Description

  The present invention relates to a method for cultivating tea, and more particularly, to produce tea with excellent quality by applying a soil conditioner, mineral, and ultra-trace mineral.

  In recent years, due to reflection on the heavy use of chemical fertilizers and chemical pesticides, organic farming and organic cultivation using compost etc. have been carried out, but these are mainly from the aspect of safety such as low pesticide or non-pesticide cultivation. However, it is difficult to obtain sufficient quality improvement of agricultural products by these methods alone, and it is difficult to enhance umami and richness. There is a need to develop an excellent system that can replace this method.

  Therefore, the present inventor has previously developed a new type of soil conditioner that should be called artificial compost, which is a mixture of an inorganic ion exchanger, a hydrophilic organic polymer, an organic material, and a microorganism (Patent Document 1). ).

Certainly, this soil conditioner has excellent aggregate formation ability, and when tea is grown by fertilizing three elements of nitrogen, phosphoric acid, and potash according to conventional methods, the quality improvement of tea to some extent is not possible. Although it could be achieved, it was not possible to reach a satisfactory range, and this soil conditioner took time to apply, and the need for further improvement was recognized.
Japanese Examined Patent Publication No. 4-75952

  The present invention has been made in view of the above-mentioned present situation, and has recently focused on tea, which is particularly highly interested by consumers, and cultivated tea trees without using fertilizers and pesticides as much as possible. It was made for the purpose of manufacturing.

  As a result of examinations from various directions to achieve the above object, the present inventor, first, in the field where plants with high geological power and high harvest are maintained and where the plants are growing healthy, there is little occurrence of pest damage. Focusing on the soil of these areas, conducting extensive Shiyan analysis, and as a result of earnest research, in addition to a large amount of essential elements (nitrogen, phosphoric acid, potash), specific trace elements (inorganic components or minerals) ) And ultra-trace elements (sometimes referred to as ultra-mineral minerals), not only the type but also the required quantity, and even more groundbreaking, We obtained new knowledge that a certain balance (sometimes called mineral balance) is necessary (Fig. 1).

  Moreover, contrary to the above, when the nutrition of a crop is bad and its health is damaged, it became easy to generate pest damage, and in such a case, it was discovered that the mineral balance in the soil is broken. In general, in Japan, there were too many essential elements, but there was an analysis result that the trace elements were too small and the balance was not maintained.

  From these findings, the present inventor obtained a novel idea that the occurrence of pest damage is suppressed and the use of agricultural chemicals is suppressed if the crop is cultivated in a healthy manner, and that mineral balance is necessary for that purpose. Attempts have been made to apply large amounts of trace elements for implementation, but have not been fully successful.

  Therefore, physical, chemical and biological studies were conducted. And in the process of studying the structure of the soil, even if it is cultivated soil, there is a layer of solidified soil underneath, and the applied mineral moves smoothly from that layer down. As a result, it was found that minerals hardly reach the roots of plants.

  Based on these new discoveries regarding the behavior of minerals in the soil, the countermeasures were examined from various directions, but it did not succeed. Therefore, the minerals were mixed with the soil improver previously developed by the inventors. When applied to the soil, the above-mentioned drawbacks were alleviated and unexpectedly promoted plant growth.

  As a result of further research based on this new useful knowledge, the present invention has not only confirmed this useful new knowledge in tea cultivation (that is, tea tree cultivation), but the obtained tea has an amino acid and theanine content. It was confirmed that it was high in flavor, quality and quality, and also had a hair nourishing action (particularly including the action of blackening hair).

  In order to carry out the cultivation method according to the present invention, each material, that is, soil improvement material, mineral, ultra-mineral mineral is applied simultaneously or at different times, but these materials are in liquid form. In addition, liquid forms include suspensions, emulsions, and pastes in addition to solutions.

