摘　　要：选用直立穗型粳稻品种,对不同种植方式下的产量及其构成因素进行分析,结果表明:直立穗型粳稻品种不同种植方式的产量差异达极显著水平,行株距为23.1 cm×9.9 cm的产量最高;在产量构成因素中直立穗型粳稻品种成穗数与产量的相关性最大,相关系数为0.966 9,达到极显著水平,其次为分蘖数,相关系数为0.685 0,达显著水平。The effect of different planting motheds on yield and its compoisitions of rice with erect panicle was type analyzed. The result showed： ① the yield of rice had extreme diffirence under different planting densities and the best planting mothed was 23.1 cm × 9.9 cm; ②in the yield compositions, them was the biggest correlation between the number of panicle and yield and the correlation index reached to 0. 9669; the second was the number of tillers, the correlation index reached to 0.685 0.
