基　　金：We gratefully acknowledge the support provided by the:Earmarked Fund for“Modern Agro-industry Technology Research System”(CARS-01-46);National Key R&D Program“Research and Development of Biochar-Based Fertilizer and Microbial Fertilizer”(2017YFD0200800);Innovative Talents Promotion Plan of Ministry of Science and Technology(2017RA2211);Liaoning Revitalization Talents Program(No.XLYC1802094);Shenyang Support Plan for Young&Middle-aged Scientific and Technological Innovation Talents(RC180204). 摘　　要：Biochar produced from straw has been shown to improve soil physicochemical properties.This review introduces the fundamental concepts,the broad applications,and underlying theory of straw biochar returning.Current developments in biochar industry and the production practices prevalent among enterprises in China are critiques.This review analyzes current knowledge gaps,challenges,and opportunities in the industrial application of straw biochar returning.Biochar standards,the quantitative and qualitative analysis methods for biochar,and high-value-added products that are based on biochar are critically examined with goal of providing recommendations for future studies.We propose production and modification of biochar that is application oriented to enhance its fitness for purpose as well as long-term and large-space-scale field study to better understand its impact on soil properties and ecotoxicology.Finally,we make prospects for the future development of SBR,including constructing a standard system about straw biochar returning and promoting self-discipline of biochar industry and the establishment of a biochar-based agricultural production model. 关键词：Straw biochar returning(SBR) Biochar-based agricultural inputs AGRICULTURE China
