| Abstract: | ZD958,XD20,XD22 and DH3719 were taken as materials to study the population canopy structure and light energy utilization of high yield maize hybrids under the high-yield planting condition in a field experiment.The results indicated that the four high yield maize hybrids had high LAI,small leaf angel of upper leaves,better light conditions for the ear-leaf,high light interception rate and high net photosynthesis rate. |
