Application of Phytoremediation in the Treatment of Heavy Metal Contaminated Soil

The soil overweight and currently used soil heavy metal pollution prevention measures were introduced,the basic principles of the plant repair for heavy-metal contamination of soil were explored,the comparison of common phytoremediation and chemical improvers for plantrepair was focused on and the phytoremediation research directions were discussed.The result showed that the phytoremediation technology had advantages of low cost,and less chance of secondary pollution and destruction of soil ecological environment,etc.
