| 中文摘要: |
| 针对甘肃陇东旱作区年降水量少、季节分布不均，特别是玉米生产春旱严重等问题，以露地平播为对照(CK)，研究了双垄面全膜覆盖沟播，双垄面半膜覆盖沟播，宽膜覆盖平播，窄膜覆盖平播，全地面覆盖平播，膜侧播种等6种覆膜种植方式对旱作玉米出苗率、干物质积累量、株高、叶面积指数、生育时期、产量和水分利用效率的影响。结果表明，全膜双垄沟提高了玉米出苗率和出苗速度，提早成熟，整个生育期玉米株高、叶面积指数和干物质积累量始终大于其它处理，显著提高了产量和水分利用效率，是旱作区进一步挖掘降水潜力和高产田创建的有效途径。 |

| Aimed at the problems of limited and unevenly distributed rainfall and serious spring drought in the dry farming areas in east Gansu Province, the effects of six different film mulching models, including flat planting with no film mulching(CK), full film mulching on double ridges and planting in catchment furrows (FFDRF), half film mulching on double ridges and planting in catchment furrows (HFDRF), wide film mulching and flat planting (WF), narrow film mulching and flat planting (NF), full film mulching and flat planting (FF), film mulching on ridge and planting at film side (FS), on seedling emergence rate, dry matter accumulation, plant height, leaf area index, growth stages,
yield and water use efficiency of dryland maize were studied. The results showed that the mode of HFDRF could improve emergence rate and growth speed of seedlings, advance maturity time, increase plant height, leaf area index and dry matter accumulation, and raise yield and water use efficiency of maize significantly. Thus it was an effective way to exploit rainfall productive potential and to realize high yield in dry farming areas. |
