PROBLEM TO BE SOLVED: To provide a plant cultivation system by which plants efficiently and stably absorb a sufficient amount of gas such as carbon dioxide or hydrogen from the roots of the plants without causing oxygen deficiency in their roots leading to root rot and the like so as to remarkably and continuously promote growth of the plant over a long period of time.SOLUTION: The plant cultivation system includes: an imperforate hydrophilic film for cultivating the plants thereon gas-dissolved water obtained by dissolving at least one kind of gas which promotes the growth of the plants, and put in a position so as to come in contact with the undersurface of the imperforate hydrophilic film and a gas-dissolved water-holding means for holding the gas-dissolving water under the imperforate hydrophilic film.COPYRIGHT: (C)2012,JPO&INPIT【課題】根ぐされなどの原因となる根の酸素欠乏状態を招くことなく、効率的且つ安定的に十分な量の二酸化炭素や水素などの気体を植物の根から吸収させることができ、それにより長期間に亘り持続的に植物の生長を著しく促進させることを可能にする植物栽培用システムを提供する。【解決手段】 植物をその上で栽培するための無孔性親水性フィルム;植物の生育を促進する少なくとも1種の気体を水に溶解させて得られる気体溶解水であって、該無孔性親水性フィルムの下面に接触するように配置された気体溶解水;および該気体溶解水を、該無孔性親水性フィルムの下に保持するための気体溶解水保持手段を含むことを特徴とする、植物栽培用システム。【選択図】図1
