Problems solved by technology

[0003] 1. The phenomenon of flocculation and sedimentation often occurs, which not only affects the appearance quality of fertilizer products, but also leads to uneven dispersion of nutrients, which affects the fertilizer efficiency of fertilizer products
[0004] 2. The effect of increasing production is not obvious, and the cost of use is high. The reason is not that the nutrient content of the product is low, but because of poor permeability, poor absorption, and easy loss, resulting in ineffective use.
[0005] 3. The balance of nutrients is poor, which is not conducive to the balanced absorption of nutrients by plants

Embodiment 1

[0027] Embodiment 1 preparation humic acid liquid fertilizer

[0028] The formula is: 10.0% potassium humate, 5.0% sucrose monolaurate solution with a mass concentration of 2.0%, 25.0% urea, 15.0% potassium dihydrogen phosphate, 0.30% ferrous sulfate, 0.10% iron ethylenediaminetetraacetate, The balance is water.

[0029] The preparation method is: add potassium humate into water, stir to dissolve, then add potassium dihydrogen phosphate, stir to dissolve; heat to 90°C, add urea, stir to dissolve, and then add 2.0% lauric acid sucrose monoester solution, Mix well, and finally add ferrous sulfate and iron ethylenediaminetetraacetate, mix well, and obtain.

Embodiment 2

[0030] Example 2 Preparation of humic acid liquid fertilizer

[0031] The formula is: 12.0% potassium humate, 5.0% sucrose laurate monoester solution with a mass concentration of 2.0%, 20.0% urea, 12.5% ​​potassium dihydrogen phosphate, 0.25% ferrous sulfate, 0.05% iron ethylenediaminetetraacetate, The balance is water.

Embodiment 3

[0032] Example 3 Preparation of humic acid liquid fertilizer

[0033] The formula is: 12.5% ​​potassium humate, 4.5% sucrose laurate monoester solution with a mass concentration of 2.0%, 23.0% urea, 10.0% potassium dihydrogen phosphate, 0.30% ferrous sulfate, 0.10% iron ethylenediaminetetraacetate, The balance is water.

Abstract

The invention discloses a humic acid liquid fertilizer. The humic acid liquid fertilizer is prepared from the following raw materials of 10.0-12.5% of potassium humate, 4.5-5.0% of 2.0wt% lauric acid sucrose monoester solution, 20.0-25.0% of urea, 10.0-15.0% of monopotassium phosphate, 0.25-0.30% of ferrous sulfate, 0.05-0.10% of ethylenediamine tetreaceticacid ferric, and the balance of water. The humic acid liquid fertilizer has the advantages that by reasonably adding additive, the inorganic nutrients can be dispersed and dissolved, so that the stability of liquid fertilizer is improved, the content of nutrients is increased, the permeating property of nutrients is effectively improved, and the effectivity and absorbing speed of nutrients are greatly improved; under the double functions of dispersing and catalytic stimulation, the activity of nutrients is improved; by reasonably proportioning organic nutrients, inorganic nutrients and trace elements, the balance of nutrients is solved.

Description

technical field [0001] The invention relates to a humic acid liquid fertilizer and its application in soilless cultivation of radish. Background technique [0002] There are following deficiencies in the liquid fertilizers currently on the market: [0003] 1. The phenomenon of flocculation and sedimentation often occurs, which not only affects the appearance quality of fertilizer products, but also leads to uneven dispersion of nutrients, which affects the fertilizer efficiency of fertilizer products. [0004] 2. The effect of increasing production is not obvious, and the cost of use is high. The reason is not that the nutrient content of the product is low, but because of poor permeability, weak absorption, and easy loss, resulting in ineffective use. [0005] 3. The balance of nutrients is poor, which is not conducive to the balanced absorption of nutrients by plants. [0006] Therefore, it is necessary to improve it. Contents of the invention [0007] Aiming at the a...
