本文就夏玉米“农大54”观察了营养器官及生殖器官的具体表现,以及施用追肥对这些器官的影响,分组剪叶对这些器官的影响,叶片光、毛的区分。提出了以光、毛叶及果穗位为分界限,把叶片分为上、中、下三组,在其主要功能上,分别主攻粒、穗、根。并作了相应的比较和探讨。

In this paper, on the summer corn “Nongda 54 ” observed the specific performance of vegetative organs and reproductive organs, as well as the application of top dressing on these organs, the effect of grouping leaves on these organs, leaf light, hair distinction. Proposed to the light, leaves and tassel bit as the limit, the leaves into the upper, middle and lower three groups, in its main function, respectively, the main grain, spike, root. And made the corresponding comparison and discussion.
