Intercropping spp. (sugarcane) with the fungus together with bagasse amendment represents an innovative circular agriculture method that can enhance soil health, boost sugarcane yields, and increase farm profitability. Understanding the process by which degrades bagasse is key to optimizing this method.
This study aims to clarify the microbial and metabolic processes involved in bagasse degradation by in the sugarcane intercropping system.
Chemical composition analysis, metabarcoding sequencing, and metabolomic profiling were conducted on -degraded bagasse (DIBA) and naturally degraded bagasse (BA).
Analysis of chemical composition revealed that only acid detergent fiber (ADF) and crude protein content differed significantly between the DIBA and BA treatments. Metabarcoding sequencing showed that DIBA significantly altered the bacterial and fungal communities, reducing microbial diversity. Metabolomic analysis indicated an enhancement of biological metabolism, particularly carbohydrate breakdown, in the DIBA treatment. Key metabolites, such as glucose, cellobiose, and D-mannose, were more abundant in DIBA samples. In addition, unique metabolites such as L-alanine, serine, and oxaloacetate were detected in the DIBA treatment, suggesting more efficient bagasse degradation compared with natural processes.
The use of macrofungi such as can play a pivotal role in circular agriculture by transforming agricultural waste into valuable soil amendments. Future research should focus on the long-term impact of this system on soil quality and crop yield, as well as the underlying mechanisms, to further optimize intercropping systems and the use of fungi in agricultural waste management.
将[物种名称]（甘蔗）与真菌间作并添加蔗渣改良剂是一种创新的循环农业方法，可增强土壤健康、提高甘蔗产量并增加农场盈利能力。了解[真菌名称]降解蔗渣的过程是优化此方法的关键。
本研究旨在阐明甘蔗间作系统中[真菌名称]降解蔗渣所涉及的微生物和代谢过程。
对[真菌名称]降解的蔗渣（DIBA）和自然降解的蔗渣（BA）进行了化学成分分析、宏条形码测序和代谢组学分析。
化学成分分析表明，DIBA和BA处理之间仅酸性洗涤纤维（ADF）和粗蛋白含量存在显著差异。宏条形码测序显示，DIBA显著改变了细菌和真菌群落，降低了微生物多样性。代谢组学分析表明，DIBA处理增强了生物代谢，尤其是碳水化合物分解。关键代谢物，如葡萄糖、纤维二糖和D-甘露糖，在DIBA样品中更为丰富。此外，在DIBA处理中检测到了独特的代谢物，如L-丙氨酸、丝氨酸和草酰乙酸，这表明与自然过程相比，蔗渣降解更有效。
使用[真菌名称]等大型真菌可通过将农业废弃物转化为有价值的土壤改良剂，在循环农业中发挥关键作用。未来的研究应关注该系统对土壤质量和作物产量的长期影响以及潜在机制，以进一步优化间作系统和真菌在农业废弃物管理中的应用。
