  However, the conventional farming method has the following problems in connection with the generation of two types of functional water of strong oxidation water and strong reduction water by the strong electrolyzed water generator having a diaphragm. That is, the farmer needs two water storage tanks, and it is necessary to spray two kinds of water, and the farm work is complicated.

  In addition, strong oxidizing water does not evaporate immediately when it is rained, cloudy, or at night, and causes defects such as acid burns or the inside of the sprayer not cleaned immediately after spraying. is there.

  Furthermore, when the pH and ORP (oxidation-reduction potential) values of functional water become abnormal or when stored for a long period of time, potassium hydroxide in strongly oxidized water generates potassium compounds and causes salt damage, while strong reduction Sodium hydroxide is generated in the water, causing crop burning and growth failure.

This reduces the complexity of farming operations due to stored water and sprayed water, and prevents the occurrence of oxidation of metal parts and salt damage caused by oxidized water, or the prevention of crop burning and growth damage caused by reduced water. A reduced water generating device, foliar spray water, soil irrigation water or soil irrigation water, and a crop cultivation method can be obtained.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings shown as examples. FIG. 1 to FIG. 3 are diagrams showing a first configuration, a second configuration, and a third configuration, respectively, as configuration examples of the electrolytically cultivated electrolyzed water generating apparatus of the present invention. FIG. 4 and FIG. 5 are diagrams showing pH change with time and ORP (oxidation-reduction potential), respectively, with respect to test results when electrolytically reduced water placed in a 20 l sealed container is allowed to stand at room temperature.

  The apparatus for producing electrolytic reduced water for crop cultivation according to the present invention comprises an electrolyzer having a diaphragm that includes an anode side electrode and a cathode side electrode.

Furthermore, it is preferable to provide an additive injection means for injecting an additive made of a synthetic compound.

  The circulation mechanism continuously or intermittently circulates water in a circulation path from the water storage tank to the water storage tank through the electrolytic cell. Thereby, the water in the water storage tank is repeatedly electrolyzed. As a result, the oxidation-type water becomes reduction-type water, and the reduction-type water becomes stronger reduction-type water having a stronger reducibility (that is, having a lower ORP (redox potential)), and thus ORP (redox potential). ) Electrolyzed reduced water of -100 mV or less is produced.

This is to generate reduced water (ORP = + 200 to −700 mV) in which the redox potential is changed by changing the additive mixed in the water to be electrolyzed and changing the electrolysis voltage according to the purpose of use. is there. Such devices use high-frequency AC voltage, the electrode plate is exposed, and safety is a problem. In addition, mixed water containing various additives such as ore, tourmaline, various organic minerals, and chitosan in the water This makes the work very complicated for the farmer and makes it difficult to manage the volume and concentration of the additive.

In addition, you may carry out manually or automatically as a means during application | coating of electrolytic reduction water, soil irrigation, and soil irrigation.

  In the cultivation method of the present invention, the electrolytically reduced water vigorously grows the roots of crops, so that the water and nutrient absorption of soil is improved, the growth of plants is promoted, and many anabolic nutrients are produced by photosynthesis. It has effects such as improving the growth of crops, increasing sugar content, improving taste, increasing yield, and extending the harvest period.

  When the electrolyzed reduced water generating apparatus for crop cultivation according to the present invention has the above-described structure, oxidizing raw water such as tap water and well water is supplied directly from the raw water supply unit 7 to the electrolytic cell 1 and continuously electrolyzed. can do.

<Electrolytically reduced water for crop cultivation>
The electrolytically reduced water for crop cultivation is neutral water that is almost the same as the pH value of raw water (pH = 7.2, ORP = 470 mV) (specifically, 6.5 to 8). Uses neutral reduced water in a reducing system having a redox potential ORP = 0 mV or less without stress such as acid burn due to strong alkalinity or sodium hydroxide damage. However, the optimum ORP (redox potential) is −100 to −200 mV.

  As shown in FIG. 4, when the electrolytically reduced water for crop cultivation is stored in a closed water storage tank 5, the pH value tends to be slightly alkaline but hardly changes.

  As shown in FIG. 5, when the electrolytically reduced water for crop cultivation is stored in a sealed water storage tank 5, ORP (oxidation-reduction potential) gradually rises with time and goes from the reduction system to the oxidation system.

