Effect of the Intercropping Treatment on Heavy Metal
Uptake in Plants.
It has been reported that the intercropping could enhance the availability
and uptake of plant nutrients and produce substances promoting plant growth. Our result indicated
that the intercropping can increase the biomass ryegrass. Means that the intercropping can increase
the yield of ryegrass in the process of phytostabilization.
Conclusion
The ryegrass under the influence of Zn and Pb showed good growth and development, despite
the high concentration of these metals in the investigated compounds, indicating the high resistance
of these metals, especially for Zn. Ryegrass can be considered a viable candidate for Zn
phytostabilization and Pb-phyto-extraction in soils in the short and medium term. This species may
contribute to the recovery and restoration of degraded areas by extraction and improve soil
condition by reducing soil acidity and increasing organic matter content. We believe that the results
of this study can make a new contribution to our understanding of the tolerance, absorption,
bioaccumulation and translocation potential of ryegrass.
