DETAILED DESCRIPTION

[0024] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0025] In the description of the present invention, it should be understood that “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0026] See also Figure 9 The present invention provides a mixed dissolution method for producing a three-element all-effective high-concentration liquid fertilizer with slow release, comprising the following steps: S1: Add the specified raw materials and water into the dissolution equipment for water dissolution to prepare a turbid liquid with a specified ratio.

[0027] Specifically, at normal temperature and pressure, water is added to the mixed dissolving device, and then the raw material fertilizer-grade ammonium phosphate is made into a 50% turbid liquid, and the time is controlled until the ammonium phosphate is completely dissolved into a suspension; The raw material ammonium phosphate used in this process can also be fertilizer-grade diammonium phosphate or monoammonium phosphate, depending on the demand for phosphorus in the final product; If the final product requires high nitrogen, some nitrogen-containing fertilizers such as ammonium nitrate, urea, ammonium polyphosphate, etc. can be added.

[0028] S2: Add a specified chelating agent to the above turbid solution to obtain a corresponding clarified solution.

[0029] Specifically, the designated raw materials are fertilizer-grade monoammonium phosphate, diammonium phosphate, heavy calcium phosphate, ordinary calcium phosphate, calcium magnesium phosphate, etc. produced by wet-process phosphoric acid; the designated chelating agent is the chelating agent produced by Yunnan Leadford Technology Co., Ltd.; a potassium phosphate chelating agent with a concentration of 50% is added to the above-mentioned turbid liquid, and through chelation, the turbid liquid containing 14-16% of solid insoluble matter (such as Ca, Mg, Si, S, Fe, Zn, etc.) is chelated into a water-soluble complex. The complex will be the medium and trace nutrient components in the final product, and the amount of the chelating agent used accounts for 65-75% of the weight of the raw material, depending on the solid water-insoluble matter in the raw material.

[0030] Potassium phosphate chelating agent has extremely high complexing property for alkali metal ions. The dosage of phosphate chelating agent makes the suspension reach the requirement range of GB water-insoluble matter of 3.0-5.0% and contain clarified liquid. The clarified liquid contains potassium polyphosphate. It takes 10-30 days for potassium polyphosphate to hydrolyze into phosphate, forming the sustained-release property of the final product.

[0031] S3: adjusting the pH value of the clarified liquid so that the pH value of the clarified liquid after adjustment in a 1.0% aqueous solution is in a range of 1.5 to 2.3.

[0032] Specifically, an acid is added to the above clarified liquid to adjust the pH value of the clarified liquid to 1.5-2.0 (1.0% aqueous solution); The acid can be nitric acid, sulfuric acid and citric acid. If nitric acid is used, the final product is nitro liquid fertilizer. If sulfuric acid is used, the final product is sulfur-based liquid fertilizer. The added acid can be a single acid or a mixed acid of multiple acids. At the same time, citric acid can also be added. Citric acid is an organic acid that can regulate soil pH for plants, promote plant root growth, enhance plant resistance, and promote photosynthesis.

[0033] S4: After the pH value is adjusted, add alkali solution to the clarified liquid for neutralization to obtain a neutralized solution with a pH between 6 and 7. This neutralized solution is the ternary all-effect slow-release liquid fertilizer of the specified concentration.

[0034] Specifically, slowly pour the prepared 50% potassium hydroxide / potassium carbonate solution into the clarified liquid for neutralization. The amount of alkali solution is enough to control the pH of the neutralized liquid between 6-7. The neutralized liquid with a pH between 6-7 is a 50% concentration of ternary full-effect slow-release liquid fertilizer.

[0035] When the pH value of liquid fertilizer is low, the P205 of the liquid fertilizer is high; when the pH value is high, the KO2 of the liquid fertilizer is high. In this process, the N component is a fixed value, and the change in pH value plays a role in adjusting the P:K ratio of the liquid fertilizer.

