冬小麦宽幅精播高产栽培技术是对小麦精量播种高产栽培技术的延续和发展,实现了农艺与农机相结合,其核心“扩大行距,扩大播幅,健壮个体,提高产量”。有利于提高个体发育质量,构建合理群体;对小麦前期促蘖,中期促穗,后期攻粒具有至关重要的 The broad-grain precision sowing and winter wheat cultivation technology is a continuation and development of high-yielding cultivation techniques for precision sowing of wheat and realizes the combination of agronomy and agricultural machinery. Its core is to “increase the space between rows, expand the sowing width, and improve the output of robust individuals.” Is conducive to improving the quality of individual development, to establish a reasonable group; on the early wheat tillering, mid-spike, late-stage agglomeration is essential
