[目的]探究周麦22在小麦/玉米一体化条件下，周年氮肥用量及分配比例。[方法]研究周麦22在不同氮肥量及不同分配比例下的生长及产量变化规律。[结果]随全年氮肥施用量及氮肥由玉米向小麦分配率的增加，周麦22群体生理指标呈现增加趋势，而产量呈先增后降低的变化趋势。[结论]小麦玉米一体化全年施氮肥600 kg/hm2及5∶5的分配比例，有利于周麦22及全年高产。
[目的]探究週麥22在小麥/玉米一體化條件下，週年氮肥用量及分配比例。[方法]研究週麥22在不同氮肥量及不同分配比例下的生長及產量變化規律。[結果]隨全年氮肥施用量及氮肥由玉米嚮小麥分配率的增加，週麥22群體生理指標呈現增加趨勢，而產量呈先增後降低的變化趨勢。[結論]小麥玉米一體化全年施氮肥600 kg/hm2及5∶5的分配比例，有利于週麥22及全年高產。

Objective] ln this study, the aim was to explore the annual dosage and al ocation proportion of nitrogenous fertilizer for Zhoumai 22 in the condition of wheat-maize integration. [Method] The rules of growth and yield variation of Zhoumai 22 under different dosages of nitrogenous fertilizer and different distribution ratios were studied. [Result] With the increase of nitrogenous fertilizer application and distribution rate from maize to wheat, the physiological indexes of Zhoumai 22 population showed an increasing trend, while the yield presented the variation trend of increasing firstly and decreasing then. [Conclusion] Annual amount of nitrogenous fertilizer of 600 kg/hm2 and the distribution ratio of 5:5 in the condition of wheat-maize integration was beneficial to the high yield of the whole year ’s crops and Zhoumai 22.
