In order to clarify the effects of acid rain on carbon (C), nitrogen (N), phosphorus (P) contents and ecological stoichiometry of riceleaves, we set the control (CK), pH4.5 and pH3.5 acid rain treatments. C, N and P contents and their ecological stoichiometry were measured and analyzed in different rice growth stages in the paddy field of Fuzhou rice fields along the river. The results showed that the carbon, nitrogen and phosphorus contents in early rice leaves were 401.08±1.83 g/kg, 37.01±2.54 g/kg, 1.01±0.05 g/kg during rice jointing stage and 349.08±4.52 g/kg, 15.52±0.05 g/kg, 0.48±0.01 g/kg during maturity stage. The carbon, nitrogen and phosphorus contents in late rice leaves were 389.00±2.82 g/kg, 28.52±0.31 g/kg, 0.74±0.01 g/kg during rice jointing stage and 317.25±1.65 g/kg, 8.18±0.51 g/kg, 0.29±0.03 g/kg during maturity stage. The nutrient content of early rice leaves was higher than that of the late rice (P<0.05), and the nutrient content in the jointing stage was higher than that in the mature stage (P<0.05). On the whole, the carbon, nitrogen and phosphorus contents of early rice leaves were decreased by the acid rain treatment during the jointing stage (P<0.05). The C/N, C/P, and N/P ratios in early rice leaves were 10.94±0.77, 400.13±18.91, 36.77±2.07 during rice jointing stage, and 23.19±0.63, 737.04±30.47, 32.08±1.03 during the maturity stage. The C/N, C/P, and N/P ratios in late rice leaves were 13.74±0.26, 528.10±0.26, 38.70±0.74 during rice jointing stage, and 39.61±2.11, 1148.97±103.82, 28.90±1.27 during the maturity stage. On the whole, the ratio of late rice leaves were higher than that of the early rice. According to the N/P ratio among treatments, the status of rice phosphorus limitation was not changed. It is necessary to apply proper amount of phosphate fertilizer in rice growth, especially during the jointing stage.
