水分处理对生长高峰期株高和分枝长度的相对生长率没有显著作用，高施肥量则加大了其相对生长率。

Higher fertilization promoted the relative height and length growth rates of the branches, but watering treatments hadn't significant effects on them.

通过对生育期、株高、分枝数、主茎节数、单株荚数、百粒重等性状的相关分析和灰色关联度分析，结果表明，分枝数、单株荚数是影响产量的关键因素。

Comparative analysis and grey correlation degree were carried on soybean traits, the results were as follows: branch number and pods per plant have more important effect on yields.
