Abstract:: Taking 3~5 year-old Zanthoxylum piperitum f. inerme makino as meterial,the flower and fruit dropping were studied;based on the above reasons，the rate of different female to male that were 20∶1，10∶1，4∶1，different plant growth regulator and other measures were applied to improve fruitsetting of Zanthoxylum piperitumf.inerme makino.The results showed that at rate of male to female 4∶1，the fruitsetting was the highest;spraying gibberellin，‘Zaofengling’ and sodium borate on flower had positive effects on fruitsetting of Zanthoxylum piperitum f. inerme makino，and water had certain effect on improving fruit setting percentage,while the effect of 2,4-D was not obvious,among them，50 mg/L GA₃ had the best effect.
