preparation example Construction

[0025] A method for preparing a colorless organic water-soluble fertilizer, the preparation method comprising the following steps in sequence: first adding potassium salt into an acidic organic material liquid to obtain a colorless organic material liquid, and then adding a large amount of element solution and a trace element solution Add water to the colorless organic material liquid and perform sufficient chelation to obtain a chelating liquid, then add water to the chelating liquid and stir evenly to obtain a colorless organic water-soluble fertilizer.

[0026] The acidic organic material liquid refers to: first dissolving sodium hydroxide in water to form an alkali solution, then adding humic acid into the alkali solution and heating it to 90°C-100°C, and maintaining it at 1Pa-2Pa for 80 minutes- 100 minutes to obtain active humic acid liquid, then organic acid is added in active humic acid liquid, to obtain organic material liquid, then adjust the pH of organic material li...

Embodiment 1

[0044] A method for preparing a colorless organic water-soluble fertilizer, the preparation method comprising the following steps in sequence: first adding potassium salt into an acidic organic material liquid to obtain a colorless organic material liquid, and then adding a large amount of element solution and a trace element solution Add water to the colorless organic material liquid and perform sufficient chelation to obtain a chelating liquid, then add water to the chelating liquid and stir evenly to obtain a colorless organic water-soluble fertilizer.

Embodiment 2

[0046] Basic content is the same as embodiment 1, the difference is:

[0047] The acidic organic material liquid refers to: first dissolving sodium hydroxide in water to form an alkali solution, then adding humic acid into the alkali solution and heating it to 90°C-100°C, and maintaining it at 1Pa-2Pa for 80 minutes- 100 minutes to obtain active humic acid liquid, then organic acid is added in active humic acid liquid, to obtain organic material liquid, then adjust the pH of organic material liquid to obtain acidic organic material liquid;

[0048] The weight ratio of sodium hydroxide to water in the alkaline solution is 1:8 to 1:10, and the weight ratio of humic acid to the alkaline solution in the active humic acid solution is 1:6 to 1:10;

[0049] The pH value of the acidic organic material liquid is 3-6.

Abstract

The invention provides a preparation method for a colorless organic water-soluble fertilizer. The preparation method comprises the following successive steps: adding sylvite into acidic organic material liquid so as to obtain colorless organic material liquid; then adding a urea solution and a trace element solution into the colorless organic material liquid and carrying out adequate chelating so as to obtain chelated liquid; and adding water into the chelated liquid and carrying out uniform stirring so as to obtain the colorless organic water-soluble fertilizer. According to the invention, the sylvite is used as an oxidizing agent, an activator and a macroelement raw material, and in virtue of oxidizability of the sylvite, the colorless organic material liquid is completely decolored and activated. With the preparation method in the invention, the colorless organic water-soluble fertilizer is prepared and activity of an organic material is improved.

Description

technical field [0001] The invention belongs to the technical field of crop fertilizers, and in particular relates to a preparation method of a colorless organic water-soluble fertilizer, which is mainly suitable for preparing the colorless organic water-soluble fertilizer so as to improve the appearance quality of crops. Background technique [0002] Water-soluble fertilizers refer to multi-element compound fertilizers that can be completely dissolved in water. Compared with traditional superphosphate and granulated compound fertilizers, water-soluble fertilizers have obvious advantages. It is a quick-acting fertilizer with good water solubility and no residue. It can be completely dissolved in water and can be directly absorbed and utilized by the roots and leaves of crops. Water and fertilizer are applied at the same time, and water and fertilizer are used to realize the integration of water and fertilizer. Its effective absorption rate is more than double that of ordinar...
