为了优化冬小麦氮肥和磷肥的适宜用量，采用田间试验，研究了氮肥和磷肥施用量对冬小麦产量的影响。结果表明：氮肥的施用量与冬小麦产量的二次模拟函数为 y＝-0．6611 x2＋20．091 x＋234．85，相关系数为0．9708，冬小麦产量达到最高时的氮肥施用量为228．0 kg·hm-2。磷肥的施用量与冬小麦产量的二次模拟函数为 y＝-0．5726 x2＋13．168 x＋340．4，相关系数为0．92195，冬小麦产量达到最高时的磷肥施用量为172．5 kg·hm-2。
為瞭優化鼕小麥氮肥和燐肥的適宜用量，採用田間試驗，研究瞭氮肥和燐肥施用量對鼕小麥產量的影響。結果錶明：氮肥的施用量與鼕小麥產量的二次模擬函數為 y＝-0．6611 x2＋20．091 x＋234．85，相關繫數為0．9708，鼕小麥產量達到最高時的氮肥施用量為228．0 kg·hm-2。燐肥的施用量與鼕小麥產量的二次模擬函數為 y＝-0．5726 x2＋13．168 x＋340．4，相關繫數為0．92195，鼕小麥產量達到最高時的燐肥施用量為172．5 kg·hm-2。
