Pot experiments were carried out to determine the effects of applying Cu,Zn to the latored soil on the growth of Chinese flowering cabbage ( Brassica parachinensis Bailey) in Qiaotou Aficultural Garden,Dongguan city. The results showed that the plant weight decreased with applying Cu and Zn to the soil simultaneously, and that the change of plant Cu or Zn content was a process combining rise with fall. Enhancing the dose of Cu or Zn separately dropped the plant weight but increased the element content in plant. Another metal content could be reduced initially and then raised.
