Description

Tea cultivation method using an eco-friendly cultivation composition {Cultivation Method of Eco-Friendly Tea tree and the tea cultivated by the same}

The present invention relates to a tea tree cultivation method using eco-friendly herbal extracts without using harmful chemicals and chemical fertilizers.

The tea tree is an evergreen tree belonging to the Camellia family (Theaceae) and Genus: Camellia, and its scientific name is Camellia sinensis. Cultivated tea tree can be divided into Assamica (var.assamica) and Chinese (var.sinesis), and the Assam species has the characteristics of large leaves, is distributed in tropical and subtropical regions such as India and Sri Lanka, and has weak cold resistance, but black tea It is widely used as a dragon, and if the Chinese species has leaflet characteristics, it is distributed in temperate regions such as Korea, China, and Japan and has strong cold resistance.

The Korean native tea tree is mainly classified as a Chinese species. The tea tree is a subtropical crop, and the optimum temperature for growth is 14~16℃ in average annual temperature. Low temperature is a limiting factor for tea tree growth, and even in varieties with strong cold resistance, leaves die when 1 hour passes at -15℃, and high temperature failure occurs when it exceeds 40℃. The minimum amount of precipitation required for the growth of tea trees is 1,300 mm, but for optimal tea cultivation, more than 1,500 mm of precipitation is required per year.

In the case of Korea, it is reported that Daeryeom imported tea seeds from China in 828 at the end of the Silla Dynasty and planted it around Mt. Its native habitat is mainly in the southern region south of the cultivation limit line with an average temperature of 13℃, and is cultivated in Jeonbuk, Jeonnam, Gyeongnam, and Jeju.

Tea is characterized by containing a lot of nitrogen compounds, polyphenols, sugars, organic acids, vitamins and minerals compared to other favorite beverages. It is also known that the components of these amino acids are correlated with the price of the product. The total nitrogen content of tea leaves has traditionally been an important factor in determining tea quality along with amino acids.

About 20% by weight of the total nitrogen content of tea leaves is caffeine, and other nitrogen compounds include amino acids, amides, proteins, and nucleic acids. Tea protein is hardly eluted because it binds to tannins during the manufacturing process or is coagulated by heating.

In addition, tea has been widely used since ancient times because it has various pharmacological actions as well as a favorite beverage. In recent years, research has been actively conducted on the functionality of tea. Tea contains a lot of polyphenols in particular, and most of the polyphenols in tea are flavonoids known as catechin compounds.

Theanine is a component with a high specific gravity accounting for about 40 to 60% by weight of the total free amino acids in green tea. Theanine component has a great influence on the umami taste of tea, and is correlated with tea quality along with total free amino acids and total nitrogen, and is used as an important index in quality evaluation along with sensory evaluation, which is an important selection for the development of new tea tree varieties. is evaluated as a factor.

On the other hand, the tea tree is an omnivorous crop in which cross-pollination occurs between individuals with different genotypes, and there is severe inter-individual variation. Therefore, conventional tea trees that are generally cultivated are not single varieties, but hybrids that have been passed down through sexual reproduction for a long time. Each tea tree has different genetic traits, so harvest time, growth rate, leaf shape and color, composition, disease resistance, cold resistance There are several different characteristics such as Although these native species have high genetic value for breeding, it is necessary to develop tea tree varieties that can maintain uniform quality while exhibiting excellent functionality even after multiple breeding. However, improving tea tree varieties according to the breeding method requires a long time and expensive research process. The need is urgent in reality.

In addition, galgeun produces sweat, lowers fever, treats high fever and headache, quenches thirst, is used for indigestion, headache, anemia, dysentery, abdominal pain, alcohol poisoning, cold, vomiting and women's bleeding and helps digestion.

Hyangbuja (Cyperus rotundus) has been reported as an analgesic or antispasmodic in oriental medicine. In addition, it has been recently reported that the extract of Hyangbuja exhibits anti-inflammatory effects. In the present invention, the rhizome of Hyangbuja having various analgesic, antispasmodic, antioxidant, and anti-inflammatory effects is used as a natural product raw material, and functional extracts of Hyangbuja anti-aging effect are used through the components in the natural product.

