PROBLEM TO BE SOLVED: To suppress growth variation and quality deterioration of plants, and to efficiently obtain leaves of the plants.SOLUTION: In a method for cultivating a tea plant 10, a ratio of FR light (Far Read light) is increased in light emitted to the tea plant 10 during a new sprout formation period S11, and when the new sprout formation period S11 is over, the ratio of the FR light in the light emitted to the tea plant 10 is decreased compared with the light that has been emitted during the new sprout formation period S11.COPYRIGHT: (C)2014,JPO&INPIT【課題】植物の生育のばらつきや品質劣化を抑制し、効率よく植物の葉を収穫する。【解決手段】茶樹10の栽培方法では、新芽の形成期間S11には、茶樹10に照射する光におけるFR光の比率を多くし、新芽の形成期間S11を過ぎると、当該新芽の形成期間S11に照射していた光と比べて、茶樹10に照射する光におけるFR光の比率を少なくする。【選択図】図1
