摘　　要：针对碳酸盐黑钙土有机质含量逐年减少,保水、保肥、蓄水保墒能力下降等问题,开展了以增施牛粪、翻压绿肥和配方施肥等方法的碳酸盐黑钙土修复技术研究.结果表明,采用增施牛粪、绿肥等有机肥和配方施肥技术可明显改善碳酸盐黑钙土的理化性质,与当地常规施肥相比,增施有机肥和配方施肥处理的田间持水量增加6.9％～17.4％,土壤孔隙度增加7.4％ ～11.8％,土壤容重降低0.09 ～0.1 g/cm3,玉米产量增加10.3％ ～ 16％,翻压绿肥对碳酸盐黑钙土保墒蓄水能力提升效果好,连续施用有机肥对退化碳酸盐黑钙土修复效果明显.According to the serious situations of soil organic content reduced year by year, and the ability of soil water preser- ving decreased, we studied the carbonate chernozems remediation technique through cow dung, green manure, and formulated fertilization. The result showed that adoption of such techniques as adding organic manure such as cow dung, green manure, and formulated fertilization could significantly improve the physical characters of the carbonate chernozems. On the basis of nor- mal fertilization in the local regions, adding organic manure and formulated fertilization increased the field water-preservation rate by 6. 9% - 17.4%, increased the soil porosity by 7.4% - 11.8%, decreased the soil volume weight by 0. 09 - 0. 1 g/cm3 and increased the corn yield by 10. 3% - 16%. The effect of green manure application was the best in improving the water preserving ability of carbonate chernozems. The effect of continuous applying organic manure to improve degenerated carbonate chernozems was significant.
