| Abstract: |
| 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. |
