摘　　要：研究结果表明:适当增加种植密度,采用优良杂交种是获得玉米高产的关键.高产田玉米具有株型与密度配合良好,适宜叶面积系数和光合势大,能保证较高的光能截获量,且库源关系协调等特征.Results of study shows that increase of the planting densities and use of the fine upright-leaf hybrids are the key to the obtainment high-yield corn. A high-yield corn field has the following characteristics: the plant-type cooperated well with its density, leaf area and leaf area index and duration are great enough to obtain more light energy and the stock relationship is coordinate.
