Embodiment 1

[0024] Example 1: Put 20kg of sea-tangle into a 5% hydrochloric acid solution and soak for 24 hours, and stir the sea-tangle once every hour during the soaking. Rinse the soaked kelp with water until the pH of the water is 6.0-7.5.

[0025] Add 100L of clear water to the enzymatic hydrolysis tank, add papain 120U / g, under stirring, after it is completely dissolved, beat the treated kelp and pour it into the enzymatic hydrolysis tank, heat to 55°C, and keep warm for enzymatic hydrolysis After 2 hours, the stirring was stopped. Add 60L of 2% sodium carbonate solution and heat the temperature to 70°C. After 3 hours, the kelp will become a viscous paste. At this time, stop heating, perform cooling and filtration, and filter twice with a 250-mesh filter of a flat filter to obtain Clarify the sodium alginate solution. Then add 3% hydrochloric acid solution to adjust the pH value of the solution to 7.5. Then filter to remove impurities, and concentrate to obtain an alginic acid so...

Embodiment 2

[0027] Example 2: Put 20kg of kelp into a 3% hydrochloric acid solution and soak for 28 hours, and stir the kelp every 1 hour during the soaking period. Rinse the soaked kelp with water until the pH of the water is 6.0-7.5.

[0028] Add 120L of clear water to the enzymatic hydrolysis tank, add pectinase 80U / g, under the condition of stirring, after it is completely dissolved, beat the processed kelp and add it to the enzymatic hydrolysis tank, heat to 60°C, keep warm for 1.5 hour, stop stirring. Add 60L of 4% sodium carbonate solution and heat the temperature to 75°C. After about 3 hours, the kelp will become a viscous paste. At this time, stop heating and perform cooling and filtration. Filter twice with a 250-mesh filter of a flat filter. A clear sodium alginate solution was obtained. Then add 5% hydrochloric acid solution to adjust the pH value of the solution to 7.0. Then filter to remove impurities, and concentrate to obtain an alginic acid solution with an alginic aci...

Abstract

The invention provides a synergistic compound fertilizer and a production method thereof. The production method comprises the following steps: firstly producing an alginic acid solution through an enzymatic hydrolysis method, mixing the alginic acid solution with inorganic raw materials according to a certain proportion, granulating through a high tower, and drying by a drum drying machine so as to get a finished product. The content of alginic acid in the product, namely a compound fertilizer synergist provided by the invention is 0.3%-20%, and the total content (calculated by N, P2O5 and K2O) of the inorganic nutrients is 25%-80%. The synergistic compound fertilizer provided by the method disclosed by the invention can significantly improve the quality of crops, is conductive to growth of root systems of the crops and has an important significance in the aspects of improving an ecological environment of farmland, easing the disproportionality of the fertilizer and the like.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizer production, in particular to a production method of synergistic compound fertilizer. Background technique [0002] At present, the situation of soil fertilization in our country is more focused on the input of chemical fertilizers, but the utilization rate of chemical fertilizers has not been improved. Due to excessive and blind increase in the use of chemical fertilizers, the utilization rate of chemical fertilizers has a tendency to decline. my country accounts for 10% of the world's arable land but consumes 30% of the world's chemical fertilizers. The amount of chemical fertilizer input per unit of arable land is 2.8 times the world's average amount. The low utilization rate of fertilizers and the intensification of soil-borne diseases and insect pests have caused serious environmental pollution and a decline in the quality of agricultural products, threatening national food securit...
