摘　　要：重金属Ｃｄ－Ｚｎ对水稻的复合污染和生态效应周启星（浙江农业大学，杭州３１００２９）吴燕玉，熊先哲（中国科学院沈阳应用生态研究所，１１００１５）ＣｏｍｐｏｕｎｄｐｏｌｌｕｔｉｏｎｏｆＣｄａｎｄＺｎａｎｄｉｔｓｅｃｏｌｏｇｉｃａｌｅｆｆｅｃｔｏｎｒｉｃｅ...The study on compound pollution of Cd and Zn on rice plant shows that their compound pollution is more complicated than single pollution. The interaction of Cd and Zn results in a decrease of Zn uptake and an increase of Cd accumulation in rice plant. The effects of Cd-Zn compound pollution on rice growth, and on accumulation and distribution of Cd or Zn in it are of two different characters. Which depend on the Cd and Zn concentrations and their combinations in soil, and also on their locations in different parts of the plant. It is suggested that the compound pollution of Cd and Zn on rice plant is not an unitary additive or antagonistic effect.
