| 中文摘要: |
| 选用垄膜覆盖沟播、全膜双垄沟播、全膜平铺穴播、全膜平铺沟播等4种地膜覆盖方式，研究了不同地膜覆盖种植方式对谷子光合作用、生长速
度及其产量的影响。结果表明，地膜覆盖种植提高了谷子生长期间的净光合速率和水分利用
效率，在抽穗期，地膜覆盖种植方式的光合速率比露地种植的高9.8%～28.5%，水分利用效
率比露地的提高3.0%～18.1%；同时，地膜覆盖种植明显加快了谷子生育期间的生长速度，
在苗期至成熟期，地膜覆盖种植方式的平均生长速度较露地快28.7%～35.5%。地膜覆盖种植
方式增产显著，产量在3 429.00～4 233.60 kg·hm-2之间，比露地沟播种植方式增
产30.87%～61.57%。 |

| The experiment was conducted to investigate the effects of different film mulching and planting patterns on photosynthesis, growth rate and yield of millet by adopting 5 treatments, i.e., flat planting and no plastic film mulching (NM), ridge film mulching and furrow seeding (RFFS), full plastic film mulching and furrow seeding (FFFS), full plastic film mulching and bunch planting (FFBP), and full plastic film mulching on double ridges and planting in catchment furrows (FFDRF). The results showed that, the film mulching patterns improved the net photosynthetic rate and water use efficiency during the growth period of millet. At heading stage, the photosynthetic rate and water use efficiency of millet under film mulching patterns were increased by 9.8%～28.5% and 3.0%～18.1% respectively compared to those of no mulching. The film mulching patterns also significantly accelerated the growth rate during the growing period of millet. From the seedling to maturity stage, the average growth rate of millet under film mulching patterns was 28.7%～35.5% faster than that of no mulching. The film mulching patterns could significantly increase the yield of millet, which was 3 429.00～4 233.60 kg·hm-2, being 30.87%～61.57% higher compared with no mulching. |