  The soil improvement material is made of at least one selected from a hydrophilic organic polymer and humic acid. Examples of the hydrophilic organic high molecular polymer include a polymer of maleic acid or a derivative thereof and ethylene-based material, a copolymer of crilium, methyl vinyl ether and maleic anhydride (PVM / MA): melamine resin, polyvinyl alcohol, poly Acrylic acid or its derivatives are used. Among them, the latter is particularly effective, for example, polyacrylic acid soda, polyacrylic acid amide, or a derivative such as a partial hydrolyzate thereof is advantageous, and can form a soil aggregate, Commercial products are fully used.

  As the soil improvement material, in addition to the above-mentioned polymer and humic acid, an inorganic ion exchanger, an organic material, and a microorganism may be blended as desired, but all of them need to constitute the above-described liquid agricultural and horticultural material. is there.

  In addition to zeolite, 1: 1 type clay minerals such as kaolinite and halloysite; 2: 1 type clay minerals such as vermiculite, montmorillonite and illite; clay minerals such as imogolite are used as the inorganic ion exchanger. Among clay minerals, montmorillonite clay minerals such as montmorillonite, beidellite and nontronite are particularly effective. Moreover, the commercial item containing these clay minerals like bentonite can fully be used.

  As the zeolite, any of natural or synthetic zeolite can be used, and for example, clinoptilolite, mordenite and the like are preferably used. These may be mineralogically pure, but these inclusions can also be used satisfactorily, such as green tough. Naturally available zeolites are commercially available and can be used freely such as Nagamanbe, Akita Prefecture Yokote, Shimane Prefecture Iwami Ota, Miyagi Prefecture Kawatomi. Zeolite does not exhibit water swellability, so that effective soil improvement is possible without impairing the water permeability of the soil even when applied to fields with poor drainage. On the other hand, bentonite and the like exhibit swelling properties with respect to water and are suitable for soil improvement in fields with good drainage. As described above, according to the present invention, the most appropriate ion exchanger can be selected according to the soil quality to be applied, and a very excellent soil improvement effect can be obtained.

  Various microorganisms are used as the microorganism, and bacteria, yeasts, actinomycetes and filamentous fungi are useful, and the following are particularly preferable.

(1) Bacteria Bacillus polymixa (Bacillus polymyxa IFO3020)
Bacillus megaterium (Bacillus megaterium IFO3003)
Bacillus brevis IFO3331
Clostridium acetobutylicum (Clostridium acetobutylicum IFO3346)
Pseudomonas fluorescens IFO 3081
Pseudomonas maltophilia IFO12690

(2) Yeast Candida utilis IFO0396
Candida albicans (Candida albicans IFO0197)
Endomycopsis monospora IFO0113
Endomycopsis capsularis IFO0672
Saccharomyces robustus IFO0224

(3) Streptomyces alborongus IFO13465
Streptomyces albus IFO03195

(4) Aspergillus ustus IFO4104
Cladosporium cladosporioides IFO6368

  These microorganisms may be used by isolating cells or spores, or may be used together with a culture medium without isolation. The microorganism may be a single bacterium or a mixed bacterium of several kinds.

  Organic materials include oil lees, rice lees, bran, fish lees, various composts, manure, poultry manure, livestock excrement, rice straw, agricultural production lees, fermented lees, peat, juvenile charcoal, wood, humus, human waste, sludge, lignin Etc. are exemplified.

  In the present invention, the soil conditioner is based on at least one selected from a hydrophilic organic polymer and humic acid, but a preparation of a soil conditioner containing these as active ingredients can also be used, and commercially available products are also used as appropriate. The If further desired, one or two of the above-mentioned components may be blended. However, in that case, it is preferable that the components are completely in solution, but the nozzles and holes of the irrigator and injector If it is in a liquid state that does not cause clogging of parts, pipes, hoses, valves, etc., it is sufficiently durable.

