The lead is a kind of severely-toxic polluting stuff to rice's growth and development, since the output and the quality of rice are both affected by the lead's content and existing form in the farmland soil. Five aspects are analyzed and summarized systematically in this paper such as the lead's existing form in soil, the absorption and enrichment rule of lead in rice, the effect of lead's pollution on the rice's growth and the physiological biochemical effect of rice under lead pollution, and rice's resistant mechanism toward lead pollution.
