摘　　要：对小麦/玉米间作套种绿肥两粮一肥种植模式的研究表明,以小麦/玉米150 cm带幅、玉米1行麦带套种绿肥饲草的种植模式较优,平均粮食产量可达13377.0-14731.5 kg/hm^2;收获绿肥鲜草13668.0-16668.0 kg/hm^2,增加产值2996.0元/hm^2,增加效益21.10%;且培肥地力效果明显,是河西走廊“吨粮田”培肥土壤的一种有效措施。The experiments of cropping patterns fertilizers of wheat and maize were conducled. The results showed that the wheat/ maize 150 cm belt of one row maize at wheat with green manure forage grass cropping patterns was superior. The average of yield grain could reach 13377.0 - 14731.5 kg/hm^2 and green manttre fresh grasses could reach 13668.0 -16668.0 kg/hm^2. But the effect of cultivates the soft fertility was obviously, which was the one kind of effective action cultivates of soil fertilizers ＂Ton- yield- field＂ in Hexi corridor.
