Abstract：Different fertilizers produce different extents of effects of ameliorating coastal saline-alkali soil. In order to select the fertilizer suitable for coastal saline-alkali soil amelioration, this study determined the effects of four types of fertilizers on the growth and development of rice seedlings grown in coastal saline-alkali soil by performing an indoor pot experiment. The experiment consisted of a control (the coastal saline soil without any fertilizer) and four fertilizer treatments as follows: compound fertilizer (A), cow dung (B), organic fertilizer (C), and marsh fertilizer (D). Compared with the control, all fertilizer treatments promoted the growth and development of rice seedlings. Of them, organic fertilizer treatment produced the most prominent plant-growth-promoting effects as follows: increases in the fresh quality and dry quality of rice seedlings by 218.18％ and 74.07％, respectively; rises in plant height and stem thickness by 107.29％ and 48.53％, respectively; increases in leaf chlorophyll and protein contents by 67.65％ and 72.74％, respectively; a reduction in the malonaldehyde content of the plant by 55.58 ％; and a rise in root system vigor by 186.05 ％.
