compound fertilizer special, in crop growth, later stage also needs to impose nitrogenous fertilizer in order to satisfy the required nitrogen nutrition of crop.
The present invention be directed to above-mentioned existing problems, to propose a kind of fertilizer efficiency period long, and the long acting special compound fertilizer that utilization ratio is high also provides its production technique.
Nitrogen fertilizer potentiating agent is a kind of auxiliary agent that improves the nitrogen fertilizer efficiency, divides nitrification inhibitor and urease inhibitor etc., and they can improve the utilization ratio of nitrogenous fertilizer effectively, prolong its fertilizer efficiency period, makes agricultural reach volume increase, joint fertilizer, saving of labor's comprehensive benefit.
Present prior art is that nitrogen fertilizer potentiating agent and nitrogenous fertilizer are used, or makes long-acting nitrogen fertilizer, as long-acting carbamide and long-term efficiency bicarbonate ammonium etc.; The technology of making durable composite fertilizer is also arranged, and (number of patent application: 96119508.8), but there is following weak point in this technology: 1. this durable composite fertilizer only is compound manure, does not comprise Bulk Blending Fertilizer, and bulk blended fertilizer is the direction of current fertilizer development; 2. the content of synergistic agent is to calculate in the ratio of nitrogenous fertilizer in the composite fertilizer in the existing durable composite fertilizer, and is indeterminate in concrete production, is difficult to operation (as diammonium phosphate, monoammonium phosphate is special-purpose fertile main raw material, whether can be regarded as nitrogenous fertilizer etc.); 3. the production technique that in production technique, does not also comprise Bulk Blending Fertilizer.
Feature of the present invention is that adding is the nitrogen fertilizer potentiating agent of its weight 0.05～0.5% (or its nitrogen content 0.1～5%) in compound fertilizer special.Nitrogen fertilizer potentiating agent comprises: nitrification inhibitor Dyhard RU 100 (Dicyanodiamide) and urease inhibitor hydroquinone (Resorcinol) etc., add-on is respectively 0～0.5% of a compound fertilizer special weight.The production technique of the long acting special compound fertilizer of above-mentioned formation has three kinds: 1. granulating method production technique: with powdery base fertilizer and synergistic agent (or making powdery) is raw material, by garden dish, rotary drum or extruder grain, make the long acting special compound fertilizer material that contains synergistic agent.2. slurry process production technique: be a kind of compound fertilizer production technology that combines with ammonium phosphate fertilizers, earlier with phosphoric acid and ammonia or sulfuric acid, ground phosphate rock and ammonia generation slip, add other base fertilizers and synergistic agent again, granulating and forming is produced long-acting specific composite fertilizer then.3. blending method production technique: be with each base fertilizer and synergistic agent granulation respectively, and then form the long acting special compound fertilizer material in the blending of partition ratio.
The characteristics of long acting special compound fertilizer material are: owing to added synergistic agent in the compound fertilizer special, can make the fertilizer efficiency period of compound fertilizer special extend to 100～150 days, nitrogen utilization efficiency improves more than 20%, the fertile process of confession of compound fertilizer special and the regulation of fertilizer requirement of crop are coordinated substantially, satisfied the nutritional needs of crop whole growing better, made agricultural reach volume increase, joint fertilizer, saving of labor's comprehensive benefit.Particularly to overlay film, exempt from intertillage, rice field fish culture, irrigation on plastic membrance and new agricultural technology such as irrigate and played irreplaceable vital role, solved the crucial difficult problem that these new technology inconvenience are topdressed, make it bring into play better effect.
This technology is suitable for various compound fertilizer specials, compound fertilizer dedicated as cotton, wheat, corn, paddy rice, tobacco, fruit tree and vegetables etc., the various compound fertilizer dedicated synergistic agent that can pass through to add, make corresponding long acting special compound fertilizer material, its production technique can be done investment less and change and can go into operation on the basis of original production compound fertilizer special.
Embodiment 1
Nitrogen fertilizer potentiating agent is quinhydrones (Resorcinol), add 0.1% of cotton compound fertilizer special weight, joining of granulating method production technique fertile operation add quinhydrones with this ratio, mix then, make the cotton long acting special compound fertilizer that adds quinhydrones through granulation, oven dry.
Embodiment 2
Nitrogen fertilizer potentiating agent is Dyhard RU 100 (Dicyanodiamide), with the weight ratio of corn special-purpose compound fertilizer be 2: 1000.Adopt the slurry process production technique, make slip with phosphoric acid and ammonia earlier, add Dyhard RU 100 and other material fertilizers more according to the above ratio, granulating and forming is made the corn long acting special compound fertilizer that adds Dyhard RU 100 then.
Embodiment 3
Nitrogen fertilizer potentiating agent is quinhydrones and Dyhard RU 100, be respectively 1.2 and (quinhydrones that is wheat compound fertilizer special weight respectively was 0.12% in 2.3: 1000 with the weight ratio of wheat compound fertilizer special, Dyhard RU 100 is 0.23%, sum total is 0.35%), adopt blending method production technique, above-mentioned synergistic agent is added in the micro-fertilizer raw material fertilizer, mix the back granulation, and then with other material fertilizer even blend of granulation, make the wheat long acting special compound fertilizer that adds quinhydrones and Dyhard RU 100.
Embodiment 4
Getting nitrogen fertilizer potentiating agent is urease inhibitor hydroquinone (Resorcinol), be 0.5% of paddy rice compound fertilizer special weight, add quinhydrones at the burden process of production technique with aforementioned proportion, then through mixing, through granulation, drying forming, make the paddy rice long acting special compound fertilizer material that adds quinhydrones.
Embodiment 5
Nitrogen fertilizer potentiating agent is nitrification inhibitor Dyhard RU 100 (Dicyanodiamide), be 0.25% of cotton compound fertilizer special weight, the synergistic agent of aforementioned proportion is added in the little fertilizer of raw material, mix granulation, then with the raw material emblem fertilizer of the interpolation synergistic agent of granulation, with the material fertilizer of other suitable grains, even blend is made the cotton long acting special compound fertilizer that adds synergistic agent.
Embodiment 6
Nitrogen fertilizer potentiating agent is 2 kinds of quinhydrones and Dyhard RU 100s, account for 0.15% and 0.25% of the fertile weight of compound respectively, above-mentioned 2 kinds of synergistic agent are added in the little fertilizer of raw material in proportion simultaneously, mix granulation, then with the little fertilizer of raw material of the interpolation synergistic agent of granulation, with other material fertilizer even blend of granulation, make the corn long acting special compound fertilizer that adds synergistic agent.
