preparation example Construction

[0021] A preparation method of organic water-soluble fertilizer, the method comprises the following steps:

[0022] 1) Chemically activate the organic material composed of humic acid and yeast concentrate, wherein the weight ratio of humic acid and yeast concentrate is 1:4 to 1:6, specifically dissolving KOH in water to form a dilute alkali solution, Then add humic acid to dilute alkali solution to dissolve, then add yeast concentrate, let it continue to hydrolyze at room temperature for 6-10 hours, add organic acid and yeast concentrate after hydrolysis is completed;

[0023] 2) Use KOH solution to adjust the pH of the organic material liquid, and the adjusted pH value is 8 to 8.5;

[0024] 3) Dissolve trace elements in water at 60-100°C and 0-2KPa, the weight ratio of trace elements to water is 1:10-1:30;

[0025] 4) The trace element solution is added to the organic material liquid at 60-80°C to fully chelate the organic material and trace elements. The volume ratio of the...

Abstract

The invention discloses a method for preparing an organic water-soluble fertilizer. The method comprises the following steps: chemically activating organic materials; regulating a pH value of the organic material liquid by using a KOH solution for later use; dissolving microelements into water at the temperature of 60-100 DEG C under the pressure of 0-2 KPa; adding the microelement solutions into the organic material liquid at the temperature of 60-80 DEG C; dissolving macroelements into the water at the temperature of 60-80 DEG C; adding the macroelements into the organic material liquid at the temperature of 40-60 DEG C; adding water to reach the formula proportion; uniformly stirring. The organic water-soluble fertilizer produced by using the method is high in mobility and stability, and the problems of separation by crystallization and gaseousness of products are solved.

Description

technical field [0001] The invention belongs to the technical field of crop fertilizers, and in particular relates to a preparation method of organic water-soluble fertilizers. 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. Using water and fertilizer at the same time, water and fertilizer are used to realize the integration of water and fertilizer. Its effective absorption rate is more than double that of ordinary chemical fertilizers, reaching 80% to 90%. Moreover, the fertilizer effect is fast, which can meet the nutritional needs of high-yielding crops during the ...
