Effects of different amount of controlled-release fertilizer（N-P-K=28-5-8） on the dry matter accumulation and grain yield of rice were studied in this paper. The results showed that the dry matter accumulation and yield increased first and then decreased after heading with increasing amounts of controlled-release fertilization. The yield of indica rice was highest（12.20 t/hm2） when the application of controlled-release fertilizer is 600 kg/hm2, with yield increasement of 5.89 t/hm2, the maximum dry matter accumulation after heading was 595.36 g/m2, and fertilizer contribution rate was 48.23% compared to no fertilizer treatment. The yield of japonica rice was highest（9.33 t/hm2） when the application of controlled-release fertilization is 750 kg/hm2, with yield increasement of 2.33 t/hm2, the maximum dry matter accumulation after heading was 566.62 g/m2, and fertilizer contribution rate was 25.00%, compared to no fertilizer treatment. The controlled-release fertilization amount more than 600 kg/hm2, the dry matter accumulation and grain yield of indica rice decreased. The controlled-release fertilization amount more than 750 kg/hm2, the dry matter accumulation and grain yield of japonica rice decreased.
