Description

technical field

[0001] The invention relates to a method for repairing cadmium-contaminated soil by using Aspergillus polypolyps in combination with Indian mustard, and belongs to the technical field of microorganisms. Background technique

[0002] In modern times, with the rapid development of industry and agriculture, heavy metals have been used more and more widely, and the accompanying pollution problems have become more prominent. As the largest storage place for heavy metal pollutants, soil heavy metal pollution has become one of the global environmental problems. Therefore, soil heavy metal pollution, especially farmland soil heavy metal pollution, urgently needs to be prevented and restored.

[0003] The sources of cadmium in the soil are mainly the mining and smelting of lead-cadmium ore, and the discharge of industrial "three wastes" in the electroplating industry. At present, the area of ​​China's cultivated land polluted by heavy metals such as cadmium and cadm...
