摘　　要：为了改良修复盐渍、板结、贫瘠的土壤,充分资源化利用味精尾液、草木灰、废活性炭等工农业废弃物,采用浓缩喷浆造粒、物理吸附农业益生菌等技术,进行了土壤调理剂的研制和生产。经过多地连续两年的应用验证,使用土壤调理剂后,土壤的pH值降低0.62,全盐量下降0.13%,有机质增加0.86 g·kg-1,容重增加0.08 g·cm^(-3),孔隙度增加3.67%,更适宜农业种植,说明该土壤调理剂改良土壤的效果明显。In order to improve and repair the saline,hardened and barren soil,and make full use of industrial and agricultural wastes such as monosodium glutamate tail liquor,plant ash and waste activated carbon,the technology of concentrated spray granulation and physical adsorption of agricultural probiotics were used to develop and produce soil conditioner.The results showed that,after using the soil conditioner for two years,the pH value of soil decreased by 0.62,total salt content decreased by 0.13%,organic matter increased by 0.86 g·kg-1,bulk density increased by 0.08 g·cm^(-3),and porosity increased by 3.67%.So the soil conditioner has obvious effect on soil improvement.
