Abstract

The invention belongs to the field of a soil fertilizer, in particular to a sulfur-nitrogen fertilizer using ammonium bicarbonate as nitrogen sources. Ammonium bicarbonate, ammonium sulphate and calcium carbonate with low price are used as major raw materials for producing the fertilizer with the advantages that the nitrogen content is up to standard, at the same time, the sulfur content also reaches the requirement of the soil, the crop growth can be promoted, the crops have luxuriant foliage and are green, and the sulfur element in the fertilizer can promote various kinds of chemical reaction in plant bodies. The fertilizer can neutralize the redundant alkali in the soil and has the effect of regulating the acid base balance. The raw materials have low price, the fertilizer with the sufficient nitrogen content and with the sulfur content reaching the requirement of the soil can be used by farmers, and in addition, the plant cost of the farmers is also reduced.

Description

A kind of is the sulfur-nitrogen fertilizer of nitrogenous source with the carbon ammonium

Technical field

The invention belongs to the soil and fertilizer field, particularly a kind of is the sulfur-nitrogen fertilizer of nitrogenous source with the carbon ammonium.

Background technology

The growth of various food crop, vegetables, fruit tree, tobacco and other cash crop all need apply fertilizer, but most peasant only is familiar with nitrogen on buying chemical fertilizer and using. phosphorus. and potassium nutrition fertilizer; Understand the few of sulphur nutrient; And element sulphur can promote the intravital many chemical reactions of plant, and the too much alkali of its ability sweetening of the soil works to regulate acid; The plant a lack of sulfur, Lao Ye. young leaves all can flavescence.According to pertinent data, there is the arable soil a lack of sulfur about 30% in China, and area reaches 600,000,000 mu; Also have to surpass 20% the potential a lack of sulfur of soil, area is about 3.6 hundred million mu, adds the fertilizer of selling on the present market that contains element sulphur and is mostly with the vitriolate of tartar to be that raw material increases sulphur content; Vitriolate of tartar costs an arm and a leg; Cost is high, and produced fertilizer price causes very big burden for vast farmers just with respect to higher economically.

Summary of the invention

The objective of the invention is to overcome the deficiency of above-mentioned technology, proposing a kind of is the sulfur-nitrogen fertilizer of nitrogenous source with the carbon ammonium, utilizes cheap carbon ammonium, ammonium sulfate, lime carbonate to be main raw material; It is up to standard to produce a kind of nitrogen content; Sulphur content also reaches the required fertilizer of soil simultaneously, has to promote plant growth, makes crop with luxuriant foliage and spreading branches in leafy profusion; Verdant emerald green, contained element sulphur can promote the intravital many chemical reactions of plant in the fertilizer.The too much alkali of its ability sweetening of the soil plays a part to regulate acid, and these several kinds of prices of raw and semifnished materials are very cheap again, and it is enough again that the peasant has promptly used nitrogen content, and sulphur content also reaches the required fertilizer of soil, and has reduced the peasant planting cost again.

For realizing the object of the invention, existing according to following technical scheme, this fertilizer is to be processed by following raw materials in weight portion:

Component title weight proportion

Carbon ammonium 60%-90%

Ammonium sulfate 20%-40%

Lime carbonate 20%-30%

The weight proportion of best each raw material of prescription of the present invention is:

Component title weight proportion

Carbon ammonium 70%-80%

Ammonium sulfate 10%-30%

Lime carbonate 10%-20%

The preparation method:

The carbon ammonium adds ammonium sulfate and is adding lime carbonate, after stirring, adds concentration again and be 25% ammoniacal liquor; Moisture controlled is in 70% scope; Can agglomeratingly get final product with holding, be squeezed into particle through pair roller extruding machine then, particulate hardness is wanted about 8 newton; Sift out through screen cloth, the finished product metering packing gets final product again.

Fertilizer of the present invention mainly is to lack according to soil to mix with carbon ammonium and ammonium sulfate; The carbon ammonium adds lime carbonate will reduce the content (N >=17.1%) of nitrogen, but after adding the ammonium sulfate of a certain amount of N >=20%, can make its nitrogen content return to N >=17.1%; Increased the content of sulphur in addition again; Lime carbonate mainly has been the granulated effect of extruding, and lime carbonate is water insoluble, but has increased the required calcium constituent of soil.

The side separates:

The carbon ammonium: the carbon ammonium is not have (sulphur) acid group nitrogenous fertilizer, and its three nutrients that component all is a crop do not contain deleterious intermediate product and final degradation production; Long-term application does not influence soil property, is one of safest nitrogen fertilizers, and another characteristics of carbon ammonium are that its ammonium ion more is prone to by the grogs sticking; So after it applies soil, be difficult for seepage flow mistake under water; The leaching loss amount only reaches 1/3rd to 1/10th (table 2-2) of other nitrogenous fertilizer, therefore, as long as the carbon ammonium can more fully contact soil; By the abundant sticking of grogs, the volatilization after using is high unlike other nitrogenous fertilizer.Under some condition, as on calcareous soil, also comparable other nitrogenous fertilizer reduce volatilization loss behind the deep placement.

Ammonium sulfate: (NH4) 2SO4 is commonly called as ammonium sulphate, the salt that sulfuric acid and ammonia react generate.Be the principal item of nitrogenous fertilizer the sixties in 20th century in the past, also provides one of main source of crop alimentary elementary sulfur.Character: claim the sulphur ammonium again.Pure article are colourless rhomboidal crystal, and are soluble in water.Density 1.769g/cm3 mainly as fertilizer, is applicable to various soil and crop for a long time.Element sulphur plays the balance soil acidity or alkalinity, and pH value was near 8 o'clock, and elements such as sulphur ferrimanganic all are difficult to plant and absorb, pH value 4.5 or when lower calcium magnesium phosphorus then be difficult for being absorbed by plant, deleterious element but becomes and is easy to be absorbed.

Lime carbonate: molecular formula CaCO3 major ingredient CaO accounts for 56.03%, and it is a kind of important inorganic mineral that Co2 accounts for 43.97% lime carbonate.From the geology angle, lime carbonate is exactly the natural mineral of earth shell.

Embodiment:

(1) get carbon ammonium 900kg, ammonium sulfate 50kg, lime carbonate 50kg,

(2) at first carbon ammonium, ammonium sulfate, lime carbonate are mixed, stir,

(3) adding concentration is 25% ammoniacal liquor, and moisture controlled stirs in 70% scope, and is promptly agglomerating with holding,

(4) put into pair roller extruding machine to the fertilizer that stirs and be squeezed into particle, particulate hardness is wanted about 8 newton,

(5) sift out particle with screen cloth, obtain the particulate state sulfur-nitrogen fertilizer.

Of the present invention is the sulfur-nitrogen fertilizer of nitrogenous source with the carbon ammonium; Be to combine oneself studying intensively hard for many years; From hundreds of groups prescription, get through testing repeatedly, the growths of farm crop there is good pushing effect; Increase soil fertility simultaneously, reduced the influence of disease and pest, improved the growth quality of crop.

Using of the present invention is the sulfur-nitrogen fertilizer of nitrogenous source with the carbon ammonium, and its production-increasing function is obvious.

With the contrast of equivalent composite fertilizer, amount of increase in production is:

Food crop raising the output 7-15%, vegetables raising the output 820%, other crop yields 5-15%.
