【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/hm2;收获绿肥鲜草13668.0~16668.0 kg/hm2,增加产值2996.0元/hm2,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。更多还原

【Abstract】 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/hm2 and green manure fresh grasses could reach 13668.0～16668.0 kg/hm2.But the effect of cultivates the soil fertility was obviously,which was the one kind of effective action cultivates of soil fertilizers "Ton-yield-field" in Hexi corridor.更多还原
