摘  要：
为明确定向播种技术对玉米冠层光资源利用及增产的效应,设计了玉米种子不同入土方式以及不同品种移栽入土的试验,研究了玉米生育期叶片空间布局,冠层光能时空分布特征及产量性状,结果表明使玉米叶片垂直于垄向,即胚面平行于地面且朝上,种子长轴方向垂直于垄向的种子入土方式,或使叶片伸展方向垂直于垄向的定向移栽处理可以提高生育期群体对光能的截获,达到光能优化配置在玉米群体穗位层及以上部位,促进玉米叶片光合生产,提高百粒重,玉米增产5%~9%。

摘  要：
In order to clarify the yield increase effect of oriented planting pattern, experimental treatments ofdifferent oriented initial seeds in sowing season with two varieties of maize were carried out in this study. Moreover,comparative tests of oriented transplanting and random transplanting pattern were arranged in the followed twoyears. Leaf spatial layout in the growth period, light spatial and temporal characteristics in the maize canopy struc-ture and yield characters were studied. The results indicated that leaves tended to be more perpendicular to the di-rection of row in treatment with seeds embryo plane were paralleled to the ground and upward and the long axis ofthe seed was perpendicular to the row direction. The oriented transplanting pattern of keeping the leaves perpendicu-lar to the row direction improved the light interception in the whole growth period. The light resource can be opti-mized at ear place and upper parts. Leaf photosynthetic production was promoted and 100- seed weight was in-creased. Finally, oriented planting pattern improved the maize yield by 5% to 9%.
