| 摘 要： | 为应对气候变化,改变传统种植模式,以冬小麦长6359为试验材料,采用二因素随机区组设计,研究了播期、播量对冬小麦产量及产量构成因素的影响。结果表明:冬小麦长6359的播期在9月25—30日的范围内可适当进行调整,在传统播期9月25日的基础上可延后5 d左右;播量在187.5～277.5 kg/hm2范围内结合播期进行调整,可适当减少播量。受全球气候变暖的影响,针对传统种植模式进行适当调整是当前小麦高产高效栽培的必要措施。

| Abstract: | In response to climate changes and on purpose to change traditional cropping pattern, effect of the sowing date, seeding rate on Wheat yield and yield components in winter wheat Chang 6359 was studied in two factor cmdonized block design. The results showed that： The sowing date of winter wheat Chang 6359 adjustments was in the scope of September 25-30, and 5 days or so might be delayed based on the traditional seeding date on September 25; Seeding rate might be appropriated in 187.5 ~ 277.5 kg/hm2 combined with the sowing date, and a little seed rate adjustments could be made. Therefore, proper adjustment for the traditional cropping pattern is highly necessary for high efficient wheat farming under the impact of the global wanning. |
