| 摘 要： | 对小麦机械收获后残茬覆盖与不覆盖 2种条件下免耕、翻耕和间隔深松 3种土壤耕作方式夏玉米的营养生长及籽粒产量进行了研究。结果表明 ,残茬覆盖和深松耕作玉米播种后出苗率高 ,次生根多 ,株高增加而基部节间缩短 ,叶面积系数提高 ,最终产量显著高于其他处理。 |
| 关 键 词： | 残茬覆盖 耕作方式 夏玉米 营养生长 籽粒产量 |

| Abstract: | The growth and grain yield of summer maize in three kinds of tillage management of no tillage, moldboard plowing and subsoiling were studied under two conditions of stubble mulch and no mulch.The results showed that in stubble mulch and subsoiling treatments the rate of emergence of maize is higher,the second root is more and the plant is higher,while the basal internode of maize is shorter.So the leaf area index and the grain yield finally can be increased. |
| Keywords: | Stubble mulch Tillage management Summer maize Vegetation growth Grain yield |
