The invention provides a twenty-five-roller stretcher for uniaxial tension of geogrid, belonging to the processing field of plastic state materials. According to the stretcher, a multiroll type multi-point stretching manner, oil heating, whole-course chain drive are utilized, and the tension speed of the front stage and the rear stage can be adjusted by a chain wheel, so that the condition that the weight of a stretching roller is increased and the rotational inertia of the stretching roller is large after the stretching roller is fully filled with hot oil, so that a driven roller of an existing stretcher is difficult to control and is even out of control, and further the tension precision is affected can be avoided, and further various problems related to cost, processing, control and other aspects caused by gradually increased size of the rear-stage stretching roller in the prior art can be also avoided, so that plates can be stretched on each stretching roller, the multi-roller multi-point stretch is realized, the manufactured geogrid can be stretched more uniformly, the thickness of the geogrid is uniform and consistent, the molecular orientation linear distribution is uniform, and the node intensity is high; and the twenty-five-roller stretcher for the uniaxial tension of the geogrid has quite high stretch strength and stretch modulus, and technological requirements on the lateral stretching of the later-stage geogrid are met.
