摘要
以2013年栽植的矮化"玉华早富"苹果幼树为试材,采用刻芽、轻短截、摘心、涂膜发枝素等修剪方法,研究了不同修剪处理方法对1年生枝条新梢生长和光秃部位萌芽率的影响。结果表明:刻芽处理的萌芽率始终显著高于其它处理,在萌芽期,刻芽处理的萌芽率最高,为97%。涂抹发枝素处理的枝条的萌芽率为0%,与对照之间无显著差异。在萌芽期至坐果期之间,处理的时间越晚,拉枝和刻芽处理的短枝比例越高,但总枝数量减少。在萌芽期后,刻芽处理对培养结果枝组有积极的意义;拉枝处理可减缓枝条新梢的生长。
‘Yuhua Fuji＇apple trees planted in 2013 were used as experimental material,the effects of bud-notching,light cutting short,pinching and coating branch pruning treatments on the sprouting and shoot growing of one-year-old branches were studied.The results showed that the budding rate of bud-notching always was significantly higher than other processings,in the bud,bud-notching treatment had the highest germination rate was 97%.The budding rate of applying growth branch processing was 0%,and there was no significant difference compared with control.Processing of the late time,the ratio of short shoot of branch pulling and bud-notching treatment was higher,but the total of the number of branches decreased.After bud germinating,bud-notching to the cultivation of fruit group had a positive meaning,branch pulling could slow the growth of new shoots branches.
