Special water-soluble fertilizer for cucumbers and preparation method thereof

Abstract

The invention discloses a special water-soluble fertilizer for cucumbers and a preparation method thereof, and belongs to the technical field of a water-soluble fertilizer. The special water-soluble fertilizer is prepared from the following raw materials in parts by weight: 25 to 30 parts of urea, 15 to 25 parts of industrial monoammonium phosphate, 45 to 55 parts of potassium nitrate, 10 to 14 parts of calcium nitrate, 0.2 to 0.4 part of hydrochloric acid and 60 to 80 parts of deionized water. The method comprises the following steps of 1, heating deionized water to 95 to 98 DEG C; 2, addinghydrochloric acid according to the proportioning ratio; performing uniform stirring; 3, adding hydrochloric acid according to the proportioning ratio; performing uniform stirring; 3, adding industrialmonoammonium phosphate according to the proportioning ratio; performing stirring to complete dissolution; performing uniform mixing; 4, adding potassium nitrate and urea according to the mixture ratio; performing stirring to complete dissolution; performing uniform mixing; 5, slowly adding calcium nitrate into the materials according to the mixture ratio; after the addition is completed, performing uniform stirring; 6, after spray drying, performing cooling to obtain a finished product. The fertilizer has the advantages that the particle fineness is good; the water-soluble speed is high; thecucumber yield can be improved, and the like.

Description

technical field [0001] The invention belongs to the technical field of water-soluble fertilizers, in particular to a special water-soluble fertilizer for cucumbers and a preparation method thereof. Background technique [0002] Water-soluble fertilizers refer to chemical fertilizers that can completely dissolve in water without residues. They are characterized by high content (total nitrogen, phosphorus, and potassium content ≥ 50%) and less water-insoluble matter (≤ 5%). They are suitable for water-soluble spraying and drip irrigation. A class of chemical fertilizers fertilized in other ways. Most of the water-soluble fertilizers produced by enterprises now use the blending process, that is, the raw materials of different components are crushed and blended together to form the final product. The disadvantage of this process is that the different components that make up the fertilizer have different dissolution rates in water. After the fertilizer is put into water, some co...

Problems solved by technology

The disadvantage of this process is that the different components that make up the fertilizer have different dissolution rates in water. After the fertilizer is put into water, some components dissolve quickly and some components dissolve slowly, which affects the overall dissolution rate.

[0033] The applicant found that the above method not only needs to add an anti-caking agent, but also the solubility of the finished fertilizer is not good, and the coexistence of phosphorus and calcium is not as good as the applicant said

[0034] In addition, in practice, water-soluble fertilizers also have the disadvantage of being difficult to completely mix evenly, and due to time constraints, it is difficult for farmers to wait until the fertilizer is completely dissolved and stirred evenly before starting fertilization operations, resulting in inconsistent fertilization concentrations in different regions, thus Affected the effect
