Horticulture fertilizer and its manufacturing method {FERTILIZER FOR GARDEN PLANT AND MANUFACTURING METHOD THEREOF}

The present invention relates to a horticultural fertilizer and a method for producing the same, which are capable of harvesting crops containing organic selenium which is beneficial to the growth of crops, resistant to pests, and beneficial to the human body, and more particularly, to the stevia extract, It relates to a horticultural fertilizer and its manufacturing method characterized in that it is included.

In general, fertilizers widely used in crops are nitrogen, phosphorus, potassium as a main ingredient, and if necessary, calcium, magnesium and other micronutrients containing synthetic micronutrients. These fertilizers properly distribute the nutrients needed by the crops, which makes the crops grow, improve the crop quality, and increase the yield. However, the problem that the continuous application of these chemical fertilizers to the soil can be acidified and ruined.

If crops like fruit are required to have a proper sugar content, they can increase the sugar content of the crop or decompose hydrogen peroxide in the body to prevent cell damage and prevent red blood cell breakage. In order to increase the competitiveness of farmers by producing more value-added crops, existing chemical fertilizers cannot achieve this purpose.

The present invention for solving this problem does not decompose the soil at all without increasing the growth of useful microorganisms in the soil to improve the adhesion of the roots of the crop to increase the transplantation rate of crop seedlings In addition, since it does not cause pests such as flour bottles and aphids, it can greatly reduce the amount of spraying and fertilizing of pesticides and fungicides, and it is excellent in sugar when sprayed on fruits, and it is possible to harvest fruits containing organic selenium. It is an object to provide a fertilizer and a method for producing the same.

The present invention devised to achieve the above object is a horticultural fertilizer characterized in that it comprises the step of concentrating the extract extracted from stevia plant tissue, fermentation and aging, and then adding selenium to the mature concentrate. It provides a manufacturing method.

And it provides a horticultural fertilizer, characterized in that it is manufactured by the method for producing a horticultural fertilizer.

Hereinafter, the horticultural fertilizer of the present invention will be described in detail.

The horticultural fertilizer of the present invention comprises stevia extract and selenium.

The stevia extract is dried and pulverized stevia leaves and stems, soaked in the water and then heated to extract the active ingredient, the concentrated stevia concentrate, and the stevia concentrate is fermented and aged under a suitable environment from bacteria Beneficial ingredients include the resulting mature solution. Such stevia extract has a sugar content of 200 to 300 times that of sugar but 1/90 of the calories compared to sugar, and antioxidant activity is about 5 to 7 times that of green tea.

In more detail, the stevia concentrate comprises a drying step, such as a stevia leaf, a grinding step, an extraction step and a concentration step.

The drying process is a step of sufficiently growing the stevia plant, selecting and harvesting the leaves and stem portions of the stevia plant, and the natural leaves or forced drying of the collected leaves and stem portions. Although the leaves and stems may be naturally dried, forced drying using a dryer is recommended to quickly and uniformly dry the leaves and stems. It is usually dried at 75 ± 15 ° C for about 1 day.

Then, the stevia leaves and stems dried by the drying process are subjected to a pulverization process to grind to a predetermined size so that the effective ingredients contained in the stevia leaves and stems more effectively during the subsequent extraction process.

Next, the extraction process is a step of extracting the active ingredient from the stevia leaves and stems by heating the pulverized product pulverized in the crushing step into an extraction container containing water.

Stevia leaves and stems to be put into the extraction container may be extracted only the leaves or the active ingredient using only stevia stem, depending on the intended use, may also be extracted by mixing the appropriate amount of stevia leaves and stem.

In order to more effectively extract the active ingredient from the pulverized product, other solvents may be mixed with water, and the active ingredient may be extracted from the pulverized product at a pressure higher than atmospheric pressure.

When the active ingredient is extracted from the milled product under pressure above atmospheric pressure, the boiling point of the milled water and the like is increased, thereby effectively extracting the active ingredient contained in the milled product.

In addition, the concentration step is a step of concentrating the extract extracted from the stevia plant tissue, transfer the extract extracted in the extraction step to a concentration tank, and then heat the concentration tank to obtain a concentrate from the extract.

At this time, it is preferable to concentrate by adding heat to the concentration tank while stirring the extract of the concentration tank, which is to prevent the active ingredient of stevia to stick to the inner peripheral surface of the concentration tank.

And it is preferable to concentrate an extract liquid by applying heat to a concentration tank in the state which made the atmosphere in a concentration tank into the pressure below atmospheric pressure. When the pressure in the concentration tank is below atmospheric pressure, the boiling point of the extract is relatively low compared to the boiling point at atmospheric pressure, so that less energy is consumed and the energy required for concentration is greatly increased. There is an advantage that can be shortened.

In this way, a stevia concentrate is obtained.

And the stevia aging liquid refers to a solution obtained by fermenting the stevia concentrated solution after aging for a certain time.

In the method of obtaining the aging solution from the stevia concentrate, the concentrate is fermented at a temperature of 20 to 30 ° C., and then aged for a certain period of time. And the fermentation process can be carried out by the method of fermenting the concentrate by the yeasts present in the natural state, it is preferable to shorten the fermentation period by promoting the fermentation by treating the previously cultured yeasts in the concentrate.