  As a soil improvement agent, when using polyacrylic acid, such as polyacrylic acid amide and polyacrylic acid soda, as an essential active ingredient, a commercial item can be used as it is. The soil improvement material can be used in a 0.5 to 20% solution, preferably in a 1 to 10% solution. If desired, inorganic ion exchangers can be blended 5 to 10 times the essential active ingredients, and microorganisms and organic materials can be blended 2 to 10 times, but without being limited to these blending ratios, and Not only in the form of a solution but also in the form of a liquid, it can be appropriately determined without being limited by these blending ratios.

Examples of soil conditioners that use only essential active ingredients include 3 to 6% aqueous solution in which polyacrylamide is added to water. When other ingredients are blended, each ingredient is blended in the following amounts. In addition, a preparation prepared by adding water to 1 L is exemplified: Iwamilite (zeolite based on clinoptilolite) 100 g, SNKD bacteria (Bacillus polymixer IFO 3020, Pseudomonas fluorescens IFO 3081, Aspergillus ustus IFO 4104 10 ⁷ cells / g or more of each active cell mixture: Matsumoto Institute for Microbial Research) 80 g, 80 g of bark compost of fish carp and persimmon, and 1 L of water suspension of 40 g of polyacrylamide.

  Mineral refers to a trace element, for example, at least one selected from iron, copper, zinc, boron, manganese, molybdenum, and may include at least one of iodine, sodium, potassium, magnesium in addition to the above. In addition, it is preferable that a trace amount of an ultra trace mineral such as selenium or vanadium is included. These minerals may be formulated as mineral agents.

  As the mineral agent, those obtained by appropriately selecting and blending these minerals can be used. As the mineral agent, for example, the following metal salt solution can also be used. Ferric nitrate 0.08%, copper nitrate 0.05%, zinc nitrate 0.05%, ammonium molybdate 0.07%, manganese sulfate 0.1%, boron 0.2%, precipitation inhibitor 3%, 96.45% water.

  In addition to the above, the mineral agent can be prepared in various ways with reference to the above formulation. For example, 0.05 to 5.0% (0.1 to 3.0%) manganese, 0.1 to 3.0% boron as a mineral component 4.0% (0.2-1.0%), iron 0.02-7.0% (0.08-4.1%), copper 0.01-1.0% (0.05-0 0.5%), 0.01-4.0% (0.05-3.0%) zinc, and 0.005-0.5% (0.01-0.07%) molybdenum. The thing (the inside of a parenthesis is a suitable area) is illustrated. Moreover, as a mineral agent, various commercial items can also be used suitably, for example, nitrogen (0-7%), phosphoric acid (5-10%), potash (3- 9%) or “Minepower” containing 0.5 to 2% nitrogen in the above mineral components (both are products of Eisai Seikaken Co., Ltd.) ) And the like can be used as appropriate, and the solid preparation may be formulated in a liquid form as desired.

  If the mineral contains an ultra-trace mineral such as selenium or vanadium, only the application of the mineral may be used, but when an ultra-trace mineral application is desired and / or no ultra-trace mineral is contained In some cases, “ultra-trace minerals” that are much smaller than the above minerals can be used and blended separately.

  The ultra trace mineral refers to chrome, cobalt and other ultra trace minerals in addition to selenium (preferably vanadium), and is supplied as an ultra trace mineral agent containing this. As an ultra trace mineral agent, bitter juice (bitter melon) is suitable, and particularly high selenium (preferably higher vanadium) -containing bitter juice is preferred, for example, 1.0 to 5.0 ppm (preferably 1. 5 to 4.0 ppm), and bitter juice containing 1.0 to 5.0 ppm of vanadium are preferred.

  As an ultra-trace mineral agent, a selenium-containing mineral composition is suitable, for example, Chinese high selenium-containing natural bitter ("Green Safe": commercially available from Eisai Seikagaku Co., Ltd.) can be used. The component analysis values are illustrated in Table 1 below.

