Abstract
Effects of optimized irrigation and nitrogen fertilization on the canopy structure of winter wheat were studied. The results show that compared with the sub-optimal irrigation, the optimized and traditional irrigation can elongate the length of uppermost 3 internodes of stems and increase the plant height by 10cm, decrease the flag leaf area by 8% and increase the 2nd and 3rd uppermost leaves area by 7% and 20%, respectively. The optimized irrigation decreases the angle between flag leaf and stem. Compared with the treatment without nitrogen fertilization, that with nitrogen fertilization increases all canopy structure parameters. There is little difference in the ratio of penetrated light between optimized and traditional irrigations with nitrogen fertilization. However, both of them decrease that compared with sub-optimal irrigation or the treatment without nitrogen fertilization.
