Description

Method for preparing a fertilizer containing amino acids with water-soluble silicic acid

The present invention relates to a fertilizer and a method for producing the same, and more particularly, to an organic fertilizer containing an amino acid bonded to a water-soluble silicic acid and a method for producing the same. In particular, the present invention relates to a liquid fertilizer containing an amino acid in which water-soluble silicic acid is bound, which is small in particle size, and has excellent water absorption of crops, which enables foliar spreading, and a method for producing the same.

Silicon (Si) is the second most abundant element of the earth's crust. Such silicon is present in the form of silicic acid [Si (OH) ₄ ] in the soil solution below pH 9 and in the form of silicic acid ions above, it is known that the adsorption is best in the soil at pH 9.5. At present, the concentration of silicon in our soil is SiO ₂ When calculated by content, it is investigated that it is about 7-80 mg / kg.

The degree of silicon uptake by higher plants is very different depending on the type of plant. In the case of aquatic plants and plants such as rice and genus, they absorb and accumulate a very large amount of silicon, which is about 10 to 15% in dry matter, and about 1 to 3% in grain crops grown in fields such as sugar cane. It appears to contain. In addition, silicon content in dicotyledonous plants, such as soybean, is 0.5% or less, and gourds such as cucumbers, melons, watermelons, melons, and pumpkins are known to absorb much silicon.

When silicic acid is absorbed by the plant, the leaves and stems do not collapse and fall well, so that the lower leaves of the plant receive a lot of sunlight, and carbon assimilation is active. In addition, the silicic acid component enters the plant to form a silicic acid layer (cuticula layer) on the cell wall and strengthens the cells, thereby increasing resistance to diseases such as heat diseases, catabolism, and rice worms. It increases resistance to bacterial and viral diseases as well as cold and cold. In addition, silicic acid not only promotes growth, but also regulates soil improvement and fertilizer effects to prevent excess nitrogen and phosphate absorption disorders, maintains the freshness of plants, improves shelf life, and greatly increases the hardness and sugar content of fruits. .

Silica fertilizers currently supplied are soluble siliceous fertilizers made of steel slag as raw materials, and are divided into two types, powder and granular. However, almost insoluble substances are absorbed by plants at 0.002% per year. Since the remainder is accumulated in the soil, there is a problem in that a large amount of continuous spraying within a certain period.

In addition, the existing siliceous fertilizer puts enormous burden on the transportation and fertilization of the farmers as users, and the effectiveness of the silicate fertilizer is greatly reduced due to the large number of harmful substances and foreign substances, and the fertilization period is only possible at the first stage of fertilization. I could not cope.

In addition, the conventional siliceous fertilizer is prepared in the form of a solid powder having a large particle size of the silicate particles several micrometers. Therefore, when directly sprayed on the leaf surface is not only high absorption rate, but also in the case of liquid silicon had a problem that must be effectively attached to the leaf surface. In addition, conventional siliceous fertilizers are mostly transmitted through the soil, and gradually solubilized by organic acids in the soil or acids secreted from crop roots, and then absorbed and used by plants. However, since the active ingredient of the siliceous fertilizer is poorly soluble in water, there is a problem of low absorption efficiency. In addition, the absorption of silicic acid in plants has a problem that the ratio of silicon (Si) / aluminum (Al) or silicon (Si) / iron (Fe) in the soil must be increased because of the passive characteristics affected by the proportion of the type. .

Moreover, it is to spray these siliceous fertilizer directly to the soil, there is a problem that interferes with even a small amount of silicic acid when dissolved, seamless silicate absorption of the plant because they form an aluminum (Al ^{3 +)} and a complex present in the soil in the soil.

On the other hand, when the previously produced silicic acid and amino acid are mixed, it is difficult to use crop foliar fertilization and irrigation fertilization, and the crop is not easily absorbed and used. In order to improve this problem, the condensed particles must be filtered. There was a problem of raw material loss.

