Description

Technical Field [0001] The present invention relates to a method for producing a calcium phosphate fertilizer containing a flavonoid of Rhus verniciflua,

The present invention relates to a method for preparing a calcium-containing calcium-fertilizer containing flavonoids of Rhus verniciflua, and more particularly, to a method for producing calcium-containing calcium-fertilizers in which flavonoids extracted from Rhus verniciflua are uniformly bound to calcium alginate.

Since the symptoms of calcium deficiency in crops and the pathologies caused by bacteria and viruses are very similar, it is necessary for growers to take appropriate measures considering their possibilities.

Calcium protects crops against external toxins and plays an important role in cytoplasm and cell wall formation. In addition, since flavonoids have antibiotic, antiviral, anticancer, anti-allergic and anti-inflammatory activities, they play an important role in preventing and alleviating the disease in crops.

Therefore, supplying calcium antibiotic flavonoid to the crops has a synergistic effect in preventing crops from being attacked by outside, and preventing bacterial and viral infection.

In recent years, flavonoids contained in Rhus verniciflua have attracted attention as natural extracts excellent in antibacterial and antiviral properties, and Korean Patent No. 10-1239400 and others disclose a method of extracting Rhus verniciflua extract having a high flavonoid content.

However, there is no known fertilizer composition in which calcium and flavonoid are combined so that calcium and an antimicrobial flavonoid can be simultaneously administered to crops.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a method for producing a calcium-containing calcium phosphate fertilizer in which calcium and a natural flavonoid component are uniformly combined so as to be useful in agriculture.

A method for producing a powdered calcium fertilizer containing a lacquer flavonoid according to the present invention comprises the steps of: 1) stirring a mixture obtained by adding acetic acid to a sumac tree heated to 35 to 45 캜 and stirring the mixture; A third step of adding calcium carbonate to the liquid material obtained in the second step to neutralize the liquid material, a fourth step of fermenting the liquid material which has gone through the third step, A fifth step of concentrating the liquid material fermented in the step, and a sixth step of pulverizing the liquid material concentrated in the fifth step by using a spray dryer.

In addition, the present invention is characterized in that in the fourth step, wheat blooms are added for fermentation, fermented at room temperature for 10 days, and the fermented liquid material is filtered using a filter press.

Hereinafter, the contents of the invention for carrying out the present invention will be described in more detail.

Referring to FIG. 1, a method for preparing a powdered calcium fertilizer containing a lacquer flavonoid according to the present invention is sequentially carried out according to the following process.

(a) a first step (step S10) in which a mixture obtained by adding acetic acid to a sumac sap is heated to 35 to 45 캜 and stirred,

(b) a second step (S20) of adding a mixture obtained through the first step to a filter press to obtain a liquid product by filtration,

(c) a third step (S30) in which calcium carbonate is added to the liquid material obtained in the second step to carry out a neutralization reaction;

(d) a fourth step (S40) of fermenting the liquid material through the third step;

(e) a fifth step (S50) of concentrating the fermented liquid material in the fourth step,

(f) a sixth step (S60) of pulverizing the concentrated liquid material in the fifth step using a spray dryer,

In the first step, in order to extract a flavonoid component from Rhus verniciflua varnish, acetic acid is added to a mixture of Rhus verniciflua and the mixture is heated to 35 to 45 ° C and stirred.

Acetic acid is added to 100 kg of lacquer at a rate of 500 L of acetic acid, and the mixture is heated to 35 to 45 캜, preferably to 40 캜. In the warmed state, the stirring process is performed using a stirrer, and stirring time is 40 to 50 hours, most preferably, stirring is performed at 40 DEG C for 48 hours.

The acetic acid added in the process serves not only to extract flavonoid components from Rhus verniciflua but also to produce water-soluble calcium in a subsequent step.

When the first step is completed, the active ingredient including flavonoid component in the lacquer tree is dissolved in the acetic acid, and cellulose and the like of the lacquer tree are left in the residue. The second step of removing the debris from the mixture of the first step and filtering by a filter press to obtain a liquid product is carried out.

The filter press is a pressurized filter, and only the liquid material can be obtained from the mixture by putting the mixture in a filter cloth (filter cloth) and compressing.

Thereafter, the third step in which calcium carbonate is added to the filtered liquid material in the second step to perform the neutralization reaction proceeds. At this time, the calcium carbonate and the acetic acid are added at a weight ratio of 100.09: 120.1 so that a complete neutralization reaction can be performed. The weight of acetic acid is the weight of acetic acid added to Rhus verniciflua in the first step.

By the neutralization reaction, the hydrogen ion of acetic acid and the hydroxide ion of calcium carbonate are combined to form water, and the acid group, which is an anion of an acid, and the metal ion, which is a cation of a base, are combined to form a salt.

The chemical reaction in the third step in which calcium carbonate is added and neutralized is as follows.

_{2 (CH 3 COOH) + CaCO} 3 → Ca (CH 3 COO) 2 + H 2 O + CO 2

Accordingly, water-insoluble calcium can be provided as water-soluble calcium easily absorbed by binding to organic acids.

