我省苹果树,特别是幼树,在越冬期间,常会发生不同程度的冻害,使生产受到损失。因此,预防冻害,保证幼树安全越冬为生产上急待解决的问题之一。据国外报道,石蜡乳化液可预防苹果、桃树的冻害。但在我国尚未见有关报道。为了探讨石蜡乳化液对预防苹果幼树越冬伤害的效果,寻找使幼树安全越冬的新途径,我们于1985年秋～1986年春进行了本项试验,现将结果初报如下。

Apple trees in our province, especially young trees, during the winter, often varying degrees of frost damage, so that production losses. Therefore, the prevention of frost damage, to ensure the safe winter tree for the production of one of the urgent problems to be solved. According to foreign reports, paraffin emulsion can prevent apple and peach tree frost damage. But in our country has not seen the report. In order to investigate the effect of paraffin emulsion on the prevention of young apple tree overwintering injury and looking for new ways to make young saplings safe, we carried out this experiment in the autumn of 1985 to the spring of 1986.
