摘要
在冀南平原生态条件下 ,通过大田实验 ,研究了不同种植密度对掖单 19玉米生理特性和产量的影响。结果表明 :随着种植密度增加 ,玉米花后果穗叶片的叶绿素含量 (Chl)、光合速率 (Pn)、可溶性蛋白含量下降幅度增大 ,实测产量结果 ,以 6 0株 m2
Influence of different plant density on physiological properties and yield of maize was studied by field experiment under south Hebei ecological conditions. The study shows that chlorophy content, photosynthesis rate and soluble protein content greatly decreased as plant density increased and processed 3 yielded the highest.
