Abstract:: ‘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.
