- 摘要:
- 以2年生苹果“烟富3号”乔化苗、中间砧苗、自根砧和1年生普通中间砧苗为研究对象,测定短截处理和普洛马林处理间分枝数目、分枝长度、分枝角度、分枝高度的差异,探讨短截和普洛马林处理对不同砧木类型的苹果苗木分枝与生长特性的影响,为生产多分枝大苗及缩短果树整形周期提供参考。结果表明:70 cm短截的2年生乔化苗与常规方法繁育的中间砧苗经1 000 mg?kg-1普洛马林促分枝处理,有效分枝数目、长度、角度适中,分枝高度合理,达到了理想的促分枝效果,为其提早整形奠定基础。
- Abstract:
- Choosing two-year-old apple seedlings ‘Yanfu 3’ nursery with vigorous rootstock,dwarf interstocks,own-rooted and one-year-old dwarf interstocks as objecs,the branching numbers,branching length,branching angles and branching height,in different cutting back and promalin treatment were counted and measured.The research investigated the influence of promalin and different cutting back treatments on the branching characters of apple seeding.In order to provide reference for improving branching ability of apple seedlings,shortening juvenile and shaping periods and so on.The results showed that,with promalin treatment 1 000 mg?kg-1 after 70 cm cutting back and two-year-old dwarf interstocks seedlings,the suitable number,length,angle of effectual laterals of tree trunk were good and appropriate branching height could lay foundation for early shaping.
