Problems solved by technology

[0003] At present, the existing humic acid water-soluble fertilizers are mainly composed of humic acid, nitrogen, phosphorus, potassium and other elements. Due to the limitation of the extraction process and activity of mineral humic acid, the anti-flocculation performance and activity of humic acid in most humic acid water-soluble fertilizers are low. Not ideal, so the corresponding effect cannot be achieved after use
Some also add hormone ingredients, although it can make the crops mature earlier, but premature senescence occurs later, and the yield and quality decline

[0021] The effect of the product of this embodiment: the high-activity potassium humate is used as the raw material, and the anti-flocculation performance and activity of the humic acid are high.

Embodiment 2

[0023] A kind of humic acid-containing water-soluble fertilizer comprises the following components by mass percentage:

[0024] 12% urea, 2.5% potassium sulfate, 15% potassium dihydrogen phosphate, 7.5% potassium humate, 0.6% defoamer, 0.4% synergist, 62% water.

[0025] The effect of the product of this embodiment: the high-activity potassium humate is used as the raw material, and the anti-flocculation performance and activity of the humic acid are high. High phosphorus and high potassium, suitable for beans and underground root crops, improving quality and yield, green and efficient.

Embodiment 3

[0027] A kind of humic acid-containing water-soluble fertilizer comprises the following components by mass percentage:

[0028] 20% urea, 2% potassium sulfate, 10% potassium dihydrogen phosphate, 8% potassium humate, 0.4% defoamer, 0.6% synergist, 59% water.

[0029] The effect of the product of this embodiment: the high-activity potassium humate is used as the raw material, and the anti-flocculation performance and activity of the humic acid are high.

[0030] Nitrogen control and slow release, phosphorus solution and efficiency enhancement, potassium leaching prevention, and activation of micronutrient elements. It has a strong adsorption effect on metal ions and organic pollutants, and alleviates soil pollution caused by heavy metals and organic pollutants.

Abstract

The invention relates to a humic acid containing water-soluble fertilizer. The humic acid containing water-soluble fertilizer contains the following ingredients in percentage by mass: 12-20% of urea, 2-3% of potassium sulfate, 8-15% of potassium dihydrogen phosphate, 6-11% of potassium humate, 0.2-0.6% of antifoamer, 0.2-0.6% of synergist and 50-70% of water. A preparation method for the humic acid containing water-soluble fertilizer comprises the following steps of adding hot water into a reactor, firstly, dissolving the 12-20% of urea, then, dissolving the 2-3% of potassium sulfate, carrying out dissolving while carrying out stirring, then, dissolving the 8-15% of potassium dihydrogen phosphate, adding the 6-11% of potassium humate into the reactor, carrying out stirring for 2 hours, then, adding the 0.2-0.6% of antifoamer and the 0.2-0.6% of synergist into the reactor, carrying out water supplementing until the volume of the solution is 1,000L, and carrying out standing for 24 hours. The humic acid containing water-soluble fertilizer has the characteristics of economical efficiency, safety, convenience and high efficiency.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a humic acid-containing water-soluble fertilizer and a preparation method thereof. Background technique [0002] Water Soluble Fertilizer (Water Soluble Fertilizer, referred to as WSF) refers to a multi-element compound fertilizer that can be completely dissolved in water. It has obvious advantages such as instant dissolution, high absorption rate, quick effect, no residue, and convenient application. Water-soluble humic acid fertilizer refers to a liquid or solid water-soluble fertilizer made of humic acid in a proportion suitable for plant growth, adding an appropriate amount of nitrogen, phosphorus, potassium macroelements or zinc, boron, iron, molybdenum, manganese, copper and other trace elements . Water-soluble humic acid fertilizer is dissolved or diluted in water, and is used for irrigation and fertilization, foliar fertilization, soilless cultivation, so...
