近年来,随着各地紧凑型玉米杂交种的应用和规范化栽培技术的推广,紧凑型玉米在生产上发挥着重要的作用。虽然产量逐年提高,面积逐年加大,但与亩产750～1000千克的攻关田、展示田相比仍然没有发挥紧凑型玉米增产的巨大潜力。探讨其原因,大面积生产中存在着几个不可忽视的问题,突出表现以下几点。 In recent years, compact corn has played an important role in production with the promotion of compact corn hybrids and standardized cultivation techniques. Although the output has been increasing year by year and the area has been increasing year by year, it still has not had the huge potential to increase the yield of compact corn compared with the Gongguan and 750,000 mu per mu yielding 750-1000 kg per mu. Explore the reason, there are a few large-scale production can not be ignored, highlighting the following points.
