摘  要：
以阿克苏地区主栽品种‘灰枣’和‘骏枣’为对象,发芽后进行冻害调查,根据冻害发生率,分析气象因素、树龄、品种、养分和水分管理对枣树冻害的影响效应,以解决阿克苏地区枣树安全越冬问题,明确生长季节影响枣树冻害发生的主要原因,为生产管理提供科学依据。结果表明:低温的过早来临、持续低温、极端低温是枣树冻害的直接原因;树龄越低冻害发生率越高;在阿克苏地区的主栽品种中,‘骏枣’抗寒性高于‘灰枣’,重视铁、锰、锌等微量元素肥料的施用、10月下旬前完成冬灌有利于提高枣树的抗寒性。冻后补救有利于恢复树势,最大限度的降低经济损失。

摘  要：
The condition of freeze injury on the main varieties of Ziziphus jujube cv.'huizao' and Ziziphus jujube cv.'Junzao'after sprout were investigated.According to the results of winter injury incidence,and the effect of the meteorological factors,age,varieties,and field management on freezing injury causes were analyzed.The purpose of this search was to let the jujube safely live through winter and reveal the main causations of freezing injury in Aksu Area.It could provide the scientific basis for jujube production.The results showed that the continued low temperature,extreme low temperature,continued extremely low temperature,temperature fluctuating during the dormant stage and the early arrival low temperature before deep dormancy were the direct cause of frost.With the age growing,the freezing injury incidence of jujube was declined.In the main varieties of jujube the cold hardiness of 'Huizao' was stronger than that of 'Junzao';in addition,we could improve the cold resistance by paying attention to apply the microelement fertilizer of Iron,Manganese,Zinc and finish winter irrigation before late October.After the freezing injury happened,must take the measures to remedy.Because it was beneficial to recuperate tree vigor and furthest reduce the loss.
