である。(Problems to be Solved by the Invention) However, in the above conventional means, when processed air with an ozone concentration of 1100 pp, for example, is diffused into the culture solution in the cultivation tank, ozone gas is dissolved in the culture solution. Its concentration is 0. Since the O2 concentration was less than 5 ppm, not only was it impossible to sufficiently sterilize the culture solution, but there were also fatal problems such as the growth of pathogenic bacteria and algae in the cultivation tank.

。First, open the valve 14 and operate the pump 13,
Cucumbers are cultivated for 8 days by supplying the culture medium 12 in the culture solution tank 11 into the culture tank 7. In this case, the valve 10.17 is closed and the culture solution 12 is fed into the culture tank 7. 1
1 and cultivation tank 7. Cultivation tank 1 for the last 8 days
The number of microorganisms in the culture solution 12 of No. 1 is shown by the dashed-dotted line in FIG.
そして、８日目からオゾン水２３を供給して殺菌を行う

孔１６を介して排出用配管１５から外部へ流出される。Then, from the eighth day, ozonated water 23 is supplied to perform sterilization. In this case, first close the valves 14 and 19 while opening the valves 10 and 11 to start the ozonated water generator 1, and then the ozonated water 23 flows from the ozonated water generator 1 into the cultivation tank 7. This ozonated water 23 is directly supplied and flows out from the discharge pipe 15 through the discharge hole 16 to the outside.
かかるオゾン水２３の供給を１時間行った後に、オゾン

水口のもので、点線が排水口のものである。In this way, the number of microorganisms in the culture solution 12 after supplying the ozonated water 23 for one hour was investigated near the water supply port and the drain port of the cultivation tank. The test results are shown in FIG. 2, and the solid line The dotted line is for the water inlet and the dotted line is for the drain.

ある。According to this, no microorganisms were detected near the water inlet on the first day, and 4°l x IO'cfu/s near the outlet.
+1 microorganism count was detected, but it decreased as the number of ozonated water supply days passed, and after 10 days it was 3.8X102c.
An excellent bactericidal effect of 1.5 fu/ml was obtained.
また、オゾン水２３の直接供給による植物体への影響を
調べたところ、根及び株の上位葉への影響はなかったが
、給水口付近の株の下位葉でオキシダントによる症状が
認められた。Furthermore, when we investigated the effects of direct supply of ozonated water 23 on the plant body, there was no effect on the roots or upper leaves of the plant, but symptoms caused by the oxidant were observed on the lower leaves of the plant near the water inlet.
而して、栽培槽７に定期的にオゾン水２３を直接供給し

抑制できることが確認できたのである。Therefore, even if the ozonated water 23 is directly supplied to the cultivation tank 7 on a regular basis, the ozonated water 23 in the cultivation tank 7 can be reduced by, for example, branching the ozone 23 at several points as in the embodiment. It was confirmed that if the concentration gradient is set to a small value, there is almost no effect on the roots of the plants, and the density of microorganisms in the cultivation tank 7 can be suppressed to an extremely low level.
尚、栽培槽７内への藻類の発生もオゾン水処理期間中に
於いて全く認められなかった。Incidentally, no algae were observed to grow in the cultivation tank 7 during the ozone water treatment period.

る。That is, since the ozonated water 23 with a concentration of 0.5 to 1 ppm is used, even if this ozonated water 23 is directly supplied to the cucumber seedlings 22, it will not damage the roots of the cucumber seedlings 22, and will not cause any damage to the roots, such as Fusarium fungi, etc. It has been recognized that it has an excellent sterilizing effect in that it can sterilize tomato blight bacteria, etc., and can also successfully sterilize pathogenic bacteria that occur on the surface of cucumber roots, and can also sterilize the cultivation tank 7 itself. This has resulted in various benefits, including the ability to contribute to suppressing the growth of algae.
尚、この種養液栽培に於いては、少なくとも前記フザリ
ウム園やトマト膏枯病菌の殺菌が行えれば十分であり、
これにより植物体に支障をきたすことなく良好な栽培が
行えるのである。In addition, in this kind of hydroponic cultivation, it is sufficient to at least sterilize the Fusarium garden and tomato blight bacteria,
This allows for good cultivation without causing any problems to the plants.

７内の沈澱物を除去するような煩雑な作業も要しないと
いう実用的な利点も有することとなる。In addition, since the ozonated water 23 supplied into the cultivation tank 7 is made to flow out, even if the components in the culture solution 12 and the ozonated water 2
Even if impurities are generated due to a chemical reaction between the cultivation tank 7 and the cultivation tank 7, they are discharged to the outside without being precipitated in the cultivation tank 7. Therefore, a good sterilization condition can always be maintained in the cultivation tank 7, and as a result, a separate cultivation tank 7 It also has the practical advantage of not requiring complicated work such as removing precipitates inside.
尚、上記実施例に於いては、培養液１２とオゾン水２３

両者を同時に供給しても、オゾン水２３の殺菌効果は失
われるものではない。In the above embodiment, the culture solution 12 and ozone water 23
and are alternately supplied to the cultivation tank 7,
Even if both are supplied at the same time, the bactericidal effect of ozonated water 23 is not lost.
さらに、オゾン水発生装置１の具体的な構成も問うもの
ではなく、要は濃度０．５〜１． Ｏｐｐｍのオゾン水
２３を生成可能なものであればよい。Furthermore, the specific configuration of the ozonated water generator 1 is not a problem, but the concentration is between 0.5 and 1. Any material that can generate Oppm ozonated water 23 may be used.
また、適用植物も上記実施例のキュウリに限定されず、
種々の植物の養液栽培に対して幅広く使用可能なことは
言う迄もない。In addition, the applicable plants are not limited to the cucumbers in the above examples,
Needless to say, it can be widely used for hydroponic cultivation of various plants.
その他、配管等の各部の構成も本発明の意図する範囲内
に於いて任意に設計変更自在である。In addition, the configuration of each part such as piping can be freely changed in design within the intended scope of the present invention.

効果か得られたのである。(Effects of the Invention) As described above, the present invention improves the concentration of ozonated water to 0.5 to 1.0, which does not damage the roots of plants. Oppm is set and the ozonated water is directly supplied to the cultivation tank.
Compared to conventional methods that sterilize the culture solution at a low concentration of about O,OSρpff1, it has a much superior sterilizing effect, and can also sterilize the cultivation tank and suppress the growth of algae. A particularly remarkable effect was obtained in that it also sterilized the roots of the plant.

う特有の効果を奏する。In addition, if the structure is configured to allow the ozonated water supplied to the cultivation tank to flow out, even if a chemical reaction occurs between the culture medium and the ozonated water in the cultivation tank, impurities will not be precipitated in the cultivation tank and will be discharged from the outside. Therefore, it is possible to prevent the occurrence of turbidity in the cultivation tank, and there is a unique effect that there is no need to perform complicated operations such as removing precipitates, which were required in the past.
