广西公路绿化树种选择研究

Study on Selection of Tree Species for Highway Afforestation in Guangxi

为了使公路绿化真正达到绿化美化公路的要求,针对广西公路绿化树种选择余地小、树种绿化档次不高、对环境适应性不强等问题,在玉林地区进行公路绿化树种筛选和对比试验。通过种植选择的方法,在22个参试树种中选出了适应性强、树型优美、色彩鲜艳的公路绿化乔木树种9个和灌木树种5个。并提出了一套与这些树种生物学特性相适应的栽培技术和管理措施。

Since the fact that tree species selection by highway afforestation is limit, afforesting the level lets drop, adapting to the environment capability falls short in Guangxi In order to genuinely achieve the target that highway afforestation is meeting to afforest to beauty highway The testing is staged in Yulin for tree species selected and pair-comparisoning By way of planting selection, nine arbor tree species and five bush tree species for highway afforestation that is strong adaptability, beautiful and colorfulshape was selected among twenty-two tree species Cultivating measures were point out according to theirs biology characteristics
