摘　　要：为探究不同树龄枣树高接改优对其嫁接成活率与生长的影响,以金丝小枣和乐金4号为试材,利用插皮接法进行高接改优,调查成活率、生长量、干径、树高和冠幅。结果表明,金丝小枣不同嫁接树龄之间成活率差异不显著,但一年生枝生长量差异显著,树龄越大,生长量越小。‘Jisi Xiaozao＇and ‘Lejin 4＇were used as experimental materials to research the effects of top grafting on survival rate and growth of jujube tress with different ages. Bark graftage was used for top grafting,and the survival rate,growth,stem diameter,plant height and crown breadth were investigated. The results showed that no significant difference was observed in survival rate between different ages of grafted ‘Jisi Xiaozao＇trees. However,significant difference was found in the annual branche growth of grafted ‘Jisi Xiaozao＇trees with different ages. The growth was negative correlated with the tree age.
