摘　　要：2020年中国农业科学院作物栽培与生理创新团队在新疆奇台创造24948.75 kg/hm2的玉米产量,刷新全国玉米高产纪录。研究团队采取玉米密植高产栽培技术,在膜下滴灌、水肥一体化生产条件下,4月14日播种,宽窄行70 cm+40 cm配置,播种密度135000株/hm2,产量最高的品种是MC670,收获穗数129630穗/hm2,穗粒数549.4粒,千粒重378.0 g,单穗粒重193 g。本文总结高产纪录玉米田生产过程的主要管理环节和高产群体的主要指标,为玉米高产提供参考。In 2020,crop cultivation and physiology innovation team of the Chinese Academy of Agricultural Sciences created a yield of 24948.75 kg/ha in Qitai,Xinjiang,once again setting the national high-yield maize re⁃cord.The research team adopted maize higher population and high-yield cultivation techniques,under the condi⁃tions of drip irrigation under mulch and integrated water and fertilizer production,sowing on April 14,with a wide and narrow row of 70+40 cm configuration,a seeding density of 135000 plants/ha,and the highest yield variety was MC670.The ears number,grains number per ear,1000-kernel weight and grain weight per ear were 129630 spikes/ha,549.4,378.0 g,and 193 g,respectively.This article summarized the main management links in the pro⁃duction process of high-yield maize fields and the core indicators of high-yield groups,to provide reference for maize practitioners.
