摘　　要：综述了水稻株型的国内外研究现状及各构成因子包括根部、茎部、叶型及穗型性状的研究进展,指出了现阶段水稻株型研究中存在的主要问题,探讨了适宜湖南省稻区的理想株型,并提出应从株型育种和株型栽培调控等方面进行协同研究,这样才能达到形态与机能兼顾、理想株型与优势利用相结合,实现水稻超高产第三次突破。It reviewed the status quo of study on rice plant type in China and abroad,as well as the study progresses of each component factor of rice plant type,including root character,stem character,leaf type and spike type.Then,it indicated the main problems existed in study on rice plant type at present,meanwhile,it also discussed the ideal plant type for rice production area in Hunan province.Finally,it proposed that to study the plant type breeding and plant type regulating cultivation together,the goal of third breakthrough for rice super high yield can be achieved via giving a consideration to both shape and function,and combining the ideal plant type with heterosis utilization.
