[Objective] Characteristics of nitrogen (N), phosphors (P) and potassium (K) uptake and their utilization of super hybrid rice were studied. [Method] Field experiments with super hybrid rice Zhunliangyou 527 and Liangyou 293 were conducted in five locations of Hunan province in 2004 and 2005. Fertilizer application rates were designed as the treatments of low rate (135 kg N·ha^-1, 29.7 kg P·ha^-1, 112.1 kg K·ha^-1), medium rate (180 kg N·ha^-1, 39.6 kg P·ha^-1, 149.4 kg K·ha^-1) and high rate ( 225 kg N·ha^-1, 49.5 kg P.ha-1, ...
