[0023] In a specific embodiment of the utility model, a universal brake wheel 3 is provided at the bottom of the support plate 1, so that the movement of the experimental device is more labor-saving; the interior of the box 2 is filled with contaminated soil, and plants are planted inside the soil. The microbial agent or water is transported to the liquid distribution pipe 8 through the liquid delivery pipe 10, and the microbial agent or water is thrown into the soil by the nozzle 9. The soil is repaired by the combined action of microorganisms and plants, and the soil pollution is regularly tested to know the repair effect. When watering the plants, according to the height of the plants, the adjustment mechanism is operated to keep the movable rod 6 at a suitable height and fix it, and then the cross bar 7 is pushed. The cross bar 7 drives the insert tube 12 to move through the movable rod 6 and the support tube 5.
