Abstract: Yanfeng47 was used as material, using plot contrast test method，were stuided effects of different rate of nitrogen base-tillerand panicle fertilizer on growth and yield of machine-transplanted rice were studied. The results showed that increasing the rate of base-tillerand fertilizer could increase the tiller number of rice tillering peak, rate of effective leaf area on full heading and dry matter accumulation; increasing the rate of panicle fertilizer could increase spike rate of tiller, rate of highly effective leaf area and net photosynthetic rate of full heading time, dry matter accumulation after full heading time. The effective panicle number and spikelet numbers per unit area, harvest index first increased and then decreased with the increase of rate of panicle fertilizer. The highest yield was 762.1 kg per 667 m2 when the treatment of nitrogen rate was 18 kg per 667 m2, and the rate of nitrogen base-tillerand and panicle fertilize was 20:50:30.