Excess fruit is the dried fruit of chodugu, a tropical plant belonging to the ginger family. It is similar in appearance to ginger, but has a purple color and a spherical shape, and is widely used as a herbal medicine. It is known that excess is low in calories, which is beneficial for diet, relieves all colds, warms the stomach, stops vomiting, and only relieves abdominal pain.

Sukjihwang is a dried ginseng root that is steamed and dried, and the process of steaming and drying the dried ginseng is repeated 3 to 4 times. The taste is sweet and slightly bitter, and the nature is warm. It works on the nerves, liver, heart, and heart. It mainly nourishes blood and groan, replenishes water and darkens hair. In pharmacological experiments, anti-atherosclerotic activity was found. And Sukjihwang is the main medicine for samultang, and it is used for symptoms such as heat resistance, dry throat, and thirst, which are caused by weakness of the body among various chronic diseases.

Malvaverticillata Linn is a mature seed of mallow, an annual herb belonging to the mallow family. It is rich in protein and 15-30% fatty oil, so it increases diuresis and blood flow. It has been reported to be effective for the lack of milk in pregnant women and inflammation of the breast. In the present invention, it is preferable to use the copper guise after drying.

Cammpsis grandiflora is a tendril plant belonging to the family Bignoniaceae and is used to treat diseases caused by blood clots or blood fever. The color of the corolla is orange, but the outside is reddish-yellow. In oriental medicine, the flowers that just started blooming in July-September are dried in the sun and used as a live blood medicine and as an analgesic for postpartum diseases, menstrual irregularities, diuretics, and antipyretics. . It is also used for postpartum mastitis, and when the skin is itchy due to blood fever, add water and take it as a decoction.

"Hyunsam" is a perennial herb with ginseng. The stem is hairy and the leaves are narrow and long. The flowers are pale yellow-green, bloom in August-September, and the roots are white in lumps, but turn black immediately when cut. Hyeonsam is a succulent herb that dries up the stems on the ground during the winter and only the roots live, then sprout again in the spring of the following year. In oriental medicine, the root is used as medicine. Hyeonsam likes a place with a mild climate and a lot of moisture, and is resistant to cold. It is distributed in Korea, China, and Japan, and in Korea, it is produced a lot in Gyeongbuk. It is also called Jungtae, Jeongma, Hyeontae, Gwijang, Chukhor, Wonsam, Jeongma, or Black ginseng. Its main ingredients include scropoladin, phytosterol, and phytosterin, and other sugars, essential oils, and fatty acids. Ginseng lowers heat, strengthens heart function, and prevents inflammation, so it is used for sore throat, tonsillitis, conjunctivitis, and lymphadenitis, and is effective in various high fever diseases. The main effects in oriental medicine are consonant (滋陰), fortification (降火), detoxification (除煩), detoxification (解毒), yang blood (凉血), saengjin (生津), sewage (下水), myongmok (明目). ), noon bowel, vomit blood, ear infu (利咽喉), general urine (通小便), small bell poison (消腫毒), longevity detoxification服), Boheo (補虛), etc.

The cephalothorax is the stem bark of Eucommia ulmoides Oliver (Eucomiaceae), and is not particularly limited as long as the epidermis is removed. These headworms are excellent in relieving hangovers by increasing the diuretic and nerve sedative effects in the body after drinking. In addition, the cephalothorax contains components such as pinoresinol diglucoside, which further improves the decomposition of alcohol in the body, increases the rate of excretion of hangover-causing substances, and improves hangover symptoms such as vomiting, nausea, and indigestion. is excellent Duchung in the main material mixture may be included in an amount of 1 to 10% by weight, specifically 2 to 7% by weight. Within the above range, the liquid tea composition for relieving a hangover further activates the decomposition of alcohol in the body, and the effect of reducing blood alcohol concentration and exhaled alcohol concentration at a faster rate may be further improved.

