| 摘 要： | 连续2年对8～9年生黄冠梨树采用不同灌溉方式和灌水量的试验,结果表明,树盘1/2区域交替灌溉较常规灌溉用水量减少2/5,其蒸腾速率显著低于常规灌溉,而水分利用效率显著高于常规灌溉,2者之间的光合速率、产量和单果重不存在显著差异。树盘1/2区域固定灌溉的水分利用效率介于2者之间,但产量和单果重与2者差异显著。

| Abstract: | Experiment was conducted with 8 to 9-year-old trees of Huangguan pear cultivar (Pyrus bretschneideri Rehd cv.Huangguan) for studying the effect of different irrigation methods and quantity on water use efficiency (WUE). Results showed that the photosynthetic rate of alternative root-zone irrigation (ARI) was similar to conventional root-zone irrigation (CRI), but its transpiration rate was dropped significantly than CRI; its WUE was significantly higher than that of CRI. There were no significant difference in fruit yield and per fruit weight between ARI and CRI, but the WUE of ARI was markedly higher than that of CRI. The WUE of fixed root-zone irrigation(FRI)was between ARI and CRI, but its fruit yield and per fruit mass were decreased significantly than ARI and CRI. |
