Abstract：Inviewofthelowfertilizerutilizationrateofoff-seasonpepperproductioninhigh-altitudecoldregionsofChina， screeningsuitableenhancersforpepperinhigh-altitudeareas isofgreatsignificanceforincreasing yieldandfertilizer efficiency. Seven enhancer treatments，including 25% polyglutamic acidand polyglutamicacid leopard root powder，were setup，withclearwateras thecontrol.Single-factorrandomizedblockdesign wasadoptedfortheexperiment.Theresults showed that EMbacterial liquid treatment significantly promoted the plant heightof pepper，increasing by 14.04% compared with the control，and had the best yield-increasing effect，the yield was 3255.73kg⋅667m-2 ，anincrease of 35.74% The treatment with plant enzyme organic fertilizer had the highest soluble sugar content in pepper，reaching 0.425% . The treatment with polyglutamic acid leopard root powder had the highest soluble protein and dry mater content in pepper， whichwere 5.34mg⋅g-1 and 8.77% ，respectively.The 25% polyglutamic acid treatment significantly increased theavailable nitrogen，available potassiumand organic matter content in the rhizosphere soil of pepper，which were 87.03mg⋅kg-1 0 152.37mg⋅kg-1 and 4.35% ，respectively，increasing by 11.68% 23.40% and 1.28 percent points compared with the control.Inconclusion，diferenteancesavesigniicantdirencsineirefctsonteagonomictraits，yild，uality and nutrientcontent of rhizosphere soil of pepper.Theresearch results provide abasis for the scientific selectionof enhancers in pepper cultivation at high-altitude areas.
