Embodiment example 1

[0029] Implementation case 1. A kind of instant chelating solid water-soluble fertilizer, its component and proportioning ratio are as follows, all are percentage by weight:

[0030] 25% urea, 15% potassium dihydrogen phosphate, 20% superphosphate, 20% potassium sulfate, 2% magnesium chloride, 1% zinc sulfate, 1% manganese sulfate, 1% sodium molybdate, 1% ferrous sulfate, chelate Mixture 2%, heating agent 10%. The composition and ratio of the chelating agent are: amino acid powder : AMPS-chitosan polymer : AMPS-polyacrylamide copolymer : Polyepoxysuccinate=10:2:2:1. The composition and ratio of the heating agent are: calcium chloride: calcium oxide: sodium acetate = 6:2:2.

[0031] The preparation method is as follows:

[0032] 1) Material pretreatment: Pre-dry the heavy superphosphate in weight percentage, and then add a certain proportion of ammonium bicarbonate to neutralize the free phosphoric acid to obtain the neutralized heavy superphosphate, crush it to make i...

Embodiment example 2

[0035] Implementation case 2. As described in embodiment case 1, its difference is that each raw material component is as follows, is weight percent:

[0036] 30% urea, 10% potassium dihydrogen phosphate, 20% superphosphate, 20% potassium sulfate, 2% magnesium chloride, 1% zinc sulfate, 1% manganese sulfate, 1% sodium molybdate, 1% ferrous sulfate, chelate Mixture 4%, heating agent 8%. The composition and ratio of the chelating agent are: amino acid powder : AMPS-chitosan polymer : AMPS-polyacrylamide copolymer : Polyepoxysuccinate=10:2:2:1. The composition and ratio of the heating agent are: calcium chloride: calcium oxide: sodium acetate = 6:2:2.

Embodiment example 3

[0037] Implementation case 3. As described in embodiment case 1, its difference is that each raw material component is as follows, is weight percent:

[0038] 35% urea, 15% potassium dihydrogen phosphate, 15% calcium superphosphate, 15% potassium sulfate, 2% magnesium chloride, 1% zinc sulfate, 1% manganese sulfate, 1% sodium molybdate, 1% ferrous sulfate, chelate Mixture 6%, heating agent 6%.

Abstract

The invention relates to an instant chelated solid water-soluble fertilizer, particularly a chelated water-soluble fertilizer capable of heating a solution, belonging to the field of crop fertilizers. The water-soluble fertilizer comprises 25-40% of urea, 10-20% of potassium dihydrogen phosphate, 10-25% of double superphosphate, 10-25% of potassium sulfate, 2-6% of magnesium chloride, 0.5-3% of zinc sulfate, 0.5-3% of manganese sulfate, 0.5-4% of sodium molybdate, 0.5-2% of ferrous sulfate, 2-8% of chelator and 4-10% of heating agent. The preparation method of the water-soluble fertilizer comprises the following steps: carrying out ammonification pretreatment on double superphosphate for later use, chelating microelements with a chelator to obtain a chelated mixture, thoroughly mixing the treated double superphosphate, chelated mixture, macroelements and heating agent, pulverizing and packaging to obtain the instant chelated solid water-soluble fertilizer. The water-soluble fertilizer contains abundant microelements and overall nutrients; and the heating agent can increase the dissolution temperature, thereby enhancing the solubility of the components, increasing the dissolution rate and reducing the water consumption. The microelements are chelated by the chelator, thereby promoting the absorption and utilization of plants for macroelements and microelements; and thus, the fertilizer is suitable for various crops.

Description

technical field [0001] The invention belongs to the field of crop fertilizers, and more precisely relates to a water-saving chelating instant chelating solid water-soluble fertilizer. Background technique [0002] Water-soluble fertilizer is a multi-component compound fertilizer soluble in water. It is a new type of fertilizer that has emerged in recent years. It can be quickly dissolved in water, more easily absorbed by crops, and has a relatively high absorption and utilization rate, realizing the integration of water and fertilizer. , to achieve the effect of saving water, fertilizer and labor. my country is a large agricultural country with a large population and a serious shortage of water resources. The per capita share is equivalent to 1 / 4 of the world's per capita share. The share used for agricultural production is also declining, which has formed a very serious problem. In terms of agriculture , The vigorous development of water-saving fertilizers cannot wait. [...
