【摘要】 为探讨不同耕作方式与秸秆管理措施相结合对土壤固碳及碳组分的影响，设置深松秸秆还田（STs）、深松秸秆不还田（ST0）、旋耕秸秆还田（RTs）、旋耕秸秆不还田（RT0）4个处理，考察土壤容重、有机碳含量和颗粒有机碳含量。结果表明：深松处理土壤有机碳储量比旋耕处理增加了10.69%，颗粒有机碳含量增加了41.47%；秸秆还田处理土壤有机碳储量比秸秆不还田处理增加了27.14%，颗粒有机碳含量增加了17.92%。深松结合秸秆还田有利于土壤有机碳固存。更多还原

【Abstract】 In order to explore the effects of different tillage methods and straw management measures on soil carbon sequestration and carbon components, four treatments including subsoiling with straw returning(STs), subsoiling without straw returning(ST0), rotary tillage with straw returning(RTs), rotary tillage without straw returning(RT0) were set to investigate the soil capacity, organic carbon content and particle organic carbon content. The results showed that soil organic carbon storage and particulate organic carbon under subsoiling treatment increased by 10.69% and 41.47% compared with the rotary tillage; The soil organic carbon storage and particulate organic carbon under straw returning treatment increased by 27.14% and 17.92% compared without straw returning. The subsoiling combined with straw returning to field was beneficial to soil organic carbon sequestration.更多还原
