【摘要】 采用起垄、覆膜、露地平栽 3种栽培模式 ,探索起垄种植对冬小麦的增产潜力。试验结果表明 ,起垄种植较对照露地平栽增产 30 .9% ,比覆膜种植增产 36 .7% ,起垄种植模式下株型结构、根冠比合理 ,为根系生长提供了较大的根际 ,为小麦获得较高产量奠定了良好的基础更多还原

【Abstract】 Three winter wheat cultivation techniques of ridged planting,plastic film mulching and non landed cultivation were applied to study potentiality of yield increase of winter wheat.The result showed that the ridge’s model increases 30.9 percent than the mulching cultivation,increased 36.7 percent than covered plastic film’s mulching.Model of ridging the shape of plant and root/crown are rational,which provided larger space for roots system,has a solid foundation for high yield in winter wheat.更多还原
