Rational application of nitrogen and phosphorus is one of the main pathways to enhance wheat yield. The optimum dosage of nitrogen and phosphorus used in different precipitation patterns was studied using the binary quadratic regression equation, which could provide a basis for fertilization of wheat in Loess Plateau. The results showed that the amount of nitrogen and phosphorus ferti-lizer required for the maximum yield was dependent on precipitation patterns. The maximum wheat yield in normal years was 4229 kg·hm合理施用氮磷化肥是提高小麦产量的主要措施之一.用二元二次回归方程探讨不同降水年型下的氮磷优化用量,为黄土旱塬小麦施肥提供依据.结果表明: 不同降水年型小麦最高产量所需要的氮磷肥用量不同,平水年小麦最高产量4229 kg·hm |
