摘　　要：为探究不同种植密度对玉米干物质积累及经济性状的影响,选择聊玉20和登海鲁西2两个玉米品种,在山东省聊城市冠县进行试验。采取裂区试验设计,每个品种分别设置5种不同的种植密度,对不同品种不同种植密度下的玉米干物质积累及经济性状数据进行记录分析。试验结果表明,聊玉20和登海鲁西2这两个品种在进入抽穗期后,植株干物质积累量表现为随着种植密度增加先上升后下降的趋势,以4000株/667m2的种植密度下干物质积累量最大,实际产量以4000株/667m2的种植密度下最高。Experiment to investigate influence of different planting density on dry material accumulation and economic traits of corn was carried out in Guan county of Liaocheng city with corn varieties of Liaoyu 20 and Denhailuxi 2.The split-plot design was used for the two corn varieties with 5 different planting density,and dry material accumulation and economic traits of corn under different planting density were investigated and analyzed.The experiment results showed that dry material accumulation decreased at the beginning and then increased with increment of planting density after corn heading period for the two corn varieties,planting density of 4000/667m2 had maximal dry material accumulation and actual yield.
