Plant cultivation device for environmental governance and cultivation method thereof

The invention belongs to the technical field of plant cultivation, and discloses a plant cultivation device for environmental governance and a cultivation method thereof.The plant cultivation device comprises a storage frame, cultivation barrels are arranged on the two sides of the storage frame, the lower portions of the outer surfaces of the cultivation barrels are fixedly sleeved with bottom pipes, and one ends of the bottom pipes are fixedly sleeved with the storage frame. According to the device, excessive water flow is effectively guided to be matched with the guide frames with different lengths to quickly guide overflowed water flow into soil with different depths of the cultivation barrel, efficient permeation irrigation is achieved, meanwhile, waste caused by overflow of the water flow is avoided, and the water flow for continuous irrigation can be guided out and stored through the bottom pipe; the water-saving irrigation device is simple in structure and convenient to use, the control difficulty of
