が不要であるという利点を有する。(Prior Art) In hydroponics of plants, it is particularly important to solve the two problems of how to supply oxygen to roots and how to constantly supply nutrients with a concentration suitable for cultivation to roots. Is. Then, various methods for solving this problem have been created and proposed. One of such methods,
There is a floating root hydroponics method according to the present invention. With this method,
Since the root part can absorb oxygen from the air, it is easy to supply oxygen, and compared with other methods of immersing the root part in the nutrient solution,
It has an advantage that operations such as bubbling of a nutrient solution for supplying oxygen to the root are unnecessary.

開昭61−54348号）。As a device for the seed-root type hydroponic culture, for example, the device shown in FIG. 2 is known. In this method, a supporting portion 2 made of, for example, a styrofoam plate, which supports the root portion 30 of the plant 20, is floated in the liquid storing portion 1 containing the nutrient solution, and the nutrient solution is applied to the upper horizontal surface of the supporting portion 2 by a capillary force such as a nonwoven fabric. The liquid absorbing member 3 to be sucked up is placed so as to be partially immersed in the nutrient solution, and the liquid passing sheet 4 for preventing roots from entering the nutrient solution is placed on the liquid absorbing member 3. This liquid passing sheet 4
The root part 30 is supported on the upper part of the root so that the root can grow. Also, assuming that it has a configuration similar to this,
In FIG. 2, it is known that a solid medium (not shown) in which plants are planted is placed on the liquid passing sheet 4 and the nutrient solution is supplied to this solid medium by capillary force. (Actual No. 61-54348).
（発明が解決しようとする問題点） しかしながら、空中にある根部に毛管力により養液を

り、粗植を余儀なくされる。(Problems to be Solved by the Invention) However, these devices that adopt a method of supplying a nutrient solution to the root part in the air by a capillary force have the following drawbacks. That is, the plant needs different nutrients depending on its growth period and selectively absorbs the components in the nutrient solution. For this reason, in the central part of the solid medium or the liquid-passing sheet, the components not absorbed by the roots, such as iron, magnesium, and calcium, are accumulated, and the nutrient solution at the part where the roots actually contact, A phenomenon occurs in which the composition and concentration are changed, which is not suitable for plant growth. As a result, the normal growth of the root part in the central part is inhibited, while the root grows in the peripheral part equal to the nutrient solution composition in the liquid storage part 1, and as shown in FIG. It grows unevenly around the liquid sheet.
Therefore, in order to make the roots necessary for the growth of the plants grow, the control area of the support part per plant becomes large, and the rough planting is unavoidable.
また、植物根部への養液の供給が毛管力のみで行われ
るため、植物の種類や栽培される地域によっては植物体
が吸収する養水分の量に不足をきたす場合があり、植物
の生育段階に応じた生育の調節を行うことができない。In addition, since the nutrient solution is supplied only to the root of the plant by capillary force, the amount of nutrient water absorbed by the plant may be insufficient depending on the type of plant and the area where it is cultivated. It is impossible to control the growth according to.
（問題点を解決するための手段） 本発明者らは、以上のような欠点を解消し、正常な根

生育を調節しうる養液栽培装置を提供することを目的と
して検討した結果、本発明を完成した。(Means for Solving Problems) The present inventors have solved the above-mentioned drawbacks, promoted normal root growth, increased planting density, and were able to regulate plant growth. As a result of the study for the purpose of providing a liquid culture device, the present invention has been completed.
すなわち本発明は、養液の貯液部と、植物の根部を支

を供給する養液供給管を備え、養液供給管を通液シート
上に配置し、養液供給を植物の生長に応じて調節する傾
斜型浮根式養液栽培装置である。That is, the present invention is a storage part of the nutrient solution, a support part having an inclined surface for supporting the root part of the plant, a liquid absorbing member placed on the support part to suck up the nutrient solution and supply it to the plant, Equipped with a nutrient solution feed pipe that prevents nutrients from invading into the nutrient solution and a nutrient solution supply pipe that supplies the nutrient solution to the roots. It is an inclined type rooted-type hydroponics device that is adjusted according to the type.
（作用） 本発明において使用される支持部は、植物の根部を支
持する作用のほかに、その上面が傾斜面になっている結
果、次の作用を有する。(Action) In addition to the action of supporting the root of a plant, the support used in the present invention has the following action as a result of its upper surface being an inclined surface.
すなわち、根部はこの傾斜面上に吸液部材、通液シー
トを重ね、この通液シート上面の植物根部の生育空間で
生長する。この通液シート上に直接供給するようにした
養液供給管から、植物の養水分吸収により減少した分だ

面の通液シート上面に蓄積されつつある、植物の選択吸
収によりもたらされた余剰成分等を洗浄排除し、かかる
部位の養液組成を簡易迅速に当初の好ましい組成にもど
すことができる。In other words, the root part grows in the growth space of the plant root part on the upper surface of the liquid-permeable sheet by stacking the liquid-absorbent member and the liquid-permeable sheet on the inclined surface. From the nutrient solution supply pipe that is directly supplied onto the liquid passage sheet, new nutrient solution is additionally supplied by the amount reduced by absorption of nutrient water of the plant, and the nutrient solution in the reservoir can be circulated and supplied. By doing so, excess components and the like that are being accumulated on the upper surface of the liquid passing sheet on the inclined surface of the support portion 2 and brought about by the selective absorption of plants are washed away, and the nutrient solution composition of such a portion can be simply and quickly set to the initial value. It can be returned to the preferred composition.
その結果余剰成分の蓄積による根部の生育阻害は生ぜ
ず、根を通液シート上面に隅なく成長させることができ
るばかりでなく、根部への養液供給を循環の液量および
その回数等で調節することにより、人為的に植物の生育
をコントロールすることができる。As a result, the growth of roots is not inhibited by the accumulation of excess components, and not only can roots be grown on the upper surface of the liquid-flowing sheet without any corners, but the nutrient solution supply to the roots can be adjusted by the amount of circulation liquid and the number of times. By doing so, it is possible to artificially control the growth of the plant.
