摘　　要：利用法桐定干时截去的上部树干进行插干育苗,研究不同土壤、不同径粗、不同处理和不同季节,对扦插成活率和生长量的影响。结果表明:潮褐土更利于法桐插干成活和生长;不同径粗的插干成活率都达到了92%以上,随着插干径粗增大成活率稍有降低;使用ABT2号生根粉、经过刻伤处理,更利于法桐干条生根;秋季插干成活率、年生长量比春季高。The effects of different soils,different stem diameter,different treatments and different seasons on the survival rate and growth of Platanus orientalis seedlings were studied by using the upper trunks cut off to planting seedling.The results showed that meadow cinnamon soil was more favorable for the survival and growth of Platanus orientalis;the survival rate of stem cuttings of different diameter grades all reached more than 92%,and the survival rate decreased slightly with the increase of stem diameter;the use of ABT2 rooting powder and cut treatment were conductive to the rooting of stems of Platanus orientalis;the survival rate and annual growth in autumn were higher than that in spring.