The liquid preparation according to the present invention, 60 to 90 parts by weight of herbal medicines selected from the group consisting of hyangbuja, supernatant, sukjihwang, donggyuja, rhododendron, ginseng, and duchung are mixed with respect to 100 parts by weight of garlic root. In a preferred embodiment, based on 100 parts by weight of garlic ginseng, 75 parts by weight of hyangbuja, 75 parts by weight of excess, 90 parts by weight of Sukjihwang, 60 parts by weight of donggyuja, 60 parts by weight of ginseng, 90 parts by weight of ginseng, and 75 parts by weight of duchung are mixed.

For the mixture of each of the mixed herbal medicines, the hot water extraction temperature is carried out for 90 minutes to 120 minutes at 100 ~ 120 ℃. In this case, the mixture is mixed with water 5 to 8 times the total weight of the herbal medicine mixture so that the hot water extraction process can be performed. For example, when the mixture of herbal medicines is 1250 g, 10 L of water can be mixed to extract. (The mixing ratio of herbal medicines and water for hot water extraction is preferably 1: (5-8) by weight.)

The extract of the herbal medicine mixture to be extracted is filtered, and pouch packaging of 120 ml unit (1 tablet) is performed to complete the liquid formulation of the present invention. When supplying tea trees in the future, dilute it with 60L of water per 1 tablet (120ml) so that it can be supplied. (Extract:water=1:500 volume ratio) Usually, 1 liter (L) of water is hops to 125g of herbal medicine, and 120 at 100℃ In the case of decoction in a decoction device, 5 cheops (600 ml) of the extract can be obtained.

2. Method of supplying liquid to tea tree

In the method of supplying liquid fertilizers or drugs to tea trees, the main method is spraying on the leaf surface in order to exert intuitive effects (insect repellent, control, etc.) on tea leaves. In the case of spraying with this method, it may affect the taste and aroma of tea grown later. Accordingly, the foliar spraying method is avoided, and the underground supply method of supplying liquid to the roots of tea trees can be applied. In addition, in addition to the underground supply method of the liquid agent, a liquid agent supply method in which the tea leaves are not directly supplied by ring irrigation or the like can be applied.

This underground supply method is implemented by applying the liquid agent of the present invention to the root system of the tea tree. In the range of m, underground irrigation can be carried out at a depth of 10-30 cm from the surface.

In the case of this underground irrigation method, the liquid agent of the present invention is not randomly sprayed on the surface of the child, but the concentrated liquid agent of the present invention is mixed with water and diluted and supplied, and the ratio of water: liquid agent is 60L: 120ml (500 : 1 volume ratio) so that the diluted solution can be supplied.

In particular, a plurality of trenches at a depth of 10 to 30 cm from the ground surface are formed in the radius of the center of the tea tree, and the diluent is supplied to the trench, or an injection-type injector is inserted into the soil at a depth of 10 to 30 cm. The spraying method can be applied to 3-5 places. This is because, when the diluent is supplied directly to the ground surface, there is a high possibility that the liquid agent will be dispersed or lost due to exposure to moisture or the environment supplied from the outside, so that the ratio of the liquid agent supplied to the tea tree roots is significantly reduced. Through the supply method, it is possible to increase the efficiency of contact between the root of the tea tree and the liquid agent.

The application time of the liquid agent is preferably so that the application of the liquid agent can be made 1 to 2 months before the time of picking tea leaves. In a preferred embodiment, irrigation may be performed once before winter, and irrigation may be performed 2-3 times in March or April, which is spring.

As another example, the first liquid application may be performed in March to April, the second liquid application may be performed from late July to late August, and the third liquid application may be performed in the period from September to November.

In the case of spraying before dormancy, the spraying time is preferably from October to early December, particularly just before entering the dormancy period. In the case of spraying after sprouting, it is the period from sprouting to red cutting.

