| 摘 要： | 以1995年建园、2006年嫁接的4个品种苹果树为试材,调查其树体生长特性,为低接换种和高纺锤形培养提供理论依据.结果表明:矮砧苹果低接换种和培养高纺锤形树体条件下,“红夏”、“红富士”、“嘎啦”、“粉红女士”4个品种幼年苹果树中心干生长速度快,低接换种后5a生树高2.8～3.3 m,中心干侧生分枝数量40～57个,且侧生分枝主要集中在2a生和3a生的中心干段上.其中“嘎啦”的总枝量最高为651个,“红富士”和“红夏”次之,分别为563和554个,“粉红女士”总枝量最低为440个.经过低接换种改造以后改变和增加了结果部位,促进花芽形成；改善了树冠的通风透光环境,增加了光合产物的积累,为提高果实品质和产量奠定了基础.

| Abstract: | Four varieties which were planted in 1995 and dwarf grafted in 2006 were used as materials to study the growth and photosynthesis characteristic of apple,to provide theoretical basis for the dwarf grafting and high spindle prune.The results showed that the juvenile trees of 'Red summer' and 'Gala' growth slower under the condition of low dwarfting and high spindle pruning than the top grafting in the first two year but faster in the following year.The height of the dwarf grafting trees were 2.8~3.3 m,the nu... |
