本文利用粉煤灰进行碱性土壤改良试验,在一定的时间、温度、土水比、粉煤灰的施加比例下,研究了碱性土壤与粉煤灰混合后土壤中水溶性CO_3~(2-)和HCO_3~-的含量变化。结果表明,使用粉煤灰可减少土壤中的碱性物质含量,当时间、温度、土水比、粉煤灰占土壤总量分别为60min、20℃、1:1、20%时,达到最佳改良效果。
In this paper, alkaline soil was modified with fly ash to study the effect of water-soluble CO_3 ~ (2) on the soil after mixed with alkaline soil and fly ash in a certain proportion of time, temperature, -) and HCO_3 ~ - content changes. The results showed that the use of fly ash can reduce the alkaline content of soil, when the time, temperature, soil water ratio, fly ash accounted for the total soil were 60min, 20 ℃, 1: 1, 20% Good improvement effect.
