苹果矮化苗,具有树体生长矮小、适于密植、结果早、单位面积产量高的特点。矮化密植栽培,已成为苹果生产发展的总趋势。繁殖矮化砧或矮化中间砧苹果苗,都需建立矮化砧母本园,以提供矮化砧接穗和繁殖矮化砧自根苗。母本园一般多栽植矮化砧自根树,也可在原有苹果树上高接换头,使之成为矮化砧母本树。目前,我省常用的矮化砧
Apple dwarf seedlings, with short growth of trees, suitable for close planting, early results, high yield per unit area. Dwarf and dense cultivation has become the general trend of apple production and development. Breeding dwarfing an dwarf or dwarfing anvil apple seedlings need to establish dwarfing ancestor mother garden to provide dwarfing anvil scion and dwarfing anvil rootstock breeding. The mother garden is generally planted dwarfing ancestral roots, but also in the original apple tree high takeover, making it dwarf anvil parent tree. At present, dwarfing anvil commonly used in our province
