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。

摘  要:
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.
