摘　　要：分别以定植1年后的乔砧、矮砧富士苗木为试材,比较了3种整形方法对树体结构的影响。结果表明,对中心干上的分枝采取适当的疏剪措施,相比于中截中心干延长头和不进行任何修剪处理,更有利于保持中心干优势,增加树体的分枝量,并且分枝角度相对开张,枝展相对较小,利于高纺锤形树体建造。矮砧效果优于乔砧。The effects of three shaping techniques on tree structure were studied on 1-year-old‘Fuji’of dwarfing and seedlings rootstocks.The results showed that the proper thinning of the central trunk was more beneficial to maintain the dominance of the central trunk and increase the number of branches of the tree,and the branch angle was relatively open and the branch length was relatively short,which was conducive to the construction of high spindle tree.The effect of dwarf rootstock was better than that of seedling rootstock.
