摘　　要：研究不同种植密度下油葵单株和群体叶面积、干物质积累情况及产量的变化 ,探讨单株和群体之间的相互影响。结果表明 :只有保持单株和群体之间的平衡 ,即在一定的种植密度下保持相对较高的单株生产力 。In this essay further research are make on some changes of oil sunflower.Which are caused by various densities on single plant,popuation leaf area,dry-mather accumulation and yield.We try to find out how single plant and population efficiency interact.Results indicate that only to keep the balance between single plant and population efficiency,that is,to keep the productity high on single plant under suitable density,yield of crop will get stable and high.

关 键 词：油葵 种植密度 单株效应 群体效应
