DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for improving soil such as turfgrass to protect plants such as turfgrass from diseases.

[0002]

2. Description of the Related Art In order to protect turfgrass from disease, daily prevention is an important point. Causes of diseases such as turfgrass include the nature and physiology of pathogenic bacteria,
Obstacles due to acidic environment, drainage due to soil environment, obstacles due to excess water, and the like. This will be briefly described.

Nature of Pathogenic Bacteria and Physiology for Sterilization 20% of turfgrass diseases are caused by bacteria.
In general, diseases caused by soil-borne fungi (molds) are the mainstream at 80%. These pathogens include "saprophytes that feed on lifeless organic matter" and "companies of Pishum and Rhizoctonia that grow on fresh organic matter while competing with saprophytes and infest a wide range of plants." There are two types.

[0004] As a form of transmission of these pathogens to turfgrass, scattering of spores by wind, scattering and migration of spores by rainwater or watering, and the like can be considered. Utilizing turfgrass, which is a new organic matter, the infectious fungi that multiply and spread by turfgrass are scattered and transmitted to the turfgrass. For 2 hours, the bacillus emerges within 8 hours and grows, creating vegetative forms of filamentous bodies.

Nutritional pathological complex disorders The occurrence of diseases caused by fertilizer, which is a nutrient source, is caused by excess nitrogen and potassium deficiency although there is a time problem.

When an organic substance rich in water-soluble sugars such as green vesicles such as fresh organic substances (including turfgrass residues) is applied, the filamentous fungi (Pishum fungi) grow rapidly using the water-soluble sugars. Come. Pishum bacteria in the soil endure with large spores of thick spores of oospores, but germinate in response to water-soluble sugars, enter radicles and necrotize the roots. It is also known that excessive use of nitrogen fertilizer is intensified.However, heavy use of nitrogen fertilizer makes the cell membrane of plants thinner, and at the same time reduces the silicic acid content, which is a factor in the hardness of turfgrass, causing bacteria to grow in turfgrass. Easier penetration of epidermal cells results in faster disease progression.

[0007] Disorders caused by acidic environment [0007] Fusarium bacteria, Rhizoctonia bacteria, and the like are pathogenic bacteria that flourish in acidic soil. In the case of sclerotium disease, the degree of disturbance varies depending on the type of fertilizer applied. For example, the degree of disability is different, for example, the disease is intensified by the application of ammonium fertilizer, and is somewhat alleviated by nitrate fertilizer. The general behavior of pathogenic bacteria is severe in acidic soils. This is because the spores of the pathogenic bacteria germinate due to the acidic sugar component and have the property of being able to live longer in acidic soil than in alkaline soil.

[0008] From the viewpoint of drainage due to the soil environment and pathology caused by excessive water, from the viewpoint of pathology, spores are unlikely to propagate unless the water content is excessive, and survive in the soil in the form of chlamydospores (oospores) as a durable body. are doing. But,
If the water content is too high, it will germinate in the same way as plant seeds and will grow violently.

[0009] As described above, plant diseases are composed of the following items which cause the lowest occurrence.

Conventional turfgrass management includes physical management such as low cutting, treading, flooding, and soil, and chemical management such as fertilizer, soil improvement, and pesticides.

[0011]

By the way, in crops and the like, soil can be digged after harvesting and the soil can be improved by spraying a soil conditioner or the like. There is a problem that it is likely to remain and become obstacles for continuous cropping. Also, turfgrass cannot be cultivated, so that pesticides and soil conditioners are sprayed more than necessary. As a result, nutrient accumulation, trace metals (calcium,
(Magnesium, potassium, etc.) has appeared, and the appearance of acidic soil has been observed, which has the problem of promoting growth disorders and diseases.
Also, turfgrass growing, which has been considered to be prevented by fertilizers and pesticides, has a problem that even the soil disinfection effect is eventually reduced.

Accordingly, an object of the present invention is to solve the above problems and to provide a method for improving soil such as turfgrass, which can effectively improve soil.

[0013]

In order to achieve the above object, the invention according to claim 1 of the present application is to provide a method for electrolyzing water in an electrolytic cell to generate acidic water and alkaline water, It is characterized in that treated water composed of water and treated water composed of acidic water and treated water composed of alkaline water are alternately sprayed on soil in which plants such as turfgrass are planted. The invention according to claim 2 of the present application electrolyzes water in an electrolytic cell to generate acidic water and alkaline water. Plants such as turfgrass are planted together with fertilizer and treated water comprising the acidic water or alkaline water. It is characterized by being sprayed on the soil obtained.

