摘　　要：松嫩平原是北方春玉米带的主要分布区,当前主要存在3种主要玉米种植模式,分别是均匀垄种植模式、大垄双行覆膜种植模式和膜下滴灌水肥一体化种植模式。在构建评价指标体系基础上,以乾安县为例,运用可拓优度评价法对3种玉米种植模式进行评价。结果表明,在乾安县现有的3种玉米种植模式中,从节本增效效果看,膜下滴灌水肥一体化种植模式优于大垄双行覆膜种植模式,大垄双行覆膜种植模式优于均匀垄种植模式。膜下滴灌水肥一体化模式在推进玉米节本增效方面具有显著比较优势,综合效益尤其是生态效益凸显,可加大推广力度,促进松嫩平原玉米种植模式转型升级。Songnen Plain in North China is the main distribution area of spring corn belt, where there are threemain corn planting patterns, including planting on uniform ridge, planting on double row film mulching in a largeridge and integrated planting of water and fertilizer under drip irrigation under the film, which are evaluated by us-ing the extension preference evaluation method on the basis of constructing the evaluation index system in Qian＇anCounty. The results showed that the integrated planting of water and fertilizer under drip irrigation under the filmwas superior to that of the planting on double row film mulching in a large ridge, and the planting on double row filmmulching in a large ridge was superior to that of the planting on uniform ridge basis on the effect of economizing oncost and increasing efficiency. In particular, integrated planting of water and fertilizer under drip irrigation underthe film, its comprehensive benefits, especially the ecological benefits, should be highlighted. It is necessary to in-crease the promotion and promote the transformation and upgrading of the corn planting in the Songnen Plain.
