DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to vegetables, fruits, cereals,
The present invention relates to an improved method for growing plants such as flowers, and more specifically, mixing a specific mineral composition in water at an appropriate concentration,
The present invention relates to a method for improving plant growth by using this as a fertilizer or a nutrient.

BACKGROUND OF THE INVENTION It is widely known that minerals are more or less contained in plants. These minerals are thought to be important substances for the growth of plants and for maintaining the life of the plants themselves.However, compared to the recognition of their importance to humans, there are still many unknowns and little research results. Is the current situation. On the other hand, in recent years, the recognition that minerals contained in plants are important as nutrients for humans has been gradually increasing, and at the same time, research results supporting this fact have been increasing. In addition, it has been increasingly recognized that minerals in plant bodies not only position themselves as nutrients but also affect taste. However, on the other hand, there has been an increasing tendency to point out that ingredients such as vegetables that are distributed in the market have no longer tasted like they are. It is also considered that minerals contained in foodstuffs decreased due to the spread of hydroponic cultivation and the spread of processing techniques such as rice milling. Naturally, the earth is rich in minerals, but in a situation where agriculture is highly concentrated and continuous cropping is performed,
It is considered that minerals originally contained in the earth have disappeared compared to a year ago, and that nutrient elements contained in the earth are basically missing in hydroponic cultivation. Grains, vegetables, fruits, flowers, etc. that grow in such a situation naturally contained ingredients changed from a year ago, and the taste was worse,
It seems that the situation is unavoidable. in this way,
Only a few organic methods exist to correct the shortcomings of currently growing plants such as vegetables. However, this method simply reverts to the old cultivation method, and does not seem to necessarily suggest a future agriculture in view of productivity, color and shape and other merchantability. Efficient growth, high nutritional value, good taste, and safety are key keywords for future agriculture. An object of the present invention is to provide a method for growing a plant such as a vegetable having high nutritional value and excellent taste while enhancing productivity.

The inventor of the present invention has made intensive studies to solve the above problems, and as a result, completed the present invention. That is, at least sodium, calcium,
In the mineral composition containing the four minerals of magnesium and potassium, the amount of sodium is 1/50 to 1/3 of the total amount of the other three minerals, ie, potassium, magnesium, and calcium (all the amounts of sodium (weight ) Is set to 1) and potassium
With respect to magnesium and calcium, when the minimum component amount is in the range of 1/6 (the minimum component amount is 1) to 1/1 of any of the other two components, the mineral composition (A) with a sodium concentration of 0.0005 to
A 5% amount is mixed with water, the mixture is used as a fertilizer or a nutrient, and the mineral composition A is adjusted to a sodium concentration, and 0.0005 to 5% is mixed with water to be used for hydroponics. At this time, they found that the color, shape and taste of the plant collected after growing the plant were significantly improved, and completed the present invention. Hereinafter, the present invention will be described in detail.
It is widely known that minerals are contained in many plants and play an important role in maintaining the life of animals including humans. However, little is known that minerals are important for plant growth, except for a small amount of potassium. Therefore, there is no product that has been put to practical use based on the results of this type of research. The present inventor focused on four types of minerals present in relatively large amounts among mineral components. As a result of comparison from the viewpoint of improving the growth, the mineral-containing mineral composition was found to have a higher water content than the non-added one, and the apparently quantitatively balanced mineral composition was better than the poorly balanced composition. It was found that it was effective in improving the growth of plants in tillage and land. At present, most commonly available mineral compositions are those in which the above four kinds of minerals, ie, sodium, potassium, magnesium, and calcium, contain a large amount of protruding magnesium, or those in which a large amount of calcium protrudes. is there. The shelf life improvement of cut flowers, vegetables, fruits, etc. is clearly improved when compared with the case where they are not added, but when compared with a mineral composition with a good quantitative balance of minerals, the latter effect is clearly apparent. Was excellent.
That is, in a mineral composition containing at least four minerals of sodium, calcium, magnesium, and potassium, the amount of sodium is 1/50 to 1/3 of the total amount of the other three minerals, ie, potassium, magnesium, and calcium. (The sodium content (weight) is assumed to be 1), and the minimum component amount of potassium, magnesium, and calcium is 1/6 (minimum) of any of the other two components. When the amount of the component is 1) to 1/1, the mineral composition (A) has a sodium concentration of 0.0005 to 5%.
When the amount is mixed with water, the mixture is used as a fertilizer or a nutrient, and when the mineral composition A has a sodium concentration of 0.0005 to 5% and is mixed with water for use in hydroponics, It has been found that the color, shape and taste of the plant collected after growing the plant are significantly improved. In this case, with respect to sodium, the presence of an excessive amount adversely affects the plant cells, so that the above-mentioned quantitative limitation range of sodium was set. On the other hand, when preparing these mineral compositions, rather than artificially using mineral or organic substances containing minerals, it is necessary to perform as much artificial manipulation of the raw materials as possible from natural products. It is needless to say that it is desirable to prepare. This is because mineral substances are nutritional substances, and these nutritional substances including mineral substances have been taken from the natural world in the history of mankind, and ingestion from natural products is closer to nature. In particular, regarding seawater, it is natural that all living organisms have origins in the sea, and that the components of seawater itself approximate or include the nutrient components and body fluid components required by living organisms. It can be said that. The present inventor has found that when the mineral component of seawater is rich in minerals required for human living organisms, and when salt is removed from seawater under specific conditions without impairing other mineral components as much as possible, It has been found that a mineral composition substantially equal to the mineral composition of the present invention can be obtained, thereby completing the present invention. In addition, regarding the method of removing salt from seawater, there is no basis for limiting to a specific method, and any method may be adopted.
Generally, a method is employed in which seawater is concentrated using sunlight or an ion exchange membrane, and salt, which is the largest component in the seawater, is precipitated from the seawater by a dehydration operation or the like.
It is not necessary to limit the method of deletion to this method. In other words, there is no problem to adopt a method that utilizes a substance that selectively reacts with and takes in sodium in salt or a method that utilizes a substance that selectively takes in sodium electrically. . In this case, the amount of salt to be deleted is 30 to 95%, preferably 40 to 90% of the original salt amount. Note that it is strictly impossible to delete only salt and it depends on the method of deletion.
Normally, other minerals are also deleted when the salt is deleted. Of the remaining minerals, potassium, magnesium, and calcium require that the minimum amount of minerals be in the range of 1/6 to 1/1 with respect to any of the other minerals. When this condition is satisfied, it is clear that the balance of the mineral composition substantially maintains the balance required for the living body. Further, in order to make the mineral balance more accurate, two or more kinds of mineral compositions prepared by variously changing the conditions for removing salt may be mixed in an appropriate amount to prepare a mineral composition. on the other hand,
Whether the mineral composition is a liquid, a solid or a powder, its form need not be limited. In short, any composition that satisfies the conditions described in the above claims may be used. Further, the concentration of the mineral composition is not limited to any particular concentration, but is preferably in the range of 0.01% to 10% in terms of sodium concentration. The mineral composition according to the present invention may be used alone, or may be used by adding to other nutrients, fertilizers and additives. Conversely, other nutrients, fertilizers, additives, and some of these may be added to the mineral composition for use. Further, as a method of mixing the mineral composition with other nutrients and fertilizers, a method of mixing the mineral composition with other nutrients and fertilizers in a liquid state and drying if necessary, or a method of mixing the mineral composition There is a method of mixing with other nutrients and fertilizers by granulating or pulverizing. In this case, it does not matter whether other nutrients or fertilizers are solid or liquid. Also, in the step of granulating other nutrients and fertilizers, spraying the mineral composition alone or with water or a binder, or granulating alone or with water or a binder as a binder during granulation, Alternatively, other nutrients and fertilizers can be coated with the mineral composition. In addition, the nutrient composition may be coated with other nutrients or fertilizers. The mixing ratio of the mineral composition to other nutrients and fertilizers is not particularly limited.

