Abstract
A boron-containing diammonium phosphate fertilizer comprises diammonium phosphate, ammonium sulfate and boric acid, wherein diammonium phosphate accounts for 83%-87% of the ratio of the fertilizer, ammonium sulfate accounts for 12%-16% of the ratio of the fertilizer, and boric acid accounts for 1%-2% of the ratio of the fertilizer. The Meijia boron-containing diammonium phosphate fertilizer can effectively increase the persistence on crops, improves the utilization rate of nitrogen in the fertilizer, reduces the loss of the in-season fertilizer, can allow the nitrogen loss to be reduced by 63%, and saves the fertilizer using amount by 20%-30%; and under a condition that the fertilization amount is decreased by 25%, the crop yield is increased by 8%-18%.
Description
technical field:
The present invention relates to fertilizer field, particularly a kind of diammonium phosphate of boracic is fertile.
background technology:
Strong phosphoric acid and ammonia after neutralization reaction, are squeezed in tablets press through shurry pump in neutralizing well, carry out granulation, final production diammonium phosphate, and in the use of farm crop, effect is very good.Only have at present nitrogenous, phosphorous a kind of product, product is more single, and the utilization ratio of fertilizer is lower.
summary of the invention:
In view of this, be necessary to provide a kind of diammonium phosphate of boracic fertile, the object of the invention is on existing production technique basis, in fertilizer, increase boron and wrap up, produce slow release fertilizer, to increase trace element in fertilizer, improve high-level efficiency and the utilization ratio of fertilizer, diversify, make product diversification, enrich currently available products production line.Reduce the pollution to environment simultaneously.
A kind of diammonium phosphate of boracic is fertile, comprises diammonium phosphate, ammonium sulfate, boric acid, and wherein diammonium phosphate accounts for 83% to 87% of fertilizer ratio, and ammonium sulfate accounts for 12% to 16% of fertilizer ratio, and boric acid accounts for 1% to 2% of fertilizer ratio.
The diammonium phosphate fertilizer of boracic has improved the persistence to farm crop effectively, has improved Nitrogen utilization ratio, reduces this season fertilizer loss, can make nitrogen loss reduce 63%, saves fertilizer amount 20% ~ 30%; In the situation that rate of fertilizer application reduces 25%, crop yield 8% ~ 18%.
embodiment:
The diammonium phosphate of boracic is fertile, comprise diammonium phosphate, ammonium sulfate, boric acid, wherein diammonium phosphate accounts for 83% to 87% of fertilizer ratio, ammonium sulfate accounts for 12% to 16% of fertilizer ratio, boric acid accounts for 1% to 2% of fertilizer ratio, and in the present embodiment, diammonium phosphate accounts for 85% of fertilizer ratio, ammonium sulfate accounts for 14% of fertilizer ratio, and boric acid accounts for 1% of fertilizer ratio.
The diammonium phosphate fertilizer of boracic makes by following steps:
The slurries that comprise diammonium phosphate that in pre-neutralization device, ammonia and strong phosphoric acid, ammonium sulfate and the micro-nutritive salt that contains manganese mixed and obtain;
According to predefined procedure, slurries, ammonia, Nutrient Transportation are delivered in tablets press, with utilize tablets press to nutritive salt, slurries, ammonia, carry out granulation operation, and form the diammonium phosphate molectron containing manganese;
Utilize moisture eliminator, sifter that the diammonium phosphate molectron of boracic is dried and is screened, to obtain the diammonium phosphate fertilizer of boracic.
The making equipment of the diammonium phosphate fertilizer of boracic comprises ammonia tank, strong phosphoric acid tank, handling equipment, pre-neutralization device, shurry pump, tablets press, moisture eliminator and sifter; Handling equipment is for delivering to the Nutrient Transportation of boracic in tablets press; The strong phosphoric acid that pre-neutralization device provides with strong phosphoric acid tank for the ammonia that ammonia tank is provided mixes to obtain the slurries that comprise diammonium phosphate; Shurry pump is for being transported to slurries in tablets press; Tablets press is used for slurries, nutritive salt, ammonia, carries out granulation operation, and forms the diammonium phosphate molectron of boracic; Moisture eliminator is for being dried the diammonium phosphate molectron of boracic; Sifter is for the diammonium phosphate molectron of dried boracic is screened, to obtain the diammonium phosphate fertilizer of boracic.
The diammonium phosphate fertilizer of boracic has improved the persistence to farm crop effectively, has improved Nitrogen utilization ratio, reduces this season fertilizer loss, can make nitrogen loss reduce 63%, saves fertilizer amount 20% ~ 30%; In the situation that rate of fertilizer application reduces 25%, crop yield 8% ~ 18%.
