Method for repairing cadmium-polluted farmland by using corn and alfred stonecrop intercropping

The invention discloses a method for repairing a cadmium-polluted farmland by using corn and alfred stonecrop intercropping. The method comprises the following steps: (1) in the cadmium-polluted farmland soil, planting corn seedlings and alfred stonecrop seedlings by using an intercropping mode, dressing a nitrogen phosphorus and potassium compound fertilizer and an organic fertilizer for promoting the growth of the corn and alfred stonecrop; (2) within a week after dressing the fertilizers, spraying oilseed rape root extracting solution to the root of the alfred stonecrop, harvesting the alfred stonecrop regularly, and harvesting the corn after the corn is matured; the preparation process of the oilseed rape root extracting solution comprises the following steps: a, pounding the fresh oilseed rape root, soaking in water, heating and boiling for more than 1 h, cooling soaking liquid to the room temperature, and stewing for more than 24 h; and b, after stewing, separating solid and liquid, and taking a liquid phase which is the oilseed rape root extracting solution. The method is capable of realizing a corn and alfred stonecrop intercropping technology, through spraying the oilseedrape root extracting solution to the root of the alfred stonecrop, overcoming the problem in the prior art that the Cd content in the corn is still high after the corn and alfred stonecrop intercropping and the plant removal rate of Cd in the soil is not high.
