选取扬桐野生优良单株进行种子育苗、扦插、嫁接等多种方式的繁殖试验表明，嫩枝扦插的成活率可达８０％以上。模拟杨桐的生境特点，进行栽培试验，表明落叶乔木和常绿乔木与杨桐以２：１：１０的比例进行树种混交方法，对提高它的成活率、生长量、枝条质量是有效的。通过不同采枝量对其生长量的影响试验可知，采取合理的修剪方式能保证杨桐的持续利用。 The selection of yangtong excellent single plant seed breeding, cutting, grafting and other means of breeding experiments show that the survival rate of softwood cutting up to 80%. The simulation of the habitat characteristics of Yangtong and its cultivation experiments showed that deciduous trees, evergreen trees and Yangtong trees were mixed at a ratio of 2: 1: 10, which was effective to improve its survival rate, growth and shoot quality. Through the different amount of harvest on the amount of its growth test shows that the use of reasonable pruning methods to ensure the continued use of Yang Tong.
