Study on inhibiting the absorption of heavy metals by lettuce
In the continuous progress of modern agricultural technology, an innovative material, biochar, stands out for its excellent environmental remediation capabilities. This carbonaceous material, which is produced by the pyrolysis of organic matter under the condition of hypoxia, not only has a high specific surface area and porous structure, but also shows a strong heavy metal adsorption capacity. In the lettuce pot experiment, the application of biochar has become the focus of research, which has shown remarkable effect in reducing the content of heavy metals in the soil and improving the safety of vegetables.
