【摘要】 对贵阳花溪引进树种珊瑚朴与本地乡土树种紫弹朴进行5年多的播种育苗与栽培对比试验研究,结果表明,2树种在生长势、抗霜冻能力等方面存在显著差异.珊瑚朴树高、胸径年生长量显著大于紫弹朴,抗霜冻能力也较紫弹朴强,且落叶期较紫弹朴晚,可作为荒山造林和园林绿化树种推广应用.更多还原

【Abstract】 The comparative experiment of Celtis julianae introduced from Guizhou with indigenous species Celtis biondii of Kunming in sowing and cultivating over 5 years indicates that there are significant differences in growth and cold resistance of these two species.In detail,the height of Celtis julianae and its annual growth of breast diameter are much larger than those of Celtis biondii;the capability of preventing from frost damage of the former is also stronger than Celtis biondii’s;and the phase of fallen leaves of Celtis julianae is relatively later than Celtis biondii.Thus Celtis julianae can be served as a particular species for extensive application in afforestation and gardens’ greening.更多还原
