Effect of Vc Fermentation By-products on Straw Degradation Rate in Semi-arid Areas of Western Liaoning WANG Li,GAO Yi-nan,ZHU Xiang-nan et al(Liaoning Technical University,F(xiàn)uxin,Liaoning 123000)
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.

遼西半干旱地區(qū)長(zhǎng)期的傳統(tǒng)耕作伴隨著秸稈移走或就地焚燒,加速了土壤有機(jī)質(zhì)含量的下降1,進(jìn)而導(dǎo)致土壤質(zhì)量下降,既不利于環(huán)境保護(hù)又不利于農(nóng)業(yè)資源的可持續(xù)利用[2]。(剩余8824字)
