【摘要】 为探讨秸秆还田与微生物菌剂对亚表层土壤中氨基糖含量的影响，设置秸秆立秆还田施用菌剂（SMB）、秸秆立秆还田（SR）、秸秆不还田施用菌剂（MB）、秸秆不还田（NS）4个处理，并调查各处理下的土壤氨基糖、土壤有机碳（SOC）、土壤微生物碳（MBC）、植株在不同时期的干物质积累及玉米产量情况。结果表明，在0～20 cm土层中SMB处理下的氨基糖含量显著高于其他处理；SMB处理提高了土壤有机碳含量和土壤微生物碳含量；与SR、MB、NS相比，SMB处理下的玉米产量分别提高了4.46%、15.14%、18.33%；秸秆立秆还田配施微生物菌剂能够提高土壤氨基糖含量，并促进土壤中的有机物向玉米籽粒转移，从而有利于提高玉米产量。更多还原

【Abstract】 To explore the effects of straw returning to the field and microbial agents on the amino sugar content in subsurface soil, four treatments were set up: straw returning to the field with vertical stalks and applying microbial agents(SMB), straw returning to the field with vertical stalks(SR), straw not returning to the field with microbial agents(MB), and straw not returning to the field(NS), and investigate the soil amino sugar, soil organic carbon(SOC), soil microbial carbon(MBC), dry matter accumulation of plants at different periods and corn yield under each treatment. The results show that the amino sugar content under SMB treatment in the 0 ～ 20 cm soil layer is significantly higher than that other treatments; SMB treatment increased the content of soil organic carbon and soil microbial carbon; Compared with SR,MB and NS, the corn yield under SMB treatment increased by 4.46%, 15.14% and 18.33% respectively; Returning straw to the field with vertical stalks and applying microbial agents can increase the amino sugar content in the soil and promote the transfer of organic matter in the soil to corn kernels, which is conducive to increasing corn yield.更多还原
