树干纵向皮损原因分析及应对措施

引起树木主干树皮纵向损伤的原因很多,本文按照皮损的方位特征进行了分类:方位固定的皮损可由日灼、火烤等因素引起；方位不固定的皮损则可能为树木生长自然开裂、树体含水过多或过少、树干受病虫侵害、气温大幅骤降、雷击等因素引起。按照以上分类,分别针对树干纵向皮损出现的原因、方位特征和容易出现纵向皮损的树木特征进行了具体分析,简要说明了皮损处后期发展的两种情况,最后提出了皮损的预防和救护措施,可为树木养护提供有益的参考。

Analysis of the causes and corresponding measures of longitudinal bark damage on tree trunks

Abstruct: There are many reasons that can cause longitudinal damage to the trunk bark of trees. This article classifies bark damage according to their directional characteristics: bark damage with fixed orientation can be caused by factors such as sunburn and fire; Skin lesions with an unstable orientation may be caused by natural cracking during tree growth, excessive or insufficient water content in the tree trunk, pests and diseases, significant temperature drops, lightning strikes, and other factors. According to the above classification, specific analysis was conducted on the causes and directional characteristics of damage on trees, as well as character of trees that are prone to longitudinal bark damage. Two situations of the later development of skin lesions were briefly explained, and finally, preventive and rescue measures for bark damage were proposed, which can provide useful reference for tree maintenance.
