Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fungicide and a plant growth promoter used in agriculture and horticulture, and more particularly to a fungicidal plant growth promoter which is highly safe for humans and does not pollute the environment.

[0002]

2. Description of the Related Art In recent years, greenhouse cultivation of vegetables, flowers and the like, which can secure high profitability, has been actively carried out, and a continuous cropping of a single crop has become common due to a system for designating a vegetable producing area. In order to avoid obstacles caused by continuous cropping, it is difficult to rotate crops in the traditional way, and large amounts of pesticides have been used to overcome soil diseases and the like.
However, the use of pesticides is prohibited in hydroponics, and attempts have been made to overcome the diseases by devising cultivation methods. On the other hand, a large amount of pesticides are used for turf management at golf courses, which causes problems such as adverse effects on the environment and pollution of water sources at water purification plants.

Also, many fertilizers have been applied for the purpose of nourishing plants and increasing profits. However, most of the fertilizers applied are chemically synthesized, and if applied for a long period of time or in large amounts, they may remain in the soil and adversely affect the human body or become environmental pollutants. There is.

As a solution to this problem, it is preferable to replace the chemical fertilizer with an organic fertilizer or a fertilizer derived from a natural product. However, compared to chemical fertilizers, these have problems in stability of supply, slow-acting effect, and the like, and although they are highly safe to the human body, they are still environmental pollutants. Moreover, the use of pesticides is indispensable for disease control, and environmental pollution is inevitable. In addition, it is necessary to use a bactericide, especially in the case of vegetables to be eaten raw.

As described above, fertilizers as plant growth promoters used to nourish plants and increase profits and pesticides for overcoming diseases have various problems.

[0006]

SUMMARY OF THE INVENTION The object of the present invention is to solve such problems, to have almost the same potency and bactericidal activity as those of conventional plant growth promoters, and to improve plant growth. Root promotion, lodging prevention, yield improvement, green improvement, shortening of growing period,
Effective in controlling diseases and controlling various bacterial groups, in addition to
It is an object of the present invention to provide a bactericidal plant growth promoter and an application method that are extremely safe for the human body and do not cause environmental pollution.

[0007]

As a result of intensive studies, the present inventors have solved the above problems and completed the present invention.

That is, the present invention can be obtained from alkaline ionized water obtained from the cathode chamber and from the anode chamber by supplying tap water or mineral water to the electrolytic cell in which the cathode chamber and the anode chamber are divided by the diaphragm to electrolyze. A method for applying a bactericidal plant growth promoting agent, which comprises using acidic water as an active ingredient, and mixing or alternately sprinkling alkaline ions and acidic water.

As the electrolytic cell for obtaining the alkaline ionized water and the acidic water which are the active ingredients of the bactericidal plant growth promoter of the present invention, a commercially available domestic alkaline ionized water conditioner can be used. An electrolytic cell having a polarity reversal function for removing scale by hardness components such as calcium and magnesium attached to the cathode and the diaphragm is more preferable. Tap water is usually supplied to the electrolytic cell, but potassium chloride,
Mineral water containing several hundred ppm of an inorganic salt such as sodium chloride, sodium carbonate or magnesium chloride may be supplied.

As the electrode of the electrolytic cell, it is desirable that the produced alkaline ionized water and acidic water do not elute the metal which is a harmful component to plants. As the cathode of the electrolytic cell, stainless steel, titanium, etc. can be used, and as the anode, graphite, magnetite, platinum, lead, etc. can be used. However, considering the above points, the valve metal body can be electroplated or pyrolyzed. An electrode coated with a platinum-containing coating composed of at least one component selected from platinum group metals or platinum group metal oxides is particularly preferable because the metal does not elute even when polarity inversion is performed.

As the diaphragm in the electrolytic cell, a biscuit plate, a porous plastic or a fluorocarbon cation exchange membrane can be used. Among these, the biscuit plate is brittle and must be handled with care, and only a thick plate can be obtained, which is not preferable. A porous plastic or fluorocarbon-based cation exchange membrane is preferable because it has sufficient mechanical strength even if it is thin.

The bactericidal plant growth promoter of the present invention is used in place of or in combination with ground water or tap water that is usually used when watering plants.

Further, when it is used in combination with a liquid pesticide, another chemical fertilizer or an organic fertilizer, it further promotes growth and is more effective for disease control, and the fertilizer and pesticide can be greatly reduced. At the same time, the impact on environmental pollution can be greatly reduced.

The plants to which the bactericidal plant growth promoting agent of the present invention is applied include vegetables, flowers and the like, but plant garden vegetables such as tomatoes, eggplants, peppers and other solanaceous vegetables, cucumbers, watermelons, melons, squash, etc. Vegetables, strawberries, radish sprouts, bean sprouts, honeywort and the like are preferable. Among them, cabbage radish, bean sprouts, honeybee and the like which are germinated and ready to be eaten are particularly preferable because the growth promoting effect of alkaline ionized water is large. For vegetables such as cucumber, tomato, radish radish, and honeywort to be eaten raw, in addition to the disease control and growth promoting effects, the bactericidal effect of the edible portion with acidic water is very effective.

[0015]

The alkaline ionized water, which is one of the active ingredients in the bactericidal plant growth promoter of the present invention, is a weakly alkaline water rich in minerals necessary for plant growth and has a plant growth promoting action. The other active ingredient, acidic water, is weakly acidic water containing a trace amount of hypochlorous acid and has a bactericidal action. By mixing or alternately sprinkling acidic water and alkaline water on a plant, the plant growth promoting action of alkaline ionized water and the bactericidal action of acidic water can be simultaneously obtained.

The bactericidal plant growth promoter of the present invention is obtained by electrolyzing tap water or mineral water,
There is no concern about causing environmental pollution such as chemical fertilizers, organic fertilizers, fungicides or pesticides, and it is extremely safe for the human body.

By mixing or alternately sprinkling alkaline ionized water and acidic water, which are the active ingredients of the bactericidal plant growth promoter of the present invention, on vegetables, flowers, etc., plant growth promotion, collapse prevention, yield improvement, It is effective in improving green food, controlling diseases, and suppressing sterilization of various bacterial groups, and shortens the growing period.
