Study on the optimum growth density of Oenothera glazioviana
and its adaptability to copper, lead and zinc contaminated soil
Abstract：Soil heavy metal pollution problem is increasingly serious, copper, lead, zinc pollution soil remediation has become a hot topic in recent years. In this paper, the optimum planting density and the growth status of Cu, Pb and Zn polluted soils were studied by studying the optimum planting density of Osmanthus hibiscus and the resistance of three heavy metals in copper, lead and zinc. And has a further guiding role in the study of plant remediation of heavy metal contaminated soil. The results showed that the planting distance of the plants was 0.5 m ~ 1 m. From the growth and development of the plants, the planting density can be chosen to be about 3500 per acre. The distribution of copper, lead and zinc in the grass of the herbaceous plants was above that in the shoots> aboveground> seeds. The transport capacity of copper on the copper was proportional to the copper content in the soil, and the copper content was too high. Of the copper transport coefficient decreased; the northern part of the grass to see the grass to the ground and the seeds of lead and zinc transport capacity is weak; yellow grass grape seed in the heavy metal content is very low, both in the range of 10 ~ 30mg / kg, The herb has a certain absorption capacity for copper, lead and zinc, and the content of heavy metals in the seeds is low, which can be used as a repair plant for the treatment of copper, lead and zinc pollution and safe economic crops.
