去年11月下旬,我省部分地区突遭寒流袭击,造成历史上罕见的果树冻害。在受害严重的地区,8年以上的果树主干受到不同程度的冻害,新梢和绝大部分花芽冻死;8年生以下的受害果树,自地表10厘米以上树干形成层受冻变黑,失去复活能力;幼龄树苗,树干韧皮部全部冻毁并开始腐烂,有些树苗自嫁接部位以上全部冻死,甚至整株冻死。面对这次严重的自然灾害,广大果农要积极行动起来,首先要请有关农业科技人员对受冻果园进行逐株清查,根据受害情

In severely affected areas, more than 8 years of fruit trees suffered different levels of frost damage, shoots and the vast majority of flower buds freeze-dried; 8-year-old victims of fruit trees above the surface of 10 cm above the trunk formation of cold and black, lost the resurrection Ability; young saplings, trunk phloem all frozen and began to decay, some of the saplings from the graft above all frozen to death, and even the entire frozen to death.
