Mixed raw materials after bucket elevator promotes, is dropped into granulating disc or rotary drum granulator and carries out granulation.
(4), drying
When the particle of making reaches requirement in the tablets press; send in the rotary dryer; 140 ℃ of flue temperature temperature; carry out drying; 60 ℃ of dry back temperature of charge--70 ℃ granulated fertilizer turns round in the cooler, takes out cold wind (normal temperature) and carries out adverse current and ventilate and be cooled to below 35 ℃, sieves through sieve apparatus; qualified particle fertilizer is finished product through metering packing after the anti-caking of film applicator is handled.
The invention has the beneficial effects as follows,
One, the present invention has finished the single top coat of other slowly-releasing (or controlled release) fertilizer to inside and outside while controlled release and by the transformation of crude substance instead of chemical substance change fertilizer primary characteristic.With the humic acids is the organic composition of organic nitrogenous fertilizer (topdressing), with part urea surface coating, the fragmentation of part urea, drop into simultaneously the fermentation of sulphur ammonium and feces of livestock and poultry fertilizer, natural synergic agent (zeolite powder), natural glue (calcium-base bentonite) and in trace element constitute inside and outside controlled release simultaneously through mixing, granulation, drying, screening and become organic nitrogenous fertilizer (topdressing) product.
Two, the character of organic nitrogenous fertilizer of the present invention
Organic nitrogenous fertilizer is to be this fertile organic composition with humic acids, with urea (granular and powdery) and sulphur ammonium is novel the topdressing that nitrogen nutrient constitutes, wherein the organic composition humic acids is the quite complicated unformed organic compound of colloid of a kind of chemical structure, active group energy and K that it has
+, Na
+, Ca
2+, Mg
2+, Fe
3+, AL
3+And NH
4 +Form humate, and can generate complex compound or inner complex with some metal ion; In addition, the internal surface area of humic acids and cationic exchange energy are all very big.
1, the urase of humic acids suppresses and inhibiting nitrification
This organic nitrogenous fertilizer (topdressing) is to be that main organic composition, urea are the product of major nitrogen source processing with humic acids.After urea was manured into soil, under the effect of soil urease, very fast generation hydrolysis generated ammonia, an ammonia part in soil with H
2The O effect generates NH
4 +, be present in soil and be made for thing and absorb; Another part enters atmosphere.React as follows:
Humic acids is inhibited to soil activation, has greatly reduced the volatilization and the leaching loss of nitrogen; Along with the consumption of humic acids, can weaken its restraining effect gradually again, grow the heavy demand of vigorous period to adapt to crop to nitrogen.
Simultaneously, urea is manured into soil after hydrolytic action generates NH
4 +After, can be generated NO by the nitrite bacteria effect
2 -, under the effect of nitrobacteria, further be oxidized to NO again
3 -React as follows:
NO
3 -Though can be absorbed by crop, be easy to run off, cause nitrogen loss and water pollution.NO
3 -Under anaerobic condition, generate N through denitrification
2O and N
2, cause the loss and the topsoil of nitrogen.Through evidence, the nitrogen inhibiting rate of this organic nitrogenous fertilizer in soil reaches more than 70%.
2, humic acids stablizing to nitrogen
Humic acids has very big internal surface area and stronger adsorptive power.When hydrolysis of urea becomes NH
3And HN
3Become NH with hydration
4 +The time, adsorbed very soon, and generate humate by humic acids, not only reduced nitrogen loss, and well for plant-growth provides stable nitrogenous source, its reaction is as follows:
3, the reaction of humic acids and nitrogen phosphorus potassium
(1) and NH
4 +Reaction
Humic acids is water insoluble, with NH
4 +Reaction generates water-soluble ammonium humate, and it not only is easy to be absorbed by crop, and can reduce nitrogen loss.

Three, the implementation result of organic nitrogenous fertilizer
1, the effect of organic nitrogenous fertilizer (topdressing) is embodied in (1) improvement and fertilizing soil; (2) increase fertilizer usefulness, prolongation fertilizer efficiency time; (3) stimulate plant growth, increase crop yield, improve fruit quality; (4) alleviate water quality and topsoil, the protection environment; (5) economize on resources, save input, increase by five aspects of benefit.
(1) improvement and fertilizing soil
Humic acids is as the significant energy source of soil microorganisms and the matrix of soil beneficial microorganism breeding, can chessom, excite the decomposition of soil mineral, improve the physicals of soil, improve the buffering and the exchange capacity of soil, quicken the formation of soil granular, strengthen ventilation property, water-permeable and the fertilizer-preserving ability of soil.
(2) increase fertilizer usefulness, prolong the fertilizer efficiency time
Exist with molecular state during urea is manured into soil, and crop to molecular state urea absorb few, most urea molecules exist in the soil, and the ability of soil particle absorption urea molecule very a little less than, this has just caused a large amount of losses of urea nutrient.Owing to be rich in soil ulmin, a large amount of soil ulmin directly contacts and wraps up with urea molecule, makes that the functional group on the soil ulmin has abundant chance and NH in the organic nitrogenous fertilizer
4 +(product behind the hydrolysis of urea) contact, and with the form combination with it of covalent linkage, be fixed, fertilizer nutrient exempts from loss like this, and the crop need time spent is released.Confirm that through test this fertilizer not only fertilizer efficiency increases, and fertilizer efficiency period reached more than 110 days.Simultaneously, humic acids can activate the phosphorus element in the soil again, makes by the phosphorus of soil fixing and is converted into available phosphorus; Humic acids can also form colloidal compound with the Repone K that exists in the soil or vitriolate of tartar, makes the potassium element avoid running off, and has so just improved fertilizer usefulness widely, is example with urea, and its nitrogen utilization efficiency brings up to 56.1% by original 27.3%.
(3) stimulate plant growth, increase crop yield, improve fruit quality
Organic nitrogenous fertilizer has guaranteed the demand of plant growth later stage to nitrogen, simultaneously can activate the phosphorus element again, preservation potassium element, can also form complex compound or inner complex with trace element zinc, manganese, molybdenum, the copper plasma in the soil, be made for thing and absorb, this just makes crop demand nutrient obtain due guarantee, guarantee growing vigorously of crop, strengthen crop drought resistance, anti-adversity ability such as disease-resistant, thereby improved output, improved fruit quality.
(4) alleviate water quality and topsoil, the protection environment
This fertilizer has prevented the leaching loss and ease mistake of nitrogen effectively, suppresses the loss of potassium element, has improved utilization rate of fertilizer, has reduced nutrient loss, has so just alleviated water quality and atmospheric pollution, thereby has protected environment.
(5) economize on resources, save and drop into, increase benefit
Improve fertilizer usefulness, also just reduced the usage quantity of fertilizer, directly reduced resource consumption, saved resource indirectly; Fertilizer efficiency period is long, has just reduced the input in man-hour; Improved crop yield, improved fruit quality, also just improved the commodity rate of product, thereby increased economic benefit.
In a word, organic nitrogenous fertilizer is low the input, saves resource, reduces pollution, protection environment, increases the new-type fertilizer of benefit.