In the case of spraying after sprouting, spraying should be carried out at least once, and as the number of spraying increases, the amount of active ingredient accumulated in the tea leaves also increases, and as shown in the experimental example to be described later, the content of the active compound also increases, but the number of spraying The change in the increase effect by A certain amount of time is required for the change in the metabolic mechanism according to the active ingredient of the liquid agent absorbed by the root of the tea tree to become significant, and it is preferable to apply the spray 5 to 25 days before the red cabbage.

The tea tree has strong regenerative power, and the buds grow 4 to 5 times a year, so that it can be harvested 3 to 4 times, and the harvest of tea leaves is repeated several times. In general, the content of amino acid-based compounds contained in tea leaves is highest in single leaf tea, and in the case of late-harvesting tea leaves, the content usually decreases. It is expected that the quality of tea leaves after the second leaf tea will be improved by applying the cultivation method of

In addition, the content of amino acid-based compounds varies depending on the part of the tea leaf, and in order to produce high-quality tea, it is limited to younger leaves (for example, the upper leaves from the planting plant to the second tube), or the red harvesting day is expedited. However, by increasing the content of amino acid-based compounds in tea leaves according to the cultivation method of the present invention, tea leaves with a high amino acid content can be obtained even if the area to be harvested or harvested is delayed. It is expected that most of the yields of high-quality tea leaves will be possible.

{Experimental Example 1}

The tea tree to be the experimental sample was selected from 500 tea trees (15 years old) grown on 1 ha in the tea plantation site located in Jeongeup-si, Jeollanam-do of the applicant, and 100 strains of comparison group and 400 strains that do not apply the liquid agent of the present invention by division The experimental group was divided into 4 groups, and the liquid formulation of the present invention was administered to 4 experimental groups from October 2018 to March 2019 for a total of 1 comparative group (100 shares) and 4 experimental groups (400 shares) per tea tree. 120 ml of the liquid formulation (diluent: liquid extract: water = 1:500 ratio) was diluted with 60 L of water, and 1 L of the diluent was added. The time of injection was after irrigation once at the end of November and then 3 times during the period from early March to April.

(In the case of the added liquid, for 100 g of ground root, 75 g of hyangbuja, 75g of excess, 90g of Sukjihwang, 60g of Dongguja, 60g of jacaranda, 90g of ginseng, and 75g of duchung are mixed, and 625g of the mixed mixture and 3125g of water are mixed with a decoction at 120°C. A liquid extract was formed by hot water extraction at a temperature of 5. In the case of the extracted liquid extract, it was diluted in a ratio of 120 ml of liquid extract and 60 L of water, and the diluted diluent was used in the underground irrigation method and injected into the adjacent part of the tea tree. )

{Example 1}

For 100 tea trees belonging to Group 1 belonging to Example 1, a 1 m round height was formed at the center of the tea tree by 30 cm, and the liquid agent was added.

{Example 2}

For 100 tea trees corresponding to group 2 belonging to Example 2, the liquid agent was injected at a point 30 cm away from the center of the tea tree at a point 30 cm underground using an injector.

{Example 3}

The liquid agent was added in the manner performed in Example 1, but the diluted solution having a concentration twice that of Example 1 was added in the same amount.

{Example 4}

The liquid agent was introduced in the manner performed in Example 2, but the concentration to be added was diluted to twice the concentration of Example 2 and the same amount was added.

{Comparative Example}

As a comparison group, the same cultivation method (fertilization, irrigation, etc.) was applied to 100 tea trees grown in the same cultivation area, but without liquid material input.

For each group of tea trees grown in the same manner as described above, sample tea leaves were collected by randomly harvesting 3-5 tea leaves per week, and the tea leaves collected in each Example group were stirred and dried at a drying temperature of 50° C. for 90 minutes. and pulverized to an average particle size of 100 μm.

In the case of pulverized tea leaf powder, 600 ml of water was added to 10 g of the sample and boiled at 100° C. for 1 hour before proceeding. The functionalities of green tea leaves were comparatively analyzed by measuring the contents of catechins, total polyphenols, and total flavonoids by ODS-HPLC.

