Embodiment 1

[0029] (1) 35 parts of ammonium nitrate are heated to 110 DEG C to obtain the melt of ammonium nitrate; 27.1 parts of monoammonium phosphate and 25 parts of potassium chloride with particle size less than 1.0 mm are respectively heated to 120 DEG C;

[0030] (2) the melt of the ammonium nitrate of step (1) is mixed with the heated monoammonium phosphate and potassium chloride for 3min to obtain a molten slurry having nitrogen, phosphorus and potassium suspended matter;

[0031] (3) Mix the molten slurry containing nitrogen, phosphorus and potassium suspension obtained in step (2) with 5 parts of calcium oxide and 4.9 parts of magnesium chloride for 3 minutes to obtain a mixed slurry, and then add 1 part of magnesium sulfate that has been crushed to 60 meshes, boric acid 0.3 part, 0.5 part of zinc chloride, 1 part of active humus, 0.1 part of DA-6 and 0.1 part of polyacrylamide were mixed for 3 minutes, and granulated by a granulation device to obtain a multi-element fertilizer ...

Embodiment 2

[0033] The implementation method is as in Example 1, and the raw materials are weighed in proportion: 45 parts of ammonium bicarbonate, 25 parts of sodium dihydrogen phosphate, 17.8 parts of potassium chloride, 5 parts of calcium oxide, 0.9 part of magnesium sulfate, 1 part of sulfur oxide, and 0.5 part of borax , 0.5 parts of zinc oxide, 3 parts of humic active agent, DA-60.5g part, 0.8 part of polyacrylamide.

Embodiment 3

[0035] The implementation method is as in Example 1, and the raw materials are weighed in proportion: 40 parts of urea, 30 parts of sodium dihydrogen phosphate, 20 parts of potassium sulfate, 4 parts of calcium hydroxide, 1.9 parts of magnesium chloride, 2 parts of ammonium sulfate, 0.4 parts of borax, zinc oxide 0.4 parts, humic active agent 1 part, DA-60.1g part, polyacrylamide 0.2 part.

Abstract

The invention discloses a multi-element fertilizer synergist and a production method, relates to a synergist and a stabilizer which are added in fertilizer containing nitrogen and phosphorus fertilizer, and belongs to the field of synergistic fertilizer. The multi-element fertilizer synergist is prepared from the following raw materials of, by weight, 35-45% of nitrogen, 25-35% of phosphorus, 15-25% of potassium, 1-5% of calcium, 0.9-4.9% of magnesium, 1-3% of sulfur, 0.3-0.5% of boron, 0.3-0.5% of zinc, 1% of active humus, 0.1-0.2% of plant hormones and 0.1-0.2% of drought-resistant and water-absorbent agent. The multi-element fertilizer synergist has the advantages that the multi-element fertilizer synergist is high in solubility and free of nutrient residual, and can obviously enhance permeation capacity and adhesion capacity of the fertilizer and improve the capacity and the speed of the fertilizer entering plant bodies.

Description

technical field [0001] The invention relates to a synergist and a stabilizer added to nitrogen-containing fertilizers and phosphorus fertilizers, belonging to the field of synergistic fertilizers, in particular to a multi-element fertilizer synergist and a production method. Background technique [0002] In the field of agriculture, the use of fertilizers has been very extensive; however, due to environmental, crop or meteorological reasons, only a part of the applied fertilizer is absorbed by the crops, and most of the fertilizer is seriously lost due to leaching, volatilization or mineralization, resulting in fertilizer Waste of resources, low utilization rate of fertilizers by crops, pollution of soil or water due to residual fertilizers, soil compaction, oxidative enrichment of surface water, etc., increase the cost of fertilization. If the amount of fertilizer is large, it is easy to cause crop burns. Therefore, research on fertilizer synergists to improve fertilizer ut...
