摘　　要：作者分析研究了目前山东省3种不同株型玉米杂交种的主要农艺性状,认为紧凑型玉米杂交种的产量最高,中间型玉米杂交种次之,平展型玉米杂交种的产量最低。紧凑型玉米杂交种高产的主要原因是由于增大密度使总粒数增多。因此,今后应大力选育和推广紧凑型玉米杂交种,以提高玉米产量。This paper focuses on the main agronomic traits of three different maize hybrids in Shandong province. It showed that compact-hybrid is most productive, due to its high density and more grains per hectare, as well as the high 1000-seed weight, then the medium-hybrid and the fiat-hybrid have the lowest production. So it＇s recommended to select breeds and extend compact-hybrid to increase the production.