Acetic acid reacting with calcium carbonate plays a role of extracting the flavonoid component of Rhus verniciflua in the first step and then reacting with calcium carbonate in the second step to form water-soluble calcium.

The neutralization reaction is preferably carried out in the second step to accelerate the chemical reaction, and the neutralized reaction product is filtered using a filter press.

Thereafter, since the urushiol component is contained in the liquid material from which the component of Rhus verniciflua is extracted, the fourth step for removing the urushiol component proceeds.

Uruciol is a derivative of catechol compounds that does not show direct toxicity to the human body, but when contacted with the skin, it activates the immune system by reacting with external chemicals in the cell, causing dermatitis, so it needs to be removed.

The fourth step is a fermentation process in which wheat blooms are added for fermentation and fermented for 1 to 2 weeks. It is most preferable to ferment at room temperature for 10 days.

Ginseng roots, Angelica gigas, licorice root, and the like can be further added for fermentation, and the active ingredient contained therein is extracted and mixed as a fertilizer component.

The enzymes produced by the fermenting bacteria during the long fermentation process can be largely eliminated by biologically transforming urushiol.

After the fermentation, the fermented liquid material is filtered using a filter press in order to remove debris such as wheat blooms.

On the other hand, after the fermentation is completed, the fifth step of concentrating the fermented liquid material proceeds.

In the fifth step, the pressure is reduced so that the boiling point is lowered, and then the water is evaporated by heating at less than 100 ° C, preferably 60 ° C, to concentrate.

In the subsequent six steps, the concentrated liquid material is pulverized in the fifth step. By spraying in a high-temperature atmosphere using a spray dryer, moisture can be removed and a crystallized powder can be obtained.

Each crystal grain of calcium acetate forming the powder is adsorbed by the flavonoid and physically bonded to each other.

Preparation of Calcium Fertilizer According to Examples

2 (b) is a photograph of the calcium fertilizer powder produced by the manufacturing method according to the embodiment of the present invention.

For the production, the lacquer tree was pulverized to form a chip, and 5 kg of acetic acid was added to 1 kg of lacquer tree and the mixture was stirred at 40 캜 for 48 hours. Then, 4.37 Kg of calcium carbonate was added to the liquid product filtered by a filter press, stirred, and then filtered by a filter press.

To the filtered liquid was added 300 g of wheat flour, fermented in a tank for 10 days, filtered to extract only fermented liquid, and the extracted liquid was concentrated by heating under reduced pressure.

The concentrated liquid material was pulverized using a spray dryer to prepare a pulverulent calcium fertilizer according to the present invention.

2 (a) is a photograph of a typical calcium acetate.

Comparing the powders of (a) and (b) of FIG. 2, the calcium fertilizer produced by the manufacturing method according to the embodiment of the present invention has a dark brown color in the whole powders and has a chromaticity different from that of calcium acetate. It can be confirmed that the extracted polycarbonate component is physically bonded to each crystal grain of calcium acetate.

Compared with the mixture of lacquer extract and calcium acetate and the calcium fertilizer solution according to the examples

Fig. 3 (a) is a mixed solution obtained by simply mixing and stirring 100 ml of RVOX extract, 100 g of calcium acetate and 200 ml of water, and collecting a part thereof as a sample.

FIG. 3 (b) is a dissolving solution obtained by dissolving 200 g of powdery calcium fertilizer containing flavonoids of Rhus verniciflua according to an embodiment of the present invention in 200 ml of water, and a part of the powder is collected as a sample.

Fig. 4 is a photograph showing the occurrence of precipitates in the solutions after about 30 minutes and after (a) and (b) of Fig. 3.

As shown in FIG. 4 (b), the solution of the fractionated calcium fertilizer containing the flavonoid of Rhus verniciflua according to the above example shows a uniform dissolution state with the lapse of time.

4 (a), in the case of a mixed solution obtained by simply mixing the lacquer extract and calcium acetate, the precipitate layer 10 of the lacquer extract is formed at the lowermost portion, and the precipitate layer 20 of calcium acetate And a solution 30 in which the extract of lacquer and calcium acetate are dissolved in water is located on the upper side thereof.

In view of the above test results, the powdered calcium fertilizer containing flavonoids of Rhus verniciflua according to the above example was dissolved in water at the field to be fertilized in the crops, and during the fertilization operation, a uniform solution state Can be maintained for a long time, so that a constant ratio of calcium and flavonoid can always be administered to the crop, and the fertilizing effect can be uniformly obtained throughout the crop.

However, when a mixed solution obtained by simply mixing a lacquer extract and calcium acetate is added to a crop, it is impossible to form a state in which two components are uniformly mixed. Therefore, in the process of fertilization in the field, , There is a high risk of being administered to the crop at a non-uniform rate, and the effect of fertilization will be uneven throughout.

In addition, since the powdery calcium fertilizer containing the flavonoid of Rhus verniciflua according to the present invention is physically bonded to the calcium crystal powder to form a certain ratio in the whole powder even if it is directly added to the crop in the form of powder, Since a constant proportion of calcium and flavonoids can always be administered to the crop at the same time, it can simplify the fertilization process, make the fertilization effect uniform throughout the crop, and improve the utility of the fertilizer.
