摘要
对起巷小麦产量不稳的状况进行了试验研究。结果表明，盲目加大播量是造成赶茬小麦产量不稳的重要因素之一，迟中争早，早稀晚密，适当加大播量是夺取小麦高产稳产的关键。增磷稳氮，促控结合是赶茬小麦夺取高产的保证。该项技术在保证小麦高产稳产的基础上，可为夏播作物延长5～10天的生育期，使山西中部平川一年二作成为现实。
It is a common practice in the middle part of Shanxi province that wheat is sown as soon as the previous crop is harvested in the late autumn. The result in this study shown that blindly enlarged seeding rate is one of the major factors affecting the yield and yielding stability.New methods of enhancing the local wheat productivity was suggested.
