铜氮配施对冬小麦籽粒产量和蛋白质含量的影响

在豫中潮土区通过田间裂区试验研究了铜、氮配施对冬小麦籽粒产量和蛋白质的影响。结果表明,氮肥对冬小麦籽粒产量和蛋白质产量影响达极显著水平,对蛋白质含量影响不显著。铜肥对籽粒产量和蛋白质产量的影响都达到极显著水平,对籽粒蛋白质含量影响达显著水平。氮、铜交互对冬小麦籽粒产量和蛋白质产量影响达极显著差异,对蛋白质含量影响也达显著差异。综合考虑产量和蛋白质因素,本试验条件下,铜、氮配施以N1Cu2处理(即施氮120 kg.hm-2,施铜45 kg.hm-2)为适宜的铜、氮配施比例。

Effects of combined application of copper and nitrogen on grain yield and protein in winter wheat

For guiding for the fertilizer application,the effects of copper and nitrogen fertilizer cooperation application on grain yield and protein content of winter wheat through field experiment in Meadow soil in middle Henan Province was studied.The results showed that N fertilizer affected the yield and protein yield extremely,and had no remarkable effects on protein content.Cu fertilizer and the interaction of Cu and N had extremely remarkable effects on the grain yield and protein yield,and affected protein content remarkably. Under the conditions of this experiment,the N1Cu2 treatment was the most appropriate for grain yield and protein content and protein yield.
