摘　　要：试验结果表明 :杂交中籼协优 5 7群体性状及产量随着施氮量和栽插密度而异。施氮量与栽插密度两因素的交互效应大于因子简单效应之和 ,其作用极显著地影响着群体性状量的变动。处理组合的平均穗谷重、穗数和稻谷产量的变幅依次为 2 .60～ 3 .91g、2 3 0～ 3 0 1个 /m2 和 811.9～ 969.The experimental results showed:the traits of population and yield of hybrid rice Xieyou 57 varied with the different levels of nitrogenous fertilizer and planting density. The quantity of interaction effect between nitrogenous fertilizer and planting density went beyond the sum of simple effect. The traits of population were affected by the interaction effect significantly. The various range of grain weight per panicle, panicles number and rice yield in treatment combinations were 2.60～3.91g、230～301wh /m 2 and 811.9-969.0 g/ m 2.