EXAMPLES Next, the present invention will be described in detail with reference to examples, but the present invention is not limited to the following examples unless it exceeds the gist.

Example 1 Seawater is concentrated to a salt concentration of about 18%. The seawater solution is boiled down to precipitate and remove salt. In this case, when the salt concentration becomes about 5%, the precipitation / deletion of the salt is stopped. Mineral components of the residual liquid were analyzed and the results are shown in Table 1. From the results shown in Table 1, a concentrated mineral composition having a good mineral balance was obtained by this operation.
This mineral composition was designated as A. On the other hand, the amount of magnesium is about 20 times less than the amount of sodium, potassium and calcium.
The mineral composition containing twice the amount was designated as B. A and B are added to tap water so that they have almost the same concentration (for tap water, A,
B was added at 1% in both cases, and tap water alone was designated as C). Then, seedlings of salad greens were immersed in each of A, B, and C, and the state of growth was observed with time. As a result, in the non-added group, C reached the growth peak 15 days later, whereas B reached the growth peak 14 days later and A reached the growth peak 10 days later. In addition, the state of leaves of salad rape at the growth peak is better in A and B than in C,
-In comparison with B, A was better. On the other hand, as a result of eating these salad vegetables, the taste of A and B was better than that of C, and the taste of A was better than that of AB. As described above, when A having a good mineral balance was used, the color, shape and taste of the leaves of the vegetables collected after the growth were all good, and it was recognized that the effect of improving the growth was remarkable.

[0007] The mineral composition obtained in Example 1 is A, as compared calcium weight sodium-potassium Sei-time amount of magnesium 2
The mineral composition containing 5 times the amount was designated as D. A and B were added to tap water so that the concentrations were almost the same (1% of A and D were added to tap water, and C was tap water only). C. The radish seedlings were immersed in each of C for 20 days, and the state of growth was observed over time.
As a result, C in the non-added group reached the growth peak after 20 days, whereas B reached the growth peak after 19 days and A reached the growth peak after 14 days. Also, at the growth peak, the state of the leaves of the radish was higher in A and D than in C, and in A and D, A was better. on the other hand,
As a result of eating these radishes, A, D compared to C
Was superior in taste, and A was better in comparison of A and D. As described above, when A having a good mineral balance was used, the color, shape and taste of the leaves of the vegetables collected after the growth were all good, and it was recognized that the effect of improving the growth was remarkable.
