摘　　要：假死假活和枯顶,是银杏大苗移栽后常见的生长特异性。本文通过对兰州市城区多地银杏移栽定植后的假死、假活及枯顶等生长特异性及其原因进行分析,认为根本原因是“先生根、后发芽”次序发生颠倒,违背了根系生长发育决定树体叶芽萌发的一般规律。银杏移栽后出现这种特异性,是因为人们缺乏银杏基于树木学、植物生理学的片面性和模糊性认知。本文旨在提示在实践中对银杏科学管护,需对银杏生理和生态习性进一步了解,以提高对银杏景观绿化造林与管理水平。‘False death,false life and dead top’are the common specificity growth of Ginkgo biloba seedlings after transplanting.In this paper,the specificity growth of G.biloba after transplanting and planting in Lanzhou city and its causes were analyzed.It was concluded that the root cause was that the order of"first root and last germination"was reversed,which violated the general rule of root growth and development determining the germination of leaf buds.The specificity growth of G.biloba after transplanting is due to the lack of onesided and fuzzy cognition based on dendrology and plant physiology.The purpose of this paper is to suggest that it is necessary to further understand the physiological and ecological habits of G.biloba in practice,so as to improve the afforestation and management level of G.biloba landscape.
