摘要： 文章通过对大豆不同部位的去叶、去荚的处理研究表明：去下层叶片使中、上层叶片的光合作用和干物质积累均出现了较强的补偿作用，大豆去叶减源后均使单株荚数、单株粒数、百粒重下降。去荚后大豆株高有所增加，百粒重也有所增加。去荚减库后对大豆的营养生长有一定的促进作用。去中层叶和中层荚处理的产量下降最大。可见，在亚有限大豆品种中，中层叶、荚是产量的主要贡献者。

Abstract: The results of removing leaves and pods of soybean plants showed that the leaves on the midst and top greatly compensated the lost of photosynthesis and accumulation of dry matter,it was caused by the lost of low layer leaves,and it made the pods per plant,the seeds per plant and the weight per 100 seeds descend by defoliation and reducing source.The height of plant increased by removing some pods,the weight per 100 seeds did so.It improved the growth of soybean a certain extent by removing some pods and reducing the sink.And the treatments of removing the midst leaves and pods reduced the yield most,therefore,the main contributor to yield were the midst leaves and pods in sub-infinite soybean varieties.

Key words: Soybean, Source, Sink
