Abstract
The invention relates to a fertilizer, in particular to a granular calcium cyanamide compound fertilizer and a technique for processing the same. The granular calcium cyanamide compound fertilizer comprises the following components according to the total weight: 10 to 80 percent of calcium cyanamide, 10 to 80 percent of adding components, and 5 to 30 percent of caking agent, wherein the adding components comprise one or more than one of animal wastes, plant straws, decomposed coal, humic acid and humic acid magnesium; and the caking agent is one or more than one of urea, ammonium nitrate and calcium nitrate. The processing technique comprises the steps of crushing, stirring and granulating. The processing technique uses the characteristics of easy decomposition of the adding components in water and difficult decomposition of the caking agent in air, solves the problems that the prior calcium cyanamide is easy to decompose in the air and is not easy to dissolve in the water, effectively exerts the properties of long lasting manurial effect of the calcium cyanamide in soil and slow absorption by crops, has the characteristics of certain weeding and sterilizing effects, and can prevent causing harm to health of human body during use at the same time after the fertilizer is manufactured into granules.
Description
Affiliated technical field
The present invention relates to a kind of fertilizer, particularly particle calcium cyanamide composite fertilizer and complete processing thereof.
Background technology
Calcium cyanamide is as a kind of chemical fertilizer, has slowly-releasing, advantage such as long-acting, but owing to separately in the use, protects improper meeting to work the mischief to health, so people think head it off at present always.As China Intellectual Property Office's on April 2nd, 2003 disclosed " stable enhanced efficiency controllable release calcium cyanamine " by name, the patent of invention of publication number: CN1407957A, its main component is calcium cyanamide and urea, utilize the various combination granulation of calcium cyanamide and urea, be made into the slow fertilising of particulate state.The shortcoming of such scheme is a calcium cyanamide when meeting water decomposition, can form the water-fast shell of one deck, influences its fertilizer efficiency, and calcium cyanamide is divided into powdery in air simultaneously, and its fertilizer efficiency is reduced.
Summary of the invention
The purpose of this invention is to provide a kind of differentiation that in air, is difficult for, dissolving easily in water, particle calcium cyanamide composite fertilizer and complete processing thereof easy to use.
Technical scheme of the present invention is: a kind of particle calcium cyanamide composite fertilizer, comprise calcium cyanamide, added ingredients that accounts for gross weight 10-80% that accounts for gross weight 10-80% and the binding agent that accounts for gross weight 5-30%, wherein added ingredients is that one or more of animal excrement, straw, weathered coal, humic acids, humic acids magnesium are composite, and binding agent is that one or more of urea, ammonium nitrate, nitrocalcite are composite.
A kind of complete processing of making particle calcium cyanamide composite fertilizer; it is characterized in that; technological process comprises: one or more of the animal excrement of added ingredients, straw, weathered coal, humic acids, humic acids magnesium are composite; crushed after being dried is to 5mm; add calcium cyanamide then and be ground into pulverous binding agent; after stirring, utilize the non-slurry pelletizing machine to cause the particle of 1-5mm, cooling back packing is finished product calcium cyanamide composite fertilizer.
The present invention utilizes the characteristics that added ingredients easily decomposes and binding agent is difficult for decomposing in air in water, having solved present calcium cyanamide breaks up and not diffluent problem in water in air easily, it is lasting effectively to have brought into play calcium cyanamide fertilizer efficiency in soil, can slowly be absorbed by crop, and have certain weeding, characteristics of sterilization effect, after making particle simultaneously, can solve when using harm to HUMAN HEALTH.
Embodiment
To make 100kg particle calcium cyanamide composite fertilizer is example, describes as follows:
Embodiment 1:
At first 40kg cow dung is crushed to less than 5mm square particle, after stirring with the calcium cyanamide of 50kg and 10kg urea then, puts into the non-slurry pelletizing machine, be squeezed into the particle of diameter 2mm, cooling back packing is finished particle calcium cyanamide composite fertilizer.
Embodiment 2-13:

| 7 | 50 | 40kg humic acids magnesium | 10kg nitrocalcite |
| 8 | 80 | 10kg sheep excrement | 10kg urea |
| 9 | 80 | The 10kg wheat straw waste | 10kg ammonium nitrate |
| 10 | 80 | The 10kg rice straw | 10kg nitrocalcite |
| 11 | 10 | The 80kg weathered coal | 10kg urea |
| 12 | 10 | The 70kg humic acids | 20kg ammonium nitrate |
| 13 | 10 | 60kg humic acids magnesium | 30kg nitrocalcite |
In the above-described embodiments, under the situation that does not change calcium cyanamide and binder amount, change the proportion relation of added ingredients, promptly adopt animal excrement, straw, weathered coal, humic acids, one or more composite forms of humic acids magnesium, all can be made into particle calcium cyanamide composite fertilizer.
In the above-described embodiments, when 10-80kg changed, the amount of binding agent changed at 5-30kg with the amount of calcium cyanamide, kept 100kg as long as guarantee the total amount that added ingredients adds calcium cyanamide and binding agent this moment, can both make particle calcium cyanamide composite fertilizer.Above-mentioned added ingredients is animal excrement, straw, weathered coal, humic acids, one or more composite forms of humic acids magnesium.
Claims (2)
1, a kind of particle calcium cyanamide composite fertilizer, comprise calcium cyanamide, added ingredients that accounts for gross weight 10-80% that accounts for gross weight 10-80% and the binding agent that accounts for gross weight 5-30%, wherein added ingredients is that one or more of animal excrement, straw, weathered coal, humic acids, humic acids magnesium are composite, and binding agent is that one or more of urea, ammonium nitrate, nitrocalcite are composite.
