摘要：

为了搞清油研九号在移栽条件的适宜播期 ,进行了油研九号不同播期的试验研究。结果表明 ,不同播期的产量间存在极显著的差异 ,获得高产的播期为 9月 4～ 11日 ;不同播期整个生长进程中的平均单株鲜重间存在极显著差异 ,并与播期间呈一元二次抛物线关系 ,平均单株鲜重和最大单株鲜重均与产量呈极显著的正相关 ;不同播期生长进程中的单株平均角果鲜重间无显著差异 ,但与播期间呈一元二次抛物线关系 ,不同播期不同时期的单株角果鲜重与生育进程间均呈开口向下的抛物线关系。

摘要：

The study result showed that the yields existed very significant difference between different seeding dates. The seeding date of abtaining high yield for Youyan 9 is september 4～11. There were very significant difference in average single plant fresh weight in the course of growth between different seeding dates, shown parabolical curves correlation between average single plant fresh weight and different seeding date. There were very positively significant correlation within the average single plant fresh weight, maximum single plant fresh weight and yield. There were no significant difference in average single plant pod weight in the course of growth between different seeding dates, and shown parabolical curves correlation between average single plant pod weight and different seeding dates. There were parabolical curves correlation between single plant pod fresh weight and the course of growth in different seeding dates.