  Therefore, it is desirable to use the electrolytically reduced water for crop cultivation with the oxidation-reduction potential ORP = 0 mV or less, that is, the electrolytically reduced water within 5 days after generation in the electrolytically reduced water device for agricultural crop cultivation. As can be seen from the results of the electrolyzed water cultivation test for the agricultural products in the attachment, it can be seen from the cultivation comparison test of electrolyzed reduced water (ORP = 62 mV) left at room temperature for a week and electrolyzed reduced water (ORP = -162 mV) generated during spraying If the electrolytically reduced water that has passed is used, effects such as the growth of crops and the sugar content are reduced. That is, it approaches the normal cultivation result using oxidizing water such as tap water.

  Cultivation of electrolytically reduced water produced at the time of spraying from electrolytically reduced water left at room temperature for one week, as can be seen from the results of house water tomato (ground cultivation) and house eggplant (ground cultivation) of the electrolyzed water cultivation test results of the attached crop , The average sugar content is higher by 0.3 to 0.7 degree.

<Cultivation method of crops using electrolytic reduced water for cultivation>
The electroreduction water in the water storage tank 5 generated by the electroreduction water generator for crop cultivation is sprayed on all the leaves and crops manually or automatically using a sprinkler, a power sprayer or other sprayer.

  The electrolytic reduced water produced by the electrolytically reduced water generating device for crop cultivation may be irrigated to the soil as irrigation or irrigation water while the electrolytic reduced water is sprayed on the leaves. Moreover, it is sufficient to irrigate the soil as irrigation water.

  What is cultivated using electrolytically reduced water is more effective than normal cultivation in all crops such as vegetables and fruits and all plants such as bonsai and planting.

  Spraying and irrigation of electrolytically reduced water to crops, etc. will take 3-10 days depending on the season and weather. However, the optimal interval is preferably one week.

The amount of irrigated water for crops, plants, and irrigation of electrolytically reduced water may be based on the amount of irrigation and irrigation conducted in normal farm work, but the amount of irrigation is 10 to 20 m ² / l and the amount of irrigation is 1 to 2 m. ^{As a} guide, ² / l. However, even if the amount of spraying and irrigation is somewhat high, there are almost no problems such as crop and plant growth except during the heavy rainfall season.

  If liquid fertilizer or herbal medicine is added to electrolytically reduced water and foliar spraying is performed as foliar spray water, it is expected to further increase crop yield and quality.

  From the above, it is more effective to use reducing electrolytically reduced water having a low ORP (redox potential) to increase the sugar content of crops.

Next, the outline of the electrolyzed water cultivation test results of the crops conducted by the inventors will be described below. In a 35 m ² greenhouse, a cultivar: Momotaro 93T tomato was cultivated in the control plot (tap water) and the electrolytically reduced water plot (A and B), and a cultivation comparison test was conducted by ground cultivation. Tap water (ORP = 432 to 487 mV) is irrigated daily in the electrolytic reduction water zone and the control zone, and electrolytic reduced water (A and B) is once a week in the electrolytic reduction water zone, April 13, 2005- Table 1 shows the results of foliar spraying 15 times during the period of July 20th. As a result, the quantity, total fruit weight, and average fruit weight are higher in the electrolytic reduction water section than in the control section. Specifically, the electrolytic reduction water group had a result that the quantity was increased by 20 to 29%, the total fruit weight was increased by 33 to 41%, and the average fruit weight was increased by about 10%. Further, the average sugar content is 0.5 to 0.8 degrees higher in the electrolytically reduced water section than in the control section, and the electrolytic reduced water B having a shorter standing time and lower ORP has a higher sugar content than the electrolytically reduced water A. From the above results, it was confirmed that when tomatoes were cultivated with electrolytically reduced water, the yield increased and sweeter and delicious tomatoes were cultivated.

Table 2 shows the results of a cultivation comparison test by planter cultivation in a 35 m ² greenhouse with varieties: Momotaro 93T tomatoes in the control zone (tap water) and the electrolytic reduction water zone (A and B). Tap water (ORP = 432 to 487 mV) is irrigated daily in the electrolytic reduction water zone and the control zone, and electrolytic reduced water (A and B) is once a week in the electrolytic reduction water zone, June 1, 2005- During the period of July 27, foliar spraying was performed nine times. As a result, the quantity is not significant in the control group and the electrolytic reduction water group, but the electrolytic reduction water B group is 23% more than the control group, and the average fruit weight is 14% in the electrolytic reduction water than in the control group. -17% heavier results were obtained. Further, the average sugar content is 0.5 to 1.0 degree higher in the electrolytic reduction water group than in the control group, and the electrolytic reduction water B having a shorter standing time and lower ORP has a sugar content of 0 than the electrolytic reduction water A. .5 degree higher result was obtained. From the above results, it was confirmed that when tomatoes were cultivated with electrolytically reduced water, large tomatoes were cultivated and increased in yield, and sweet and delicious tomatoes were cultivated.

