采用目前生产上应用的20个籼型杂交稻品种，在高密低肥、中密中肥和低密高肥3种密肥条件下，研究了齐穗期 LAI（叶面积指数）与产量的相关性，进而分析了不同 LAI条件下产量差异、产量构成、物质积累与运转特点；同时分析了关键栽培因子与产量的相关性。最后对产量突破的途径和关键技术进行了讨论，可为目前水稻高产创建提供理论与技术参考。

In the research, 20 indica hybrid rice varieties were investigated under high-dense and low-amount, mid-dense and mid-amount and low-dense and high-amount fertilization conditions in order to explore correlation between LAI in ful heading stage with yield and to analyze yield differences, yield components, material accumulation and transferring, as wel as correlation between key cultivation factors and yield. Final y, approaches and key technology for yield breakthrough were dis-cussed, which provides theoretical and technological references for rice high yield.
