基于文献计量学分析生物碳在黑土改良中的应用研究现状OA

This paper analyzed the research status of biochar in black soil improvement by using the method of bibliometrics with using"China National Knowledge Network"as the resource library.By excavating and sorting out the research results related to"biochar"and"black soil",the paper summarized the research results in this field.The analysis found that biochar had broad application prospects in black soil improvement.In recent years,the research results in this field have shown a rapid growth trend.The research hotspots mainly focused on how biochar affected the physical and chemical properties of black soil,how to regulate the microbial community structure and applied to the effect of black soil improvement,etc.Overall,future research should pay more attention to the mechanism of biochar on different microorganisms,explore its impact on black soil quality and crop yield,and provide a more scientific theoretical basis for the protection of black soil and sustainable agricultural development.More practice and exploration should also be carried out in the application and promotion of biocarbon to achieve the maximum benefits of biocarbon.
