The invention discloses a method for repairing Cd contaminated soil by intercropping herbs and swamp cabbage. The method can repair Cd contaminated soil through intercropping agronomic measures. The method comprises: intercropping herbs and vegetables in Cd contaminated soil to be repaired, and carrying out normal cultivation management so that the Cd content in harvested vegetables and soil is reduced. The vegetables are swamp cabbages. The herbs are sorghum hybrid sudangrass, sudangrass, pennisetum, ryegrass, indian lettuce, chicory, amaranth, clover, alfalfa or astragalus sinicus. The invention provides the technical scheme for repairing Cd contaminated soil by agronomic measures of intercropping herbs in a swamp cabbage field. The intercropped herb has high biomass and a rapid growth rate, can enrich heavy metals such as Cd and can effectively reduce Cd content of the contaminated soil. The method can provide a basis for synchronous safe production and restoration in the Cd contaminated farmland. The method is environment-friendly and has obvious ecological, economic and social benefits.