As a result of research for solving the above problems, the present inventors have completed the present invention by developing a liquid fertilizer containing silicic acid-bound amino acid and a method for producing the same.

An object of the present invention is a method for producing a liquid fertilizer containing a water-soluble silicic acid-containing liquid fertilizer and a water-soluble silicic acid is small particles and excellent absorption of crops so that the crops can be directly sprayed on the foliar to absorb the silicon directly It is to provide a liquid fertilizer containing amino acids.

In order to achieve the above object, the present invention comprises a first step of mixing a predetermined silicate containing silicon (Si) in the reactor with a slaughtered by-product or soybean containing a large amount of amino acid raw material; Adding a water, silicate and electrolyte to the mixture in the reactor and applying an electrical force to raise the pH to 11 or more; A third step of increasing temperature and pressure while applying electric force; And a fourth step of homogenizing the reacted material into nm-sized particles using an in-line homomixer.

The process of the invention dissolves slaughter by-products and the silicic acid to amino acids produced by mixing the protein source, such as slaughter by-products, with silicates and electrolytes and appropriately adjusting the pH, temperature and pressure of the mixture while applying electrical force to the mixture. The organic liquid fertilizer containing the amino acid to which silicic acid was couple | bonded by producing a bond is produced.

The present inventors in the existing method for making amino acids using animal hair or soybeans, when the silicate is added and reacted when applying an electric force to hydrolyze the protein, the silicate is combined with the amino acid in this case inline rotating at high speed The present invention has been completed by discovering that passing through a mixer makes it possible to produce fertilizers containing amino acids bound to nanoparticle sized water-soluble silicic acids.

As the electrolyte used in the method of the present invention, NaOH or KOH may be used, and the silicate is not particularly limited, and the amount of the silicate and the electrolyte is preferably 5-30 wt% and 1-12 wt%, respectively. In addition, in the second step of the method of the present invention, the pH is more preferably raised to 12 or more, and in the third step, the reactor temperature is increased to 150 ° C to 200 ° C, preferably 160 ° C to 180 ° C, and The pressure is increased to 6-8 kg / cm 3, and the electrical force can be applied using, for example, a (+), (-) titanium electrode or a carbon electrode.

In the present invention, the slaughter by-products or soybeans in the mixture are supplied by applying an electrical force to the solution (electrolyte) or after the supply by applying an electrical force directly and raising the temperature and pressure to cut and dissolve to produce amino acids.

The amino acid has both -COOH and -NH ₂ groups which are alkaline. Therefore, the amino acid is called an amphoteric electrolyte, and depending on the pH of the solution, the amino acid may act as an acid or an alkali. On the other hand, when the amino acid is completely neutral in aqueous solution, the pH at this time is called the isoelectric point. This isoelectric point is used to separate each unique amino acid from a protein. The following structural formulas show general molecular structural formulas of amino acids, and classify amino acid types according to the type and isoelectric point of the R group.

Increasing the reactor temperature along with the electrical force in the reactor and increasing the pressure in the reactor to 6-8 kg / cm 2, SiO ₃ is bonded to the R-based structure of the amino acid produced by the dissolution of the slaughter by-products, resulting in the amino acid having water-soluble silicic acid You can get it.

When applying an electric force as in the present invention, the action mechanism is as follows.

2SiO ₂ + 5H ₂ O + E → 2SiO ₃ + OH + OH + 1 / 2O ₂ + 4H ₂

For example, if silicate and a small amount of KOH are added and the electric force is applied using the (+) and (-) titanium electrodes, OH ⁻ ions among the coexisting ions such as 2KOH → OH + OH + 2K ^{+ are} converted into OH + E ( Electrical energy) → OH (activation) to radical ions. Oxygen gas at the positive electrode and hydrogen gas at the negative electrode increase the pressure of the reactor to several μm, and SiO ₃ is bonded to the R group of the amino acid under the increased pressure.

In particular, when an electric force is applied at 12V, 1.5A, 0.054A / cm 2 with a DC power source, the charge is transferred as follows to promote the activation of the OH group.

