The Intercropping Influence on Heavy Metal Uptake for Hyperaccumulators

Phytoremediation is the use of living green plants for in situ risk reduction and/or removal of contaminants from contaminated soil. Phytoremediation is an energy efficient, aesthically pleasing method of remediating sites with low to moderate levels of contamination. Phytoremediation in the actual application process, there is a longer time to repair, the repair efficiency is not high. Intercropping is the practice of growing two or more crops in proximity. A new approach, intercropping system was introduced to phytoremediation pollutants from contaminated soil. The paper makes a review on current research and development on intereropping system in soil. Hyper accumulator intercropping systems play a role in the following areas: affect the root exudates and the activity of heavy metals on soil. Changes in aboveground biomass system and root morphology and root activity.
