| 摘 要： | 通过盆栽试验探讨东莞桥头农科园赤红壤中Ｃｕ、Ｚｎ对菜心生长的影响，结果表明：土壤Ｃｕ、Ｚｎ施用量同时增加，菜心地上部产量随之下降，Ｃｕ或Ｚｎ含量变化则表现为促进与抑制共存的混合过程；单施Ｃｕ或Ｚｎ均可抑制菜心生长及提高相应元素含量，并随用量增加先抑制后促进另一元素含量。

| Abstract: | 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. |