      Coulomb number of charges = Amps × seconds = C / s × s

                     = 1.5 C / s × 30.0 min × 60 s / min

                     = 2,700 C

2,700 C × 1 mole e- / 96,846 C = 0.002788 mole e-

According to the present invention, a manufacturing apparatus for producing an organic fertilizer containing an amino acid in which silicic acid is bound using animal hair or soybean and silicate includes a conventional reactor, a homomixer, etc., which is equipped with an electrolysis device and can be heated and pressurized. It can be configured as. As illustrated in FIG. 1, the preferred reactor may include titanium electrodes 111 and 112, agitator 120, and the like, but the configuration of the reactor is not limited thereto. 2 shows an example of a preferred manufacturing apparatus.

In the present invention, the slaughtered by-product means, for example, hair, epidermis, blood, nails, toenails, horns, or the like, which contains a large amount of animal protein obtained from an animal.

By-products obtained from animals, in particular livestock, are generally discarded with the exception of very few parts, such as chicken feet. In the present invention, by-products obtained from such animals can easily produce organic fertilizers containing silicic acid bound amino acids.

For example, animal hair is a high concentration of protein, about 74% of the protein, and 43% of the soybean protein, which is useful for the production of fertilizers containing high-quality amino acids. In the present invention, as slaughter by-products, particularly preferably animal hair is used.

Since hydrolyzing proteins becomes amino acids, organic fertilizers prepared by decomposing slaughter by-products or soybeans as raw materials according to the present invention not only contain a large amount of various amino acids, but also contain amino acids in which silicic acid is bound, and thus can be used as an effective fertilizer. .

Chemical fertilizer is decomposed and converted into nitrogen nitrate to nitric acid, nitric acid is decomposed to ammonia, and ammonia is amino acid, so the crop is absorbed, so fertilizer loss is large and absorption by the crop is delayed, causing soil acidification.

Hereinafter, the present invention will be described in more detail with reference to Examples. It is to be understood by those skilled in the art that these embodiments are for illustrative purpose only and that the scope of the present invention is not limited to these embodiments.

Example  1. Silicate Combined  Preparation and Analysis of Fertilizers Containing Amino Acids

Fertilizer was prepared according to the method of the present invention using the following composition and conditions.

Wool: 1 kg

Water: 350g

Silicate: 100 g

Potassium hydroxide: 50 g

Reactor temperature: 168 ℃

Reactor pressure: 6.5 kg

Reaction time: 1 hour

As a result of analyzing the amino acid of the prepared sample, the result was that the amino acid content was 12.7% as shown in Table 1 below.

Example  2. Crop Test

When ions pass through the membrane by diffusion, they do not pass through the lipid layer of the membrane with water, especially in a charged state. However, it can be absorbed through the protein pathway of the plant cell membrane, which is the protein of the pathway becomes a carrier (carrier) and is absorbed through it, and this is called Facilitated diffusion. This accelerated diffusion, like simple diffusion, is passive transport, and the required energy is derived from the electrochemical gradient and has no direct correlation with the energy produced by metabolism.

When the amino acid is sprayed on the foliar surface, it temporarily serves as a protein pathway, and by facilitating diffusion, the water-soluble silicic acid is transported into the plant by the electrochemical potential difference. To demonstrate this effect, empirical crop tests were conducted.

When fertilizer containing amino acid conjugated with water-soluble silicate prepared according to the present invention was applied to crops, the sugar content was increased by 12.7% by 1.3 brix increase and 27% by hardness increased by 0.06 kgf when fertilized with 500 times the amount of strawberry. (Table 3), rice was improved by 10.1% when fertilized with 500 times liquid, and yield was increased by 12.9% by increasing 71kg / 10a (Table 4).

In addition, as a result of measuring the silicon content of the rice straw used in the test to determine the silicic acid utilization when using the liquid ratio prepared according to the present invention, it was found that the silicon content in the rice straw is 16.6% at 500 times and 11.4% at 1000 times. (Table 5).
