PROBLEM TO BE SOLVED: To provide cultivation environment having good drainage, in water culture using a culture medium for nutriculture in which a culture medium material, such as a wood chip, a coconut shell, and rock wool, has a slab shape.SOLUTION: A placing table 1 is composed of a base 10 made of expanded polystyrene having a placing surface 11 on which a culture medium 2 is placed as an upper surface. The placing surface 11 is composed of a roof-shaped inclined plane which is inclined downward from a central part of the upper surface of the base 10 toward each of the front and the rear. In the base 10, a plurality of nutrient liquid discharge grooves 12 are formed at intervals of 100 mm in a longitudinal direction so as to depress from the placing surface 11. Each of nutrient liquid discharge grooves 12 is formed so that each of groove bottoms 12a is inclined downward from the rear end side to the front side of the base 10. The rear end of each nutrient liquid discharge grooves 12 is covered with an inclined surface 12b connecting a rear end corner part 10a of the base 10 and the groove bottom 12a. In the front end of each nutrient liquid discharge groove 12, a front surface groove 13 which is largely inclined downward so as to depress from the front surface side of the base 10.COPYRIGHT: (C)2014,JPO&INPIT【課題】木質チップ、椰子殻、ロックウールなどの培地素材をスラブ状にした養液栽培用培地を用いた水耕栽培において、水はけ良好な栽培環境を提供する。【解決手段】載置台1は、培地2を載置する載置面11を上面とする発泡スチロール製の基台10からなる。載置面11は、基台10の上面の中央部から前方及び後方のそれぞれに向かって下り傾斜となる屋根状の傾斜面で構成される。基台10には、載置面11から凹入する様に、長手方向100mm間隔で、多数の養液養液排出溝12,12,…が形成されている。各養液排出溝12は、それぞれの溝底12aが、基台10の後端側から前端側に向かって下り傾斜となる様に形成され、後端は基台10の後端角部10aと溝底12aとをつなぐ傾斜面12bで塞がれ、前端には、より勾配の大きい下り傾斜の前面溝13が基台10の前面側から凹入する様に連続して形成されている。【選択図】 図1
