冬季天气寒冷,新栽的幼树抗寒、抗冻能力差,要加强防御才能安全越冬,采用下述方法效果很好。 一、压倒埋土防寒法:此法可在落叶后土壤封冻前进行。先在幼树的根部堆30厘米高的土堆,然后将整个树体轻轻压倒在地面上呈一弓形,然后培厚约30厘米的温土,把树体全部用土埋住,并拍紧土堆,以防干旱和风吹。埋土时不要移动幼树的基部,压倒的树苗最好顺着当地冬季风多的方向,以便第二年扶直,扶直的最佳时间是第二年春季幼树萌芽时。
Cold weather in winter, the newly planted saplings cold, frost resistance is poor, to strengthen the defensive in order to be safe winter, using the following method works well. First, overwhelmed buried cold method: This method can be carried out after the leaves of frozen soil. The first root of the young tree piled 30 cm high mound, and then gently overwhelmed the entire tree on the ground was an arch, and then cultivate about 30 cm of warm soil, the whole tree buried with soil, and patted Mound, to prevent drought and wind. When buried, do not move the base of the sapling. The overwhelming saplings should preferably follow the direction of the local winter monsoons so that the next year, the best time to straighten and straighten will be when the young saplings are sprouted in the second year.
