Embodiment 1

[0070] Production Example 1: 300kg of 50% potassium hydroxide solution was added to the reactor. Add 225kg of citric acid into potassium hydroxide solution for neutralization reaction, and add 0.5kg of M-10 dispersant, and stir at 75°C for 45 minutes. To the end of the neutralization reaction, the pH value reaches 7-8. When the temperature reaches 65-70°C, add 30kg of boric acid. When the pH reaches 10-11, 15 kg of zinc oxide is added, stirred and reacted for 30 minutes, and the complexation reaction is carried out. Add 200kg 50% biochemical fulvic acid, and stir for 30 minutes. Add 4kg of nitrate-naphthalene mixture and stir for 15 to 20 minutes. Add 75kg of potassium nitrate or potassium dihydrogen phosphate, stir and cool to room temperature. Measure PH=7~8, obtain liquid organic compound fertilizer. Canning: Pump into finished product storage tanks.

Embodiment 2

[0071] Production Example 2: 150kg of 30% biochemical fulvic acid solution was added to the reactor. Slowly add 148kg of industrial potassium hydroxide under stirring. The temperature in the reactor is controlled below 50°C through the feeding speed and jacket cooling water temperature. Slowly add 200kg of citric acid to carry out the neutralization reaction, the temperature is controlled at 75°C, and the reaction is stirred for 45 minutes. When the temperature reaches 65-70°C, add 40kg of boric acid, 80kg of powdered urea or glucose, and stir for complexation reaction. Naturally cool down to room temperature, add 3.2kg of nitrate-naphthalene mixture, and stir for 30 minutes. Measure PH=6~8, get liquid high-concentration organic boron potassium fertilizer. Pump into finished product storage tank.

Abstract

The present invention is one kind of organic potash fertilizer produced with composite organic acids and its production process. The production process includes feeding potassium hydroxide and fulvic acid solution into reaction kettle, adding organic acid to produce neutralization reaction, adding trace elements to produce complexing reaction, adding assistants and / or macro elements, cooling and packing. The present invention has the advantages of low cost and easy control of production conditions, and the product has high organic matter content, high activity, high nutrient content and superposed function of organic acids.

Description

technical field [0001] The invention relates to an organic potash fertilizer and a production method thereof, in particular to a liquid organic potash fertilizer made from a compound organic acid and a production method thereof. Background technique [0002] Organic liquid fertilizers, which are widely used mainly include humic acid liquid fertilizers containing fulvic acid, amino acid liquid fertilizers, and organic liquid fertilizers produced by active organic matter extracted from marine organisms. This type of organic liquid fertilizer is mainly the product of complexation or neutralization reaction of organic acids such as humic acid, amino acid or alginic acid and trace elements and macroelements. [0003] Active organic substances extracted from marine organisms, such as alginic acid extracted from seaweed, generally have low active ingredient content and high prices. [0004] Amino acid liquid fertilizer used as foliar fertilizer or flushing fertilizer, its amino ac...
