对33个薄壳山核桃无性系的6个树体性状指标进行比较分析、相关分析,树形分类以及薄壳山核桃在园林中的应用阐述。结果表明:地径、胸径、树高、冠高、冠幅在无性系间、无性系内均有极显著差异;无性系14号、“黄山1号”、无性系9号生长快速,可作为园林优系推广;相关分析中,胸径与地径、树高与冠高有极显著相关性,相关指数分别为0.92、0.96;树形指数为0.59~0.82,接近黄金分割点,树形美观,为圆球形、广卵形;园林应用方面,薄壳山核桃是很好的孤赏树、庭院树、行道树、混交林树种,应加以推广。
Comparative analysis, correlation analysis, tree classification and application of thin-walnut in the garden were carried out on six tree traits of 33 thin-walnut clones. The results showed that there were extremely significant differences in diameter, diameter at breast height, height at tree height, crown height and crown width between clones and clones. Clones 14, Huangshan 1 and clones 9 grew rapidly, In the correlation analysis, there was a significant correlation between DBH and height, crown height and crown height. The correlation indices were 0.92 and 0.96, respectively. The tree index was 0.59 ~ 0.82, close to the golden section, Beautiful, spherical, wide oval; garden applications, thin-walled pecan is a very good solitary tree, garden trees, road trees, mixed tree species, should be promoted.
