Abstract

The present invention discloses modified ammonium sulfate which is prepared from ammonium sulfate, bentonite, paraffin, and 3,4-dimethylpyrazole phosphate. According to the present invention, the modified ammonium sulfate has higher mechanical strength, reduces caking and powdering, reduces ammonia volatilization, increases a utilization rate after application in farmlands and solves the problem that common ammonium sulfate produces irritating odour after been heated in storage and in use.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a modified ammonium sulfate. Background technique [0002] Ammonium sulfate is a commonly used nitrogen fertilizer. It supplements nitrogen and sulfur at the same time. It is a nitrogen fertilizer with high cost performance. The production process of ammonium sulfate is simple and the production cost is low, which brings convenience for the large-scale application of ammonium sulfate. Powdered ammonium sulfate is prone to agglomeration during storage, and it is prone to pulverization and agglomeration after being made into granules. Ammonium sulfate quickly decomposes into ammonium and sulfate radicals after entering the soil. Because ammonium sulfate directly contacts the soil and there is no isolation barrier, the ammonia vapor pressure is too high in a short period of time after decomposition, and it is easy to run into the air and be lost. Crop fumigation, especially in alkaline soils. The ...