  Minerals (as well as ultra-trace minerals) can be formulated as mineral agents as described above, but these contents can also be used, for example seawater, salt water, ocean Deep water, hot spring water, mineral water, mineral water, bitter juice, etc. can be used.

  If necessary, a fertilizer component (at least one of nitrogen, phosphoric acid, and potassium) is further blended. As the fertilizer component, a commercially available blended fertilizer can be used as appropriate. Usually, liquid fertilizer is used, but even solid fertilizer may be dissolved in water to form liquid fertilizer. If such agricultural and horticultural materials are applied, in that case, a large amount of essential elements (nitrogen, phosphoric acid, potash) will be fertilized. Since it is in a state, it is preferable to lower the level until it reaches the reference value (FIG. 1). In this case, for example, the nitrogen component can be easily removed if it is in a flooded state, and fertilization may be suppressed or stopped until phosphoric acid and potassium reach a reference value.

  Each material according to the present invention is preferably used as a liquid. Further, if desired, the active ingredient may be prepared according to a conventional method for formulating an agrochemical formulation. For example, a carrier, a surfactant, a dispersing agent or an auxiliary agent and the like are mixed in a conventional manner, for example, a powder. It is more preferable to formulate and use in the form of wettable powder, emulsion, flowable powder, granule and the like. Suitable carriers include, for example, solid carriers such as clay, talc, bentonite, diatomaceous earth, white carbon, kaolin, vermiculite, slaked lime, silica sand, ammonium sulfate, urea, etc. Examples of surfactants and dispersants include alkylbenzenesulfonic acid. Examples thereof include metal salts, polyoxyethylene alkyl aryl ethers, sodium alkyl sulfates, sodium alkyl naphthalene sulfonates, sodium dinaphthylmethane disulfonate, and sodium lignin sulfonate. Examples of the adjuvant include carboxymethyl cellulose, polyethylene glycol, gum arabic, starch, lactose and the like.

  In addition, although the dosage form which is not liquid is illustrated above, if it is set as a solution, a suspension, and an emulsion, it can be used as a material according to the present invention.

  In the present invention, each material is applied in a necessary amount when necessary, and all these materials may be mixed and prepared and formulated into “agricultural and horticultural materials”. In addition, prepare each material (soil improvement material, mineral, ultra-trace mineral) individually (prepared individually if necessary), and set them as a set Materials "kits can also be assembled. In the latter case, one or more necessary materials may be selected from the kit at the required time and applied, and at that time, the materials prepared at the time of use may be applied.

  This material is applied to the soil using an infusion machine or an irrigator, but can be diluted as appropriate, or the active ingredient can be applied directly or as it is without dilution. For example, a commercially available product is directly applied to the soil conditioner and mineral agent, the ultra-mineral mineral agent is diluted 100 to 3000 times, preferably about 400 to 2000 times, and the liquid fertilizer is 100 to 3000 times, preferably 100 to 500 times. Although it can be applied after being diluted to about twice, it is not limited thereto.

  In the present invention, a certain composition of agricultural and horticultural materials is prepared in advance and applied in a necessary amount at a necessary time, or a necessary amount is applied at a necessary time by changing the composition, or The materials constituting the agricultural and horticultural materials can be combined in one or more kinds and applied in a necessary amount at a necessary time. Further, as described above, it is also possible to prepare an “agricultural and horticultural material” kit in which each material is prepared and combined into one set.

  Although this material may be applied to the soil surface, it is effective to apply it inside the soil. There is no particular limitation on the application depth, but it should be a relatively hard layer (including bedrock) existing under the cultivated soil layer or the vicinity thereof, usually 10-60 cm, preferably 30-40 cm deep from the ground surface. Let's say that.

  The material may be applied to the base of tea tree (that is, tea tree), but is preferably applied to a remote place. The application site is preferably separated from the tea tree, for example, 1 to 5 times or more, preferably about 3 times the diameter of the trunk from the center of the tea tree, and as close as possible to the root hair that absorbs nutrients. Location is preferred. For example, the irrigation is performed at a point 1 to 5 times or more (for example, 30 to 50 cm) away from the center of the tea tree (tea tree) at a depth of 10 to 60 cm, preferably 30 to 40 cm from the ground surface. be able to.

