摘　　要：在高密度和不同种植方式下对3个玉米品种的穗部性状及产量进行了比较分析。结果表明,穴三株种植方式有利于玉米穗部性状发育和产量提高。登海601综合表现优良。以穴三株方式种植登海601,产量较其他处理显著提高,达21031.47kg/hm2。Ear traits and yield of three maize cultivars in different cultivation methods were analyzed.The results showed that three plants per hole method had great effect on ear traits and yield of maize.DH601 was the best cultivar among three maize cultivars.there was obvious interact effect between cultivation methods and maize cultivars.The grain yield of DH601 were higher in three plants per hole method, which were 21 031.47 kg/hm^2.
