摘 要 ：1983—1984年,通过群体水培、土培试验,在控制水稻根系不同分布空间形状情况下,研究了叶角与根系分布的关系,其结果主要表现如下:1.根系分布较深且多纵向时,叶角较小,叶片趋向于直立;根系分布较浅且少纵向时,叶角较大,叶片趋向于披垂。2.叶角的大小同时受叶片大小的影响,根系分布较浅且少纵向时,较大的叶片更易披垂,叶角更大,

Abstract:In 1983-1984,the relationship between leaf angle and root distribution was investi-gated in rice cultivated in nutrient solution and soil.The different root systems were estab-lished by controlling the root distribution space.The results were as follows:1.The deeper the root distribution,with vertic
