摘要
采用田间试验方法研究了潮土区磷、铜配施对冬小麦产量和植株体内磷、铜养分含量的影响。结果表明:磷、铜配施对冬小麦产量和养分含量有明显的影响。铜肥以及磷铜交互作用对冬小麦的增产效应达到1%显著水平,P1Cu1处理(即施磷肥90 kg hm-2、铜肥22.5 kg hm-2)为获得冬小麦最高产量的适宜配施组合。不同磷水平下,磷铜之间的相互作用不一致,冬小麦植株体内磷、铜养分含量的变化也表现各异。低磷条件下,磷铜之间表现为相互促进作用,高磷条件下,则表现为相互抑制作用。
The effect of copper,phosphorus and the interaction on yield of white-wheat in Chao soil was studied in the field experiment,.The results showed that effect of copper and the interaction of phosphorus and copper on the grain yield increasing reached the extremely remarkable level,phosphorus had no remarkable effect on the yield.P1Cu1（phosphorus fertilizer application was 90 kg ha^-1,and copper application was 22.5 kg ha^-1） was the appropriate treatment for grain yield.There was antagonistic action between copper and phosphorus.Under different phosphorus levels,there was different interaction between phosphorus and copper,the content of phosphorus and copper in wheat varies.phosphorus and copper can promote each other in lower phosphorus level,contrarily restrain each other under higher phosphorus level.
