%X The geometrical characteristics of crop colony are described by leaf inclination and position angles.The leaf inclination angle is mainly affected by genetic characters of the crop,the planting design has little influence on it.Leaf area index is larger for the variety with larger inclination angle,and smaller for the variety with smaller inclination angle.The leaf azimuth to a great extent is decided by the planting design.
