摘　　要：从国内外玉米生产形势上看,种植密度是提高玉米产量的重要栽培措施之一,在种植密度较高的地区,更宜种植紧凑型玉米品种来获得较高的籽粒产量。本文结合国内外学者研究结论,从群体冠层形态结构和光合生理角度,比较了紧凑型玉米品种与平展型玉米品种差异,系统阐述了紧凑型玉米品种产量提高的形态生理学基础,为紧凑型玉米品种高产高效栽培生理研究和抗逆玉米新品种选育提供理论指导。Planting density is one of the important cultural practices to improving maize yield from maize pro- duction situation at home and abroad. In higher planting density areas, more appropriate planting compact maize varieties to getting higher seed yield. The differences between compact maize varieties and setting-out type maize varieties were conducted from population canopy shape structure and photosynthetic physiology, combined with domestic and overseas scholars research conclusion. This review introduced the morphophysio- logical basis of increasing compact maize varieties yield, which provided theoretical guidance for high yield and high efficiency cultivation physiological research of compact maize varieties and new adversity resistance breeding of maize varieties.
