| 摘 要： | 为探明调亏灌溉对温室梨枣品质的影响，2005－2007年以日光温室7年生矮化密植梨枣树为试材进行试验，试验期间设置充分供水处理（即对照T1），萌芽展叶期（Ⅰ期）轻度或中度亏水处理（T2），及开花座果期（Ⅱ期）、果实膨大期（Ⅲ期）和果实成熟期（Ⅳ期）中度亏水处理（即T3、T4和T5）。结果表明：不同生育期亏水处理对梨枣品质的影响差异明显；与对照相比，3 a间Ⅰ期、Ⅱ期亏水处理对梨枣单果质量、含水率影响较小（P＞0.05），梨枣硬度提高13.7%～15.8%，有机酸、坏果率分别下降14.2%～18.8%和21.0%～25.0%，且均达显著水平（P＜0.05），可溶性固形物、糖酸比分别提高22.1%～24.4%和47.8%～60.0%，达极显著水平（P＜0.01），同时使成熟期提前10～12 d；Ⅲ期亏水处理使梨枣果实硬度、着色度、Vc、可溶性固形物及糖酸比依次提高22.3%、41.9%、27.0%、38.1%和53.5%，Ⅳ期亏水处理依次提高22.7%、42.3%、37.4%、27.1%和98.7%，两期均达极显著水平（P＜0.01），Ⅲ期、Ⅳ期亏水处理使有机酸显著降低（P＜0.05），并大幅降低坏果率（P＜0.01），成熟期提前15～20 d，但同时使单果质量、果实含水率降低，且Ⅲ期亏水处理差异显著（P＜0.05）；各生育期亏水处理对梨枣品质的改善程度依次为：Ⅳ期＞Ⅲ期＞Ⅱ期≈Ⅰ期。综合考虑亏水处理对梨枣品质各项指标影响，果实成熟期中度亏水处理对品质改善效果最佳，具有重要推广价值。 |

| Abstract: | In order to investigate the effects of regulated deficit irrigation(RDI)on pear-jujube quality,seven-year-old pear-jujube trees in greenhouse were studied during 2005-2007.The experimental treatments included the sufficient water supply during the whole growing period(T1),low and moderate water deficits at the bud burst to leafing stage(T2),moderate water deficits at flowering to fruit set stage,fruit growth and fruit maturation stages(T3,T4,T5),respectively.The results indicated that the different deficit ... |
