Safe wintering method for young fruit trees

The invention relates to the technical field of fruit tree planting, in particular to a safe wintering method for young fruit trees. The safe wintering method is specially suitable for the young fruittrees less than 3 years; in the experiment, thickness and color of different mulch films and earth wall construction method are set, and sprout rate and sprout index of the trees in winter are detected. A thermal insulation wall is adopted to match with mulch for heat storage for the young fruit trees weak in over-wintering capacity, and the method has the advantages of on-site soil sampling, convenience in operation, less effort, low cost and the like, soil temperature can be improved remarkably, and thickness of frozen soil and over-wintering rate of the fruit trees are lowered. The methodcan be promoted in areas where northern young fruit trees cannot pass winter safely in open fields. 本发明涉及果树栽培技术领域，特别涉及种幼龄果树安全越冬方法，特别适用于3年生以下幼龄果树的安全越冬方法。试验设置了不同覆盖薄膜的厚度、颜色和建造土墙的方法，调查测定了树体越冬抽条率和抽条指数。针对幼龄果树抗越冬力较弱的特点，采用保温土墙配合覆膜蓄热的方
