摘要
玉米高产创建栽培技术一直是国内外玉米专家研究的热点。通过汇总国内外专家在玉米高产创建方面取得的成绩,得出高产玉米需要关注的2大主要生理指标——不同生育期地上部干物质的变化和不同生育期叶面积指数(LAI);最后总结出玉米高产体系栽培技术:选择合适的品种;选择播种期及播种密度,构建适宜的植株群体结构;培肥土壤和充足的水肥供应;精细播种,加强田间管理,适期收获。
In recent years,many scholars have done a lot of research about how to create high-yielding corn.Through summarizing domestic and foreign experts achieved some success in the corn to create high-yielding,this paper draws high-yielding of corn need to focus on two main physiological indicators aerial dry matter and leaf area index(LAI) at the different growth stages.Cultivation technology for high-yielding of corn system were concluded as bellow: the right variety selection;the right sowing and planting density selection;a suitable plant population structure building,soil fertility improvement and adequate supply of water and fertilizer,and precise sowing;field management strengthening and the right date harvesting selection.
