摘　　要：以近期全国高产超高产玉米群体为基础,概述了高产超高产群体质量为:大群体(平均密度为1 hm295 850株,平均叶面积指数为7.3)、高积累(干物重大于30 000 kg/hm2)和多转化(粒叶比大于2.50)是形成高产超高产玉米群体的基础。重点阐述了中国精确栽培技术研究现状,并对精确栽培技术在玉米高产超高产上的应用提出了建议,旨在为精确栽培技术在玉米生产上的推广提供理论依据。Based on the super high yield maize populations reported in recent years, this paper summarized the basis of the maize population of super high yield, which is, large population （ average density of 95 850 plant per hm2 and average leaf area index of 7. 3 ） , high accumulation （ dry weight more than 30 000 kg/hm2 ） and more conversions （ gain-leaf ratio greater than 2. 50）. The current research status of precision cultivation were reviewede and its application in maize for super high yield were suggested, which would provide a theoretical basis for the promotion of maize production.
