摘　　要：盐碱化土壤是一类特殊类型的土地资源,将其改良具有保护生态环境、发展农村经济双重效益。利用各行业产生的富含有机质及氮磷钾等植物营养要素的生物废弃物可对盐碱地进行改良,在保证改良效果的同时,可降低改良成本。应用于盐碱地改良的生物废弃物主要有秸秆、沼渣沼液、剩余污泥等废弃物。概述了这3类生物废弃物在盐碱地改良中的应用现状,指出存在的问题,探讨深入研究的侧重点。Saline soil is a special type of a class of land resources,and the improvement of saline soil has double benefit to the protection of the ecological environment and the development of rural economy. Saline soil can be improved by using all kinds biological waste. In these biological waste,the content of organic matter and nutrients N/P/K was very rich. When using this improvement method,the costs were lower and the improvement effect was ensured. Straw,biogas residue,biogas,sludge and other biological waste can be applied in the saline soil improvement. This paper mainly summarized research progress on saline soil improvement of using these three types of biological waste.
