摘　　要：内蒙古自治区哲里木盟科尔沁左翼后旗广泛分布着沙碱化土壤，其风沙土与盐碱土的面积占其总土壤面积的７６％，自然肥力贫瘠．但是，该旗同时分布着储量约达６２×１０６ｍ３的泥炭资源，埋藏较浅，泥炭层较厚，易于开采．研究表　明，在盐渍土种植玉米的条件下，大量增施泥炭，能获得显著的改土增产效果．Sand and saline soil was distributed widely in parts of Inner Mongolia. The area of sand soil with saline soil was about 76% of total soil area. The natural fertility of those soils was poor. However, in the same parts, about 62× 106m3 peat resources were stored in low level below ground, with thick layer of peat. The exploitation was easy. The studies showed that, with the application of peat, the yield of corn planted in the saline soil, and the fertility of the saline soil was both improved.
