Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of water-soluble fertilizers, and particularly relates to a hydronium ion water-soluble fertilizer and a preparation process thereof. Background Art
[0002] A hydronium ion refers to a substance formed by the attraction of a hydrogen ion by a water molecule, usually represented by H 3 O + ; in biological systems, the pH difference inside and outside cells is crucial for the normal function of cells, and the hydronium ion is a key factor in maintaining the pH balance inside and outside cells. Its generation and consumption can regulate the acid-base balance inside cells and maintain normal cell metabolic activities.
[0003] A water-soluble fertilizer refers to a liquid or solid fertilizer used for purposes such as water dissolution or dilution, foliar spraying, soilless cultivation, seed soaking and root dipping, drip and spray irrigation; it is a multi-component compound fertilizer that can be completely dissolved in water, can be quickly dissolved in water, is more easily absorbed by crops, and has a relatively high absorption utilization rate. More importantly, it can be applied to facility agriculture such as drip and spray irrigation to achieve the integration of water and fertilizer, and achieve the effects of water saving, fertilizer saving and labor saving.
[0004] Currently in the water-soluble fertilizer industry, only some conventional functional fertilizers indispensable to plants are used. Conventional fertilizers only focus on the absorption degree and nutrition of fertilizers, and never pay attention to the absorption and metabolic activities of cells in plants. The absorption of some weak acid-base fertilizers causes the pH imbalance inside and outside cells in plants. At the same time, the plant body can only adjust itself and cannot obtain regulatory substances from nature, resulting in metabolic disorders and affecting the normal growth of plants. Therefore, the present invention proposes a hydronium ion water-soluble fertilizer and a preparation process thereof to solve the problems existing in the prior art. Summary of the Invention
[0005] In view of the above problems, the object of the present invention is to provide a hydronium ion water-soluble fertilizer and a preparation process thereof. The hydronium ion water-soluble fertilizer and the preparation process thereof prepare a coated water-soluble fertilizer, mix the hydronium ion in a water-soluble coated state into the fertilizer, and provide a substance that can be absorbed from the outside and can regulate the pH balance inside and outside plant cells for plants during fertilization, reducing the nutrient consumption of self-synthesis, and improving the growth of the plant body in cooperation with the application of the fertilizer; at the same time, since the hydronium ion can participate in the acid-base neutralization reaction, its mixture with the fertilizer can be applied to neutralize the alkaline substances in the soil of saline-alkali land, so as to achieve the function of saline-alkali land treatment while fertilizing.
[0006] To achieve the object of the present invention, the present invention is realized through the following technical solutions: A hydrated hydrogen ion water-soluble fertilizer is prepared by wrapping a water-soluble composite powder fertilizer with hydrated hydrogen ion inclusion bodies. The hydrated hydrogen ions are prepared by dropping a sodium alginate mixed hydrated hydrogen ion solution into an L-calcium lactate aqueous solution. The water-soluble composite powder fertilizer is prepared by mixing a water-soluble fertilizer, organic manure, potassium dihydrogen phosphate, and rice husk ash.
[0007] Further improvement lies in that: the mass ratio of sodium alginate to the hydrated hydrogen ion aqueous solution is 95:5, the mass ratio of L-calcium lactate to deionized water in the L-calcium lactate aqueous solution is 90:10, and the mass ratio of the water-soluble fertilizer, organic manure, potassium dihydrogen phosphate, and rice husk ash is 30:40:10:20.
[0008] Further improvement lies in that: the water-soluble fertilizer is one of a solid water-soluble fertilizer and a liquid water-soluble fertilizer. The solid water-soluble fertilizer is one or more of a humic acid water-soluble fertilizer, an organic water-soluble fertilizer, and a trace element water-soluble fertilizer. The liquid water-soluble fertilizer is one or more of an amino acid-containing water-soluble fertilizer and a medium element water-soluble fertilizer.
[0009] A preparation process of a hydrated hydrogen ion water-soluble fertilizer includes the following steps:
[0010] Step 1. Treatment of organic manure and rice husk ash. First, carbonize the rice husk ash, then dry the organic manure and mix and stir it with the carbonized rice husk ash. Finally, grind the stirred mixture to obtain a mixed fertilizer powder.
