【摘要】 于大豆开花期对亚有限大豆品种东农 594进行 3种密度、 8种组合的人工去叶裂区设计试验 ,评价了大豆垂直方向上不同叶层面积大小对产量及主要农艺性状的影响。试验结果表明 ,在大豆生育后期 ,中层叶片对产量及农艺性状有重大影响 ,上层次之 ,下层影响甚微。根据试验结果认为 ,大豆生育后期的中层叶片是决定产量的重要层次。大豆垂直叶面积分布最合理的类型与无限型大豆相类似更多还原

【Abstract】 A semi determinate line Dong Nong 594 was used for the master slave design with three densities and eight treatments,Whose influences on yields and agronomic characters at stratified distributions of leaves on vertical were compared.The results showed that the middle layer of leaves has a tremendous influence on the yields and agronomic characters at later stage of growth.With the results of this experiment,we consider that the identical type of stratified distribution of leaves is the same as the indeterminate type of growth habit.$$$$更多还原
