Description

Ginseng cultivation method{Method for ginseng cultivation}

The present invention relates to a ginseng cultivation method, and more particularly, to a ginseng cultivation method capable of increasing the growth of ginseng through light irradiation.

Ginseng is a perennial, shaded herbaceous plant belonging to the genus Panax of the Araliaceae family in terms of plant taxonomy, and has been used as an important medicinal material in oriental medicine for a long time.

Since ancient times, ginseng has been shown to have a surprising effect in treating various diseases and promoting recovery of diseases. Extensive research is being conducted on the efficacy of ginseng to explore its medicinal properties and pharmacological efficacy. The representative efficacy scientifically identified so far is the maintenance of homeostasis of the body control function, and based on this action, anti-fatigue and anti-stress action, anti-diabetic action, blood pressure control action, anti-cancer action, prevention of arteriosclerosis and hypertension, brain Function enhancement, gastrointestinal function enhancement, immune function enhancement, and antiviral activity have been reported.

The first scientific research on the composition of ginseng began in the United States when a mixture of amorphous glycosides was isolated and named Panaquilon.

It has been scientifically proven that there are ingredients with various pharmacological effects in ginseng. Such an action is known to be mainly due to ginseng glycosides, that is, saponin, and other active ingredients include sapogenin, polyacetylene, pyrazine derivatives, and Maltol and the like are known.

However, natural medicinal ginseng is cultivated for 4-6 years in a cool highland with good drainage, and is not only affected by the natural climate, but is an uneconomic product that cannot be serialized in the same place. Therefore, various studies have been conducted to more easily cultivate expensive medicinal ginseng, but the situation is insufficient.

An object of the present invention is to provide a ginseng cultivation method capable of increasing the growth of ginseng through light irradiation in order to solve the problems of the prior art as described above.

The technical problems to be solved by the invention are not limited to the technical problems mentioned above, and other technical problems that are not mentioned will be clearly understood by those of ordinary skill in the technical field to which the present invention belongs from the following description. I will be able to.

Ginseng cultivation method of the present invention, the first step of preparing the seedlings sprouted; A second step of formalizing the sprouted seedlings into a hydroponic cultivation facility; And a third step of growing the cultivated ginseng, and in the step of growing the ginseng of the third step, irradiating the ginseng with light.

In addition, the ginseng cultivation method of the present invention is characterized in that the irradiation of the light is performed in stages, and is irradiated in the order of far-infrared light, mixed light of red light and blue light, and blue light.

In addition, the ginseng cultivation method of the present invention is characterized in that the methyl jasmonate is supplied during the growth of the ginseng.

In addition, the ginseng cultivation method of the present invention is characterized in that the culture medium used in the hydroponic cultivation facility has a temperature of 16 to 20°C and a pH of 5.5 to 6.5.

By means of solving the above problems, the ginseng cultivation method of the present invention has the effect of increasing the growth and increasing the yield by cultivating ginseng through light irradiation that increases the efficacy of photosynthesis.

In addition, there is an effect of increasing the growth of ginseng by optimizing the temperature, pH and culture medium for cultivation of ginseng.

Specific matters, including the problems to be solved, means for solving the problems, and effects of the invention as described above, are included in the following examples and drawings. Advantages and features of the present invention, and a method of achieving them will become apparent with reference to the embodiments described below in detail together with the accompanying drawings.

Hereinafter, the ginseng cultivation method of the present invention will be described using the drawings and examples.

The ginseng cultivation method of the present invention includes a first step of preparing sprouted seedlings, a second step of planting the sprouted seedlings into a hydroponic cultivation facility, and a third step of growing the planted ginseng.

First, in the first step, a sprouted seedling is prepared.

Specifically, the seedlings are moisturized by covering with plastic in a box at a temperature of 15 to 20°C, and for 3 to 5 days, 1 to 3 cm of sprouts are prepared, and strong seedlings are prepared.

In the box, the seedlings are placed so that the head of the brain is 10 to 80 degrees above the slope. When the brain head is immersed in water, it is easily decayed or bitten, so that germination does not occur smoothly, and when it is placed upright at 80 degrees or more, it is inconvenient to work.

The seedlings laid on the floor with paper or cloth to moisturize and arranged at an angle are covered with paper or cloth to moisturize. Then, water is poured into the box so that the root portion is immersed.

In addition, 20 to 80umol of light is supplied when the shoots are sprouted.

The type of light can be variously selected by the operator, such as a fluorescent lamp, sodium lamp, incandescent lamp, and LED lamp.

Next, in the second step, the sprouted seedlings are formalized as a hydroponic cultivation facility.

The hydroponic cultivation refers to a method of growing plants in a culture medium made of water and water-soluble nutrients without using soil. According to an embodiment of the present invention, ginseng may be cultivated in a facility equipped with an irrigation facility, and related facilities may be installed in the facility for temperature and humidity management.

According to an embodiment of the present invention, the seedlings sprouted above can be formally cultivated in a hydroponic cultivation facility equipped with an irrigation facility.

The interior of the hydroponic cultivation facility may include fine beads.

