摘 要 ：与传统平作相比，垄作栽培使小麦植株的基部节间缩短，株高显著降低；旗叶和倒2叶叶面积变小，而倒5叶叶面积变大，有利于构建“松塔型”理想株型；株型构成指数改善，有利于优化叶片的空间分布；冠层绿叶干重明显增加；穗粒数增加、千粒重提高，显著增产。

Abstract:

Compared with conventional flat planting, plant morphological characters related to grain yield of winter wheat changed greatly by the raised bed planting model. The basal internodes and plant height were shorten, the areas of flag leaf and the second leaf from the top were smaller and the fifth leaves from the top larger being conductive to build up ideal pageda-shape plant, the dry weight of green leaves in canopy was heavier and grain yield increased.
