Abstract
A long-acting compound fertilizer features that 0.2-0.8 wt.% N fertilizer synergist is added to it for elongating its active period by 100-150 days and increasing the utilization rate of N by 15-20% .Its advantages are increasing yield saving fertilizer and saving labour.
Description
What the present invention relates to is a kind of compound manure and manufacturing process thereof, a kind of specifically long-acting specific composite fertilizer material and manufacturing process thereof.
Production at present and the compound fertilizer special that uses, mostly being nitrogen, phosphorus, potassium and trace element forms, 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) is at the bottom of the utilization ratio (about 35%), so in crop growth, later stage also will repeatedly impose nitrogenous fertilizer in order to satisfy the required nitrogen nutrition of crop growth.
The present invention be directed to above-mentioned existing problems, it is long to propose a kind of fertilizer efficiency period, long-acting specific composite fertilizer that utilization ratio is high and manufacturing process thereof.
Nitrogen fertilizer potentiating agent is a kind of auxiliary agent that improves the nitrogen fertilizer efficiency, divides two kinds of nitrification inhibitor and urease inhibitors, and it can improve the utilization ratio of nitrogenous fertilizer effectively, prolongs its fertilizer efficiency period, makes agricultural reach volume increase, increases income, economizes fertilizer, saving of labor's net effect.Present existing technology is that nitrogen fertilizer potentiating agent and nitrogenous fertilizer are used, or makes long-acting nitrogen fertilizer such as long-acting carbamide and long-term efficiency bicarbonate ammonium etc., also never has nitrogen fertilizer potentiating agent is added precedent in the composite fertilizer special.Feature of the present invention is the nitrogen fertilizer potentiating agent that adds its nitrogenous fertilizer weight 0.2～0.8% in composite fertilizer special, nitrogenous fertilizer comprises: urea, liquefied ammonia, sulphur ammonium, ammonium nitrate, ammonium chloride etc., nitrogen fertilizer potentiating agent comprises: urease inhibitor hydroquinone (Resorcinol) and nitrification inhibitor Dyhard RU 100 (Dicyanodiamide) etc.The production technique of the long-acting specific composite fertilizer of above-mentioned formation has two kinds: 1. granulating method production technique: with powdery base fertilizer and synergistic agent (or making powdery) is raw material, heat by humidification, granulation in rotary drum or garden dish machine, the long-acting specific composite fertilizer that contains synergistic agent is made in the drying moulding.This method is fit in the production, the middle-size and small-size producer of lower concentration product.2. slurry process production technique: be a kind of compound manure production technique 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.This technology is fit to produce the large and medium-sized enterprise of middle and high concentration product.
The characteristics of long-acting specific composite fertilizer are: owing to added synergistic agent in the composite fertilizer special, can make the fertilizer efficiency period of composite fertilizer special extend to 100～150 days, nitrogen utilization efficiency improves 15～20%, the fertile process of confession of composite fertilizer special and the regulation of fertilizer requirement of crop are coordinated substantially, better met the nutritional needs of three breeding times of crop, reached volume increase, increase income, economize fertilizer, saving of labor's net effect.Particularly to overlay film, exempt to intertill, new agricultural technology that inconvenience such as rice field fish culture is topdressed, played irreplaceable vital role, solved the crucial difficult problem that these technology inconvenience are topdressed, make these new technologies bring into play its effect of increasing production better.
This technology is suitable for various composite fertilizer specials such as cotton, corn, wheat, tobacco, fruit tree, vegetables etc., composite fertilizer special can be by adding nitrogen fertilizer potentiating agent, make corresponding long-acting specific composite fertilizer, its production technique can only be done a small amount of investment and change and can go into operation on the basis of original production composite fertilizer special.
Example 1 cotton long-acting specific composite fertilizer granulating method production technique
Nitrogen fertilizer potentiating agent is that the part by weight of nitrogenous fertilizer in urease inhibitor hydroquinone (Resorcinol) and the composite fertilizer special is 0.3% adding, burden process in its production technique adds quinhydrones with this ratio, stir then, make the cotton long-acting specific composite fertilizer that adds synergistic agent through granulation, drying forming.
Example 2. corn long-acting specific composite fertilizer slurry process production technique
Nitrogen fertilizer potentiating agent is that the part by weight of nitrogenous fertilizer in nitrification inhibitor Dyhard RU 100 (Dicyanodiamide) and the composite fertilizer special is 0.6% adding, generate 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 specific composite fertilizer that adds synergistic agent then.
Example 3 wheat long-acting specific composite fertilizer granulating method production technique
Nitrogen fertilizer potentiating agent is that the part by weight of nitrogenous fertilizer in urease inhibitor hydroquinone (Resorcinol) and the composite fertilizer special is 0.2% adding, add quinhydrones at the burden process of producing with aforementioned proportion, right stirs, and the granulation drying forming is made the wheat long-acting specific composite fertilizer that adds synergistic agent.
Example 4 tobacco long-acting specific composite fertilizer slurry process production technique
Nitrogen fertilizer potentiating agent is that the part by weight of nitrogenous fertilizer in nitrification inhibitor Dyhard RU 100 (Dicyanodiamide) and the composite fertilizer special is 0.7% adding.Earlier make slip with phosphoric acid and ammonia, add Dyhard RU 100 and other material fertilizers more according to the above ratio, the tobacco long-acting specific composite fertilizer that adds Dyhard RU 100 is made in granulation then.
Use urease inhibitor hydroquinone and nitrification inhibitor Dyhard RU 100 respectively, adopt different ratios and production technique can produce the long-acting specific composite fertilizer of various crops such as beet, fruit tree and vegetables.
