[Objective] To explore the chemical bud removal method of Atractylodes macrocephala Koidz., and determine the inhibition effects of 30.2% maleic hydrazide solution with different concentration at different periods. [Method] The chemical bud inhibition effects of maleic hydrazide with different concentrations against Atractylodes macrocephala Koidz. at different growth periods were systematically studied. [Result] The spraying of maleic hydrazide could completely replace bud-picking by hand and achieve the purpose of labor-saving, yield-increasing and efficiency-improving. The higher the concentration of maleic hydrazide and the earlier the spraying time, the better the bud inhibition effect; the plant height was related to the maleic hydrazide concentration and the spraying time, the higher the concentration, the shorter the plant; the later the spraying, the higher the plant; too early spraying and high concentration of maleic hydrazide would reduce the yield of Atractylodes macrocephala Koidz. [Conclusion] The spraying of maleic hydrazide in the range of 50.0 and 62.5-fold dilution during the budding period would increase the yield.
