摘　　要：叶片作为水稻器官建成的物质基础,与水稻群体中光环境的优劣和光能利用率的高低关系密切。而叶面积指数(LAI)的大小直接与水稻最终产量相关,且水稻冠层中光合有效辐射吸收系数与叶面积指数相关性极显著。文章综述了水稻在生长的各个阶段叶面积指数和产量之间的关系,同时通过优化品种、改善栽培措施等手段增加水稻最适叶面积指数,提高水稻产量,以期为高产水稻适宜叶面积指数的预测及合理冠层结构的调控提供理论依据。Leaf,as the material basis for constructing the rice organs,is closely related to the quality of the light environment and the utilization rate of light energy.The leaf area index(LAI)is an important indicator related to rice yield,and is significantly correlated with the light and effective radiation absorption coefficient in rice canopy.In this paper,we reviewed the relationship between the LAI in different growth periods of rice and the yield,and pointed out that the optimal LAI could be increased based on variety selection and cultivation measures,to achieve the high yield.The study could provide a theoretical basis for developing a predicting system of the optimal LAI and for regulating the rational canopy structure of rice.
