To study the effects of nitrogen fertilizer application rate on the productivity of class A green rice and utilization of fertilizers with the rate of organic nitrogen and inorganic nitrogen were 1:1, an experiment of different nitrogen fertilizer application rate was carried out in different periods. The results showed that improving nitrogen fertilizer application rate in tiller stage can increase the utilization and absorption of N-fertilizer.
