Abstract | The invention provides a method for remedying soil polluted with cadmium by using interplanting. In the soil polluted with cadmium, cadmium high-accumulation plants and cadmium low-accumulation plants are planted simultaneously in an interplanting manner and planted alternatively at the number ratio of 1 to 1; four plants around each plant are all different from the plant in variety, the plant spacing is 10 to 30 cm and the line spacing is 10 to 30 cm; the plants are watered by using a water source without being polluted by heavy metal and the field moisture capacity of the soil is kept to be 80%; compound fertilizers and carbamide are applied, depending on the soil property and the crop variety; edible parts of the interplanted plants are harvested at the harvest time and the cadmium content in the plant variety with relative low cadmium accumulation is decreased to the specified safe standards for consumption in China, so that the purpose of yielding safe edible products from the soil polluted with cadmium |