  In actual application, the present material can be applied in the form of a strip to the whole or a part of the surrounding area of a plant such as a tea tree (tea tree). It has been found that it is only necessary to irrigate a certain point in the form of dots. Moreover, although it has been found that one point is sufficient, it is more effective if irrigated in the form of dots at intervals of 10 to 50 cm, preferably about 30 cm. For irrigation, if this material can be liquefied using an irrigator or an infusion machine, it can be injected into the required location with air in a dot-like manner, saving labor, excellent workability, and labor and muscle strength are not required. Even seniors and women are excellent at being able to work easily.

  Commercially available products can be used as the irrigator and infusion machine as appropriate. However, if the following new type of irrigator is used, further labor saving and efficiency can be achieved (FIGS. 2 and 3).

  This irrigator closes the tip 5 of the pipe P, provides one to several ejection openings 6 on the upper part thereof, provides a liquid material supply device having opening and closing devices 3 and 7 on the opposite side of the pipe, On the way, it is composed of an air inlet 4, an adjustment tool 2 and a holding tool 8 (FIG. 2).

  The tip 5 may be simply closed at the tip of the hollow pipe P, but is preferably closed in a conical shape or various pyramid shapes so as to easily enter the soil. The liquid material supply device includes a hose (not shown) connecting portion 1, a lever 7, and a lever lock device 3. The hose connecting portion 1 is provided with a return 9 for preventing hose twisting. The air suction port 4 may be simply opened, or may be connected to an air pump so that air can be forcibly supplied.

  Although the usage mode of this irrigator was shown in FIG. 3, more specifically, the depth of injection | pouring is adjusted and fixed with the screw of the adjusting tool 2, and the pipe P is inserted in soil. At that time, the irrigator is inserted into the soil up to the position of the adjuster 2, but in the case of hard soil, the foot is stepped on the protruding portion of the adjuster 2 (FIG. 3). Fix and set the irrigator in this way.

  The connecting portion 1 is connected to a moving spray or an SS hose (not shown). The material stored in the tank is fed to the hose by the action of the pump. Therefore, when the lever 7 is held, the material flows into the pipe P and is ejected from the opening 6 into the soil. At that time, air is also sucked from the air inlet 4 and the air is also ejected into the soil. The opening / closing device 3 is also a lever locking device, and is another device for operating the lever 7. When the lever 7 is squeezed and the lever of the opening / closing device 3 is locked, this material is continuously ejected and the lever 7 is If you hold it again, the lock is released and continuous jet stops. Further, for example, if the left hand is placed on the holder 8, the work becomes easier (FIG. 3).

  According to the irrigator, for example, the following discharge amounts are obtained, respectively.

  As mentioned above, although the case where the material which concerns on this invention is applied to a tea tree has been described, this material can be widely applied to vegetables and other plants including fruit trees, root vegetables, fruit vegetables, leaf vegetables in addition to tea trees. However, this material has a remarkable effect that it is very effective even for plants with deep roots. Conventional agricultural and horticultural materials often did not reach deep roots, but the materials according to the present invention are used for root vegetables such as burdock, yam, carrot and radish. Is also effective. Moreover, this material is effective not only for root vegetables but also for tea, tomatoes and fruit trees.

  By applying the material according to the present invention, pest control action, plant growth promotion action, mineral balance (constancy) maintenance improvement action in soil and crops, fruit sugar content increase action and / or umami and richness It is distinctive in that it can improve the quality of various agricultural products such as enhancing effects, and it also improves the mineral balance in crops rather than acting directly on pests and pathogens and killing them like agricultural chemicals. By making this into a healthy body, it is completely epoch-making in that it indirectly exhibits the above-mentioned actions. That is, the agricultural and horticultural materials according to the present invention are very characteristic in that they are completely different in type from agricultural chemicals, fertilizers, plant growth regulators and the like.

