氮磷肥不同配比对冬小麦产量的影响

[目的]提高小麦产量,增加农民收入。[方法]通过田间试验,研究不同的氮磷肥配比对小麦产量的影响。[结果]结果表明,增施氮肥对冬小麦的株高和穗长均有明显的促进作用;其中处理N2P4获得了最大的千粒重和实际产量,较对照分别增加了27.4%和67.9%,初步定为最优组合,其他处理N3P1、N3P2、N2P3、N2P2、N2P1和N1P3也较优。[结论]该研究为指导农业生产提供了一定的理论依据。

Effects of Different Quota with Application Nitrogen and Phosphor on Winter Wheat Yield

[Objective] The study aimed to enhance wheat yield and increase income of farmer.[Method]The effects of different quota with application nitrogen and phosphor on wheat yield were studied according to field experiment.[Result]The results showed that increasing nitrogen application obviously promoted plant height and spike length of winter wheat.Treatment N2P4 obtained the highest values of thousand kernel weight and actual yields which increased 27.4% and 67.9%,respectively,and this treatment was preliminarily determined the best association.The other treatment N3P1、N3P2、N2P3、N2P2、N2P1 and N1P3 were better.[Conclusion]This study will provide theoretical basis for instructing agricultural production.
