である。(Function) Water tank for adjusting the culture solution (10 liters is the pipe for draining the culture solution (9)
The culture solution supplied to the re-cultivation tank is reduced in concentration due to the absorption of nutrients by the crops, the pH fluctuates due to the imbalance of absorption factors, and the oxalic acid produced by the plants and the fungi grown in the cultivation tank are mixed together. The liquid contained in the liquid is returned from the return pipe (15) as a return liquid (14) to the culture liquid adjustment water tank (10). This culture solution (7) is a mixture of such culture solutions.

れる。This water supply surplus liquid return pipe (4) has enough water pressure to spray the culture solution in the air, take in air, and dive into the culture solution, and is branched from there and attached. The culture solution is originally flowing at a considerable speed inside the culture solution air mixer (5). In this culture solution air mixer, the tube is made thinner to increase the flow rate, and immediately after that, the tube is made thicker to create negative pressure, and the ozone and ion-activated oxygen injection tube (2) is placed at that point at the outlet. (3)
Attach the culture solution (7) and the ion- and ozone-containing gas to mix vigorously and diffuse them into the culture solution adjustment water tank (10) in the form of fine bubbles (6). This is done in a very short time. Therefore, the culture solution (7) is mixed with ions and ozone-containing gas many times in this culture solution adjustment water! (10), the culture solution is activated and reacts, and the culture solution is disinfected and activated. It is supplied to the cultivation tank through the outflow pipe (9).

安定であるからである。農家経営にとって、栽培が不安
定と言うことは導入不可能を意味する。(Example) The number of farms in Japan that mainly incorporate hydroponic cultivation of spinach into their management is within a few. The reason is that cultivation is unstable. For farm management, unstable cultivation means that introduction is impossible.

生産不安定解消に有効なことを確認した。The method was carried out as a basic test at a small-scale facility while examining its effects in detail, and the results were found. Ozone + ions were generated using high-voltage plasma discharge using a newly developed electrode based on a new material design based on agricultural improvements. Using a newly developed device that can adjust the concentration and supply active oxygen according to the purpose, it was confirmed that it is effective in resolving production instability in spinach hydroponic cultivation.

である。(Effects of the invention) In basic tests, it was found that it was possible to hydroponically cultivate spinach five times in a row, and it was also effective in reducing the water-soluble oxalic acid content in the spinach body. However, there is a gap between basic tests and practical tests.For example, if the cultivation scale is doubled, it does not mean that everything needs to be doubled. The culture solution is aged by plug flow (1
The culture solution is not pushed out, but moves downward as it mixes, so if the length of the culture tank doubles, it will take more than twice as long to renew.
In some cases, results from basic tests may not be seen on a practical cultivation scale. It is necessary to have an idea on a practical scale.

オン活性化酸素の効果が見られることが確認できた。We investigated the practical application of this ozone and ion-activated oxygen generator even under conditions that are restricted from a farm-scale management standpoint. As a result, we were able to confirm that even in large-scale cultivation, spinach grew well without any problems, and that the effects of ozone and ion-activated oxygen were evident.
このことは、農業界に於ける特筆すべき成果であると思
