A kind of accommodating member promoting plant growth, with for plant storing and promotion plant growth. The accommodating member for promoting plant growth includes: an accommodating ontology and a luminescence unit. Accommodating body defining has an accommodating space to put plant. The light that luminescence unit issues is to the accommodating space irradiation towards accommodating ontology, and the light that luminescence unit issues exposes to 1 meter of the small what of longest light path for accommodating ontology. Wherein, luminescence unit includes that first LED light group and one of the sending feux rouges to promote plant growth rate issue second LED light group of the blue light to promote photosynthesis of plant, and the red wavelength range that the first LED light group is issued is 620 to 760 nanometers, the blue wavelength range that the second LED light group is issued is 360 to 480 nanometers.一種促進植物生長的容置件，用以供一植物置放且促進植物生長。所述促進植物生長的容置件包括：一容置本體及一發光單元。容置本體界定有一用以置放植物的容置空間。發光單元所發出之光線用以朝容置本體的容置空間照射，且發光單元所發出之光線照射至容置本體的最長光路徑小於1公尺。其中，發光單元包含一發出紅光用以促進植物生長速度的第一LED燈組以及一發出藍光用以促進植物光合作用的第二LED燈組，而第一LED燈組所發出的紅光波長範圍為620至760奈米，第二LED燈組所發出的藍光波長範圍為360至480奈米。
