  • This paper dealt with the effect of grafting and fertilizing on main trunk growth of young paulownia trees from seedlings with 3.0,3.5,4.0,4.5,5.0 m in height.The results indicated that first time grafting might promote height growth of 3-year-old young trees from seedlings with 3.0 m and 3.5 m in height prominently;second time grafting might promote the height growth of 4-year-old trees from seedlings with 4.5 m in height.The increments of height and breast-high diameter of those trees from seedlings with 4.0,4.5 and 5.0 m in height were higher than those from seedlings 3.0 and 3.5 m in height.Application of fertilizer could accelerate the growth of seedlings with 4.5 and 5.0 m in height.Seedlings with 4.0 m in height might grow over 6.0 m in main trunk height.

Abstract: This paper dealt with the effect of grafting and fertilizing on main trunk growth of young paulownia trees from seedlings with 3.0,3.5,4.0,4.5,5.0 m in height.The results indicated that first time grafting might promote height growth of 3-year-old young trees from seedlings with 3.0 m and 3.5 m in height prominently;second time grafting might promote the height growth of 4-year-old trees from seedlings with 4.5 m in height.The increments of height and breast-high diameter of those trees from seedlings with 4.0,4.5 and 5.0 m in height were higher than those from seedlings 3.0 and 3.5 m in height.Application of fertilizer could accelerate the growth of seedlings with 4.5 and 5.0 m in height.Seedlings with 4.0 m in height might grow over 6.0 m in main trunk height.
