摘　　要：为探索单株与双株的不同株行距对玉米产量及经济效益的影响,以中单808为试验材料,开展了试验。结果表明:单株种植单产均高于双株种植方式,但双株种植能节约投工2.96个/667m2,减少生产投入177.6元/667m2。净产值来看等行单株移栽最高,达1 283.53元/667m2,其次为宽窄行双株移栽。In order to explore the effect of different row-spacing with single seedling and double seedlings on yield and economic beneftis of maize,taking Zhongdan 808 as test materials,single seedling transplanted and double seedlings transplanted was tested.The results showed that yield of single seedling transplanted was higher than double seedlings transplanted,but labor cost od double seedlings transplanted was saved 2.96workday/667m^2,saved costs 177.6Yuan/667m^2.Regard the net benefits,single seedling transplanted with same row spacing was the greatest,it＇s 1283.53Yuan/667m^2,double seedlings transplanted with wide-narrow spacing was the second.
