Abstract
The invention discloses a sulfur-containing ammonium phosphate fertilizer with an anti-caking function and a production method thereof. The sulfur-containing ammonium phosphate fertilizer is prepared from, by mass, 5-17% of nitrogen, 25-50% of active phosphorus pentoxide and 1-30% of sulphur. The production method includes the steps that sulphur emulsion is sprayed to uniformly wrap the surfaces of ammonium phosphate fertilizer granules, wherein the addition amount of the sulphur emulsion is 1-60% the mass of the ammonium phosphate fertilizer; the addition amount of the sulphur emulsion is adjusted; after drying, the ammonium phosphate granulated fertilizer with the corresponding sulphur content is obtained. According to the sulfur-containing ammonium phosphate fertilizer and the production method thereof, sulphur can be uniformly distributed on the surfaces of the ammonium phosphate granules, the potential hazards of sulphur are reduced, and sulphur in the product can be easily absorbed by plants; besides, the anti-caking function is achieved, it is not needed to add an anti-caking agent into the ammonium phosphate granules, and the sulfur-containing ammonium phosphate fertilizer is a good nitrogen, phosphorus and sulphur fertilizer.

Method, belongs to field of fertilizer manufacturing.
Background technology
Sulfur is one of required nutrient of crop, constitutes sulfur-containing amino acid and the basic nutrition element of protein.It is again
Can synthesize the physiological activities such as other important bioactive substances, the activation of participation enzyme, therefore, sulfur can regulate plant metabolism, carries
High yield and improvement crop product quality.A lack of sulfur not only inhibits crop yield, and reduces the quality of product, thus impact
To the mankind and the health of domestic animal.
Sulfur provides nutrient by direct each crop and improves the utilization rate of the required nutrient of other crop, particularly nitrogen and phosphorus,
Thus improve crop yield.Sulfur can also constitute synergism with zinc, promotes that zinc is absorbed by crops.
