| 摘 要： | 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/hm23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。

| Abstract: | 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. |
