Abstract：In this paper,it analyzed the effects of different Fertilizer Strategies on tiller dynamic,panicle - grain structure,nutrients uptake and fertilizer response of hybrid indica rice. Under high yield cultivation conditions,100 kilograms of rice needed N 1. 83kg to 1. 98kg. Under nitrogen - free conditions,100 kilograms of rice needed 1. 11kg with utilization rate of nitrogen is 36. 6% to 48. 0% . The optimal proportion of basic,tillering,and panicle of nitrogen fertilizer ratio were 40% ,20% and 40% . Applying revised stranford formula on hybrid indica rice to achieve fertilization with precise fixed quantity.
