By using ammonium carbonate as basic raw material, which is low in nutrient, high in water content, easy to volatilize and decompose, easy to cake and dissolve, and low in nitrogen utilization, and through mixing with certain amount of stabilizer to stabilize ammonium carbonate and pelletizing, and then the multi-element long-effect granular fertilizer is produced. It has nutritions element essential for crops and has no demerits of common ammonium carbonate fertilizer, the fertilizer is suitable for application with machinery and suitable for use in various soil and for various crpos, and has obvious yield increasing effect.
Description
The present invention relates to a kind of multiple-element long active granular ammonium carbonate fertilizer and manufacture method thereof, belong to the chemical industry class.
Multiple-element long active granular ammonium carbonate fertilizer is a kind of of granulated fertilizer.Granulated fertilizer is a particle (garden is spherical, oblate spheroid shape, strip or sheet) of one or more materials being made definite shape by physics or chemical process, change the physical properties (as moisture absorption, anti-caking) of fertilizer, or the surface in contact that reduces itself and air or soil is long-pending, decompose loss or leaching loss with the volatilization of minimizing fertilizer in transportation, storage or application, and reach the purpose of slowly-releasing, prolongation fertilizer efficiency, raising utilization rate of fertilizer.
Because bicarbonate of ammonia (hereinafter to be referred as the carbon ammonium) has free water content height (3.0%-6.5%) and chemical property instability, easily generation is lumpd, volatilized and decomposes, to very inconvenience of transportation, storage, use improper a large amount of losses that also can cause nitrogen and decompose shortcoming such as loss, cause fertilizer efficiency period short, nitrogen utilization efficiency is low, contaminate environment wastes energy.
For overcoming the above-mentioned shortcoming that carbon ammonium self exists, the someone attempts to develop macrobead carbon ammonium, coating carbon ammonium and long-term efficiency bicarbonate ammonium.But macrobead carbon ammonium is with the direct granulation of powdery carbon ammonium, it requires the water content of carbon ammonium extremely low (1% such low water content is difficult for reaching), otherwise be difficult for granulation, as if being the carbon ammonium granulation of one-level or seconds to contain the free water yield, then particle is bigger, weigh more than 1 gram, be unfavorable for mechanical fertilization, and owing to obviously do not improve the physical properties of carbon ammonium, the particle persistence is poor, nitrogen utilization efficiency improves limited, and has increased processing charges; Coating carbon ammonium is because its complex process, and the process-cycle is long, and cost is higher, and is uneconomical, and its coating thing is that majority such as paraffin-pitch can not be absorbed by crop; A kind of long-term efficiency bicarbonate ammonium that the patent CN1053225A of Shenyang Inst. of Applied Ecology, Chinese Academy of Sciences is introduced, it is the ammonium ion stablizer that in carbon ammonium production system, adds a kind of DCD of being called, though prolonged fertilizer efficiency effectively, improved nitrogen utilization efficiency, reduced loss and environmental pollution in the fertilising process.Its shortcoming is that it does not change outward appearance, does not increase other required nutritive element of crop, required fund is more, working cost is high, make the cost of long-term efficiency bicarbonate ammonium higher by about 25% than normal ammonium bicarbonate, increased peasant burden, applies difficulty.
The objective of the invention is to make a kind of have concurrently multielement, nutrient slowly-released, do not lump, resist leaching, fertilizer efficiency is long, nitrogen utilization efficiency is high, reduce the multiple-element long active granular ammonium carbonate fertilizer of multifrequency natures such as environmental pollution.The way of solution task is to be basic raw material with the normal ammonium bicarbonate, consumption is the 70%-98% of multiple-element long active granular ammonium carbonate fertilizer gross weight, with inexpensive and contain to soil and crop is useful or the calcium sulfate of nutritive element or rhombspar or fused(calcium magnesium)phosphate or magnesium oxide or sepiolite or zeolite or talcum or wilkinite or magnetic soil or sulphur in a kind of or by any two kinds or be carbon ammonium stablizer by any two or more the compound of material (it is Powdered to be 60 orders-200 purpose), its total consumption is the 2%-30% of multiple-element long active granular ammonium carbonate fertilizer gross weight, carry out extrusion molding by no drying extruder grain technology, form multiple-element long active granular ammonium carbonate fertilizer.Also can allocate phosphorus ammonium, vitriolate of tartar or Repone K as required into, and other trace element, to increase the available nutrient of product.
Adopt the product of manufacturing of the present invention, be to have improved outward appearance with the difference of other long-term efficiency bicarbonate ammonium, increased the available useful or nutritive element of soil or crop, itself and air or soil contacted specific surface area have been reduced, reduced the leaching loss after using, prolong fertilizer efficiency, improved nitrogen utilization efficiency.Sulfur-bearing or impurity is higher, the color burnt hair is brown, outward appearance is bad, carbon ammonium that be difficult for to sell in the also available substandard products carbon of the material carbon ammonium ammonium, and do not influence quality product.Selected stablizer is cheap and easy to get, helps formed product, and processing charges is low, very easily implements, and material cost is close with the normal ammonium bicarbonate cost or lower slightly, and this is a principal character of the present invention.
With the multiple-element long active granular ammonium carbonate fertilizer that the present invention makes, uniform particles, can change mechanical fertilization into by the spreading fertilizer over the fields of past, changed traditional fertilizing method, reduced the labour intensity of fertilising, improved work efficiency.
Another feature of the present invention is to have solved the easy agglomeration problems of carbon ammonium, prolonged the carbon ammonium storage period and use the phase, shortened factory's period of slack sales, reduced overstocking of stream money, and can reduce owing to carbon ammonium long storage caking must be made a price reduction enterprise and sell the loss that is caused more than 10%.
Manufacture method of the present invention adopts no drying extruder grain technology, and this technology principal character is that the carbon ammonium is a heat-sensitive material, is difficult for adding water or binding agent is dried, and can only adopt no drying extruder grain technology.All fertilizer secondary processing technologies of it and other compare that to have flow process the shortest, invest minimumly, and energy consumption is minimum, takes up an area of characteristics such as minimum, easy to implement.Figure of description is the technological process block-diagram of manufacture method among the present invention.
Multiple-element long active granular ammonium carbonate fertilizer and manufacture method embodiment thereof:
Get normal ammonium bicarbonate 70-98 part (weight part); if the long-term carbon ammonium that lumpd that overstocks then need be pulverized back adding mixing machine; other gets a kind of or any two kinds or two or more arbitrarily common 2-30 part (weight part) adding of compound substance mixing machines in calcium sulfate or rhombspar or fused(calcium magnesium)phosphate or magnesium oxide or zeolite or talcum or sepiolite or wilkinite or magnetic soil or the sulphur (being 60 orders-200 purpose flour); mix and make evenly; add Squeezinggranulator by feeding machine and carry out extruder grain, promptly get product.Also can add an amount of phosphorus ammonium, vitriolate of tartar or Repone K and trace element etc. in case of necessity.Packing can be divided into 25kg/ bag, 40kg/ bag, 50kg/ bag.
Multiple-element long active granular ammonium carbonate fertilizer has overcome the available nutrient that carbon ammonium self exists Low, the free water content height, volatile decomposition, caking, easily leaching runs off, and pollutes ring The border, the shortcoming such as fertilizer efficiency period is short, and nitrogen utilization efficiency is low.
