Abstract:: Taking Chinese cherry cultivar ‘Zhuji Short-Petiole Cherry’ as materials，the effects of PP₃₃₃on new shoot growth of Chinese cherry were studied.The results showed that PP₃₃₃ had good inhibition effects on new shoot growth of Chinese cherry.The main aspects showed that PP₃₃₃ inhibited vertically elongate of tree and branch，promoted enlargement of new shoot，and improved secondary branch of new shoot in a certain range of concentration.Among all PP₃₃₃ concentrations，spraying 2 000 mg/L and soil fertilizing 1.5 g/m2 were the best concentration.
