| Zusammenfassung: | The utility model discloses a soil water and nutrient loss simulation test device which comprises a soil tank rotationally connected to a bracket, a V-shaped runoff collecting tank is arranged at the front end of the soil tank, and a runoff outlet is formed in the closed end of the runoff collecting tank; a shed frame is arranged on the soil tank, a first rain shielding film is arranged on the shed frame, a horizontal supporting rod is arranged on the front side of the shed frame, a second rain shielding film is arranged on the horizontal supporting rod, and the second rain shielding film is located above the runoff collecting tank. The first rain shielding film is arranged, so that crops in the soil tank can be illuminated outdoors to grow, and meanwhile, the influence of natural rainfall is avoided; the runoff collecting groove can collect runoff on the surface of soil to form water flow and discharge the water flow from the runoff outlet, and the second rain shielding film can prevent rainfall from falling |