In a 35 m ² greenhouse, cultivar: Kuroyo eggplant was subjected to a comparative cultivation test in the control zone (tap water) and electrolytic reduction water zone (A and B). Tap water (ORP = 432 to 487 mV) is irrigated daily in the electrolytic reduction water zone and the control zone, and electrolytic reduced water (A and B) is once a week in the electrolytic reduction water zone, April 13, 2005- Table 3 shows the results of foliar spraying 14 times during the July 13 period. As a result, the quantity is not significant in the control zone and the electrolytic reduction water zone, but the average sugar content is 0.8 to 1.6 degrees higher in the electrolytic reduction water zone than in the control zone, and the leaving time is short, The result was that the electroreduced water B having a lower ORP had a sugar content higher by 0.8 degrees than the electroreduced water A. From the above results, it was confirmed that eggplants with high sugar content were cultivated when there was no change in yield when cultivated by electrolytic reduction.

  A sweet corn of three varieties, Peter Corn, Queen Bee, and Sunny Taste, was subjected to a cultivation comparison test by outdoor cultivation in the control zone (tap water) and the electrolytic reduction water zone. Tap water (ORP = 432 to 487 mV) is irrigated daily in the electrolytic reduction water zone and the control zone, and electrolytic reduced water (ORP = -150 to -173 mV) is fed into the electrolytic reduction water zone once a week for a total of 9 leaves. Table 4 shows the results of surface spraying. As a result, the sugar content varies depending on the variety, but sweet corn is cultivated in the electrolytically reduced water zone 1.0 to 2.0 degrees higher than the control zone, and the harvesting season is more in the electrolytically reduced water zone than the control zone. It was confirmed that it was 7-10 days earlier.

  Five types of radish, cucumber cucumber, cherry tomatoes, green soybeans, and cucumbers were subjected to a cultivation comparison test by outdoor cultivation in the control plot (tap water) and the electrolytic reduction water plot. Tap water (ORP = 432 to 487 mV) is irrigated daily in the electrolytic reduction water zone and the control zone, and electrolytic reduced water (ORP = -150 to -173 mV) is fed into the electrolytic reduction water zone once a week for a total of 6 leaves. Table 5 shows the results of surface spraying. As a result, the sugar content of the electrolytically reduced water group is 1.0 degree for radish, 2 degrees for cucumber, 1.5 degrees for cherry tomatoes, and 2.0 degrees for green soybeans, but the cucumber is electrolyzed with the control group. There was no significant difference in the reduced water area.

  In the inventor's home garden, a cultivar comparison test by planter cultivation was conducted in the control plot (tap water) and the electroreduction water plot for the cucumber of the cultivar: Seiroku Shigenari. Two cucumber seedlings are planted in a planter, tap water (ORP = 432 to 487 mV) is irrigated every day to the planter, and electrolytically reduced water (ORP = -150 to -173 mV) is sprayed on the surface of one cucumber. Table 6 shows the results of cultivation in which fine mist is sprayed at intervals of 3 to 7 days and the other is not sprayed. As a result, cucumber sprayed with electrolytically reduced water yielded 2.1 times more quantity than the non-sprayed, 2.7 times the total fruit weight, and 26% average fruit weight. The cucumber sprinkled with reduced water had a higher fruiting rate, fewer irregular and bent abnormal fruits, and the harvest period was 24 days longer. However, there was no significant difference in sugar content between spraying with electroreduced water and non-spraying.

  Based on the electrolysis water cultivation test results of the agricultural products described above, the theory of the action and effect of electrolytic reduction water on the crops will be described below. The ORP (oxidation-reduction potential) of electrolytically reduced water is water having a potential of −100 to −200 mV and has a reducing power. Leaves damaged by ultraviolet rays from sunlight are damaged by oxidative stress, etc. When the water with this reducing power touches the leaf surface of the crop, electrolytic reduced water reduces the leaves of the oxidative stress. It is assumed that In other words, by reducing the oxidative stress of oxidized and damaged crops and leaves of plants, photosynthesis also becomes active and effectively acts on the growth of crops and plants, improving growth, increasing sugar content, improving taste, increasing yield, It is presumed that it has an effect on the improvement of the harvest season.
