| titleOfInvention | Method for restoring farmland soil polluted by cadmium by utilizing aromatic plants and efficiently utilizing cadmium |
| abstract | A method for restoring and efficiently utilizing cadmium-polluted farmland soil by utilizing aromatic plants, which adopts the aromatic plants to plant on the cadmium-polluted farmland soil, comprises the following steps: seedling raising is carried out by adopting aromatic plant peppermint or lemongrass; planting the aromatic plant seedlings after seedling culture to the cadmium-polluted farmland soil; harvesting mature aromatic plants and leaving piles; applying common rhodamine fertilizer to the cadmium-polluted farmland soil after harvesting, watering thoroughly, and weeding in time during the growth period; the harvested products are treated in a centralized way; the peppermint and lemongrass are planted for 1 time in a mutual rotation manner on farmland soil with severe cadmium pollution every 3 years, and the process of centralized treatment of the output is to extract essential oil from the output by adopting a steam distillation method. The method provided by the invention not only overcomes the defects and shortcomings of the existing remediation technology for the farmland soil with severe cadmium pollution, but also is safe and environment-friendly, can gradually remediate the farmland soil with cadmium pollution, and can bring higher economic benefits. |
