Abstract: Super rice′yanfeng 47′was used as materials，using plot contrast test method to investigate the effects of the different ratios of nitrogen basetillerear fertilizer on development and yield of rice in coastal rice region.The results showed that the ratios of basetillerear fertilizer was 2∶5∶3 in the B treatment got 978 thm2 per unit yield，comparing with the treatment of A（2∶4∶4）、C（2∶6∶2）and D（2∶8∶0），the yield increased 06%、34% and 56%.The effective panicle number and spikelet numbers per unit area，dry matter yield，dry matter accumulation，full heading accounted for the percentage of yield and N，P uptake were all higher than the others.With the increasing proportion of panicle fertilizer was beneficial to increasing the yields and N P uptake of rice.
