Abstract
The invention discloses a high-nitrogen urea-based compound fertilizer produced by a mixed method. The high-nitrogen urea-based compound fertilizer is prepared from urea, ammonium chloride, monoammonium phosphate, potassium chloride, ammonium bicarbonate and packing. The high-nitrogen urea-based compound fertilizer has the advantages that the urea-based compound fertilizer is produced by the mixed method, so that the dosage of the urea is reduced; the urea does not need to be molten; power consumption, cost of materials, and equipment running cost are reduced; generation of biuret is greatly reduced at the same time; the environment and the crop growth are protected; and the product is qualified in quality, good in appearance quality and simple in processing technology, and can be pelletized by steam after the materials are mixed.
Description
Technical field
The present invention relates to the agricultural fertilizer field, be specifically related to the high N urea-based compound fertilizer that a kind of use method that is mixed is produced.
Background technology
At present, high N urea-based compound fertilizer is adopted mostly in order to improve the content of nitrogen
Melt method production with urine, 2580 yuan/tons of its production costs.Urea melts the easy biuret that produces in groove high-temperature fusion process at urine, can bring injury to farm crop, and exhaust emissions can cause certain pollution to atmosphere.
Summary of the invention
Purpose of the present invention is exactly at present, high N urea-based compound fertilizer
In order to improve the content of nitrogen, mostly adopt urine to melt method production, 2580 yuan/tons of its production costs.Urea melts in groove high-temperature fusion process at urine and easily produces biuret, can bring injury to farm crop, and exhaust emissions can cause to atmosphere the deficiency of certain pollution, and a kind of use high N urea-based compound fertilizer that the method that is mixed is produced is provided.
The present invention is by urea, ammonium chloride, monoammonium phosphate, Repone K, carbon ammonium and media assemblage, and its weight part proportioning is:
The urea 32-37 that contains N amount 46%
The ammonium chloride 9-11 that contains N amount 25%
Contain P
2O
558% monoammonium phosphate 19-21
Contain P

555% monoammonium phosphate 15-17
Contain K
2The Repone K 8-10 of O60%
The carbon ammonium 2-4 that contains N amount 17%
Filler 9-10.
It also has the soil insect-killing sterilant, and its weight part proportioning is: the urea 32-37 that contains N amount 46%
The ammonium chloride 9-11 that contains N amount 25%
Contain P
