对春播和秋播矮生长豇豆的生长动态，叶面积形成与效能，结荚与豆荚产量形成特性等进行研究，结果表明，春播矮生长豇豆植株和各个器官的生长动态均呈Ｓ形曲线变化。秋播矮生长豇豆虽然无抽蔓期，但其生长动态与春播基本相同，而且植株生长和叶面积都较大，单株结荚稍多，但产量无明显差异。净同化率（ＮＡＲ）在营养生长过程较高，生殖生长过程较低。本文还讨论了矮生与蔓生长豇豆生育与产量形成的差异。
The growth dynamics, leaf area formation and efficiency, yield formation characteristics of pod and pods of spring and sowed short-growing cowpea were studied. The results showed that the growth dynamics of spring-sowed short-growing cowpea plants and various organs showed a S-shaped curve. Although there was no shortened flowering period in autumn-sowed short-bred cowpea, its growth dynamics were basically the same as in spring sowing, and the growth and leaf area of the plant were larger with a little more pods but no significant difference in yield. Net assimilation rate (NAR) is higher in vegetative growth and lower in reproductive growth. This article also discusses the differences between the growth and the yield of cowpea in dwarf and vines.
