| 摘 要： | 研究了不同播期麦套玉米与单作玉米在生物学性状方面的差异。结果表明,共生期间,不同播期单作玉米的展开叶数、次生根数、地上部鲜重和干重均高于麦套玉米,可见叶、种子根、株高不尽一致;麦套玉米由于小麦的遮阴,比同期播种的单作玉米生育期推迟,叶片总数、果穗叶位减少,穗位高、株高降低。麦套玉米适时套种时间应在小麦收获时,玉米苗在3叶展开期前后(在山东省玉米品种郑单958适宜套种时间为5月21～26日),麦收后立即中耕灭茬,适时追肥浇水,加强田间管理,能够达到单作玉米的产量。 |

Analysis on Biological Differences of Corn under Different Cultivation methods |
|
| Abstract: | The biological difference of corn under different planting time and cultivation methods were studied. Two kinds of cultivation methods were planting corn only in one field and interplanting corn during the later period of wheat. The differences in leave number, roots number and weight, plant height, growth and development period, ear height and yield in corn were reported under two different cultivation methods. |
| Keywords: | interplanting corn with wheat planting corn only sowing time characteristics of single plant growth and development period yield |
