摘　　要：本文利用三种不同粒径的吉安生物质电厂产生的灰渣对吉安当地的四种红壤样品进行了改良实验,结果有较好的改良效果,其中以细颗粒的改良效果最佳。另外,灰渣对不同土壤的改良效果是不一样的,且土壤酸度的改良效果与灰渣的用量呈正相关。生物质灰渣改良酸化土壤pH值的方法简便易行,成本较低,具有很强的实用性,值得推广。In this paper,we used the ash from the Ji'an Biomass Power Plant with three different particle sizes to improve the four local red soil samples in Ji'an,and the results showed a good improvement effect.Among them,the improvement effect of fine particles was the best.In addition,the improvement effect of different soils of ash and slag is different,and the improvement effect of soil acidity is positively correlated with the amount of ash and slag.The method for improving the pH value of acidified soil with biomass ash is simple and easy to implement,has low cost,has strong practicability,and is worthy of promotion.
