EFFECTS OF SELENIUM ON UPTAKE AND DISTRIBUTION OF TRACE ELEMENTS AND HEAVY METALS IN MILLET

Se is an essential trace element in human and animal life activities. Chinese is more like to supplement selenium by food. Millet an important coarse cereals crop in China, was selected as the tested crop because no reports on selenium rich millet are found. In addition to the selenium content of selenium, the effects of selenium on other trace elements and heavy metals content were also studied. The results showed that 1) Selenium fertilizer can promote selenium accumulation to millet grain;2) Se can improve Fe and Zn contents in both millet grain and millet straw and Se is synergistic with Fe and Zn; 3) Se can inhibit the content of Cd and Pb in millet grain, the more selenium fertilizer the more decrease of heavy metals Cd and Pb.
