| 摘 要： | 交替隔沟灌溉和固定隔沟灌溉玉米的蒸腾速率较常规灌溉明显下降,光合速率有降低但降幅不大。交替隔沟灌溉玉米的叶片水分利用效率最高。随着土壤含水率的增大,不同处理玉米的光合速率和蒸腾速率都趋于增大。交替方式和固定方式玉米的光合速率增幅比常规灌溉大,叶片水分利用效率大于常规灌溉。

| Abstract: | The results showed that the transpiration rates in both of the alternate interval furrow irrigation and fixed interval furrow irrigation were both obviously decline compared with the conventional irrigation,and the photosynthetic rate also reduced but not too much.Leaf's water use efficiency is highest under the alternate interval furrow irrigation.Both of the photosynthetic rate and transpiration rate for different treatments were getting high with the soil water content increase.The range of the photosynthetic rate in alternate interval furrow irrigation and fixed interval furrow irrigation were higher than that in the conventional irrigation,and leaf's water use efficiency was also higher. |
