Abstract[Objective]To explore the effect of applying vc fermentation by-products (RAE + CBS)on the straw degradation rate in the semiaridareaofestLoedisudoldgoseiileeitaldd areof westeLiaongasthsdyr,ihopieldndcootsoilastereseahets.Byeasofsalluridii, acombinationoffeldexpeentsndsillboratoyexpetsasdoptedesuloieldsiicatlyeasdferao of RAE + CBS.The proportionoffattyarbonandolysaccharideinsoilorganicmatercomponntssignificantlyincreasdaftertheapationof RAE + CBS,whiletheproportionofromaticarbondecreasdsignificantlyThproportionofplysachaidecompoentsinorganicateromponents showedatrendofrstincreasing,thendecreasing,andthen increasingagainaftertheapplicationofhigh-doseRAE + CBS.The cellulase activity was significantly higher than that of the control groupafter the application of high-dose RAE + CBS,and the cellulase activity showed a sharp decline trend from 1 to 7 days after application.After the application of high-dose RAE + CBS,the β -glucosidase activity showed a trend of first increasing,then decreasing,and then stabilizing.[ Conclusion] The application of RAE + CBS has a positive effect on the improvement of semi-arid soil.The application of RAE + CBS enhanced the ability to decompose cellulose in straw degradation,thereby promoting the accumulation process of soil organic matter in the semi-arid area of westerm Liaoning.

辽西半干旱地区长期的传统耕作伴随着秸秆移走或就地焚烧,加速了土壤有机质含量的下降1,进而导致土壤质量下降,既不利于环境保护又不利于农业资源的可持续利用[2]。(剩余8824字)
