摘要：

在黄淮平原小麦玉米一年两熟、玉米收获后秸秆机械化直接还田条件下，采用播量、播深和镇压三因素裂区试验，研究了不同播种方式对小麦品种济麦22的出苗、越冬及产量表现。结果表明：播量因素显著影响出苗率、越冬率、产量及其构成因素穗数和穗粒数，对以上指标的作用力均在30%以上；镇压极显著影响越冬率，作用力占14.02%；播深对以上各指标均无显著影响。在本试验条件下，播量225万/hm2基本苗，播深4-5cm，播后镇压处理的播种方式，可保证小麦高质量出苗及安全越冬，达到高产稳产的目的。

Abstract:

The studies were conducted on the effect of different seeding manner on the seedling emergence over-winter and yield of the wheat cultivar “Jimai 22” under the maize-wheat double cropping system and maize stalk full returned to the fields in the Huang-Huai Plain. The results showed that sowing rate is the main reason which significantly affected the seedling rate, over-winter rate, yield, and yield composition. The affecting force is more than 30%; Compacting has extremely effect for the over-winter rate, the affecting force is 14.02%; Sowing depth has no any extremely effect for all the test index. Combining the sowing rate, sowing depth, and compacting, it can be concluded that the best combination is 2250000/hm2 seedling，4-5cm sowing depth, and compacting in order to make sure the seedling emergence rate, over-winter rate and grain yield.
