The invention relates to a box body used for planting plants. The box body comprises a bottom plate, a plurality of wall plates, a culture box, a top cover and a luminous unit module, wherein the culture box is arranged between the bottom plate and the wall plates in a way capable of being forwards separated, the top cover is arranged on the top sides of the wall plates , the top surface of the top cover is provided with a module groove, the luminous unit module is separably arranged in the module groove of the top cover and can illuminate light rays towards the culture box, a luminous unit is modularized, and in addition, the luminous unit module is separably arranged on the top cover, so when the luminous unit is damaged through fault, only the luminous unit module needs to be singly replaced, the top cover does not need to be replaced together, further, the operation is convenient, and the environment-protection requirement is met.本創作係一種用於種植植物的箱體,其包含一底板、複數壁板、一培養盒、一頂蓋及一發光單元模組;培養盒可向前分離地設於底板及該等壁板之間;頂蓋設於該等壁板的頂側,頂蓋的頂面設有一模組槽;發光單元模組可分離地設於頂蓋的模組槽中,且可朝向培養盒照射光線;藉由將發光單元模組化,並且該發光單元模組可分離地設置頂蓋上,藉此當發光單元故障損壞時,僅須單獨替換發光單元模組即可,無需連帶替換頂蓋,進而方便作業及達到環保的訴求。22‧‧‧側壁板221‧‧‧觀景部222‧‧‧磁鐵30‧‧‧培養盒321‧‧‧植孔33‧‧‧注水蓋40‧‧‧頂蓋50‧‧‧前蓋板51‧‧‧鐵片52‧‧‧操作孔60‧‧‧發光單元模組65‧‧‧沉頭螺絲66‧‧‧頂塞
