油橄榄低温冻害调查与适应性分析

Investigation and Analysis on the Adaptability of Olive Tree under Low Temperature Condition

摘要: 本文通过对白龙江流域甘肃陇南宕昌沙湾、甘肃甘南舟曲立节，犀牛江流域武都龙坝、礼县龙林、西和西高山等高海拔种植基地和扩区驯化试验点不同品种、不同栽培方式、不同管理措施等因素的受冻情况进行了调查分析。结果表明：陇南油橄榄主栽品种抗冻性(越冬性)依次为阿斯(Ascolana) > 鄂植8(Ezhi8) > 城固32 (Chenggu32) > 莱星(Leccino) > 科拉蒂(Cotatin) > 奇迹(Koroneiki)。新引西班牙油橄榄品种依次为豆果(Arbequina) > 柯尼卡(Cornicabra) > 贺吉布兰克(Hojiblanca) > 曼萨尼约(Manzanill0) > 恩帕雷特(Empeltre) > 皮瓜儿(Picua) > 阿尔伯萨娜(Arbosana) > 奇迹(Koroneiki)。为油橄榄品种适应性研究和生产中选用品种提供参考。

Abstract: This paper makes the investigation and analysis of freezing situation in different varieties, planting methods and management measures of the high-altitude planting bases and test points in Shawan town, Lijie town which is along the Bailongjiang River basin and Longba town, Longlin town, Xigaoxiang town which is along the Xiniujiang River basin. The result shows that the frost resistance of main olive varieties in Longnan from strong to weak is as follows: Ascolana > Ezhi8 > chenggu32 > Leccino > Cotatin > Koroneiki. Spanish olive varieties were Arbequina > Cornicabra > Konica> Hojiblanca> Manzanill0 > Empeltre > Picua > Arbosana > Koroneiki. This study provides a reference for the adaptability research of different varieties and varieties selection of olive cultivation.
