| Abstract: |
| The paper utilized experiment data of three years to analyze meteorological condition, yield character, water utilization efficiency(WUE) and reactivity coefficient between moisture and yield in the whole growth stage of summer corn.It was found that the different growth stage on summer corn yield was different;the affection of water stress in tasseling stage was the largest,in which the reactivity coefficient between moisture and yield reaches 1.443.This stage is the key period for irrigation and increasing yield. |
