Abstract: The application of nitrogen fertilizer according to the growth characteristics and nitrogen requirement of rice has important significance to reduce rice nitrogen fertilizer, nitrogen loss, improve economic efficiency and protect the environment. A field experi-ment was conducted to study the effects of different nitrogen application rates on rice yield and nitrogen uptake, using hybrid indica rice Zhongzheyou 1 and conventional japonica rice Nangeng 5055 as materials. The results showed that there was a significant differ-ence in the nitrogen demand between the two types of rice. Among them, the yield of Nangeng 5055 under the condition of 225 kg N/ hm2 was higher than that of 180 kg N/hm2 significantly, while Zhongzheyou 1 was opposite. The ratio of nitrogen application also had a significant effect on rice yield. The increase of the proportion of panicle fertilizer promoted the growth of rice shoot, nitrogen uptake and yield of two kinds of rice. The above results showed that the optimum nitrogen application of rice should be adjusted according to the variety, and higher nitrogen application ratio at panicle stage would be beneficial to the increase of yield.

Key words: rice; nitrogen application rate; nitrogen application ratio; yield
