杂种马褂木在杨凌地区的引种价值分析

Research on the Introduction Value of Hybrid Tulip Trees in Yangling Area

  • 摘要: 对杨凌地区15年生杂种马褂木的生长情况、观赏性、健康状况等进行调查,以当地普遍栽植的同龄七叶树、栾树为对照,比较分析杂种马褂木的引种价值。结果表明:无特殊保护措施下杂种马褂木能够健壮生长,几乎无病虫害发生,无冻裂和日灼现象;在直径、树高生长量方面,该树种生长量最大,胸径生长速度也远大于栾树和七叶树;对3个树种的干形、冠形、枝形、叶形、花果形、生长整体一致性、抗污染能力等7个观赏指标综合评价结果显示,杂种马褂木得分最高。因此,杨凌乃至关中地区在未来的城乡绿化中可适当扩大杂种马褂木的栽植规模。

     

    Abstract: The introduction value of hybrid tulip trees was comparatively analyzed by observing the growth status, the ornamental properties, and the health condition of 15yearold hybrid tulip trees growing in Yangling area, Shaanxi Province. All the indices of the hybrid tulip trees were compared with those of the same aged and commonly planted buckeye and goldenrain tree species in this area. The results showed that the hybrid tulip trees could grow healthily without any special protection measures, the trees were not suffered from severe diseases, insect pests, frost crack or sunburn. The DBH value and height growth rates of the hybrid tulip trees were much higher than those of the controls. The comprehensive assessments with trunk form, crown traits, branch form, leave form, fruit shape, overall growth consistency and air pollution resistance among the hybrid tulip trees, the buckeye and goldenrain trees showed that the highest score was obtained by the hybrid tulip tree species. Therefore, it was recommended that the hybrid tulip trees could be appropriately extended to be planted both in the local area for urban and rural greening and afforestation.
