摘要：
PROBLEM TO BE SOLVED: To provide a water tank for capillary hydroponic cultivation by which fresh cultivation liquid can be easily supplied to crops, and a supply amount of cultivation liquid to crops can be easily adjusted.SOLUTION: A water tank for capillary hydroponic cultivation according to an aspect of the present invention is a water tank that stores cultivation liquid and is formed in a gutter shape, and comprises a top part having a belt-like opening, and a bottom part which is positioned below the top part and has a smaller internal average width than the top part. It is desirable that at least one sidewall of a pair of sidewalls of the top part has through-holes. Further, it is desirable that the tank includes a tapered part that widens upward between the top part and the bottom part. Further, it is desirable that a cross-sectional shape is laterally symmetrical with a central vertical line as a reference, an internal width of the top part and an internal width of the bottom part are constant. Further, it is desirable that a water storage amount in the bottom part is 20 vol.% or more and 100 vol.% or less of a water absorption amount per day of mature seedlings of crops to which cultivation liquid is supplied. Further, it is desirable that a main constituent material of the water tank for capillary hydroponic cultivation is foaming thermoplastic resin.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】新鮮な栽培液を作物に供給し易く、かつ作物への栽培液の供給量を調節し易い毛管水耕栽培用水槽を提供する。【解決手段】本発明の一態様に係る毛管水耕栽培用水槽は、栽培液を貯留する水槽であって、樋状に形成されており、帯状の開口を有する上部と、この上部の下方に位置し、上部より内部平均幅が小さい下部とを備える。上記上部の一対の側壁の少なくとも一方の側壁に貫通口を有するとよい。また、上記上部及び下部間に上方に拡幅するテーパ部を備えるとよい。また、横断面形状が中心鉛直線を基準として左右対称であり、上記上部の内部幅及び上記下部の内部幅が一定であるとよい。また、上記下部の貯水量としては、栽培液を供給する作物の成苗の1日当たりの吸水量の20体積%以上100体積%以下が好ましい。また、当該毛管水耕栽培用水槽の主構成材料としては、発泡熱可塑性樹脂が好ましい。【選択図】図2
