矮化中间砧苹果树幼树的特点矮化中间砧苹果树幼树的特点是,根系不发达,易倒伏;中间砧段比在其上方嫁接的品种部分和其下方的基砧长得粗,特别是M26、M9等矮化中间砧,在嫁接接口部位,还易出现瘤状突起(群众称之为大脚);基砧部分加粗生长较慢,相对来说呈萎缩状。矮化中间砧苹果树
Dwarfing the characteristics of the rootstock apple tree saplings dwarfing the middle ancestral apple tree saplings are characterized by underdeveloped root system, prone to lodging; the middle anvil than the grafting above the part of the species and below the root anvil grow thick, In particular, dwarfing M26, M9 intermediate anvil, graft interface in the site, but also prone to tumor-like protuberances (the mass known as the big foot); part of the anvil thicker growth slower, relatively atrophy.
