Abstract

The results of irrigating patterns showed that the above-ground effective leaf area rate and highly efficient leaf area rate reached 95.36% and 81.34%,respectively,when treated with intermittent irrigation,and the flowers/effective leaf area,grains/effective leaf area,flowers/highly efficient leaf area and grains/highly efficient were high.Irrigation amount was correlated positively with leaf area index,but negatively with grains/leaf area.The differences among yield components were not significant.
