Through a 4-years field experiment， the effects of three fertilization modes，including nitrogen reduction mode(CSF)，mode of nitrogen reduction and no tillering fertilizer(CSM) and mode of broadcast-application formula fertilization by soil testing(SF)，on rice yield and its components，nitrogen use efficiency were studied and the stem tiller dynamics and variation characteristics of leaf area with high light efficiency and leaf SPAD value were analyzed，which were closely related with rice yield and nitrogen use efficiency.The results showed side deep fertilization with reducing nitrogen application by 10.6% either stabilized or increased the number of effective panicles，guaranteed yield and improved nitrogen use efficiency.During the periods of four years，the average yield of CSM treatment reached the same level with SF treatment. CSF treatment increased rice yields by 5.2% compared to SF.Moreover，CSM and CSF treatments significantly increased crop recovery of fertilizer nitrogen by 9.4 and 3.4 percentage points，respectively，compared with SF.Side deep fertilization promoted early tillering，increased the number of stems and tillers，and made the peak seedlings reached 5 days early.The peak seedlings numbers in CSM and CSF treatment were 8.4% and 12.9% higher than that in SF treatment，respectively. CSF significantly increased the top three leaves’ areas at flowering stage and increased the SPAD value of flag leaves compared with SF，which created a good material basis for photosynthetic material accumulation at later growth stage. Therefore，both the two fertilization modes can reduce nitrogen fertilizer application，meanwhile increased nitrogen use efficiency，of which CSF mode is conducive to high yield production，and CSM mode is more stable for yield production and is suitable for the situation of large planting scale and shortage of fertilization labor force.
