摘要： This study evaluates the efficacy of buried straw bioreactor (SBR) technology in enhancing soil properties, CO2 efflux, and crop yield, specifically focusing on Indian cowpea cultivation within a greenhouse environment. Conducted at the Yuxi Demonstration Park in Fujian, China, the experiment utilized a randomized block design incorporating seven treatments with varying straw application rates (4.5, 6, and 7.5 kg m(-2)) and burial depths (20 and 30 cm) alongside a control group. The investigation revealed that SBR technology significantly increased soil temperature, CO2 efflux, soil total nitrogen (TN), and total organic carbon (TOC), contributing to a marked improvement in the biomass of Indian cowpea roots, stems, and leaves. Notably, the optimal results were observed with 7.5 kg m(-2) straw applied at a 20 cm depth, enhancing soil temperature by 1.5-2.0 degrees C and multiplying cowpea biomass by 2.1-6.4 times relative to the control. This treatment also led to the highest increases in soil TOC and CO2 efflux, demonstrating the potential of SBR technology for carbon sequestration and suggesting its application as a sustainable agricultural practice in cold regions to ameliorate the soil's physical and nutritional characteristics, thus supporting enhanced crop production. The study underscores SBR technology's role in addressing the challenge of agricultural waste through the effective reuse of crop straw, promoting the circular development of agriculture while safeguarding the ecological environment.
