AbstractTo elucidate the role of green manure in ameliorating production conditions in wheat fields，a field experiment wasconductedfrom2018 to2O2O inthe Southern Xinjiang region.High-fertilityand low-fertility wheat fields were selected，and 4 cropping paterns were established： post-wheat relay-cropped maize （CK），summer fallow （BK）， post-wheat planted and incorporatedrapeseed （YC），and post-wheat plantedand incorporatedsunflower（YK）.The impacts of green manureonsoilenzyme activityandwheat yieldunderdiferentfertilitylevels were analyzed.Theresults showed that incorporating green manure enhanced the activity of certain soil enzymes，while summer fallow had no significant efectonimproving soil tilage conditions.Forhigh-fertilitywheat fields，theYCtreatment increased soil urease and invertase activity by 69.6% and 52.6% ，respectively，compared to the CK treatment. The YK treatment increased soil alkaline phosphatase and catalase activity by 72.7% and 82.9% ，respectively，compared to the CK treatment.For low-fertility wheat fields，the YC treatment increased alkaline phosphatase activity by 148.4% compared to the CK treatment， while the YK treatment increased soil urease，catalase，and invertase activity by 97.2% ， 124.3% ， and 84.7% ，respectively，compared to the CK treatment.Regardingyield and yield components，nostatistically significant diferences in wheat yield were observed among the treatments in high-fertility wheat fields （ P >0.05）. In lowfertilitywheat fields，the yieldsof the BK，YC，and YKtreatmentswereincreased by 4.5% ， 24.1% ，and 28.6% respectively，compared to the CK treatment.The numberof grains perspikeandthousand-grain weightwere significantly higherintheYC and YK treatments thanintheCK treatment （P<0.05） .Overall， post-wheat planted and incorporated reen manure was beneficialfor improving soil tillge quality inlow-fertilitywheat fields and enhancing wheatyield.
