Аннотация: In this study rhizosphere soil ofcorn at a milk stage was collected to investigate characteristic metabolites and their potentialfunctions. Total nitrogen, organic matters, ammonium nitrogen, pH values, available p hosphorus and potassium weredetermined by semimicro Kjeldahl method, potassium dichromate (external heating) method, indophenol blue colorimetricmethod, potentiometry, NaHCO 3 leaching molybdenum antimony colorimetric method and NH 4 OAc leaching flamespec trometry, respectively. In addition, UPLC Q/TOF MS was adopted for non targeted metabolomic analysis. As revealed byresults, the total nitrogen contents in soils collected from Dongchuang ( i.e ., DCMRS for 0.67 0.14 mg/kg lower thanfrom Fumin ( i. e ., FMMRS for short); moreover, both DCMRS and FMMRS were acid soils . DCMRS contains higher levelsof AN (Ammonium nitrogen), SOC (Soil organic carbon), and AP (Available phosphorus) than FMMRS. The amount of TN(Total nitrogen) contained in FMMRS soil was 2.410 0.422 mg/kg, which is higher than DCMRS. All data derived fromUPLC Q/TOF MS met the corresponding requirements for further analysis. Metabolites such as 2 m ethyl 1 propylamine,gamma butyrolactone and 3 m ethyl 1 butylamine were detected in DCMRS and FMMRS samples. Several pathways wereincluded, such as lipid metabolism, xenobiotics biodegradation and metabolism, terpenoids and polyketides, and amino acidmetabolism. Through comparison of FMMRS and DCMRS, metabolic pathways associated with nitroge n, carbon, andantibiotic metabolism including iron transport were significantly different between them. Taken together, FMMRS is morefertile, less acidic, and higher in nitrogen than DCMRS. © 2021 Friends Science Publishers
