The invention relates to the field of environmental protection and discloses an ecological bag and a rock slope re-greening device. A preparation method of the ecological bag comprises the following steps: (1) mixing polypropylene fiber colloidal particles and anti-aging polypropylene master batches, so as to obtain a mixture; (2) heating and fusing the mixture of the step (1), carrying out extrusion to form filaments, and carrying out oiling, traction, crimpy cutting and drying formation, so as to obtain an anti-aging polypropylene short fiber; and (3) carrying out loosening, carding, lapping, needling, heat setting and winding on the anti-aging polypropylene short fiber, so as to obtain the ecological bag. According to the ecological bag and the rock slope re-greening device, the technical defects that an unaesthetic structure is formed, the ecological environment is easily damaged, and the covered structure is unsteady after a rock slope is covered by virtue of existing lattice girder method, slurry stone-
