The invention discloses an environment-tensile loading-bending fatigue coupling test device for an FRP (Fiber Reinforced Plastic) rod and a test method of the environment-tensile loading-bending fatigue coupling test device. Comprising a metal pedestal, a servo motor, an eccentric cam, a driven roller, a driven ejector rod, a spring sleeve, a spring, a bending pressure sensor, a bending support, a holding and loading reaction frame, a height adjusting mechanism, a hollow pressure sensor, a hollow jack, a holding and loading gasket, an anchorage device sleeve, an anchorage device clamping piece assembly and an environment hose. The two ends of the driven ejector rod are fixedly connected with the hollow pressure sensor and the hollow jack respectively, the stretching and loading effect is achieved under the action of the hollow jack, the driven ejector rod drives the bent support to achieve vertical reciprocating simple harmonic linear motion under the action of the eccentric cam and the spring, and environmen
