摘　　要：水稻产量与栽培密度密切相关,在直播、抛秧和机插秧等有别于传统手插秧的新型栽培模式下,高密度栽培更加便于农业的高效生产。本文简述了水稻不同栽培密度与产量间的关系,综述了与水稻栽培密度相关的理想株型、分蘖角度控制、分蘖数控制、直立叶、卷叶及窄叶等形态基因的研究及其进展。The yield of rice is closely related with the density of planting.Compared with traditional hand transplanting,high-density cultivation is more convenient for efficient agricultural production by the novel cultivation methods such as direct seeding,throwing rice seedlings and machine transplanting.In this paper,the relationship of planting density with grain yield was briefly summarized,and the research progress on plant morphological genes related to planting density,i.e.ideal plant architecture,tiller controlling,tiller angle,erected leaves,rolled leaves and narrow leaves were reviewed.
