Description

Technical Field

In addition, most pesticides are organophosphorus pesticides. When pesticides are sprayed on the soil, they will destroy the dynamic balance of the soil and cause the soil quality to decline. The contaminated soil will affect the growth and development of crops, resulting in reduced yield and quality. Phytoremediation is a restoration technology that utilizes plant degradation, metabolism, transformation and its rhizosphere microecological function, and has been successfully applied to the restoration of some organic polluted soils, that is, by planting plants, using root plants to absorb harmful substances in the soil, transferring pollutants in the soil into the plant body, and then removing pollutants from the soil by harvesting the plants.
