[目的]探究小麦/玉米一体化条件下,周年氮肥用量及分配比例关系下,冬小麦群体生长及产量变化规律.[方法]以周麦22为材料,小麦/玉米两熟制周年氮肥用量设300、450、600 kg/hm2 3个水平,小麦、玉米间的氮肥分配设4∶6、5∶5、6∶4 3个比例.[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,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]冬小麦与夏玉米全年施氮肥(尿素)600 kg/hm2及5∶5的分配比例,有利于冬小麦及全年高产.

[Objective] To explore growth and yield variation law of winter wheat under the condition of wheat/corn integration,anniversary amount of nitrogen application and distribution.[Method] With Zhoumai 22 as material,wheat/corn two cropping system anniversary amount of nitrogen application set three levels of 300,450,600 kg/hm2,nitrogen distribution set three proportion of 4∶ 6,5∶ 5,6∶ 4.[Result] The results showed that with the increase of nitrogen application amount and the annual corn wheat allocation rate,physiological index of wheat population increased,but the yield increased first and then decreased.[Conclusion] The application of anniversary amount of winter wheat and summer corn nitrogen fertilizer (urea) 600 kg/hm2 and 5∶5 ratio is beneficial to the annual total yield and the yield of winter wheat.