The fine beads may be made of glass (eg, glass beads), plastics, or the like.

By arranging the fine beads in the hydroponic cultivation facility, diffuse reflection and retroreflection by the fine beads are generated during light irradiation, so that the light source can be irradiated three-dimensionally and efficiently (effectively in dispersing the LED light).

The bead may be implemented in various colors by using a pigment, and is basically provided in a white color suitable for reflection, and various designs are changed according to the type of light to be irradiated or the purpose of the user.

In addition, it is preferable to use the bead having a size of 100 to 400 μm and a refractive index of 1.9 to 2.0 in order to increase the reflection effect.

Next, in the third step, the formal ginseng is grown.

The front leaf period in which the main leaf of ginseng is unfolded is a period including a seedling period, and the temperature is maintained at 16 to 20°C during the seedling period, and may be maintained at a temperature of 16 to 20°C during the growing period.

If the temperature is out of the range of 16 ~ 20 ℃ in the seedling stage, there is a risk of causing cold damage or disease. In addition, when the temperature is out of the range of 16 to 20°C during the growing season, there is a concern that growth may be suppressed or high temperature damage may occur.

A fan device may be used to control the temperature.

In addition, it is possible to keep the humidity somewhat high at 80-90% during the seedling period. For example, the anterior leaf period of ginseng may be 30 days after planting, and the seedling period included in the anterior leaf stage may be 14 days after planting. In addition, the humidity can be maintained at 60 to 80% during the growing season of ginseng. The growing period of the ginseng may be from the seedling period to the harvest.

In the seedling period, when the humidity is out of the range of 80 to 90%, there is a concern that the growth of the seedlings may be suppressed. In addition, when the growth period is out of the range of 60 to 80%, there is a concern that growth may be inhibited or disease may occur.

A fan device may be used to control the humidity.

When growing the ginseng, it is possible to increase the growth of ginseng by irradiating light.

By cultivating ginseng in the hydroponic cultivation facility, environmental control is easy, and ginseng can be cultivated in a short period of time (3 to 4 months) by promoting growth by irradiation with far-infrared light.

According to an embodiment of the present invention, light irradiation may be performed in stages.

Specifically, the far-infrared light was irradiated for one month (30 days), then the mixed light of red and blue light was irradiated for one month (30 days) to one and a half (45 days), and then blue light was irradiated for two weeks (14 days). By irradiation, light irradiation can be carried out in stages.

First, the far-infrared light is irradiated for 30 days to increase growth.

The far-infrared light is perceived by phytochrome, which is a photoreceptor of plants, to form a shape of the above-ground part such as stem, height, and leaf area increase, and it is possible to increase the efficiency of photosynthesis by activating electron transfer in the first photosystem of photosynthesis. Accordingly, it is possible to increase the growth of ginseng by having high photosynthetic efficiency in the form of the increased above-ground part.

Therefore, by irradiating far-infrared light, it is possible to increase the growth of plant height, leaf length, and leaf width during the initial growth period of ginseng. In this way, the above-ground portion of ginseng can be increased in shape, and the increased amount of light received by the above-ground portion is increased to increase the amount of photosynthesis, so that the growth of ginseng can be effectively increased during the cultivation period.

The irradiation of the far-infrared light may be performed by an LED.

Next, red light and blue light may be irradiated together for 30 to 45 days. That is, red light having a wavelength of 650 to 680 nm and blue light having a wavelength of 435 to 450 nm may be mixed and irradiated.

In addition, red light and blue light may be irradiated in a ratio of 7:3. When irradiated at the above ratio, it is possible to increase the growth promoting effect.

When the ratio of the red light and the blue light is out of the above range, the growth promoting effect may be insufficient.

Next, it is possible to increase the content of saponin by irradiating blue light for 14 days.

According to an embodiment of the present invention, a culture solution may be provided to supply nutrients during cultivation of ginseng. The type of the culture medium is not particularly limited, and a culture medium commonly used in hydroponic cultivation of ginseng may be used.

The culture solution may be supplied at a temperature of 16 ~ 20 ℃, it is preferable that the pH of the culture solution is 5.5 ~ 6.5.

In addition, the electrical conductivity (EC, Electrical Conductivity) of the culture medium is preferably 0.2 to 1.0 mS / cmm. More specifically, it may be 0.2 to 0.5 mS/cmm in the anterior leaf period in the budding period, and 0.7 to 1.0 mS/cmm in the flowering period after the flowering period. If the electrical conductivity is out of its range, there is a concern that growth may be deteriorated.

In addition, according to an embodiment of the present invention, the supply of the culture medium may be stopped and only water may be supplied one week before harvesting.

According to an embodiment of the present invention, methyl jasmonate may be supplied to ginseng. Methyl jasmonate may be represented by the following formula (1).

Methyl jasmonate can increase the content of saponin by promoting the expression of a gene that produces saponin in a concentration-dependent manner.

The methyl jasmonate may be supplied at a concentration of 50 to 500uM.

The methyl jasmonate may be supplied from 1 week before harvesting, and may be supplied 1 to 3 times a day.

