Objective] To discuss the characteristics and economic characters of major cultivated maize varieties in Mouding County of Yunnan Province.[Method] In maize main production areas, biodegradable mulch cultivation technique with high density and single factor was adopted. The growing characters, agronomic characters and economic characters of 29 varieties on display were analyzed.[ Result] Xianyu 508 had the highest yield (99 89.70 kg/hm2), followed with Luyu 6 (9 775.65 kg/hm2).Luyu 6, Mingyu 9011, Chengdan 22, Zhengda 666, Caijia 8, Zhengxing 508, Eyu 16, Liaodan 308, Zhonghe 606, Xinyu 968 had relatively good agronomic characters, stress resistance, adaptation and yielding ability, which could be planted in medium altitude area.Zhongyunshi 5, Sanxiayu 9 and Ningyu 721 were not suitable to be planted in Mouding Area due to the occurrence of grey speck disease.[ Conclusion] Maize planting in Mouding Area should adopt high-density planting, early sowing in good time, and applying slow-release fertilizer.Application of biodegradable mulch cultivation technique can enhance the compre-hensive benefit of maize planting.%[目的]探明云南省牟定县主要栽培玉米品种的特征特性及经济性状。[方法]在玉米主产区采取单因素、高密度配合生物降解地膜配套栽培技术，对展示的29个主栽玉米品种进行生育性状、农艺性状、经济性状分析。[结果]先玉508产量最高，为9989．70 kg／hm2，潞玉6号产量次之，为9775．65 kg／hm2；潞玉6号、明玉9011、成单22、正大666、彩稼8号、振兴508、鄂玉16号、辽单308、中禾606、鑫玉968等品种农艺性状、抗逆性、适应性、丰产性在参展品种中均表现较好，可在中海拔区域大力推广种植；中云试5号、三峡玉9号、宁玉721这3个品种因后期灰斑病发生危害严重，不适宜在牟定地区推广种植。[结论]当地玉米种植应推广高密植栽培，适时早播并配合施用高效玉米缓释肥，结合应用生物降解地膜栽培可提高玉米种植综合效益。
