摘要
针对南方银杏形态外观和彩叶效果差等问题,以福建省长汀县策武镇南坑村的银杏树作为研究对象,在初步观测的基础上选择47棵生长姿态各异的银杏树进行优良个体的选择。本研究通过测量各植株的冠幅、枝下高、分枝角度、挂叶时间、叶色这5个指标并进行综合评价,利用隶属函数法筛选出适合东南沿海气候条件的优良景观个体若干株,为景观和育种等应用领域提供更多的参考。
Aiming atmorphological appearance and poor color leaf effect of southern Ginkgo biloba,the Ginkgo bilobasin the Nankeng village of Cewu Town,Changting County were taken as the research objects.On the basis of preliminary observation,47 ginkgo trees with different growth positions were selected for excellent individuals.In this study,the crown width,the branch height,the branch angle,the leaf hanging time,and leaf color of each plant were taken as indicators.and the excellent landscape individuals suitable for southeast coastal climatic conditions were selected by using the membership function method.
