摘　　要：以通禾833和通禾838为试材,研究不同氮素水平下株行距配置对吉林稻区水稻生长发育、光合及物质生产能力的影响。结果表明,株行距配置式对水稻各阶段株高影响不明显;株行距配置(A)(22.3 cm×22.3 cm)群体条件下水稻叶龄进程加快,有利于促进水稻生育进程和籽粒充实;株行距配置(A)在促进水稻分蘖和增加有效分蘖数上具有一定优势;同时,株行距配置(A)有利于叶面积指数、叶片光合速率、物质生产能力及稻谷产量的提高,分蘖数的增加和光合速率增强是株行距配置(A)物质生产能力和稻谷产量提升的主因。With japonica rice TongHe 833 and TongHe 838 as test materials, effects of row-spacing on growth and development, photosynthetic ratio and matter production of rice under different nitrogen application levels were studied. The effect of row-spacing on plant height was insignificant. The leaf age progress of row-spacing treatment A （22.3 cm×22.3 cm） was accelerated, that help facilitate the development of growing development and grain filling. The row-spacing treatment A had remarkable advantages on improve rice tillering and effective tillering. Furthermore the row-spacing treatment A also benefited to increase of leaf area index, photosynthetic rate, matter production and grain yield in Jilin Province. The increase of the number of tillers and photosynthetic rate were the main reason.
