摘　　要：研究不同种植密度下，玉米单株和群体叶面积、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，即在一定的密度下保持较高的单株生产力，品种方能获得高产稳产。The changes of single plant and population leaf area dry matter accumulation and yield were nesearched in different density on maize,in order to study the interactions of single plant and population efficiency.The results show:Only to keep balance of single plant and population efficiency,that is ,to keep single plant higher productivity in suitable density,the variety will get stable and highest yield.