The catechin content was measured in the following way. 60 ml of 100% methanol was added to 0.5 g of powdered tea leaves, extracted for 24 hours at room temperature, and extracted twice, and the extracted sample was filtered through a 0.45 μm membrane filter and used as a sample for HPLC analysis. The gradient method was used so that the injection amount of the sample for HPLC analysis was 20 μl.

The total polyphenol content was measured in the following way. After adding 1 ml of Na2CO3 solution to 1 ml of green tea leaf extract, and leaving it for 3 minutes, 0.2 ml of 50% Folin-ciocalteu reagent was added to react, and left at room temperature for 30 minutes. After centrifuging the mixture at 12,000 rpm for 10 minutes, 1 ml of the supernatant was taken and absorbance was measured at 750 nm. The total phenol content was converted to a standard curve prepared using gallic acid.

Total flavonoids were measured in the following way. After grinding the dried green tea leaves for 1 minute to make a powder sample, 60 ml of 50% methanol solution was added to 1 g of the sample, followed by extraction under reflux at 800° C. for 1 hour. After cooling, 50% methanol was added to the extract to make 100 ml, and it was filtered using filter paper (Whatman No. 1).

{Table 1}

Contrast Results As a result of analysis of the content of tea leaves in the comparative group and in Examples, the catechin content was 1.8 (mg /g) was confirmed to represent 2.3, 2.5, 3.1, 3.0 (mg/g), which increased by about 25-30%.

In addition, the increase rate of polyphenols was also shown to be increased by 50% or more compared to the components of the tea leaves of the cultivation zone that did not use the liquid formulation of the present invention and the components of the tea leaves of the Examples in which the liquid formulation of the present invention was added, and the probonoid content was 30% also appeared to increase.

In the case of the difference in the component concentration of each tea leaf according to the difference in the concentration of the liquid agent of the present invention to be added for each example, when considering the contrast between Example 1 (1 times) and Example 3 (2 times), cultivation under the same conditions, It can be confirmed that the concentration of the active ingredient is high in the 2-fold treatment group at a ratio of about 5 to 15%, which is confirmed to show a similar tendency in the comparison of Examples 2 and 4.

Looking at the above experimental results, in the case of tea leaves harvested by the cultivation method of tea trees to which the liquid preparation of the present invention is applied, the ratio of the active ingredient appearing higher than that of the individual derived by the existing general cultivation method is improved by about 10 to 30% overall. it can be confirmed that

The content of active compounds such as catechins, polyphenols and flavonoids in tea leaves during growth is increased. The content of which compound is increased varies depending on the time of spraying or the growing environment of the tea tree, and is related to the metabolic mechanism of tea leaves, but the sensitization effect on theanine is always seen, so the total amino acid compound is about 20-40% by mass. increase is expected.

{Experimental Example 2}

The results of the sensory test performed on the samples harvested in Experimental Example 1 above are as follows.

In Examples 1 to 4 and Comparative Examples, each sample was subjected to a sensory test for taste, color, preference, etc. on tea water obtained by brewing powdered tea leaf powder in water at 100° C. Table 2 shows.

The results of sensory evaluation performed on each sample by a 5-point scale method targeting a panel of 30 people with excellent taste are shown in Table 2 below.

In all test items, it was evaluated to be excellent in all respects compared to the comparative example (tea leaves grown without the administration of liquid). In particular, in terms of the flavor (taste, texture) of tea, in the case of tea leaves grown according to the present invention, it is judged that the bitterness and astringency of tea are less, and it is judged that it improves the preference by providing the rich flavor of tea.

{Table 2_sensory evaluation result}

(In Table 2, the numerical values for sensory properties such as taste, color, and preference of the experimental groups of Examples 1 to 5 and Comparative Examples are rounded to the second decimal place after dividing the total of the panel scores by the number of panels. The higher the number, the higher the number. It means that the sensibility is excellent.)
