重金属污染土壤对植物伤害研究

Study on Injuring Plants by Soil Polluted by Heavy Metals

多年来,由于工业三废的排放及城市生活垃圾、污泥及含重金属的农药、化肥的不合理使用,使土壤受到污染,其中,重金属污染较为突出。从土壤环境污染的特点和重金属在土壤—植物体系中的迁移着手,详细地阐述了重金属对植物伤害效应及伤害机理。

The soil has been polluted for many years because of the discharge of the industrial three wastes,town rubbish,sludge,and unreasonable usage of pesticides containing heavy metals and chemical fertilizers.Among them,the heavy metal pollution is comparatively outstanding.This text starts with the characteristics of the soil environmental pollution and the transplant of the heavy metals between soil and plants,and explains in detail the effect and mechanism of heavy metals injuring plants.
