| 摘 要： | 研究4种耕作方式创建的耕层构造即免耕全实耕层、翻耕全虚耕层、留茬深松虚实并存耕层、灭茬打垄上虚下实耕层对玉米生长发育的影响。结果表明，留茬深松虚实并存的耕层构造玉米植株形态优于其他3个耕层的处理，其株高和最大叶面积分别较灭茬打垄上虚下实耕层处理实提高8.37%和14.18%，气生根条数比灭茬打垄上虚下实耕层处理增加16.8条，净光合速率较灭茬打垄上虚下实耕层处理提高16.76%，4个处理在茎粗上差异不明显。留茬深松耕作方式创造的虚实并存耕层结构能够充分满足玉米生长发育的需求。

| Abstract: | The effects on the growth of maize four types of soil plough layers(no tillage whole compaction, tillage whole spacing, stubble-subsoiling compaction and spacing, stubble-breaking compaction and spacing) were studied. The result showed that, plant morphology of stubble-subsoiling treatment was better than the other three treatments. It's plant height and LAI were higher than stubble-breaking compaction and spacing treatment with 8.37% and 14.18%. Compare to stubble-breaking compaction and spacing treatment, its aerial root amount was higher with 16.8 and it's Pn was higher with 16.76%. There was no obvious difference on stem diameter in four treatments. It indicated the soil plough layer environment created by stubble-subsoiling tillage can satisfy the demand for maize growth. |
