摘　　要：合理选择土壤改良剂对开发利用盐碱地资源具有重要意义。依盐碱地土壤改良剂施用方法及原料组成,筛选出市面上有代表性的6种改良剂产品,在新疆玛纳斯盐碱地上,进行了土壤改良剂对棉花生育期土壤盐分、pH以及棉花产量的影响试验。结果表明:按施用方法比较,滴施型土壤改良剂降低棉花生育期土壤盐分、pH值以及提高棉花产量效果均极显著优于基施型土壤改良剂;按原料组成比较,以黄腐酸等低分子量、水溶性有机酸为主要组成成分的土壤改良剂效果较优。It is of great significance to choose reasonable soil amendment for develop and utilize saline - alkali land resources, Six kinds of representative saline - alkali soil amendment products on the market were selected in accordance with the methods of application and raw materials composed of types. The experiments of different soil amendment for soil salinity, pH and yields in cotton growth periods has been done in Manas saline land in Xinjiang. The results showed that compared with the application methods the drop appling method was better than the basic application of the soil amendment. The effect of soil amendment with low molecular weight, water - sol- uble organic acids, like the fulvic acid, as main composition is the best.
