近年来,新疆阿克苏地区冬季频繁出现异常低温天气,大大超过了枣树的耐低温能力。尽管各级政府和林业部门根据气象预测,组织枣农在枣树越冬保护方面做了大量的工作,采取了多项措施,但枣树仍然多次受到较重的冻害。近年我们在生产中推广应用了一些枣树冻害的预防和灾后补救措施,并取得了一定的效果。现将技术要点简介如下。 In recent years, the Aksu region of Xinjiang frequently experienced unusually cold weather in winter, greatly exceeding the low temperature resistance ability of jujube trees. Although all levels of government and forestry departments have done a great deal of work on juvenile jujube protection in winter according to the weather forecast and taken a number of measures, jujube trees are still subjected to heavy frost damage many times. In recent years, we have promoted the application of some jujube frost damage prevention and post-disaster remediation measures in production, and achieved some results. Now the technical briefings are as follows.
