摘　　要：[目的]研究不同综合处理模式对工程扰动地玉米产量及其根际土壤理化性质的影响。[方法]以马龙县工程扰动1年土壤和玉米为研究对象和材料,研究不同处理对工程扰动土壤养分、酶及其玉米生物学性状的影响。[结果]与处理①(牛粪+全量化肥)相比,处理②(玉米秸秆还田+生物有机肥+石灰粉+地膜覆盖+80%化肥)和处理③(绿肥还田+生物有机肥+石灰粉+地膜覆盖+80%化肥)可使土壤的团聚结构和稳定性显著增强,有机质含量和CEC显著提高,脲酶活性、过氧化氢酶活性显著增强。[结论]不同有机肥配合石灰粉、地膜覆盖措施、绿肥还田等综合技术可以明显改善云南黄红壤供肥性能。[Objective]The research aimed to study the effects of different integrated treatment models on the yield of maize in the engineering disturbed soil and the physical and chemical properties of rhizosphere soil.[Method]The Malong County engineering disturbed soil and corn for 1 year as research objects and materials,the effects of different treatments on the soil nutrients,enzymes and biological characteristics of the engineering disturbed soil were studied.[Result]Compared with treatment 1(cattle manure+full quantitative fertilizer),treatment 2(corn straw returning+bio-organic fertilizer+lime powder+film cover+80%fertilizer)and treatment 3(green manure returning+bio-organic fertilizer+lime powder+film cover+80%fertilizer)could significantly enhance the aggregation structure and stability of soil,organic matter content and CEC,urease activity and catalase activity.[Conclusion]Different organic fertilizers combined with lime powder,plastic film mulching and green manure returning can significantly improve the fertilizer supply performance of Yunnan yellow red soil.
