矮化自根砧苹果苗繁育技术

Propagation of Self-rooted Dwarf Grafted Apple Trees

矮化自根砧育苗具有育苗简单、园貌整齐、结果早、产量高、品质好等优点,是世界苹果生产发展的趋势,但目前我国的苹果矮化自根砧嫁接苗的繁育技术相对薄弱,成为制约我国苹果苗木发展的一个技术难题。作者在生产实践及对前人育苗经验总结的基础上,从母本园建设、砧木繁育、苗木繁育、嫁接技术、嫁接苗管理、肥水管理和培养分枝大苗7个方面,对矮化自根砧苹果苗的繁育技术进行了论述。

Propagation of self-rooted dwarf is the development trend of the world apple,which with the advantages of simple seedling,trees uniformity,early bearing fruit,high yield and good quality.The breeding technology of self-rooted dwarf grafted apple trees of China at present is relatively weak,which has become a technical problem restricting the development of China＇s apple seedlings.Based on productive practice and seedlings experience,the breeding technology of self-rooted dwarf grafted apple trees was discussed from the aspects of female parent orchard construction,rootstock breeding,seedlings breeding,grafting technology,grafted seedlings management,fertilizer and water management and culture branches.
