In order to ascertain the effects of postponing and decreasing nitrogen application on nitrogen use regula-tion and transportation character of super rice‘Jijing 88’, field experiments with different treatments were conduct-ed in the study to investigate the effects of postponing nitrogen application on nitrogen use efficiency and yield of su-per rice‘Jijing 88’. The results showed that yield was increased by-0.78%~7.5% by postponing and decreasing ni-trogen application. It was indicated that total nitrogen absorption and accumulation of super-rice‘Jijing 88’atmid- to late stage increased by properly postponed and cut down nitrogen application, nitrogen translocation rate instem, sheath and leaf decreased, so the nitrogen use efficiency, agronomic efficiency and partial factor productivitywere raised. All the influence factors considered, the best nitrogen fertilizer use efficiency were obtained by applying141.31 kg/hm² and topdressing and earring fertilizer applied 13 d and 9 d later. The highest yield was 11 t/hm².
