葡萄在哈密地区是埋土越冬的果树,很少发生冻害,但如果栽植方法不合理,肥、水管理不当,遇到低温寒冷气候,也会发生冻害,尤其是新植2—3年的小葡萄,冻害将会使直株死亡。一九八四年冬季由于气候较往年寒冷,哈密各农场定植三年以下的小葡萄园近5000亩遭受冻害,死亡率高达90%以上,使葡萄生产受到严重损失。为发展葡萄生产,对幼龄葡萄园的冻害进行了调查。
Grapes in the Hami area is buried in the winter fruit trees, rare occurrence of frost damage, but if the cultivation method is unreasonable, improper management of fertilizers, water, cold and cold weather encountered frost damage, especially the new plant 2-3 years of small Grapes, frost damage will make straight strain death. In the winter of 1984, due to the colder climate than in previous years, nearly 5,000 mu of small vineyards planted below three years in various Hami fields suffered frost damage with a mortality rate of over 90%, causing serious losses to grape production. In order to develop grape production, the frost damage of young vineyards was investigated.
