れる直流電源（図示せず）より直流電圧を印加し、養液
中に電流を流して水を電気分解していた。Conventional technology A conventional hydroponic cultivation system that electrolyzes the water in the nutrient solution and supplies the generated oxygen to the nutrient solution to ensure dissolved oxygen in the nutrient solution is shown in Figure 2. Nutrient tank 1 as shown
An anode 2 and an anode 3 made of corrosion-resistant electrodes such as carbon electrodes are placed inside, and a DC voltage is applied to these electrodes 2 and 3 from a DC power source (not shown) made of a solar cell or the like. Water was electrolyzed by passing an electric current through the nutrient solution.
発明が解決しようとする問題点
ところが養液中には肥料成分として多量のイオンを含ん
でおり、これらのうち陽・イオンである金属イオンのカ
リウムイオン、カルシウムイオン。The problem that the invention aims to solve However, the nutrient solution contains a large amount of ions as fertilizer components, and among these, potassium ions and calcium ions are metal ions that are cations and ions.
マグネ／ラムイオン等は負極３に引き寄せられて遂には
接触し、その負極３から電子を受けて金属原子となり、
負極３表面へと析出していた。Magne/Lum ions, etc. are attracted to the negative electrode 3 and finally come into contact, receive electrons from the negative electrode 3 and become metal atoms,
It was deposited on the surface of the negative electrode 3.
そのため養液中の金属イオン特にカルシウムイオン、マ
グネシウムイオン、が減少し、極端な場合はそれら金属
イオンの欠乏症状が栽培している植物に発生するという
問題があった。As a result, metal ions, particularly calcium ions and magnesium ions, in the nutrient solution decrease, and in extreme cases, there is a problem that symptoms of deficiency of these metal ions occur in the cultivated plants.
また逆に陰イオンは硝酸イオンと硫酸イオンのように水
酸イオンよシイオン化傾向が高いイオンであるため、陽
極２に引かれて陽極２に近づいても陽極２に電子を与え
て分解することはない。つまり、陽極２では常に水酸イ
オンが分解され水と酸素となっていた。Conversely, anions, such as nitrate and sulfate ions, have a higher tendency to ionize than hydroxide ions, so even if they are attracted to the anode 2 and approach the anode 2, they will give electrons to the anode 2 and be decomposed. There isn't. In other words, at the anode 2, hydroxide ions were always decomposed into water and oxygen.
従って、養液中の水素イオン濃度が徐々に上昇し、遂に
は養液の水素イオン濃度が２〜３にまでなシ、植物の根
へ悪影響を及ぼすという問題もあった。Therefore, the hydrogen ion concentration in the nutrient solution gradually increases until the hydrogen ion concentration in the nutrient solution reaches 2 to 3, which has a negative effect on the roots of the plants.
本発明は上記従来の水の電気分解を養液へのり素供給に
利用する方式の水耕栽培装置の″）照点を改善し、よシ
使用性の高い水耕栽培装置を提供することを目的とする
。The present invention aims to improve the illumination point of the conventional hydroponic cultivation apparatus using electrolysis of water to supply glue to the nutrient solution, and to provide a hydroponic cultivation apparatus with high usability. purpose.
問題点を解決するための手段
上記従来の問題を解決すべく、本発明による水耕栽培装
置は、養液を貯留し且つ植物の根を成長させるだめの養
液槽内に一対の電極を配し、そのうち陰極は少なくとも
その壁の一面をイオン選択透過膜で構成した筐体内に配
しである。Means for Solving the Problems In order to solve the above-mentioned conventional problems, the hydroponic cultivation apparatus according to the present invention includes a pair of electrodes arranged in a nutrient solution tank in which a nutrient solution is stored and roots of plants are grown. However, the cathode is disposed within a housing having at least one wall made of an ion selectively permeable membrane.
作 用
上記養液槽内に養液を入れ陽極、陰極間に直流電圧を印
加するとこれら電極間の養液中を電流が流れ電気分解が
発生する。Function: When a nutrient solution is placed in the nutrient solution tank and a DC voltage is applied between the anode and cathode, a current flows through the nutrient solution between these electrodes and electrolysis occurs.
養液中の水酸イオンは陽極へと引かれ、この陽極表面へ
電子を与えて分解され水と酸素になる。The hydroxide ions in the nutrient solution are attracted to the anode, give electrons to the anode surface, and are decomposed into water and oxygen.
また養液中のカルシウムイオンやマグネシウムイオン等
の金属イオンは陰極側へ引きつけられるが、筐体に設け
られたイオン選択透過膜に阻まれ、陰極にまで至ること
はない。陰極には筐体内の水中の水素イオンが集まり、
陰極表面より電子が供給されて水素原子さらに水素分子
となり、水素ガスとなる。Further, metal ions such as calcium ions and magnesium ions in the nutrient solution are attracted to the cathode side, but are blocked by the ion selective permeation membrane provided in the housing and do not reach the cathode. Hydrogen ions in the water inside the housing gather at the cathode,
Electrons are supplied from the cathode surface to form hydrogen atoms and further hydrogen molecules, resulting in hydrogen gas.
従って、水素イオンよシイオン化傾向の低いカルシウム
イオンやマグネシウムイオンが陰極表面に析出すること
はない。また陽極で分解し水と酸素になる水酸イオンと
同当量の水素イオンが陰極で水素ガスとなるため、常に
養液中の水素イオンと水酸イオンのバランスはくずれる
ことはなく、水素イオン濃度が異常に変化していくこと
はない。Therefore, calcium ions and magnesium ions, which have a lower tendency to ionize than hydrogen ions, do not precipitate on the cathode surface. In addition, the same amount of hydrogen ions as the hydroxide ions decomposed at the anode to become water and oxygen become hydrogen gas at the cathode, so the balance between hydrogen ions and hydroxide ions in the nutrient solution is always maintained, and the hydrogen ion concentration does not change abnormally.

