Abstract In Iran, pistachio (Pistachia vera L.) orchards are mostly irrigated by surface irrigation. In this research, the border surface irrigation method was compared to five different irrigation systems. The research was carried out for four years at the Pistachio Research Center of Iran (IPRC) in Rafsanjan. A split-plot design was used with six irrigation systems with main plots; surface, drip, subsurface porous pipe, bubbler, T-Tape, and pottery cylinder, and three subplots of 10%, 20% and 30% Class A Evaporation Pan (685, 1370 and 2055 m3 ha−1 year−1). Generally, seedling performance increased with level of irrigation. The best results for seedling height, trunk diameter, leaf number and leaf area were with the pottery cylinder and drip systems and the 30% irrigation treatment; the poorest results were with the surface and T-Tape systems and the 10% irrigation treatment. The highest salinity was with the subsurface system and the 10% irrigation treatment and the T-Tape system with the 10% and 20% irrigation treatments. The lowest salinity with the lowest irrigation treatment was with the pottery cylinder and drip system with the 20% and 30% irrigation treatments. The pottery cylinder system had the highest common thin roots at 60−90 cm, and the drip system had many thin roots at 30−60 cm. Overall, the pottery cylinder and drip systems were best for pistachio seedlings.

伊朗开心果(Pistachia vera L.)幼苗生长对灌溉方法和灌溉量的响应

摘要 在伊朗,开心果(Pistachia vera L.)果园大多采用地表灌溉。在这项研究中,边界地表灌溉方法与五种不同的灌溉系统进行了比较。该研究在位于拉夫桑詹的伊朗开心果研究中心 (IPRC) 进行了四年。六大灌溉系统与主地块一起使用了裂地设计;表面、滴水、地下多孔管、起泡器、T 型胶带和陶筒,以及 10%、20% 和 30% A 级蒸发盘的三个子地块(685、1370 和 2055 m3 ha−1 year−1)。一般来说,幼苗性能随着灌溉水平的提高而增加。苗高、树干直径、叶数和叶面积的最佳结果是陶筒和滴灌系统和30%的灌溉处理;最差的结果是使用表面和 T 型胶带系统以及 10% 的灌溉处理。最高盐度出现在地下系统和 10% 灌溉处理以及 T-Tape 系统和 10% 和 20% 灌溉处理。最低灌水处理的最低盐度是陶缸和滴灌系统,灌水量为 20% 和 30%。陶缸系统在 60-90 cm 处常见细根最高,滴灌系统在 30-60 cm 处细根较多。总的来说,陶筒和滴灌系统最适合开心果幼苗。灌水处理最低的最低盐度是陶缸和滴灌系统,灌水处理量为 20% 和 30%。陶缸系统在 60-90 cm 处常见细根最高,滴灌系统在 30-60 cm 处细根较多。总的来说,陶筒和滴灌系统最适合开心果幼苗。灌水处理最低的最低盐度是陶缸和滴灌系统,灌水处理量为 20% 和 30%。陶缸系统在 60-90 cm 处常见细根最高,滴灌系统在 30-60 cm 处细根较多。总的来说,陶筒和滴灌系统最适合开心果幼苗。
