摘　　要：研究了沟播,垄作、平作3种种植方式对夏玉米生长发育及其最终产量的影响。结果表明,土壤垄作和沟播较平作处理促进了干物质积累,使叶面积指数增大,且沟垄栽培具有一定的集水作用,千粒重增加,单株地上部总干重增加,穗部性状较好,垄作和沟播产量比平作分别增产4.01%和2.27%。The experiment studied the effect of furrow planting, bed planting, flat planting on maize＇s growth and yield. The results showed that bed planting and furrow planting accelerated the accumulation of dry matter, make LAI bigger, and increase the grain weight. The spike characteristics is better and the final yield increase 4.01%, 2.27% than flat planting respectively.
