改良物质对盐碱土pH值及水溶性盐的影响

摘要

Taking Daqing salinized area as the study area,effects of five soil ameliorants (chicken manure,sludge,fly ash,phosphogypsum, distiller′s grain)on salinized soil pH value and hydrolyte-salt were studied.The results showed that distiller′s grain had the best effect on pH value and phosphogypsum had the best effect on hydrolyte-salt.%以黑龙江省大庆盐碱土地区为研究区域，研究5种盐碱土改良物质（鸡粪、污泥、煤渣、磷石膏和酒糟）对盐碱土pH值及水溶性盐的影响，结果表明：施用酒糟对盐碱土壤pH值改善效果最好，施用磷石膏对盐碱土壤水溶性盐改善效果最好。
