北京几种落叶阔叶树适应性初步调研

通过对北京几种落叶阔叶树适应性初步调查,首次发现光叶榉在北京可以开花、结实并自然萌发长成幼株;根据调查研究结果提出了可以在首都优先进行行道树研究和应用的树种:青檀、车梁木、光叶榉、槲树、栓皮栎、黄连木等;另外,根据调查结果,提出了有必要在北京建立一行道树田间基因库的设想.

Preliminary Investigation on the Suitability of Some Deciduous Broad-leaved Trees in Beijing

It is first found that Zelkova serrata grows very well in Beijing whose seeds can turn into seedlings and then plants naturally during the investigation about some deciduous broadleaved trees in Beijing. It is proposed that 5 species could be used with priority for street trees, including Pteroceltis tatarinowii, Cornus walteri, Zelkova serrata, Quercus dentata, Q. variabilis, Pistacia chinensis, after the study and investigation on the suitability of those trees. In addition, it proposes a project constructing a field gene pool of street trees in Beijing as well.
