在景电灌区和引大灌区分别以春小麦品种宁春39号和永良15号为指示作物，比较了宽幅匀播与常规条播2种方式下不同播种方式的春小麦主要性状及产量。结果表明，与常规条播处理相比，宽幅匀播均能够明显促进小麦分蘖，增加穗长，提高单位面积结穗数和千粒重，增产率在10%以上，可在甘肃中部引黄灌区示范推广。

Two spring wheat variety， Ningchun 39 and Yongliang 15， are employed in this research， in order to investigate the effect of different sowing pattern on main characters and yield of spring wheat in the Yellow River Irrigation Area of central Gansu province. The result shows that compared with the conventional drilling processing， wide precision seeding can significantly promote tillering， increase of ear length， ear number per unit area increased and grain weight， yield increasing rate is more than 10%， which could be demonstration and extension in the Yellow River Irrigation Area of central Gansu province.
