摘　　要：通过挖掘作物的生物学潜力,而非过分依赖水肥的大量投入,是实现作物产量和资源利用效率协同提高(高产高效)的重要途径。水稻产量主要来自抽穗后的光合作用,因此要实现水稻的高产高效,提高冠层光能利用率(RUE)具有重要意义。本文综述了水稻高产高效的叶面积和冠层光能利用特征以及物质积累与运转特点,分析了目前存在的问题和对未来研究的展望。By exploring the biological potential of crops,rather than relying too much on large amounts of input of water and fertilizer,it is an important way to realize the synergistic improvement of crop yield and resource utilization efficiency(high yield and high efficiency).Rice yield mainly depends on photosynthesis after heading.Therefore,improving the canopy radiation utilization efficiency is of great significance to achieve high yield and high efficiency of rice.This article reviews the characteristics of leaf area,canopy light energy utilization,biomass accumulation and transport of high-yield and high-efficiency rice,and analyzes current problems and prospects for future research.
