| 中文摘要: |
| 使用间作套种、普通地膜和液态地膜等措施对黄土丘陵地区的大垄沟种植方式进行了改良和优化。结果表明,普通地膜、液态地膜和间套优化措施能够提高玉米各个生育期的光合速率,提高干物质积累量。叶片生理日变化结果表明,优化措施可以明显提高玉米田间各时段光合速率、蒸腾速率,在一定程度上提高了水分利用效率。 |
| 英文摘要: |
| Inter-cropping, plastic film mulching and liquid film mulching were adopted to improve and optimize the farming practice characterized by large-size ridges and furrows in hilly loess regions. The results revealed that inter-cropping, plastic film mulching and liquid film mulching could raise photosynthetic rates, dry matter accumulation, and daily leaf physiological changes during all the periods of corn growth; in addition, the improved and optimized practice could increase the photosynthetic and transpiration rates of corn during various diurnal periods, thereby improving the water use efficiency. |
