The invention relates to an application of
eupatorium adenophorum spreng to repairing heavy
metal zinc, lead and
copper contaminated mining area soil, which comprises the following steps of: planting the
eupatorium adenophorum spreng in the heavy
metal zinc, lead and
copper contaminated mining area soil in which the
eupatorium adenophorum spreng is widely distributed, absorbing and accumulating
heavy metals by utilizing plants of the eupatorium adenophorum spreng according to the enrichment characteristics of heavy
metal zinc, lead and
copper and transporting a majority of
heavy metals to the parts of the plants on the ground; and harvesting the parts of the plants on the ground before seeds of the eupatorium adenophorum spreng are mature to prevent the seeds of the eupatorium adenophorum spreng from being blown in the wind and spread to the outside of a mine,
ashing the parts of the plants on the ground and extracting the
heavy metals to achieve the purpose of repairing the heavy metal zinc, lead and copper contaminated mining area soil. As the eupatorium adenophorum spreng has exuberant
vitality and large
biomass and can reduce the concentration of the heavy metal zinc, lead and copper in the
rhizosphere soil of the eupatorium adenophorum spreng through a mechanism of the eupatorium adenophorum spreng to protect the eupatorium adenophorum spreng against heavy metal damage and normally grow, when the eupatorium adenophorum spreng is applied to the repairing of the heavy metal zinc, lead and copper contaminated mining area soil, the cost is low, and the repairing potential is large.