はない。In FIG. 1, numeral 11 is a nutrient solution tank made of synthetic resin that is highly resistant to salt water, in which the nutrient solution is stored and the roots of plants are grown in it. In this nutrient solution tank 11, an anode 12 and a cathode 13 made of carbon are arranged. The anode 12 is formed in a net shape, and the cathode 13 is a bottomed cylinder made of synthetic resin, with a top surface l (a housing 15 having a partition wall with an ion selective permeation membrane 14).
It is set inside. Even if a DC voltage is applied to the positive and negative electrodes 12 and 13), the metal ions in the nutrient solution will pass through the ion selectively permeable membrane 1.
4, it is blocked here and cannot reach cathode 13,
Therefore, it remains as an ion. Hydrogen ions in the housing 15 gather at the cathode 13, receive electrons from the cathode 13, and become hydrogen gas. Further, on the anode 12 side, hydroxide ions in the nutrient solution are attracted to the anode 12, giving electrons to the anode 12 and decomposing it into water and oxygen, as in conventional hydroponic cultivation equipment. Since other nitrate ions, sulfate ions, etc. present as fertilizer components in the nutrient solution have a greater tendency to form ions than hydroxide ions, they are not decomposed at the anode 12 while hydroxide ions are present.
従って、陽極１２側では電解により常に必要な酸素を発

た金属イオンの析出は発生しない。Therefore, while the necessary oxygen is always generated by electrolysis on the anode 12 side, metal ion precipitation that occurs in conventional hydroponic cultivation devices does not occur on the cathode 13.
そのため養液中の水素イオン濃度が異常に変動すること
もない。Therefore, the hydrogen ion concentration in the nutrient solution does not fluctuate abnormally.

効果を有する。Effects of the Invention As described above, the hydroponic cultivation apparatus according to the present invention has a fertilizer component in the cathode part, and an ionized Calcium ions, magnesium ions, etc., which have a low tendency to precipitate, disrupt the ion balance and do not have a negative effect on plants, and metal ions precipitated at the cathode cause abnormal fluctuations in hydrogen ion concentration, which has a negative impact on plants. It has the useful effect of being very easy to use and does not cause any adverse effects.
