The invention provides a greening plant brick and a manufacture method thereof. A brick body of the plant brick consists of a frame body, a lining plate (1), a water-proof layer (2), a nutritive substrate (6), a drip irrigation tube (5) and a humus layer (7), wherein the frame body consists of a surrounding frame (3) with the bottom surface, a support rod (4) and a frame cover, and the frame cover consists of a reticular insulation layer (8), a water absorbing layer (9) and a lattice framework (10). Plants can be cultured in an early stage, and then are transplanted into the brick, the survival rate is high, and the goal of fast greening of vertical buildings can be reached. At the same time, because the plant brick is provided with a parallel connection type drip irrigation device, water, fertilizers, pesticide and the like can be conveniently and fast supplied to the plants, and the maintenance and management efficiency can be improved. The plant brick has wide application range, can be applicable to the greening of internal and external walls of buildings such as channels and the like, rock slopes and the like.