[0011] Step 2. Preparation of the water-soluble composite powder fertilizer. Mix and stir the water-soluble fertilizer and potassium dihydrogen phosphate with the mixed fertilizer powder to obtain the water-soluble composite powder fertilizer.
[0012] Step 3. Preparation of the preparation solution. Add L-calcium lactate to deionized water and stir well for standby. Then prepare a hydrated hydrogen ion solution and mix it with sodium alginate powder to obtain a dilute colloidal solution for standby.
[0013] Step 4. Preparation of the inclusion body. Drop the dilute colloidal solution prepared in Step 3 into the L-calcium lactate aqueous solution by the dropping method to obtain granular hydrated hydrogen ion inclusion bodies.
[0014] Step 5. Outer packaging treatment. Pour the prepared granular hydrated hydrogen ion inclusion bodies into the water-soluble composite powder fertilizer prepared in Step 2 and shake until the outer surface is evenly covered with the water-soluble composite powder fertilizer, then sieve it out and perform drying treatment to obtain the hydrated hydrogen ion water-soluble fertilizer.
[0015] A further improvement lies in that: in step one, the rice husk ash is the residual solid obtained by burning rice husks in a negative oxygen ion environment, the organic manure is obtained by drying livestock manure after removing impurities, and after mixing, it is subjected to pulverization and grinding treatment to obtain a solid powder with a particle size of 50 - 500 nm.
[0016] A further improvement lies in that: in step three, the mass ratio of calcium L-lactate to deionized water is 90:10, and heating and stirring are carried out at 45 - 60 °C during mixing; when the hydronium ion solution is mixed with sodium alginate, rapid stirring and mixing are carried out at 60 - 70 °C, and the stirring speed is 180 r / min.
[0017] A further improvement lies in that: the specific preparation of the hydronium ion solution in step three is as follows:
[0018] S1. Mix a sulfuric acid solution with a concentration of 0.5 - 2 mol / L with diatomaceous earth in equal proportions, and add the mixed solution to a stirrer for stirring reaction;
[0019] S2. After the stirring reaction, let the mixed solution stand and precipitate for 12 h, then separate the precipitate and the supernatant, and then perform centrifugation on the supernatant to obtain a pure supernatant;
[0020] S3. Detect the sulfate ions in the pure supernatant. When the sulfate is less than 0.1%, it is a qualified hydronium ion solution.
[0021] A further improvement lies in that: in S1, the pH value of the sulfuric acid solution is less than 0.7, and the stirring reaction condition is to heat the stirrer to 55 °C and stir for 30 min; when the detected sulfate in S3 is greater than 0.1%, add an equal amount of diatomaceous earth to the obtained pure supernatant again, and then repeat the steps of S1 and S2 and then perform detection until the sulfate in the pure supernatant is less than 0.1% and the pH value is between 6 - 7.
[0022] A further improvement lies in that: when dropping the dilute colloidal solution into the calcium L-lactate aqueous solution in step four, the calcium L-lactate aqueous solution is cooled to room temperature while the dilute colloidal solution is kept at 40 - 50 °C after mixing for operation. After obtaining the inclusion body, fish it out from the calcium L-lactate aqueous solution and drain the water until it stops dripping.
[0023] A further improvement lies in that: in step five, first pour the outer package powder into a flat plate, then put the obtained inclusion body into the flat plate and spread it in a single layer, and then shake it so that the inclusion body rolls in the flat plate to make its surface adhere to a layer of outer package powder; the drying treatment condition is to carry out low-temperature drying at 40 - 60 °C to harden the surface.
[0024] The beneficial effects of the present invention are as follows: By preparing a wrapped water-soluble fertilizer, hydronium ions are mixed into the fertilizer in a water-soluble wrapped state, providing substances that can be absorbed from the outside by plants during fertilization and can regulate the pH balance inside and outside plant somatic cells, reducing the nutrient consumption of self-synthesis, and improving the growth of plants in combination with the application of fertilizers;
[0025] At the same time, since hydronium ions can participate in acid-base neutralization reactions, when they are mixed with fertilizers and applied, they can react with alkaline substances in the soil of saline-alkali land, so as to achieve the function of treating saline-alkali land while fertilizing.
