摘要: 为了给澳洲坚果在干旱地区进行抗旱节水生态园的建设提供理论依据。通过田间不同的灌水处理试验,研究澳洲坚果的耗水规律及耗水量与产量关系。研究结果表明:开花座果期、果实膨大期和果实油份积累期是澳洲坚果需水的关键期。其耗水量与产量不是无穷的简单的直线关系,并不是耗水量越大,产量越大。适宜的生育期灌溉定额为2806.09 mm,开花座果期54.22 mm,果实膨大期 104.47 mm和果实油份积累期226.69 mm。开花座果期灌水周期为10 d/次,果实膨大期和果实油份积累期为8 d/次。在澳洲坚果需水的关键期合理匹配水资源是实现澳洲坚果高产优质的基础和关键。

Abstract: The aim was to provide a theoretical basis for drought resistance and water conservation ecological Macadamia garden construction. The water consumption and production of Macadamia nuts were studied by different irrigation treatments in a field experiment, and the relationships between water consumption, water consumption law and yield were studied. The results showed that: water requirement was critical for Macadamia in flowering stage, fruit expanding stage and fruit oil accumulation period. The relationship of water consumption and production was not infinite simple linear. High water consumption could not result in high yield. The optimal irrigation quota was: 2806.09 mm in growth period, 54.22 mm in flowering and fruit-setting period, 104.47 mm in fruit enlargement stage and 226.69 mm in fruit oil accumulation period. The Macadamia should be irrigated every 10 days in flowering and fruit-setting period and every 8 days in fruit enlargement and fruit oil accumulation period. Water resource in these critical periods was the key factor for high production and quality.
