Phytoremediation method for pentachlorophenol contaminated soil

The invention provides a phytoremediation method for soil pentachlorophenol pollution. The phytoremediation method comprises the following steps: selecting salix babylonica, conyza canadensis and alfalfa as plants; detecting the content of pentachlorophenol in the to-be-remediated soil; planting the salix babylonica in the pentachlorophenol contaminated soil; carrying out mixing sowing on conyza canadensis and alfalfa seeds among plant rows of the salix babylonica. Through the provided phytoremediation method for the soil pentachlorophenol pollution, pentachlorophenol contaminated soil can besimply and quickly remediated. 本发明提供一种土壤五氯苯酚污染的植物修复方法，包括如下步骤：所选用植物为垂柳、小飞蓬及苜蓿；检测所需修复土壤五氯苯酚的含量；把垂柳种植在五氯苯酚污染土壤上；小飞蓬和苜蓿种子混播，播种在垂柳的株行间。采用本发明提供的土壤五氯苯酚污染的植物修复方法，可以简单快速修复土壤五氯苯酚污染。
