Because of nitrogen, the value of IAA/ABA、GA3/ABA、(IAA+GA3+ZR)/ABA in grain promoted at seed filling stage and at the mature stage.6、The adjustment of nitrogen levels on carbon and nitrogen metabolism.Nitrogen reduced the C/N in leaves and stem. When the nitrogen rate was 50 kg/hm2, the effect on stem was obvious. When the nitrogen rate was 100 kg/hm2, the effect on leaves was obvious. The C/N in roots lower before seed filling stage and the effect was not obvious after seed filling stage.7、Effect of nitrogen levels on yield traitsPlant height, pods per plant and full grain number were increased and bottom-pod height and podded node were decreased by applying nitrogen.
