The invention discloses a method for repairing cadmium-contaminated soil by using Salix integra. According to the present invention, based on the growth characteristics of rapid growth and multi-yearharvesting after one-year cutting of the Daqingye variety of Salix integra, by synergistically the adding of active carbon to soil and the spraying of spermidine, the cutting propagation and root system forming of Salix integra in cadmium-contaminated soil is promoted, and the transport and enrichment ability of Salix integra to cadmium is improved, such that the ecological restoration of cadmium-contaminated soil is achieved; with the method, the influence of two treatments with active carbon and spermidine on Salix integra under cadmium stress are defined, and the effect of spermidine in theenhancing of cadmium tolerance and the effect of active carbon in the adsorption fixing of soil cadmium are investigated; and the harvested Salix integra wicker can be used as a wicker material, suchthat the ecological benefits are achieved while a certain economic benefit can be created.
