PROBLEM TO BE SOLVED: To provide a plant cultivation device easily controlling environmental conditions of temperature and moisture of a culture medium, especially, a plant root zone environment, without complicated and expensive facilities, and to provide an elevated cultivation device supporting the plant cultivation device to place in an appropriate height from the ground without complicated and expensive facilities.SOLUTION: This plant cultivation device is provided with a tubular culture medium which has a culture medium tube on an external surface or an internal surface of a support tube and a hollow path in which both ends are communicated in the inside and extend, and horizontally or inclinedly supports the tubular culture medium. Furthermore, the device includes a culture medium watering means which passes through the hollow path for watering the culture medium tube, and/or a culture medium heating cooling means which faces or passes through the hollow path for heating and cooling the culture medium tube. The support tube has many through holes on a tube wall when having the culture medium tube on the external surface.COPYRIGHT: (C)2010,JPO&INPIT【課題】複雑で高価な設備なしに、培地の温度や水分の環境条件、特に、植物の根域環境を容易に制御することができる植物栽培装置を提供する。更に、本発明は、複雑で高価な設備なしに、上記植物栽培装置を地面から適宜高さに位置するように支持した高設栽培装置を提供する。【解決手段】本発明によれば、支持管の外側表面又は内側表面に培地管体を有せしめて、内側に両端を連通して延びる中空路を有する管状培地とし、この管状培地を水平に又は傾斜させて支持してなり、上記培地管体に灌水するために上記中空路を挿通する培地灌水手段を備え、及び/又は上記培地管体を加熱冷却するために上記中空路を臨んで若しくは上記中空路を挿通する培地加熱冷却手段を備えていると共に、上記支持管が外側表面に培地管体を有するときは、支持管が管壁に多数の貫通孔を有する植物栽培装置が提供される。【選択図】図3
