摘　　要：种植密度影响着玉米群体内小气候,进而影响玉米的生长发育。在自交系及组合选育过程中,通过提高种植密度增加个体间竞争压力,可以提高自交系及组合的选择效果。介绍了密植型自交系及组合的选育鉴定方法和效果,并提出了种植和推广密植型玉米自交系及品种的配套栽培技术以及面临的难题。加快密植型玉米自交系及组合的选育进程,大力种植和推广密植型玉米自交系及品种,并辅以配套栽培技术,必将大大推动山西省玉米科研和生产水平的进一步提高,加快山西省玉米生产发展。The density of planting can influence the microclimate of maize group and their growth further. In the course of selecting maize in- bred lines and varieties, increasing the density of cultivation can enhance the competition between individuals, thus, the efficiency of selecting can be advanced. The paper introduced the breeding methods and effect of high density tolerant maize inbred lines and cultivars. The issues for the related cultivation techniques and problem were also proposed. The paper indicated that accelerating the breeding procedure, promotion and utilization of high density tolerant maize inbred lines and cultivars would promote the level of maize research and production in Shanxi Province.
