摘要
对泡桐无性系毛白３３ 二年生幼树接干生长测定分析结果表明：接干苗木较未接干苗木能明显促进苗高为３０ 及３５ｍ 的泡桐幼树的高生长，促进苗高为４５ 及５０ ｍ 的泡桐幼树胸径生长。
This paper dealts with the effect of grafting trunk on two-year-old paulownia rtee growth and development from different height seedlings (3.0,3.5,4.0 5,4.5,5.0 m).The results indicated that grafting might promote height growth of two-year-old young trees from 3.0 m and 3.5 m height seedlings, and chest diameter growth of those trees from 4.5 m and 5.0 m seedlings and so did the volumes from 4.5 m and 5.0 m seedlings prominentoly,which laid theoretical basis for cultivation of high trunk and good quality timber of paulownia trees.
