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%.
