摘　　要：为了明确晚熟玉米新品种丹玉405、丹玉206在辽东南地区的最佳种植密度，在辽东南3个地点（凤城、海城、瓦房店）进行了连续2年的密度试验，每个试验点设置5个密度梯度。试验结果表明：丹玉405适宜种植密度为36000～45000株/hm^2，丹玉206为48000～52500株／hm^2。For determining the best planting density of two new late-maturing maize varieties Danyu 405 and Danyu 206 in southeast of Liaoning province, exerting their production potential, and then getting the highest yield, this density experiment was conducted for two conseetutive years in three regimes of Fengcheng, Haicheng and Wafangdian, which was designed five different densities in each regime. The results provide theoretical basis for local maize safe production.
