摘　　要：在冀南平原生态条件下,通过大田试验,研究了不同种植密度对郑单958玉米生理特性和产量的影响。结果表明,随着种植密度增加,玉米果穗叶的叶绿素含量(Chl)、光合速率(Pn)、可溶性蛋白含量下降幅度增大,实测产量以6.5株/m2密度下的产量最高。Influence of different plant density on physiological properties and yield of maize was studied by field experiment under the ecological conditions of the Southern Hebei.The results showed that chlorophyll content,photosynthesis rate and soluble protein content greatly decreased as plant density increased. The yield at 6.5 plant/m^2 was the highest.
