【摘要】 为实现玉米产量潜力的进一步提高,结合玉米科研和高产开发实践就中国各玉米高产栽培技术研发阶段的具体技术、技术实质、技术创新点、高产攻关途径进行了分析探讨,明确了今后实现进一步玉米高产栽培攻关目标的技术途径。结果表明:在对玉米进行遗传改良的同时对玉米进行密植和营养(群体冠层的和土体的)同步改良是当代玉米高产开发中实现玉米产量潜力持续增进、实现玉米高产栽培攻关目标的根本途径。更多还原

【Abstract】 The technique content,the crux of the technique,technique promoting point,high yield ways of China maize high yield cultivating technique has been discussed with the research and practice of maize high yield developing in this paper.It is more clear about the technique way for attain the aim of maize yield further.The result indicated: Make the maize close planting and nutrition coordinate improvement(in mass canopy and soil)at the same time of maize genetic improvement is the key technique way for achieve the aim of maize high yield planting and developing maize high yield potential continually.更多还原
