Abstract:: Taking 5-year-old Luntai White Apricot as material，the effect of different branch bending angles on canopy microclimate and growth and fruiting of Luntai White Apricot were studied，in order to provide a reference for pruning.The results showed that different branch bending angles had significant influence on PAR，fruit-setting rate and yield of per plant.Canopy had good light condition and relative high temperature when the angle of branch was 60°，but humidity was lower than other angles.New branch growth，fruit-setting rate，yield per plant in 60° were markedly higher than that of the other angles.Experiment showed that the main branch bending angle in 60° was suitable for pruning Luntai White Apricot.
