1. The result showed the cultivating pattern (SHCDNR) had higher LAI of population, longer period of functional leaf and higher relative light intensity in the canopy, compared with traditional sowing in hole with broad drill and wide ridge.
结果表明：与传统的宽畦宽行穴播相比，窄畦窄行穴播大豆群体LAI高，叶片功能期长，相对光强高；
2. The comprehensive seeding accuracy testing method proposed in this dissertation to test performance of precision seeder, grain drill seeder, hill-drop planter, seeding monomer, and seed sowing device is an integrative one with technology of computer vision, patter recognition, and automatic control.
本文提出的适用于精密播种机、谷物条播机、穴播机，及排种器等多类型播种机具的播种精度检测方法，是集计算机视觉、模式识别、自动控制为一体的综合技术。
