PROBLEM TO BE SOLVED: To solve the problem that the conventional plant culture apparatus, particularly a horticulture, is in a state in which a soil layer 13 is always wet caused by a condition in which roots and stems of plants are submerged under water, or by scattering of water drops, therefore the condition causes for root rot by generating the condition in which the degree of water rot is high, the soil layer is easily oxidized and has bad aeration, so the roots can not breathe, therefore the culture apparatus is limited to plants strong to water or preferring water, and is a culture apparatus for limited plants.SOLUTION: Various species of plants are brought to be able to grow by improving the growth environment of the plants in a soil layer 13 by installing a water layer 4, an air/water layer 7, an air layer 9 and the soil layer 13, vaporizing elements required of the plants from a liquid (water) to a water-containing air (moist air) through the function of each layer, particularly the air layer 9, guiding the air from the inside of the air layer 9 having generated the state of pressure elevation to a vent plate 11 placed on the bottom surface of the soil layer 13, supplying the elements required of the plants by permeation, vaporizing and scattering them into the soil layer 13 and transpiring on the surface of the soil layer 13.COPYRIGHT: (C)2013,JPO&INPIT【課題】 従来の植物の栽培装置、特に水耕栽培は、植物の根、茎が水に浸かった状態または水滴が飛散することによって、土壌層13は常に濡れた状態であった。そのため水の腐敗率が高く、酸化しやすく、通気性が悪く、根が呼吸できない状態を生じ,根腐れの原因となっていた。そのため水に強いもしくは好む植物に限られ、限度のある植物の栽培装置であった。【解決手段】 水層4・気水層7・空気層9・土壌層13を設け各層の機能により、特に空気層9によって、植物の必要な要素を液体(水)から水を含んだ空気(湿り空気)へと気化させその気体を断続した圧力上昇状態を生じた空気層9内から土壌層13底面に設けられた通気口板11に誘導され、土壌層13内へ通気・蒸発・拡散しながら植物の必要要素を供給し、土壌層13表面にて蒸発散を行うことにより土壌層13内の植物の育成環境を向上させることにより多種多様な植物の育成を可能とした。【選択図】図1
