The effect of different proportion of base-tiller N fertilizer and panicle N fertilizer on growth and yield of rice in coastal saline alkali land by the plot comparative test was studied in this paper, with Yanjing 456 as material. The results indicated that postpone nitrogen fertilizer could coordinated the rice population, controll tillers in the peak tillering stage, increase the rate of tillers to panicle and glumous flower per unit. It can promote the leaf area index (LAI) and high-efficiency leaf area rate of full heading stage, the dry matter accumulation in mature stage, and the rate of dry matter accumulation after heading to the yield. The treatment with base-tiller N fertilizer and panicle N fertilizer of 6∶4 reached the highest yield of 788.2 kg/ 667 m2.
