摘　　要：【目的】为提高滴灌冬小麦产量,降低氮磷肥料的浪费。【方法】试验采用两因素不完全随机设计,研究石河子中高产田氮磷对滴灌冬小麦产量的影响。【结果】(1)在一定的范围内,施氮磷肥能够促进滴灌冬小麦增产,且二元二次拟合的相关系数达到0.99。(2)在研究条件下,二元二次模型更能综合反应氮磷对滴灌冬小麦的效应。(3)冬小麦的最高产量区间为氮水平200～360 kg/hm2,磷水平0～100 kg/hm2。【结论】因此,北疆中高产田滴灌冬小麦生产中应适量施用氮肥,控施磷肥,配施锌等微量元素肥料,以保证在取得高产的同时,获得较好的经济效益。【Objective】 In order to improve the production of winter wheat and reduce the waste of fertilizers.【Method】The yield of winter wheat were appraised by two factors test of N and P under drip irrigation in Northern Xinjiang.【Result】Major research conclusions are as follows： The yield of winter wheat increased with NP fertilization application.The correlation coefficient between grain yield and the NP application was 0.99.In the present study conditions,the binary quadratic model was more comprehensive to response to the effects of winter wheat by NP.【Conclusion】The demand for N and P of higher yield of winter wheat is 200-360 kg/hm2 and 0-100 kg/hm2.
