AbstractTo clarifythe effcts of differentagronomic treatment measures onthegrowth，rotknotnematode control efectiveness，and yieldof ginger.Fieldexperiments wereconducted ingingerplantingareas inShanxian，Shandong Province.Conventional fertilization treatment （CK，nitrogen fertilizer 50kg/667m2 ，phosphorus fertilizer 18kg/667m2 potassium fertilizer 60kg/667m2 ），nitrogen fertilizer reduction treatment （R1，nitrogen fertilizer ， phosphorus and potassium fertilizers the same as CK），soil fumigant treatment （R2，nitrogen，phosphorus and potassium fertilizers the same as R1，fumigation with 3O kg/667 m2 of chloropicrin），organic fertilizer substitution treatment （R3， organic fertilizer 3000kg/667m2 ）and microbial fertilizer substitution treatment （R4，microbial fertilizer 1OO kg/667 m²） were setup tocompare and analyze the growth status of ginger，root knot nematodecontrol effect，and yield of each treatment.Theresultsshowed thatthe plantheight，rotknot nematodecontrolefficiencyand yieldof gingertreatedwith R4 were the highest，which were 89.76cm ， 80.23% and 4516.36kg/667m2 ，respectively.The incidence rate and disease index of ginger root knot nematode were the lowest，which were 9.94% and 16.51，respectively.Overall，the results show thatusing microbialfertilizer instead ofconventionalfertilization can helpcontrol root-knot nematodes and increase theyieldof ginger.This studyprovidesareferenceforthescientificpreventionand controlof gingerrootknot nematodes and the sustainable development of related industries.
