利用铁尾矿改良苏打盐碱地技术研究与应用

摘要

Compatibility tests under different conditions are conducted on the soil conditioner prepared by use of iron tailings fines, coal ashes, furfural residues, organic fermented fertilizer and ZH-1 organic ion-exchanger. The optimum ratio of all ingredients of soil conditioner is finalized. In Year 2013 to 2015, with iron tailings soil conditioner, moderate and heavy saline-alkaline land in somewhere northeast has been successfully improved, and former barren land has been turned into golden rice fields.%对利用铁尾矿粉、粉煤灰、糠醛渣性质、有机发酵肥、“ZH-1”离子置换剂制备的土壤改良剂进行了不同条件的相容性试验，确定了改良剂各种组分的最佳用量配比。2013~2015年在东北某地利用铁尾矿改良剂成功改良了中、重盐碱地，使昔日的不毛之地变成了金黄色的稻田。