According to an embodiment of the present invention, the method of supplying the methyl jasmonate is not particularly limited, and may be supplied by, for example, irrigation treatment or side surface treatment. The side treatment can be carried out by spraying a methyl jasmonate solution with a sprayer.

In addition, when the methyl jasmonate is supplied, jasmonic acid, cytokinin, and chitosan may be mixed and supplied to control the growth of ginseng and increase the active ingredient. When the mixture is supplied, 0.5 parts by weight of jasmonic acid, 0.5 parts by weight of cytokinin, and 1 part by weight of chitosan are mixed and supplied with respect to 8 parts by weight of methyl jasmonate.

Ginseng grown according to an embodiment of the present invention may have an increased content of ginsenosides and saponins such as Rg1, Re, Rg2, F2, and K. Accordingly, pharmacological effects such as cancer prevention, inhibition of cancer cell growth, lowering of blood pressure, protection of cranial nerve cells and improvement of learning ability can be expected.

In the following, an experiment on ginseng prepared through the ginseng cultivation method of the present invention is performed, and the experimental results thereof will be described in detail using examples.

[Experimental conditions]

1) Temperature management

Ginseng was cultivated by hydroponic cultivation in a facility equipped with a fan device. It was maintained at a temperature of 16~20℃ during the seedling period when germinating and developing the main leaves after planting, and maintained at a temperature of 16~20℃ during the growing season.

2) humidity management

During the seedling period (about 14 days after planting), when the leaves germinate after planting, the humidity was kept slightly high in the range of 80 to 90%, and the brain head of ginseng germinated and maintained the humidity at around 60 to 80% after the leaf development. .

3) light management

(1) Treatment: Far-infrared light, red light of 660 nm, and blue light of 450 nm were irradiated step by step using an LED. (Far-infrared light, red light and blue light mixed light (7:3), blue light)

* Treatment Unit 1: Without microbeads in the hydroponic cultivation facility

Treatment zone 2: Including fine beads in hydroponic cultivation facilities

(2) Control: It was irradiated using an LED emitting red light of 660 nm and blue light of 450 nm with a wavelength of 660 nm.

4) Culture medium management

The temperature of the supplied culture medium is 16~20℃, the pH is 5.5~6.5, the EC is 0.2 for 2 weeks after planting, 0.4mS/cmm for 3-4 weeks, 0.7mS/cmm for 5-6 weeks, From 7 weeks to 1 week before harvest, it was set to 1.0 mS/cmm. One week before harvesting, the supply of the culture medium was stopped and only water was supplied.

[evaluation]

For each ginseng cultivated in the treatment and control, the plant height, leaf length, leaf width and total weight of 30 days, 60 days, and 90 days after planting were measured, and the results are shown in Tables 2 to 4 below.

30 days after planting Super length (mm) Leaf length (mm) Leaf width (mm) Weight(g) Control 50 39 24 1.2 Treatment 1 75 56 28 2.4 Treatment 2 80 62 30 2.7

60 days after planting Super length (mm) Leaf length (mm) Leaf width (mm) Weight(g) Control 55 39 24 2 Treatment 1 78 58 30 4.2 Treatment 2 81 60 31 4.8

90 days after planting Super length (mm) Leaf length (mm) Leaf width (mm) Weight(g) Control 50 40 24 2.8 Treatment 1 79 58 30 6.3 Treatment 2 80 60 31 7

Referring to Tables 2 to 4, the growth of ginseng in the treatment group grown under the light source irradiated with light in stages was significantly increased compared to the ginseng grown in the control group irradiated with red and blue light. The weight of ginseng at 90 days after planting, the final harvest time, was increased by 2.6 times in the treated group (based on treatment group 2) compared to the control group.

More specifically, the plant length, leaf length, and leaf width of both control and treatment groups increased until 30 days after planting, when the morphological formation of the above-ground portion of ginseng was completed, and the plant length, leaf length, and leaf width of the ginseng were kept constant. However, in the treated group, the increase in plant height, leaf length and leaf width was much greater until 30 days after planting compared to the control group. In addition, it was confirmed that the total weight of ginseng in both the control and treatment groups continued to increase over time, but the increase rate of the ginseng weight was higher in the treatment group compared to the control group.

In addition, among the treatment groups, it was found that in the case of treatment group 2, the increase in plant height, leaf length, leaf width, and ginseng weight increase were higher.

Therefore, it is judged that the stepwise light irradiation increases the above-ground part of ginseng morphologically, and the increased amount of light during the cultivation period increases the amount of photosynthesis, thereby effectively increasing the growth of ginseng.

As described above, it will be understood that the technical configuration of the present invention described above can be implemented in other specific forms without changing the technical spirit or essential features of the present invention by those skilled in the art.

Therefore, the above-described embodiments are to be understood as illustrative and non-limiting in all respects, and the scope of the present invention is indicated by the claims to be described later rather than the detailed description, and the meaning and scope of the claims and the All changes or modifications derived from the equivalent concept should be construed as being included in the scope of the present invention.
