摘要
为了研究粉煤灰对盐碱土的改良效果,探寻新的盐碱土改良技术途径,采用田间小区试验的研究方法,研究了不同盐碱土与粉煤灰配比对植物成活率和生长量的影响。结果表明:在盐碱土壤中施入粉煤灰,可显著提高植物的成活率和生长量,在此次试验条件下,以盐碱土∶粉煤灰为1∶3和1∶2的效果较好。
In order to study the effect of fly ash on saline-alkali soil, new ways of saline-alkali soil improvement technology were explored. With the methods of field experiment, the effects of fly ash on plant survival rate and growth were studied in saline-alkali soil. The results showed that after addition of fly ash in saline-alkali soil, the plant survival rate and growth were significantly improved in the experimental conditions,the better ratios of saline-alkali soil and fly ash were 1：3 and 1 ： 2.
