To provide a plant cultivation method and a plant cultivation system for increasing a functional component contained in a plant.SOLUTION: A plant cultivation system comprises: a supply part for supplying liquid to roots of a plant having an edible part; and an irradiation part for irradiating the plant with artificial light, and raises a plant. The supply part supplies liquid with reduced nitrate nitrogen in a nitrate reduction period (4 to 6 days for example) immediately before cropping the plant. The irradiation part continuously irradiates the plant with artificial light in which the intensity of light in a blue wavelength region is stronger than light in a wavelength region of other colors and which entirely has a wavelength region of visible light to show white color, in a light treatment period P3 immediately before cropping the plant.SELECTED DRAWING: Figure 7 【課題】植物に含まれる機能性成分を増加させるための植物栽培方法及び植物栽培システムを提供する。【解決手段】可食部を有する植物の根に液体を供給する供給部と、植物に人工光を照射する照射部とを備え、植物を生育する。供給部は、植物の収穫直前の硝酸低減期間（例えば４日〜６日間）において、硝酸態窒素を低減した液体を供給する。照射部は、植物の収穫直前の光処理期間Ｐ３時において、青色の波長領域の光の強度が他の色の波長領域の光よりも強く、かつ可視光の波長領域を全体的に有して白色を呈する人工光を、植物に連続して照射する。【選択図】図７
