| 摘 要： | 对南疆复播杂交玉米901品种7种密度下穗部性状和产量构成因素和群体叶面积动态的研究结果表明：①随着密度的增加，穗长、穗粒数和千粒重有减小的趋势，达最大LAI时期前移；②密度对单株穗粒数影响最大，其次是千粒重；③拟提出南疆高产复播玉米群体有关生产指标。

| Abstract: | We have investigated the characters of ear,the change of leaf area in group maize and variety of the dry matter accumulation in one maize among seven planting densities to the hybrid maize No901.The result showed: the length of ear,the corn granule,the weight of thousand granules would gradual descend with improving the plant density and the period of biggest LAI becomes earlier in high density;the density seriously affects the corn granule,then affects the weight of thousand granules;draw up some factors about the high producing maize in south of Xing jiang. |
