Abstract：To investigatethemechanismoftheeffectsoffertilizerapplicationrateonmetabolitesanddierentialmetabolic pathwaysincucumberleaves，thecucumbervarietyJinyou30wasusedasthetestmaterial，ndnofertlization（CFO）， reduced fertilization（CF0.5），conventional fertilization（CF1），and excessve fertilization（CF2）treatments were setup. Gas chromatography-masspectrometry（GC-MS）wasusedtoanalyzethechanges inleafmetabolomics，and themetabolic diffrences between CF0.5，CF2，and CF1 were compared.The results showed that compared with CF1， CF0.5 treatment screened14 differential metabolites，CF2 treatment screened16 differential metabolites，and CF0.5 and CF2 had a total of10diferential metabolites.These diffrential metabolitesare mainlydivided intoaminoacids，sugars，andorganic acids，and their relativeabundance generallyshowsa downward trend under CF0.5 treatment and anupward trend under CF2treatment.Thechanges indifferentialmetabolitesmaybecloselyrelatedtonutrientcontentinsoil，andcucumber leaves may respond to fertilization stress by accumulating amino acids and organic acids.
