Abstract:: With one or two years old Carya illinoersis as materials,the effects of survival rate and growth vigor by split grafting and sidegrafting were compared and analyzed.The results showed that different age of seedlings should adopt different methods of grafting.The stem diameter of annual seedlings was thin，sidegrafting had higher survival rate than split grafting，but two annual seedlings should be adopted by split grafting，the survival rate as high as to 89.3%，two kinds of grafting methods seedling of high growth difference at a significant level，and thick growth difference was not significant.The growth of grafted was linearly correlated with stem diameter of rootstocks.