  The detailed mechanism of the above action by this material must be studied in the future, but at present, by irrigating this material deeply into the soil, the hard soil layer is first aggregated by the soil conditioner and the root It is presumed that each of the above-mentioned actions is achieved by vigorous growth and the action of minerals and trace minerals there.

  As is apparent from the examples described below, the tea produced from the tea tree obtained by cultivation in this manner has greatly increased various amino acids such as Asp, Ser, Glu, Ala, and Arg in the irrigation zone. In addition to being extremely outstanding, what is even more noteworthy is that it is very characteristic in that theanine, which is an umami component peculiar to tea, has reached three times or more. From these analysis results, it can be seen that the tea in the irrigated area has excellent flavor, and both umami and richness are outstanding.

  In addition, tea in the irrigated area has also greatly increased catechins and caffeine content. In this respect, as is clear from the examples described later, it should be clearly confirmed even in the form of powdered green tea and the like. Can do.

  Moreover, the present inventors found for the first time that the tea according to the present invention can obtain an excellent hair nourishing effect by orally administering tea leaves in powder form, and as a result of further research, the tea powder was used as an active ingredient. An invention relating to a hair nourishing agent for oral administration (or hair nourishing tea) has been completed.

  As the powdered tea, after making tea using the tea leaves obtained by the cultivation method according to the present invention, the powdered tea may be pulverized with a stone mortar, ball mill, jet mill or other pulverizer. In addition, powdered tea can be used as a powdered tea. In this case, tencha is produced using tea leaves obtained by cultivation according to the cultivation method (provided that the light source is interrupted) as raw materials, and this is ground with a stone mill to make matcha tea. Except for using tea leaves cultivated in, the usual method for producing Tencha and Matcha may be used.

  There is no particular limitation on the particle size of powdered tea (including matcha, hereinafter the same) as long as it can be smoothly administered orally. In the case of a grinder, the volume-based average particle size is 1 to 100 μm, usually 20 to 50 μm. However, the matcha green tea ground with a good texture and flavor is distributed over a wide range from 1 μm to several hundred μm, and the particle size may be determined appropriately within these ranges. In the present invention, especially for the purpose of hair restoration, the tea itself is drunk or edible rather than the tea leaching solution. For example, large particles exceeding the above particle size range may be used, or the leaves themselves or chopped ones may be used.

  Powdered tea (sometimes called mineral tea or mineral matcha) may be orally administered about 1 to 3 times a day after suspending about 5 to 15 g in 100 to 200 ml of water. Of course, powdered tea may be directly orally administered without oral administration with water, hot water, milk, juice or other liquids. Usually, water or hot water may be added to powdered tea, stirred well, and drunk in the same way as normal tea.

  In addition, if desired, powdered tea with other additives suitable for oral administration can be converted into powder, paste, tablet, granule, capsule, liquid food and drink or pharmaceutical form by conventional methods. Can do.

  The powdered tea according to the present invention has excellent hair-restoring effects such as promoting hair growth, increasing hair amount, reducing white hair, and increasing black hair by orally administering it, and is a tea. There is no problem in safety even if taken for a long time, and it is delicious as tea, and it is very easy to take. In addition, it can distinguish from the powdered tea used for normal drinking by using powdered tea as an active ingredient, and making it the powdered tea which attached | subjected the indication to be used for hair nourishment. It can be said that the present invention forms a new application invention.

  In accordance with the present invention, by applying materials such as soil improving materials, minerals, ultra-trace minerals, and further materials such as compost components and fertilizer components as necessary, useful effects such as plant growth and quality improvement can be obtained. In particular, this action is characteristic in that it is further enhanced by irrigating deep in the soil, and without using pesticides or plant growth regulators, etc. The present invention is also excellent in that the material is a natural material. At that time, we investigated and analyzed the cultivation soil of tea trees, and with reference to Fig. 1, if each material was applied, the cultivation of better tea trees was performed, and better tea leaves were obtained. By making tea, tea with excellent flavor and quality can be obtained.

