摘　　要：闽糯0018群体结构试验表明:种植密度为6.0万株.hm-2时,群体叶面积发展动态合理,净同化率与叶面积系数最高,生育期内干物质积累量最大,库源比及经济系数较合理,产量及产量性状表现最优,有效调控各个时期的群体叶面积,对中后期干物质的积累以及产量的形成有重要影响。Population construction of Minnuo 0018 was stuided. The result showed that the population leaf area developing was reasonable while the planting density was 6.0×10^4·hm^-2, net assimilation rate （LAD） and leaf area index （LAI） were all the highest, dry matter accumulation was the most during the growing period, source-sink ratio and economic coefficient were more equitable, yield and yield character were best. Regulating the population leaf area at different stages has an important influence on dry matter accumulation and yield.
