[目的]为探索机械播种条件下,旱地小麦最佳的播种方式.[方法]采用常规条播(对照)、宽幅匀播、苗带播种、免耕沟播4种播种模式.研究播种方式对不同土层深度播前墒情、小麦出苗质量、越冬期小麦生长、小麦产量及其构成因素、生产成本、种植效益的影响.[结果]常规条播产量最高;免耕沟播省事省工、出苗齐全、产量高、收益最好.[结论]该研究为促进农机、农艺融合,高质量、规范化播种提供技术支撑.%[Objective]To find out a best sowing mode of dry-land wheat under the condition of mechanical seeding condition.[Method]The four sowing modes were adopted,including conventional drilling(CK),broad-row mix sowing,seedling belt sowing and no-tillage furrow see-ding.Effects of different sowing modes on the soil moisture before sowing at different soil depths,emergence quality of wheat seedlings,wheat growth at wintering stage, wheat yield and its component factors, production cost and planting return were studied.[Result]Conventional drilling had the highest yield, while no-tillage furrow seeding saved labor, had high yield, good earnings and complete seedling emergence. [Conclusion]This research provided technical support for promoting the integration between agricultural machinery and agriculture, and the high-yield and normalized seeding.
