Study on the transport of heavy metal lead in cabbageand the influence of cabbage growth with organic fertilizer

摘要

In the test, we adopted the method of potted plant cultivation to research that how theorganic fertilizer influences on the growth of plants in the soil as regards to different concentrationof lead pollution and analyze the transport of lead in soil and plants system. In each group, The roottolerance index (RTI) and transport factor (TF) of plant were analyzed. The results showed that theroot of the plant had great effect on the lead pollution. After its root contacted lead, most of the leadwere kept in root, rather than moving. The quantity of lead of plant including ground andunderground were measured. The results showed that the quantity of lead in underground was toomuch higher than the quantity on the ground.