[0036] Furthermore, in order to reduce costs, fertilizer-grade phosphoric acid is used, and a phosphate chelating agent is used to complex the fertilizer ammonium phosphate containing 14-16% of solid insoluble matter (such as Ca, Mg, Si, S, Fe, Zn, etc.), and then nitric acid or sulfuric acid is added to lower the pH value, and then potassium hydroxide or potassium carbonate, and potassium nitrate or potassium sulfate are added to neutralize to 6-7, and N=50-150mg / l, P205=200-650mg / l, KO2=200-550mg / l series of liquids can be obtained. The concentration of the liquid is adjusted, and a certain amount of neutral ammonium polyphosphate and potassium polyphosphate are added to form a slow-release liquid fertilizer. The final mixed liquid forms a high-concentration liquid fertilizer with a slow-release nitrogen + phosphorus + potassium + TE content greater than or equal to 600ml / L.

[0037] Further, specific embodiment 1: 40g fertilizer-grade diammonium phosphate is dissolved in 80ml water, melted and stirred to form a suspension. 26g of chelating agent is added to the suspension, stirred to clarify, 20g of nitric acid is added to the clarified liquid, and the concentration of nitric acid is 65%. At this time, the pH of the clarified liquid is 2.25. 40g of potassium hydroxide is made into a 50% aqueous solution, gradually added to the clarified liquid, and stirred to form a relatively concentrated 150ml liquid fertilizer. This is a nitro-low nitrogen, high phosphorus and potassium slow-release all-effective liquid fertilizer. The final analysis results are: pH=6.8, N:P:K+TE=80:650:550 (mg / l), TE=Ca, Mg, Si, S, Fe, Zn, etc., water-insoluble matter ≦1.0%; The obtained nitro-based low-nitrogen, high-phosphorus and potassium all-effect liquid fertilizer is suitable for calcium-loving plants growing on calcareous soils with a high pH value, such as corn and most vegetables, cotton, tobacco, fruit trees and other economic crops; Specific embodiment 2: Based on the same amount of clarified liquid obtained in Example 1, 20g of sulfuric acid was added to the clarified liquid, and the sulfuric acid concentration was 65%. At this time, the clarified liquid had a pH of 2.15. 47g of potassium hydroxide was made into a 50% aqueous solution, which was gradually added to the clarified liquid and stirred. During stirring, 5g of ammonium polyphosphate was added to finally form a relatively concentrated 150ml liquid fertilizer, which is a sulfur-based medium-nitrogen, high-phosphorus and potassium-releasing slow-release all-effect liquid fertilizer. The final analysis results are as follows: pH=6.8, N:P:K=100:600:600 (mg / l), TE=Ca, Mg, Si, S, Fe, Zn, etc., and water-insoluble matter ≦1.0%; the obtained product is a sulfur-based low-nitrogen, high-phosphorus and potassium all-effect liquid fertilizer, which is suitable for base fertilizer, topdressing, seed fertilizer and topdressing in various soils and various types of crops. Specific embodiment 3: 60g fertilizer-grade diammonium phosphate is dissolved in 80ml water, melted and stirred to form a suspension. 30g potassium phosphate chelating agent is added to the suspension and melted and stirred to clarify. 15g sulfuric acid, 10g nitric acid and 6g citric acid are added to the clarified liquid. The sulfuric acid concentration is 65%, the citric acid content is 98%, and the nitric acid concentration is 65%. At this time, the pH of the clarified liquid is 1.93. 50g potassium hydroxide is made into a 50% aqueous solution, which is gradually added to the clarified liquid and stirred. 5g ammonium polyphosphate is added during stirring to finally form a relatively concentrated 180ml liquid fertilizer. This is an organic nitric-sulfur-based low-nitrogen, high-potassium-phosphorus slow-release fertilizer with full-effect liquid fertilizer. The final analysis results are: pH=6.8, N:P:K=70:600:650 (mg / l), TE=Ca, Mg, Si, S, Fe, Zn, etc., and water-insoluble matter ≦1.0%; Organic nitro-sulfur based low nitrogen high potassium phosphorus slow release fertilizer all-effect liquid fertilizer, combining the advantages of nitro-sulfur based fertilizers, is adaptable to various soils and crops, and is drought-resistant, disease-resistant, cold-resistant, and can significantly improve photosynthesis efficiency.