  In addition, according to the present invention, an excellent hair nourishing effect can be achieved by orally administering it as powdered tea. As the demonstration, FIGS. 8 to 11 (drawing substitute photos) are shown. As the powdered tea, the best tea obtained in the example was used by using a tea mortar in the same way as matcha tea, and the powdered tea was put in a teaspoon (about 5 g) and suspended in 100 ml of hot water. In the same manner as normal tea, after drinking every day, after waking up, and at bedtime, 5 times before drinking, as seen from the photograph in FIG. 8 after 10 months, before drinking (1995, 75 years old) Compared to), there is a clear increase in black hair. Since then, as is clear from the photographs in FIGS. The effect of the fact that the hair and black hair increase by drinking the powdered tea according to the present invention is actually shown in the figure, while the hair is usually reduced with age and the black hair is also reduced. It can be said that the effect is greatly exceeded. Therefore, the present invention also provides excellent hair nourishing tea.

  Examples of the present invention will be described below, but the present invention is not limited to the examples.

  The Example about the hair nourishing effect by the powdered tea manufactured from the cultivation method of the tea tree by this invention and the tea leaf obtained by cultivation as a raw material is shown.

The growth of the tea plant on July 31 is shown in FIG. 4 (the upper row is the upper row).
FIG. 5 is a photograph of this taken from a different angle, and the lower part is an upper part. FIG. 6 is a photograph of the tea plant in the control ward, with the lower row being the upper row.

  As is clear from these results, the tea in the soil irrigation treatment group had better buds, thicker leaves, and larger leaves (the most tea: one tea), and even more in comparison with the control group. In contrast, the control tea had poor buds, small leaves, sparseness and irregularity.

  When tea was made with the picked tea, all the teas showed good flavor. However, as a result of the panel test, it was found that the shorter the days until tea picking after irrigation, the better the flavor.

  In addition, tea was made using irrigated tea and the components of the obtained tea were analyzed (November 28, 2003). The results are shown in Table 4 and FIG. In addition, the analysis result of the commercial item was also shown as a control plot.

  Moreover, tea was made using Nibancha (Nicha), and the components of the obtained tea (mineral) were analyzed (Table 5). As a control, the results of analysis of commercial products are also shown. In the measurement, 0.5 g was immersed in 50 ml of water, placed at 80 ° C. for 30 minutes, and the filtrate was measured (concentration of a solution in which 1 g of tea leaves were placed in 100 ml of water). Furthermore, Table 6 shows the results of test results for each component.

  As is clear from the above results, the irrigation section is extremely excellent even when the various amino acids are greatly increased, but it should be noted that theanine, which is the umami component of tea, is 3 for the most tea. It is very characteristic in that it reaches more than double. From these analysis results, it can be seen that the tea in the irrigated area (mineral area) has excellent flavor, and has excellent umami and richness.

(Example 2)
In Example 1, the same treatment as in Example 1 was performed except that the light beam was interrupted during the first tea cultivation, and tencha was produced using the socks tea leaves as a raw material in the same manner as Gyokuro. Then, this tencha was drawn with a stone mill (tea mill) in accordance with a conventional method to produce matcha (mineral matcha).

  About the obtained matcha, catechins and caffeine were measured. The measurement was performed by immersing 0.5 g of matcha in 25 ml of 2% phosphoric acid solution for 5 minutes and then immersing in 25 ml of ethanol for 40 minutes (concentration of the filtrate obtained by immersing 1 g of tea in 100 ml of the solution). Table 7 shows the obtained results. Tencha (boiled tea) is a tea from Shizuoka and is a contrast product of the present invention.
