Abstract

Through pot experiment, the paper explored the impact of saline-alkali soil ameliorated by coal ash and coal gangue on the growth tamarisk. The experimental results indicated that the amelioration effect of saline-alkali soil by adding 15 % coal ash and 15% silt was distinctly better than adding 10 % coal ash, 10 % coal gangue and 10 % silt, also better than adding 20 % coal ash. Adding coal ash to matrix had acceleration effect in enhancing sprouting rate, shortening branches’ sprouting time and improving sprouted branches’ survival rate of tamarisk. Adding different amounts of coal ash to saline-alkali soil had different amelioration effect, that was 15 %>20 %>10 %. This experiment reached the original requirements and expectations, and the analysis of acquired data was scientific and practicable, so it had reference significance.