In the fermentation process, it is preferable to inject oxygen into the concentrate at regular intervals. Periodically injecting oxygen into the concentrate as yeast bacteria involved in fermentation are mainly aerobic microorganisms, which promotes fermentation and proliferation of yeast bacteria involved in fermentation. Providing there is an advantage that can prevent the fermentation caused by the decay bacteria during fermentation.

At this time, it is preferable to inject oxygen into the low water level of the concentrate, and more preferably, to the bottom of the concentrate. This is because oxygen supplied to the bottom of the concentrate is increased by buoyancy so that not only the yeasts present on the surface but also the yeasts growing on the bottom are vigorous to grow, and the decayed bacteria can grow relatively. This is to prevent corruption by providing a clean environment.

In addition, selenium is a major component of the horticultural fertilizer of the present invention, a trace element distributed mainly in the liver, kidney, heart, and spleen, and is a powerful component of an enzyme that decomposes hydrogen peroxide generated in the body to prevent cell damage. Known as an antioxidant. Ingesting an appropriate amount of selenium reduces the body's demand for vitamin E, prevents red blood cells from oxidizing and destroying it, and also helps regenerate the liver in cirrhosis and delay aging. In addition, selenium binds to heavy metals such as mercury, cadmium, and lead to inactivate them, thereby preventing heavy metal poisoning.

Therefore, when ingesting selenium-containing fruits and vegetables, it can suppress the aging of the cells of the body and prevent cancers such as lung cancer and prostate cancer, and it is a poisonous form of heavy metals such as lead, mercury and cadmium in the body. It is transformed into the body to be discharged to the outside has the advantage of preventing heavy metal poisoning.

In addition, it is preferable to use organic selenium, which has better absorption in the body than inorganic selenium and is more effective in physiology and metabolism.

The content of the selenium can be appropriately adjusted depending on the concentration of stevia extract and the type of crop to be fertilized.

In addition, the method of containing the selenium in the stevia extract may be added by adding an appropriate amount of selenium to the stevia concentrate, may also be added after fermentation or after aging.

Hereinafter, the horticultural fertilizer of the present invention will be described in more detail with reference to Examples, but the present invention is not limited to the following Examples.

Example 1

Stevia leaves and stems were dried, pulverized and mixed, and then placed in permeable heat-resistant sacks 3kg each. Into the extraction vessel containing water, two heat-resistant sacks containing crushed powder were added, and heated to a temperature of 110 ± 10 ℃ for 2.5 hours to extract the active ingredient contained in stevia. The extracted extract was placed in a concentration bath and heated to a temperature of 110 ± 10 ° C. under negative pressure for 13 to 15 hours while stirring to obtain a concentrate. The fermentation vessel was then placed in a fermentation vessel, followed by a fermentation process at 20 to 30 ° C. for 5 days, and 2% of selenium was added to the fermentation solution thus fermented. Completed.

Tomato seedlings grown in seedlings were planted in the soil (Gochang-gun, Jeonbuk). And tomato seedlings were sprayed with a diluted horticultural fertilizer, which was diluted 1000 times with the horticultural fertilizer of Example 1 using water. After that, the tomato seedlings were sprayed seven times every 10 days, and then tomatoes were harvested.

[Control]

Tomato seedlings grown in seedlings were planted in the soil (Gochang-gun, Jeollabuk-do), and fertilizers were commonly used at each fertilization period to harvest tomatoes.

The tomato roots sprayed with the horticultural fertilizer of Example 1 had better vigor compared to the tomato roots of the control group, so that the transplantation rate into the soil was excellent, and the tomatoes of Example 1 did not cause pests such as flour bottles and aphids. Therefore, only half of the pesticides and fungicides were used compared to the control.

And the tomatoes in the control were opened up to 7 stages on average, but the tomatoes grown by spraying the horticultural fertilizer of Example 1 were opened up to 9 stages. It was. This is considered to be because carbohydrates, amino acids, organic acids, enzymes, etc. among the components contained in the horticultural fertilizer of Example 1 grew useful microorganisms to improve the growth environment of tomatoes.

In addition, the average sugar content of the tomatoes grown and harvested by spraying the horticultural fertilizer of Example 1 was 9.5 degrees, and the average sugar content of the tomatoes in the control was 6.8 degrees. In the control tomato, organic selenium was not detected or was detected inadequately, but in the case of tomatoes harvested using the horticultural fertilizer of Example 1, 12 to 34 µg was detected per 100 g.

As described above, the horticultural fertilizer of the present invention does not contain any synthetic material and thus does not deplete the soil and improve the growth of useful microorganisms in the soil, thereby improving the adhesion of the roots of crops to increase the transplantation rate of crop seedlings. In addition, since the pests such as flour bottles and aphids do not occur, there is an effect that can greatly reduce the amount of spraying and fertilizing of pesticides and fungicides.

In particular, when the horticultural fertilizer of the present invention is sprayed on fruit crops, the yield is increased, and the sugar content is excellent, and organic selenium-containing fruits can be harvested.

On the other hand, by adding selenium to the fermentation and ripening fermentation of stevia concentrate to produce horticultural fertilizers, it is effective to mass-produce horticulture fertilizers by a simple method, and also periodically air during fermentation and ripening of stevia concentrate By injecting, not only can greatly shorten the manufacturing time of the horticultural fertilizer, there is an effect that can prevent corruption.
