Summary:PROBLEM TO BE SOLVED: To provide plant cultivation apparatus and plant cultivation methods that can cultivate plants with suitable illuminance for a cultivation period, has high repeatability of yield, and also can drastically reduce power consumption of the lighting device for plant cultivation.SOLUTION: A six-sided constituting member that constitutes the six surfaces surrounding a cultivating space region, while having a reflecting surface and facing the reflecting surface to the cultivating space region side, is constituted by a light reflective layer 26 and reflective plates 27, 29. A lighting device controller 35 controls the beam irradiated from the light source of a plant cultivating lighting device 25 so that the illuminance detected by an illuminance sensor 33 approaches the target value, based on a target value of the illuminance of the light in an irradiation space which contributes to the growth promotion of a cultivating plant according to the cultivation time which is preset for the cultivating plant as well as the illuminance detected by the illuminance sensor 33.SELECTED DRAWING: Figure 2 【課題】育成期間に渡り好適な照度で植物の栽培を行え、且つ収穫量の再現性が高く、しかも植物栽培用照明装置の消費電力を大幅に低減できる植物栽培装置及び植物栽培方法を提供する。【解決手段】光反射層26及び反射板27,29によって、反射面を備え且つ反射面を栽培空間領域側に向けて、栽培空間領域を囲む六面を構成する六面構成部材が構成する。照明装置制御部35は、栽培用植物に対して予め設定した栽培時間に応じた栽培用植物の生長促進に寄与する照射空間内の光の照度の目標値と、照度センサ33によって検出した照度とに基づいて、照度センサ33により検出する照度を目標値に近付けるように植物栽培用照明装置25の光源から照射される光束を制御する。【選択図】 図2
