Abstract
The present invention relates to a composite secondary trace element cehalte fertilizer and its production method. In said invention, amino acid and humic acid are used as chelating agent to form secondary trace elemnt chelate so as to can effectively prevent adverse reaction between element and several ions and can greatly raise the utilization rate of secondary trace element fertilizer. Said ivnented secondary trace elements can be individually used, also can be mixed with N, P and K to produce complex fertilizer, also can be granulated, and use as raw material of blended fertilizer (BB fertilizer).
Description
The invention discloses a compound medium-trace element chelated fertilizer, and relates to the field of compound fertilizer production.
Macroelement N, P, K is well known as a three-element fertilizer and is the mainstay of the world's fertilizer industry. With the rapid increase of N, P, K fertilizer application amount, crops take away more and more medium and trace elements from soil, and the shortage of the medium and trace elements in the soil is getting worse. Areas lack of medium trace element soil are more and more, and the problem is more and more serious. Soil survey data in China show that most areas are deficient to different degrees. Therefore, the rapid and systematic supplement of the trace elements in the soil is an important problem of continuous yield increase of modern agriculture.
The production and use of medium and trace elements in China are paid attention by the agricultural science and technology department, various medium and trace element fertilizers are put into the market one after another, and a good yield increasing effect is achieved. However, most of the current medium and trace elements are inorganic salts, and the patent publication No. 89107147 uses a plurality of mineral powder and inorganic salts to prepare the multi-element trace element fertilizer. Due to antagonism and chemical reaction among elements and interaction of various ions in soil, most elements are fixed by soil through reaction, or inorganic salt which is difficult to dissolve in water is generated, and the elements cannot be absorbed and utilized by plants. The fertilizer production enterprises abroad chelate the medium and trace elements with chelating agents such as EDTA, citric acid and the like to mix the chelated medium and trace elements into the compound fertilizer, but the compound fertilizer is difficult to popularize in China due to high cost.
In order to obtain a low-cost and excellent-performance microelement chelate, a Chinese patent (application No. 95120857.8) introduces a mixed amino acid complex multi-element fertilizer and a manufacturing method thereof, provided that industrial wastewater containing amino acid is utilized. If such waste water is not available locally, the process cannot be industrially produced. The invention uses waste protein as raw material, after amino acid is generated by hydrolysis, oxide of trace element or inorganic salt is added to carry out chelation reaction, the generated strongly acidic amino acid trace element chelation liquid removes residual acid by water quenching slag, and simultaneously, active silicon fertilizer which is extremely beneficial to crops is generated. The reaction is as follows:
after the reaction, the material is slightly acidic, and then alkaline sodium humate is added to adjust the pH to 6-7, wherein part of H2SiO3Under alkaline condition, water-soluble Na is generated2SiO3。
Humic acid and Na2SiO3Generates a double salt which is more beneficial to the absorption and utilization of plants. Humic acid is used as a chelating agent to be further chelated with free amino acid to dissolve the free Ca, Mg and other trace elements, and finally, the compound medium trace element chelated fertilizer with the amino acid and the humic acid as the chelating agent and silicon fertilizer as a carrier is generated.
The embodiments of the present invention are as follows:
adding 100 parts of waste protein into an enamel reaction kettle, and adding 150-500 parts of 25-40% strong acid (HCl, H)2SO4、H3PO4) Hydrolyzing until protein is completely dissolved, adding trace elementsAnd (3) carrying out hydrolysis chelation reaction on the oxide or inorganic salt for 4-8 hours, spraying the chelated acid solution onto 2-10 times of water-quenched slag after the reaction is finished, stirring and mixing uniformly, standing and aging, adding alkaline sodium humate, stirring, standing, granulating and drying to obtain the granular medium and trace element fertilizer.
The process has the advantages that:
1.the amino acid is prepared by hydrolyzing the waste protein, and the hydrolyzed acid takes water quenching slag as a neutralizer to play a role of' one acid for two purposes, and two purposes are achieved, so that the production cost is effectively reduced.
2. Excessive acid is used during hydrolysis, so that the hydrolysis speed is high, the protein is thoroughly decomposed, and H is generated after the action of the acid and water quenching slag2SiO3The silicon fertilizer is activated, and the utilization rate of the silicon fertilizer is improved.
3. The humate produced by weathered coal is alkaline and just matches with the generated H2SiO3Reaction to form water-soluble Na2SiO3Continue to generate compound with humic acid, improve Na2SiO3The stability in soil can improve the fertilizer efficiency of humic acid.
4. Because a large amount of water quenching slag is used, the water quenching slag is not only a neutralizer of amino acid liquid, but also a carrier of medium and trace element fertilizer. The structure is loose after reaction, and the common drying equipment is easy to use for drying.
5. Because the medium trace elements are chelated, the fertilizer has stable performance, prevents the medium trace elements from being fixed by soil, prevents water and soil loss, is easy to be absorbed and utilized by plants, and has high fertilizer efficiency and low cost.
Example (b):
1000Kg of waste feather is added into a 5000L enamel reaction kettle, and 30% of H is added2SO43500Kg, hydrolyzing at 100-110 ℃ for 2 hours, adding Zn2SO4·7H2O300Kg，Fe2SO4·7H2O 250Kg，MnSO4·H2O 200Kg，Cu2SO4·5H2Continuously hydrolyzing for 4-6 hours under the condition of 50Kg of O to generate the acid amino acid trace elementsSpraying the hydrolysate onto 50 tons of water quenched slag, stirring, standing for 2 days, adding 5 tons of humate, standing for 1 day, and drying to obtain the product of the invention.
