低温冻害对油橄榄生长发育的影响及其防御措施

Effects of low temperature freezing on the growth and development of olive and its defense measures

为给油橄榄品种适应性的研究和生产中品种的选用提供参考依据,对白龙江流域的甘肃陇南宕昌沙湾、甘肃甘南舟曲立节和犀牛江流域的甘肃陇南武都龙坝、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的以不同方式栽培、在不同措施管理下不同品种油橄榄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)的强弱依次为阿斯>鄂植8>城固32>莱星>科拉蒂>奇迹;新引进的西班牙油橄榄品种其抗冻性的强弱依次为豆果>柯尼卡>贺吉布兰克>曼萨尼约>恩帕雷特>皮瓜儿>阿尔伯萨娜>奇迹。

In order to provide a reference basis for the research on the adaptability of olive varieties and the selection of varieties in productive practices, this paper investigated the cultivation of olive varieties in different ways and different measures and different management in the cultivation and breeding test points of high-altitude planting bases and extension areas of the on Lijie town, Zhouqu county, Gannan city; on Shawan town, Dangchang county; on Longba town,Wudu county ,on Longnan ctiy where in the Bailongjiang river basin.on Longlin town, Lixian county; Xigaoshan town, Xihe county, on Long＇nan ctiy where in the Xihanshui river basin in Gansu province. The result shows that the frost resistance of main olive varieties in Longnan from strong to weak is as follows： Ascolana 〉 Ezhi8 〉 Chenggu 32 〉 Leccino 〉 Coratina 〉 Koroneiki. Spanish olive varieties were Arbequina 〉 Cornicabra 〉 Konica 〉 Hojiblanca 〉 Manzanillo 〉 Empeltre 〉 Picual 〉 Arbosana 〉 Koroneiki.