[0014]

According to the above construction, by treating the soil with treated water comprising acidic water and alkaline water, the pH of the soil is reduced.
Can be adjusted freely, and because it is easily decomposed, it can be improved without remaining in the soil

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

First, as the treated water composed of oxidized water or alkaline water, Japanese Patent Application No. 63-51765 and Japanese Patent Application No. 63-1
Oxidized water from the anode compartment and alkaline water from the cathode compartment proposed in US Pat. That is, this oxidized water or alkaline water separates the inside of the electrolytic cell into two chambers with a diaphragm, and provides electrodes in both chambers and connects them to a DC power source to form an anode chamber and a cathode chamber. By supplying water containing a saline solution as an electrolytic solution to the chamber and performing electrolysis, acidic water is generated from the anode chamber, and alkaline water is generated from the cathode chamber, and these are taken out and used.

As the treated water, acidic water has a pH of 2.7 or less,
Bactericidal properties can be obtained by using alkaline water having a pH of 11.0 or more. Acidic water has active chlorine 30 ppm, dissolved oxygen 25 ppm, the properties of the redox potential 1,100MV, alkaline water is added an alkali metal such as KOH, OH ^- and property of binding with the hydrogen ions by active oxygen It has properties of 8 ppm and a redox potential of -920 mV.

Table 1 shows the results of a sterilization test at each pH of the treated water. Pichium, Rhizoctonia and Fusarium were used as the measuring bacteria, and the contact time was 5 minutes.
The sensitivity was measured in (+-) as minutes. In this case, + indicates no sensitivity and-indicates sensitivity.

[0019]

[Table 1]

From the table, it is shown that the pH of Pishum bacteria is 2.7 or less and the pH of 11.0 or more.
0 or less, pH 11.0 or more, for Fusarium bacteria, pH
It is sensitive at a pH of 3.0 or less and a pH of 11.0 or more, and a bactericidal effect is obtained.

Next, FIG. 1 shows the result of an experiment for improving soil pH using sea sand and black soil.

In this test method, 1 kg of sea sand of pH 9.22 and 1 kg of black soil of pH 5.35 were prepared, and 0.5, 1, and 2 liters of oxidized water (pH 2.65) was contained in the sea sand. The change in pH was measured. For black soil, alkaline water (pH 11.5) was set to 0.5,
The change in pH was measured for one or two liters. As can be seen from FIG. 1, the pH range in which plants can grow properly by adding treated water to both sea sand and black soil (5.
7 to 6.8).

From FIG. 1, it is considered that the pH of the sea sand drops rapidly with 0.5 liter of oxidized water, but since the sea sand contains no organic matter, it does not have a buffering action and drops. In addition, black soil has a large amount of organic substances, so that the pH is moderately increased due to the buffer action. Three types of sea sand and black soil and a mixture of sea sand and black soil were put into a planter, bentgrass was planted, and cultivated for about one year. The growth was good, and the pH of the soil was pH 6.5 to 6.5.
It stayed within the range of 7.01.

Next, an experiment was conducted using a bent glass to examine the effect of spraying oxidized water and alkaline water.

First, the bentgrass grown was transplanted to a planter using sandy soil, sprayed daily at a spraying rate of ² L / m ² (converted amount), and subjected to an experiment for 3 months. The experiments consisted of (1) spraying tap water with no fertilizer, (2) spraying oxidized water with no fertilizer, (3) spraying chemical fertilizer and oxidized water, (4) spraying alkaline water with no fertilizer, and (5) chemical fertilizer. And 5 types of spraying with alkaline water.

As a result, as compared with (1), (2) showed a slight inhibition in the rhizosphere near the ring. The soil pH is 6.
It was 3. In (3), no inhibition was observed. This is probably because fertilizer has a buffering action. The soil pH was 6.7. (4) showed good growth and no inhibition was observed. The soil pH was 7.01. (5) showed good growth and no inhibition was observed. It was recognized that the rhizome was thick because of the good absorption effect of fertilizer. Soil p
H was 6.8.

As described above, there is no problem even if both oxidized water and alkaline water are sprayed alone. In practice, the oxidized water and the alkaline water are alternately sprayed, so that it is considered that there is no inhibition of root hair.

[0028]

In summary, according to the present invention, the pH of the soil can be adjusted and improved by spraying the treated water consisting of acidic water or alkaline water onto the soil of plants such as turfgrass.
