Abstract
The invention discloses a tower type melt granulation stable nitrogen fertilizer and a preparation method. The nitrogen fertilizer contains synergistic components of potassium fulvate, N-(n-butyl)thiophosphoric triamide, 3,4-dimethyl-1h-pyrazolium dihydrogen phosphate and the like besides common nitrogen containing fertilizers of urea, ammonium sulfate, ammonium chloride, ammonium nitrate-phosphorus. The stable nitrogen fertilizer is manufactured by adopting a tower type melt granulation technology, the mechanical strength of granules is high and the granules are difficult to powder. Tests on corns, wheat, cucumbers and rice show that the stable nitrogen fertilizer can reduce the application amount of nitrogen fertilizer, yield increase is effective, the nitrate content in soil can also be reduced, and the stable nitrogen fertilizer is a green and environment-friendly excellent fertilizer.
Description
Technical field
The present invention relates to a kind of fertilizer, in particular to a kind of Tower-type melt granulation stability nitrogenous fertilizer and preparation method thereof.
Background technology
Nitrogenous fertilizer is a kind of artificial nutrient fertilizer mainly, has important effect for guarantee and raising crop yield.Though China has been at present production and marketing first big country of nitrogenous fertilizer in the world, about 50% of the utilization ratio Jin You developed country of China's nitrogenous fertilizer, the nitrogenous fertilizer lost not only has caused huge direct economic loss, also result in environmental pollution simultaneously.Therefore the utilization ratio improving nitrogenous fertilizer is extremely urgent.The kind of nitrogenous fertilizer has amide nitrogen fertilizer, ammonium fertilizer and nitrate fertilizer, and wherein crop directly absorbs ammonium nitrogen and nitric nitrogen, only directly absorbs micro-amidonitrogen, in the above two, the fastest with NO3--N translocation again.Nitric nitrogen very easily outflows with water and denitrification occurs to be become gaseous nitrogen oxide and enters in air, and this becomes the main path of loss of nitrogen fertilizer; Also easily ammonia volatilization is caused when the ammonium nitrogen concentration of Urea Transformation is too high simultaneously.Above-mentioned reason causes the utilization ratio of common nitrogenous fertilizer to be only about 30%, and fertilizer validity period also only has 30 days.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of Tower-type melt granulation stability nitrogenous fertilizer, this Tower-type melt granulation stability nitrogenous fertilizer can improve the utilization ratio of nitrogenous fertilizer, extend the fertilizer efficiency period of nitrogenous fertilizer, ensure that the crop later stage is for the demand of nutrient, cuts the waste and pollutes.
In order to solve the problems of the technologies described above, the present invention takes following technical scheme:
A kind of Tower-type melt granulation stability nitrogenous fertilizer, be made up by weight ratio of following raw material: 450 ~ 1000 parts, urea, potassium fulvate 20 ~ 90 parts, normal-butyl thiophosphoryl triamine 0.1 ~ 1.5 part, 3,4 dimethyl pyrazole phosphoric acid salt 0.2 ~ 1.2 part, and following raw material any one, two or three: 300 ~ 1000 parts, ammonium sulfate, ammonium chloride 300 ~ 1000 parts, 50 ~ 200 parts, ammonium nitrate phosphorus.
Preferably, described raw material and weight proportion are: 600 parts, urea, potassium fulvate 50 parts, normal-butyl thiophosphoryl triamine 0.9 part, 3,4 dimethyl pyrazole phosphoric acid salt 1.0 parts, 350 parts, ammonium sulfate, ammonium chloride 300 parts, 100 parts, ammonium nitrate phosphorus.
The present invention also provides a kind of preparation method of above-mentioned Tower-type melt granulation stability nitrogenous fertilizer, and technical scheme is:
A preparation method for above-mentioned Tower-type melt granulation stability nitrogenous fertilizer, is characterized in that comprising the steps: first the urea of described weight to be heated to 130 ~ 135 DEG C of meltings in fusion tank; Then add the ammonium sulfate of corresponding described weight, ammonium chloride, ammonium nitrate phosphorus also to complete melting, then add normal-butyl thiophosphoryl triamine, the potassium fulvate and 3 of described weight, 4 dimethyl pyrazole phosphoric acid salt, stir and obtain molten mixture; Then described molten mixture is promoted to the tower top of prilling tower, carries out sprinkling pelleting, form fertiliser granulates; Finally described fertiliser granulates is carried out sieving and cooling and pack.
Beneficial effect of the present invention is, select nitrogenous fertilizer and normal-butyl thiophosphoryl triamine, 3,4 dimethyl pyrazole phosphoric acid salt and potassium fulvate with the use of, be conducive to the direct utilization absorbed by crops of ammonium sulfate, ammonium chloride and ammonium nitrate phosphorus, make the hydrolysis of urea obviously be delayed simultaneously, effectively can reduce volatilization, be converted into the gaseous loss of oxynitride, the fertilizer efficiency period of this mixing nitrogenous fertilizer is made to extend to more than 100 days by about 30 days, utilization ratio improves more than 30%, quick acting and permanently effective taken into account by whole fertilizer, finally realizes increasing both production and income.Tower-type melt granulation technique is used to be prepared above-mentioned fertilizer, urea melting liquid can be used in granulation process to carry out other form nitrogenous fertilizer of melting, avoid adding of water etc., make the physical strength of particle and anti-caking performance good, more be conducive to normal-butyl thiophosphoryl triamine and 3,4 dimethyl pyrazole phosphoric acid salt and unclassified stores fully mix, and prevent loss.
