庭院栽植的苹果幼树,虽然肥水充足,树势较旺,但由于枝条不够充实,停止生长晚,往往造成枝干冻害,影响翌年的树体生长。为了使苹果幼树安全越冬,应采取如下防寒措施。1.根茎培土:根茎进入休眠期晚,而且位于表层土壤,温度变化急骤,最易受冻。因此,在土壤开始结冻时,将根茎处培直径2～3尺,高1.5尺的土堆,对增强抗寒能力。
Young apple trees planted in the courtyard, although the fertilizer and water are abundant, the tree vigor is more flourishing, but due to inadequate branches to stop growing late, often resulting in limbs frost damage, affecting the following year’s tree growth. In order to make apple saplings safe winter, should take the following cold measures. 1. Rhizome soil: Rhizome into the dormancy late, and located in the surface soil, rapid changes in temperature, the most vulnerable to freezing. Therefore, when the soil starts to freeze, the roots and stems will be mined at a diameter of 2 to 3 feet and a height of 1.5 feet to enhance cold resistance.
