摘要
对南宁市区内栽植的观花、彩叶树种及应用情况进行了调查。调查发现,新建绿地注重彩叶树种应用,所选树种都生长良好、适应性强;但观花树种配置稍显单一,有些树种应用频率过高,有些树种景观效果好、易于栽培却少有栽植;有些树种耐寒力弱,用做路树冬季枯梢、死株严重,应慎用;有些路树出现明显的虫洞和树洞,存在安全隐患。
An application survey was conducted for ornamental flowers and colored-leaf trees planted in Nanning.The survey results show that newly greening lands focus on colored trees,where the selected trees grow well,but the variety of ornamental flower tree is too little.Several problems exist： some trees are applied too much,some beautiful and easily-planting trees are seldom planted,some trees with weak cold-resistance planted as road tree have serious death rate or winter top-dry so that they should be chosen carefully.Some of the road trees have obvious insect holes and tree holes so that security problem exists.
