A plant cultivation apparatus includes a support, a light source holder, and at least one light source unit for plant cultivation. The light source holder with a power receiving end is installed on the plant support, configured to cooperate with the plant support to raise or lower the light source unit relative to plants. The light source unit is configured to magnetically attach to the light source holder, thereby achieving an electrical connection with the power receiving side. In the process of growing plants, the light source unit can be easily and quickly replaced with another one according to the growth conditions of various types of plants.一種植物栽培裝置,包括一支撐架、一光源承載架、及至少一栽培用光源。光源承載架可升降地組裝於支撐架,且光源承載架上設有一電源接收端,栽培用光源藉由磁吸作用力與光源承載架固定接合,並同時與電源接收端形成導通。藉此,能依據各類植物的生長條件及需求,快速完成適合植物生長的光源的安裝與拆換。A‧‧‧植物栽培裝置10‧‧‧支撐架11‧‧‧支腳結構12‧‧‧鎖孔20‧‧‧光源承載架21‧‧‧前側支架22‧‧‧後側支架23‧‧‧電源接收端24‧‧‧植栽座30‧‧‧栽培用光源
