| 摘 要： | 为了探明不同灌溉方式对干旱区枣树灌溉水量分配、枣树生长和果实品质的影响,2009年以阿克苏试验林场成龄枣树为研究对象,研究了地面灌、滴灌和微喷灌3种灌溉方式下灌溉水的去向、枣树生长、产量、水分利用效率和果实品质。结果表明,与地面灌相比,滴灌及微喷灌有效地减少了田间水的深层渗漏,节水49%,而且对枣树生长影响并不显著。滴灌和微喷灌能够有效促进叶面积指数、叶绿素相对含量的提高,进而提高产量,滴灌增产22%,微喷灌增产16%;水分利用效率分别提高240%和230%;而且显著提高果实横径、单果质量、还原糖含量以及维生素C含量。由此可见,滴灌及微喷灌方式显著提高了枣树的果实品质和产量,研究成果为干旱区林果节水灌溉提供实践依据。 |

| Abstract: | In order to investigate the effects of irrigation methods on water distribution, growth and fruit quality in arid areas, mature jujube trees in the experimental zone of Akesu City were studied in 2009. Irrigation water distribution, jujube growth, yield, water use efficiency and fruit quality were conducted based on surface irrigation, drip irrigation and micro-irrigation in the this study. The results indicated that the amount of leaching were decreased under drip irrigation and micro irrigation compared to the surface irrigation. As the consequences, compared to surface irrigation, the above irrigation systems saved water by 49%. The growth of the jujube tree for all of the treatments were no significant. In Jujube growth stage, the leaf area index, chlorophyll content and production were increased under drip and micro irrigation. Jujube yields were increased by 22% and 16% and water use efficiency (WUE) were increased by 240% and 230%, respectively. The fruit diameter, fruit weight, reducing sugar content and the content of Vc were significantly increased. Thus, it suggested that fruit quality and production were significantly increased under drip irrigation and micro irrigation. The research can provide a reference for water saving irrigation in arid regions. |
| Keywords: | irrigation fruits growth Jujube tree water use efficiency (WUE) yield fruit quality |
