Phytoremediation of heavy metal contaminated soil using fast-growing woody plants is the most economical and effective measure for large-scale soil heavy metal pollution in the world
.

Willow has strong tolerance and enrichment ability to a variety of heavy metals, and is an ideal plant material for phytoremediation

Recently, the Ecological Restoration Research Group of the Research Institute of Subtropical Forestry, Chinese Academy of Forestry conducted a systematic study on the process and regulation of heavy metal soil-tree transmission
.

Related research results were published in "Forestry Science" and "Plant and Soil" ( Plant and Soil )

The Ecological Restoration Research Group has carried out systematic research on the process and regulation of heavy metal soil-tree transmission

The research team found in previous studies that the roots of Salix integra "Yizhibi" varieties have a strong ability to accumulate heavy metal lead

They found that lead is mainly distributed in the cortical cells of the root system and less transported to the central pillar; most of the lead is combined with the cell wall, and the cell wall is free of -OH, pectin and C—O/C—O—S groups in the cell wall.
The capture process plays an important role
.

This study revealed the role of the cell wall and its different chemical groups in the process of lead enrichment in willow roots, and provided theoretical guidance for the analysis of the heavy metal enrichment mechanism of woody plants and the promotion of phytoremediation of heavily contaminated soils with heavy metals
.

The research was funded by the National Natural Science Foundation of China
